How to insulate the roof of the attic. The insulation of the attic from the inside if the roof is already covered: the order of work and useful tips. Layer # 4 - vapor insulation film

The insulation of the attic roof is one of the key stages of creating a reliable roofing cake, which is designed for a long service life. To ensure comfortable conditions for year-round accommodation in the attic floor of the house, it is important to choose a quality insulation and correctly perform its installation.

Functional features of the heat insulating layer of the roof

Competently performed insulation of roofing structures from the inside makes it possible to provide a favorable microclimate in the attic room. In the cold season, it will be effectively maintained heat, and in the heat thermal insulation will not allow air in rooms under the attic roof. To create an effective insulation of the roof, it is necessary to understand the intricacies of the installation technology of roofing pie and use quality materials and tools. Useful to use a familiarization video.

The insulation of the roofs of an attic type is carried out according to the same principles as the insulation of ordinary roofing structures, but increased requirements for attic roofs. This is due to the features of the design of the attic space, the walls of which are either formed by the roofs and the front of the house, or closely adjacent to the skates. For this reason, the air in the mansardes in the summer heat heats up very much, and in the winter it coolers.

Multilayer pancake pie consists of the following components (from the inner layer to external):

• vapor insulation layer;
• insulation;
• clearance for ventilation;
• waterproofing;
• roofing material.

The presence of all layers is necessary, since each of them performs a strictly defined function. Increased attention requires ventilation and thermal insulation layer of roofing pie, since the level of comfort during living in the attic floor of the house depends on their high-quality execution.

Choosing the insulation, it is necessary to pay attention to the material indicator as thermal conductivity. It characterizes the ability of the material to transmit heat into the room or out of the room. The lower this indicator, the material better protects against heat leaks, therefore, the smaller layer of the insulation can be used to achieve the necessary thermal insulation characteristics of the roof.

In heated room, the largest heat loss occurs through the roof, since in accordance with the laws of physics, warm air rises up. The heat penetrates through the roofing pie and is transmitted to the finish coating, which is covered with a layer of snow in the winter. Snow has a porous structure, and due to the internal air pockets, it acts as an external heat insulator at an air temperature below -2 degrees.

If the heat loss of the house through the roof is large, the roofing material is heated, which is why snow is taking. With a decrease in the air temperature, the lifting snow forms an ice crust. It is dangerous for roofing, since during freezing water has a negative effect on the outer surface of the roof. The ice, in contrast to the snow, is not a heat insulator, in addition, it is denser by structure - the ice crust on the roof significantly increases the load on the design. If the insulation is made from the inside correctly, the snow does not fall on the roof in the roof.

In the hot summer period, excess warmth is transmitted from the roof. The air can overheat so much that even air conditioners will be difficult to maintain a normal microclimate on the attic floor. Installation from inside the roof of a reliable thermal insulation layer will avoid similar problems. Of course, the air in the attic will be heated stronger than in the premises of the first floor, but the difference will not be uncomfortable.

Features of the roof of the roof of a mansard type

The insulation of the attic roof requires a special approach. This is due to its constructive features. If you compare the device of the ordinary roof and the attic, it is obvious that the main difference is the size of the ventilation space between the residential premises and the roof. The ventilation of the ordinary roof is ensured by the presence of an attic with auditory windows. The fan space of the attic roof is very limited - it is only about 10-15 centimeters.

Properly performed ventilation is extremely important when the roof roof roofing cake is arranged.. The ventilation gap between waterproofing and insulation contributes to the disposal of excess moisture from under the roof, ensuring the protection of the entire design and extended its operational period. In winter, the ventilation prevents the roof overheating and the formation of ice crusts on it. In hot weather, due to ventilation from under the roof, part of the heat is given, thereby managing the air overheating in the attic floor and the structural elements of the roof.

Selection of insulation

At the stage of preparation for the installation of roofing pie, you should decide on the choice of material for insulation. The number of layers and the thickness of thermal insulation depends on the correct type and technical characteristics. The modern building market presents a wide range of materials for insulation of roofing structures. Among the most sought-after:

• polyurethane foam;
• extruded polystyrene foam;
• glass gaming;

A foamed glass can also be used, various types of natural insulation for mounting from the inside (wood chips, seaweed, granulated paper, etc.).

There are four main criteria for selecting thermal insulation material.:

• coefficient of thermal conductivity;
• moisture resistance;
• fire resistance;
• environmental Safety.

Note! For insulation of the roof of an attic type, it is recommended to use the material, the thermal conductivity coefficient of which is from 0.05 W / m * to and below.

The higher the moisture resistance of the insulation - the longer it will maintain its functional qualities. The burning resistance indicator is an important criterion for ensuring the safety of the house. It is also important to take into account the environmental purity of the material and its safety for a person. But the last two parameters do not affect the durability and effectiveness of the insulation of the roof.

Mineral wool - insulation, made from melt rocks. The material is well holding heat, does not rot, resistant to temperature differences and exposure to aggressive media, almost does not absorb moisture. Mats of various thicknesses made of mineral wool, especially convenient to use for the insulation of the roof, if the step of the rafter corresponds to the width of the mat.

The glass gamble is made of glass melt, according to its properties, this type of insulation is close to mineral wool, but has a lower thermal threshold -450 ° C. It has good heat and soundproofing characteristics. Glasswater is resistant to freezing. Between the fibers, the moisture can accumulate moisture, so waterproofing must be performed correctly.

Minvata and Glasswater allow you to warm the root with minimal financial investments. The disadvantages include the need to create a thick layer of insulation and several layers of pair and waterproofing.

It is possible to insulate the roofing design from the inside using polymer materials - polystyrene foam or polyurethane foam. The benefits of polyurethane foam (gas-filled plastics) include high ability to maintain heat, ease, durability. Polyurethan does not miss steam and is not affected by moisture. Extrusion polystyrene foam allows effectively to insulate the roof - its thermal conductivity coefficient is 0.05 W / m * to. The material has hydrophobicity, does not miss steam. The class of flammability from G1 to G4 depends on the material brand. The disadvantages of polymer insulation can include their artificial origin and relatively high cost.

If there is a goal to build a house exclusively from eco-friendly materials, you can warm the roof with natural heat insulators. Despite the good indicators of thermal conductivity and environmental purity, various types of natural insulation have their drawbacks. Foamed glass features high fragility. Granulated paper, as well as mats from a cantham, straw, seaweed and similar materials are characterized by high flammability and require special skills when making mounting.

Mounting technology insulation

To understand how it is better to perform the installation of thermal insulation during the arrangement of roofing pie, you must familiarize yourself with the step-by-step instructions for the work. In general, it comes down to the following actions:

• preparation of space for the insulation mounting;
• laying of the heat insulating layer;
• fixation of material.

At the stage of preparation of the project of the rafter design, it is necessary to determine the step with which rafters will be installed. In this case, it is necessary to take into account that the rafter system should be reliable, that is, the step should not exceed the recommended values. If the type of insulation is selected in advance, it is recommended to install rafters so that the mats or plates of the insulation are among them from the inside the screen. This simplifies insulation technology and minimizes the waste of heat-insulating material.

Over thermal insulation, between the crate and rafters, waterproofing is stacked. Material is located in Vangest, styling begins with the bottom edge of the skate. Then the wooden counterbashes are mounted - their thickness creates the required ventilation clearance of the roof. Reiki can be attached to the rafters of nails, but it is better to use selflessness. The prepared construction from the inside between the rafter is stacked and the insulation is attached.

The rafting leg made of metal or wood is a cold bridge, since its thermal conductivity coefficient is much worse than that of the heat-insulator.

For this reason, insulating attic, it is not necessary to limitate the installation of the heat insulator between the rafters - on top of the already laid mats and the rafter is better to perform a solid thermal insulation layer. For a solid layer it is better to use a thinner insulation. This method improves insulation quality. The disadvantages include the fact that the rafters are hidden, and it is more difficult to use them further to fix other structural elements. To facilitate further work, it is necessary to correctly mark the location of the rafter.

On top of thermal insulation, a vapor-permeable film should be laid. Its use allows you to remove excess moisture. Then the prepared design is attached to the crate. At the final stage of the work, an internal ceiling cover is performed. Properly performed roof insulation allows us to use the attic floor all year round as a residential room in which a favorable microclimate is supported. For a detailed answer to the question of how to insulate an attic roof, it is recommended to pay attention to the thematic video with detailed instructions.

If the attic room remains non-residential, the air located in the underfloor space serves as good thermal insulation (along with the heating of the overlap). In the case of an attic, everything is not like this: there is thermal insulation is very close to the roofing material and the task is not only the insulation of the attic, but also create such conditions so that the entire roofing system serves a long time.

Immediately, let's say that all wood that is used in the construction of the roof should be processed by antiseptics. Really all: and crates and counter-crates, and rafters. All wooden details. It is also necessary to make them less combustible. To do this, they are treated with antipirens. All elements that are from the street side are processed by the compositions for outdoor work. All wooden parts facing the inside of the room, handle impregnation for internal works. If indoors use the composition for external work, the specific smell will remain for several years. If, on the contrary, wood outside can suffer: the degree of protection is insufficient. Therefore, do not save on this matter.

Yet. Before the description of how to insulate the attic roof with their own hands, it is worth reminding about what: the ventilation system should be organized in the undercase. For this, the skate is satisfied with special ventilation holes. Through them, the air from under the roofing material goes, carrying out excessive humidity. And to fall under the flooring roof it should through the skes. It is categorically impossible to do everything hermetically. From there there is a fence of air. Only so condensate will dry up and the roof will serve for a long time.

Proper insulation of mansardes

So that the attic floor was warm in winter and cool summer, there were no problems with high humidity, they did not intent on the roof, it is necessary to properly make the insulation of the roof. But in the case of the roof, insulation, steam and waterproofing is a comprehensive solution and one without another works very badly, or does not work at all.

If the broken roof is simultaneously the walls of the attic floor, the pie will be the following (from the inside):

• internal covering (drywall or lining);
• doom;
• vaporizoation;
• insulation (the thickness of insulation depends on the region and the parameters of the insulation, for the middle of Russia, it is about 200 mm);
• superdiffusion membrane;
• ventzor;
• doom;
• roofing.

The photo shows the insulation of the mallandoic roof in the graphic version. Please note: superdiffusion membrane is laid on the insulation (designated blue). Its appointment is to prevent the condensation formed into the insulation or leaked through the roofing coating of precipitations and take the steam that still got into Minvatu, providing her drying. Because with vapor permeability from 1500 g / m 2. This layer is often called waterproofing (so it is actually), only waterproofing vapor-permeable.

Laying waterproofing

Ideally, it stacked exactly as shown in the figure: wrapping the rafters and close by stacking on the insulation. Often, for savings, it is rolled over rafted, but not pulling, but making the sagging of 3-5 cm. This option works well too: the moisture falls on the surface, and then roll down and output beyond the roof. Here is another important point: the membrane should go into a catchment chute. Then the moisture will be excreted from the underpants space.

A few more points on laying the membrane. It rolls over the rafter, starting below. The first row is started in the gutter of the drain. The next rolled with a screwdriver at 10-15 cm. And so to the skate. At the skate of the membrane on both sides, cut down at the top edge and fixed. Skate along the rolling pin, descending from one and the other side of the roof. It turns out a coating by which water flows to the very water collection chute.

Parosolation and its laying rules

It is worth separately telling vaporizolation. This should also be a membrane. The polyethylene or polypropylene film will not fit: it does not have the characteristics. The vapor permeability of this layer (expressed in g / m 2) must be minimal. Ideally, zero is equal. That is, this layer should not miss the pair from the room in the insulation layer. When using mineral wool as insulation, this is very important: it worst it loses more than half of its properties, and freezing in the wet state and then melting, in general crouched into the trunk.

Therefore, the vaporizolation film is also placed with the occasion of one panel to another. Moreover, these joints are sampled by a special bilateral steamproof tape (it looks like a sticky rubber). An ordinary painting or stationery will not suit. They do not provide 100% protection against steam. In addition to the joints, all the adjunctions are also punctured: from the bottom, from the sides, on top.

A line is on vaporizolation. She marks the border from which the next layer begins (this is the magnitude of the screwdriver) and the line on which the canvas are fastening with scotch

Parosolation is attached usually to the lags of the stapler brackets or, as in the drawing of the inner crate on the installation of the trim. In this case, another venzor is formed, which will dry the finish and membrane. This gap is desirable, but not required. In principle, the lining can be mounted on top of the membrane.

Heat insulation

The better to insulate the broken roof - the question is a complex and unambiguous answer to it. Mineral wools are used, only rigid, density of 30-50 kg / m 3. Since the attic roof usually has a big tilt angle, then soft materials can slide. It is for this reason that it is better to take the plates. Although in this case you have to adjust the step of the rafter under the dimensions of the insulation: it should be 10-15 mm less than the width of the plate so that the material becomes the "versiper" between the beams and kept well.

We need to lay thermal insulation so that the cold bridges can as small as possible. For the middle strip of Russia, 200-250 mm mineral wool is usually required. These are several layers of mats. When laying between rafters, the slabs are placed so that the seams of one row overlap the following. The width of the insulation, as already said, should be slightly wider than the distances between the rafters. Then the stove becomes tight, eliminating the presence of slots. If the width is more / less, you have to cut the material. At the same time, the chance to get a smooth edge is small and there are many residues.

If the dimensions of the rafter does not allow to lay the entire insulation, the planks of the required thickness are stapped by the side of the room. Between them laid the remnants of the insulation. Top on it already attach vaporizolation and, if necessary, the crate for the decoration. Such an option is even better: the cold bridges are completely excluded, overlapping even rafters. This method requires slightly large costs when installing, but in the attic it will definitely be warmer, which will reduce heating costs.

How to insulate the roof: order of work

The devices of the attic floor themes and well, which allows us to stretch the end of construction. It is immediately necessary to put on the rafter and secure the superdiffusive membrane, the crate and roofing material on it. And the insulation of the attic can be made from the inside after a while.

But note: the waterproofing layer must be mounted together with roofing. This is the main mistake of many developers: they do not fit this membrane. As a result, or it is necessary to remove the roof and put it, or invent systems that allow you to correct this flaw. The whole problem is that a cheapest solution that guarantees the normal state of materials, in which case there is no.

Warm outside

If you do everything right away, the order of work is:

With this option, working with the insulation is easy: it is easy to lay it, it rests on the crate (laces).

Warming from the inside

This option allows you to move the internal finish for the required period (it will be useful if the lack of funds is felt). After installing the rafter system, that you need to do:

• roll and secure waterproofing;
• fill the crate (if necessary, a counterclaim);
• mount the roofing material.

For the first stage, these are all the necessary work. After the opportunity to continue, you will need to make a malic roof insulation from the inside. It will be not so convenient to work: you have to make a fencing design that will not push the insulation higher than necessary. The wool itself will have to somehow fix it: he strives to fall on his head. The order of work is:

Several comments on how to lay thermal insulation material. If these are matte from mineral wool of high density and their width a little more step between lags, everything is relatively simple: they themselves hold well.

If the rolled mineral wool is stacked, everything is more complicated. Doing the insulation of the attic roof from the inside, it is placed from below-up. Take the lace, construction stapler. Roll through your cotton, press it to the straps, secure a lace piece with brackets, drawing the letter Z. So fasten the first layer, followed by the second and the next.

In general, if you want the attic roof to be warm, it is better to use mineral wool mats of the required density of 30-50 kg / m 3. They are tough enough to keep the form well. Softy rolled materials on vertical surfaces or with a large slope are joined, settling down, the thermal insulation of the attic roof deteriorates.

The better to insulate the attic roof

As mentioned above, the most popular material for the insulation of the attic roof is mineral wool. It is good, but completely imperfect: moisture is afraid. That is why it takes so thorough protection from all sides to keep her properties.

Polyfoam (polystyrene foam)

The roof of the foam or extruded polystyrene foam - EPPS. Polyfoam (MARODS PSB-C-25, PSB-C-35) has good characteristics, but during burning it highlights harmful substances, although there are self-fighting brands (with special additives). Here they are better to use them for insulation of roofing.

The main advantage of foam: low price. It is mounted simply: the versus is put between the rafters, all the joints are closed with mounting foam. Making the insulation of the attic of the attic from the inside is convenient: order the plates of the desired size - by 10-15 mm more than the lumen between the rafters - and put them tightly. Due to elasticity, they hold very well.

From the roof side also leave the ventilation gap and laid waterproofing. But it protects more wooden design, as the polystyrene foam moisture is not afraid, it does not absorb it itself, steam does not hold. Here it also lies the main drawback. Since the material of the pair does not miss, a good ventilation system is needed in the attic, and this is additional costs.

The EPPS has the best characteristics: under equal conditions, its thickness is twice as fewer than the minvats of the specified density and one and a half times less than the polyfoam. He also has a locking system that reduces the risk of gaps, through which heat will fly away. Another plus: extruded polystyrene foams do not like mouse and insects, fungi and mold will not multiply on it. What limits its application: solid price. And still need a ventilation system.

Epps grades - Extrol, Styrex, Penoplex, URSA XPS, TEKHOPLEX, PRIMAPLEX (Primaplex), Styrofoam, Kinplast (Kinplast), Heat insolite, GreenPlex (Grinplex). With the fact that the technology is the same, there are some differences in the characteristics, so compare when selecting.

Not so long ago, a new type of insulation appeared: foamed polystyrene foam. It is applied in a liquid form to the surface, entering into the reaction with air, it increases many times in size, filling all the slots and forming a monolithic layer. This is the only one, perhaps, today a way to correct the situation and warm the attic to the attic, if when installing roofing, they forgot to lay a layer of waterproofing.

Ekwata.

This insulation has a good characteristic (thermal conductivity coefficient of 0.036-0.040 W / m² ° C), but the special application technology. It is necessary to organize a closed cavity in which the composition will fill. In the case of the mansard roof, the side parts are rafters, the leaf material (Feds, Gvl, Phaneur, etc.) is nourished from above.

A feed sleeve is launched into the formed cavity, from which a loose wool comes out under pressure. It fills all cavities by forming a single layer of insulation.

The main advantage is the eco-house compared to all the insulation described above: it holds a pair. You can absorb moisture up to 20% of the volume, and then give it away. That is, there is no need to organize a parobarrier: humidity is regulated naturally, as in the case of wood. The ventilation gap between the roof and the insulation should still be as well as the properly organized movement of the air masses in it.

Mansard - a favorite dwelling of poets, artists, creative and creative people. Thanks to new building materials, the attic floor can be used as a room under the roof as a residential or shopping room (zone) not only in summer, but also in winter (for winter accommodation). Abroad, competently designed and decorated attic and are at all relate to the category of bohemian housing.

In modern housing construction of the attic - this is not just equipped with a warm attic, this is an effective way to increase the functional space of a residential building. Noteworthy is the fact that in accordance with urban planning standards, attic is taken into account when determining the flooding of the structure.

Advantages of warmed attic:

• savings at the cost of materials during the construction of a residential building;
• functional area arrangement;
• original appearance of a private house with an attic;
• reducing heat loss through the underpants space.

Among the disadvantages: beveled ceilings, the need for additional insulation, complexity with the rational organization of residential space.

Most of the minuses of the attic are completely eliminated and with the right approach become advantages.

Preparation for mansard insulation

A specific attitude of the attic is the presence of an inclined ceiling. Moreover, on the standards of SNIP 2.08.01-89, "residential buildings" The height of the attic floor cannot be below 2.5 m. A decrease in height on an area not exceeding 50% of the total area of \u200b\u200bthe room.

Another features of the attic can be attributed:

• the dependence of the heat loss from the material from which the house was built: wood, cellular concrete, brick or their combination;
• the dependence of mansard engineering systems from existing in the house. This imposes imprints on technical solutions on the device of communications;
• a variety of architectural forms: broken, one, double roof;
• a variety of constructive solutions. The material for the manufacture of bearing elements of the attic can be wood, metal, reinforced concrete;
• specificity of placement location. The attic may be within the area of \u200b\u200bthe building or go beyond its borders with support for colons or a console removal of inter-fitted overlap.

Thus, making decisions on how to insulate the attic for winter accommodation should be proceeding from constructive features.

Note that work on the insulation of a residential building or an apartment is correctly performed outside the room, because This approach ensures displacement of the friction point towards the insulation mounted on the outside.

However, the insulation of the attic of the attic from the inside - a widespread option, because All surfaces that are subject to insulation are inside the indoors of the floor - ceiling, floor and walls. The exception is the fronton, which can be insulated within the framework of the insulation of the attic or at the same time with the insulation of the whole house.

Factors affecting the thermal insulation of the attic

Professionals allocate two key factors that have a significant impact on the heat loss level and the operational characteristics of the attic after the work on insulation.

• First, it is thermal insulation material. Taking into account the fact that the attic floor is the coldest room in the house, and it is supposed to perform the insulation of the attic of the attic with their own hands, you need to we suspend to choose a heater.

• Secondly, this is a waterproofing film. It is she who is designed to protect the insulation from moisture falling into the indoors of the attic from the outside (outside) through the roofing material, and from the inside, through the floor.

What is the insulation for the attic to choose?

For the insulation of the attic of the house, you can apply any thermal insulation material that has proven itself in practice.

Among the most popular materials are: cotton, foam, polyurethane foam and varieties. It should be remembered that the insulation for the attic is chosen taking into account the factors inherent in a particular home and, taking into account the level of skill of one who will be engaged in the installation of thermal insulation material.

Characteristics that determine the fitness of the insulation for use in a particular case are shown in the table.

Insulation	Stiffness (compression strength)	Heat conduction	Gigro-scope	Shrinkage	Weight	Installation on the broken roof	Cost
Mineral wool (basalt insulation)	-	-	+	+	-	+	100-140 rubles / m.kv.

How to insulate the attic from the inside

Features of the use of insulation of different types and types.

Soft thermal insulation materials:

• the insulation of the attic of the minorvata requires a competent selection and use of films. Thus, it is possible to eliminate the main disadvantage of watts - its hygroscopicity. The second, less significant minus - minor rigidity, is eliminated by reliable fixation of watts, as well as the use of more dense varieties. Thus, the wool saving is excluded. However, due to the environmentally friendliness of the components, the insulation of the attic of the Minskata from the inside continues to hold the leading position;

• the insulation of mansard glass gamble is rarely carried out due to the fact that the glass gamble is unsafe in terms of environmentally friendly material. Plus, creates difficulties in the installation;

• hansard insulation by foam. Used in case it is necessary to heat without significant losses in the height of the room. So that the foam performed its functions, the material must be orienting the foil layer inside the room.

Hard thermal insulation materials:

• hansard insulation with foam. Excellent and easy to install an option that has such a disadvantage as incomplete fit of sheets to the crate. In view of this, the space unfilled by insulation appears and the effectiveness of insulation is reduced. In addition, foam foam, and toxic substances are distinguished during combustion. And in conclusion, tight insulation poorly misses couples. Polyfoam's popularity is due to its low price;

• mansard insulation is a polystyrene foam (penopleypsex) is similar to the insulation of foam. The difference is the presence of a groove-crease system of fastening, which, justice, does not play an important role in the insulation of the attic. As well as in the greater density of the material itself.

Note that breathable soft insulation will be a good option, if necessary, perform insulation of wooden attic.

Sprayed thermal insulation materials:

• hansard insulation is an eco-tree. Material is 80% consisting of cellulose and 20% of wood. It has a natural antiseptic. This is completely eco-friendly material;
• medzard insulation polyurethanerette (PPU).

The widespread spread of sprayed insulation prevents their high price, as well as the need to attract specialists and using special equipment. At the same time, as evidenced by consumer feedback, the price is justified by a high level of thermal insulation. After all, the sprayed material fills the smallest gaps and eliminates the sources of heat loss.

The thickness of the insulation of the attic depends on: the type of roofing material, the height of the room, the presence of the heating system, the placement of the insulation and its type.

Recommendation. If chimney passes through the attic roof, basalt wool should be used. It begins to melt at a temperature of 1000 ° C, rather than smoldering as an eco-board and not melted as hard insulation (foam, penplex).

Waterproofing and vapor barrier under insulation

Since Vata is a leader among the materials for the insulation of the attic, and at the same time it is hygroscopicity, then the need arises to take care of the wado itself, protecting it with a film of hydro and vapor barrier. Otherwise, Wat wet and loses its thermal insulation properties.

For insulation insulation, apply:

• izospan (20-25 rubles / m.kv.). A vapor barrier film (membrane) has a double layer and surface roughness, due to which condensate is held;

• polyethylene film (3 rubles / m.kv.). The most affordable price is waterproofing material. But this film does not have the ability to skip steam;

• waterproofing membrane (30-45 rubles / m.kv.). Many manufacturers offer membranes for the roof, which distinguishes the ability to simultaneously hold moisture and skip steam.

• penofol (40-50 rubles / m.kv.). Folgized insulation.

Mansard insulation technology from the inside with their own hands

Complex thermal insulation provides for the implementation of such types of work:

1. insulation roof attic;
2. insulation ceiling attic;
3. insulation of the floor of the mansard;
4. warming of mansard walls.

Each of the stages has its own characteristics on which we will stop in detail. The insulation of the attic from the inside is performed if the roof is already covered.

Warming roof attic

It doesn't matter what roofing material covers the rafter system. The main thing is that it effectively copes with the task of preventing water from entering the indoor room. From the point of view of insulation, the type of roofing material does not matter - their thermal insulation properties are approaching zero. This means that the most significant losses of heat occur through the roof. Therefore, work on the insulation of the room begins from the roof of the attic floor.

How to insulate the roof of the attic from the inside - step by step instruction

• installation of a waterproofing film or membrane. This is a film that prevents water to the insulation, but does not interfere with the output of moisture from it. Thanks to which the insulation does not wet. The film is mounted from the skate to the cornice so that water, if it fell through the roofing material or condensed on it, flowed on the film outward. Before mounting the film, it is important to process the wooden parts of the rafter system of primer deep penetration;

• air layer. It turns out by arranging the crate. Allows the material to "breathe";

• installation of insulation. Mineral wool (or hard insulation) lays between the attic roof rafters. If the step has rafted more than 600 mm. It is necessary to make an additional crate before the styling of the waterproofing film.

  Vata is placed between the adjacent bars or the metal profile of the eye, so that there are no gaps. If such appeared, you need to cut a piece of watts, and close the gap.

  Masters recommend using mats from mineral wool, and not rolled material, because They differ greater density. It is also recommended to lay cotton in two layers with displacement. To cotton tightly sitting in a designed place, it can be strengthened with rope or nails;

  Council. If the monsard ceiling insulation is performed with a slope length of more than three meters, you need to make wooden jumpers between the vertical bars of the crate. Because Wat can "slip".

• installing vapor barrier film. The task of this film does not miss steam into the insulation. The optimal level of humidity is achieved by ventilating the room;

  Note. To isolate the rafters, some masters set a thin insulation between the paraparmer film and the finishing material.

  Laying the layers in a given order is important to ensure reliable adjuncing of films and insulation to the skate, endand, walls, window openings, etc.

• finishing material. Most often, plasterboard sheets, MDF or wood (board, lining) are used to finish the attic. Facing material is attached to a rapid system or a frame of profiles.

Increasingly, when erecting a private house, the owners plan to use the underfloor space as an attic. It is very important to ensure the comfort of living is no worse than on the full floors, for this is warming. Before insulate the attic, it is necessary to carefully examine this question.

Advantages of mansardes

The attic floor is considered heated room under the roof, while the height of the outer walls should be from 0 to 150 cm. Planning such a floor has the following advantages:

Drawing of a mansard floor

Heat area

When designing an attic space, you need to think about the heat of the roof and walls. The insulation of the attic make it possible to significantly save at the stage of construction or repair and fully monitor the process.

The insulation of the attic roof from the inside allows to significantly reduce thermal losses, since the heated air moves up. The heat shield of walls can be carried out both from the inside and outside. The choice of method depends on the technology of insulation of the outdoor walls of the entire building. Competently from the point of view of heat engineering, the material from the cold air is mounted.

If necessary, the thermal insulation material is also placed in the design of the overlap. In this case, the insulation plays the role of noise insulation and provides maximum residence comfort.

Wall insulation

To carry out the insulation of the attic floor and ensure the maintenance of temperature during the winter period, the following materials are used:

• styrofoam;
• extruded expanded polystyrenex (PESEROPLEX);
• mineral wool (glass gamble, basalt, slag);
• polyurethane foam (mounting foam).

These materials are most effective for heat shields. If necessary, thermal insulation can be mounted from the inside of the room, but it is best to mount the material from the outside. The insulation of the attic of the attic from the inside with their own hands has the following flaws:

• reduction of the useful space of the room;
• protection from cold only internal building volume, not including external fences;
• displacement of the dew point (condensate falling in the cold period) deep into the design of the outer wall.

But it is worth noting that this method can be used in any weather, it does not require an additional construction of scaffolding and scaffolding. Work can be performed without special qualifications.

To answer the question of how to warm the attic from the inside correctly, it is necessary to consider laying layers. It is important to ensure reliable protection of heat-insulating material from any types of moisture.

For this, steam barrier and waterproofing are used. The most important rule in the insulation of walls and any other structures: vaporizolation is always located on the side of warm air, and waterproofing - from the side of the cold. If you do not fulfill this conditions, the entire pie of the wall as a whole will work not correctly and soon it will require not only cosmetic, but more serious repairs.

The procedure for carrying out work for all types of thermal insulation is not significantly significant.. To ensure reliable thermal insulation, it is best to act in the following order:

• cleaning and alignment of the base (when using a mounting foam, it is recommended to improve the adhesion of polyurethane foam with the surface to moisten the base with water from the pulverizer);
• fastening waterproofing;
• mounting frame for fixing the insulation (if necessary);
• installation of the insulation and its fixing;
• layer of vaporizolation;
• interior decoration of the room (for fragile materials it will be necessary to install plasterboard sheets).

When using extruded polystyrene foam and polyurethane foam can be neglected with vapor barrier. Polyfoam when installing indoors with a normal humidity mode also does not need it.

Hearth roofing

The technique of insulation of the attic roof in most cases is to lay the heat-insulating material between the rafted. It is best to apply the following materials:

• mineral wool in the form of rigid plates;
• styrofoam;
• polyurethan.

It should be remembered that when working with the Minvata and the installation foam, the performer will require protective overalls. The thermal insulation of polyurethane foam is held in the project position due to adhesion (clutch) with the surface. To improve this quality before applying, it is recommended that the elements of the roof of water are recommended slightly.

When using mineral wool slabs, it is best to assign a step of rafter feet so that the distance between them clean was 580 mm. This will simplify the installation process when using standard 600 mm wide slabs and prevent the appearance of slots between the insulation and wooden structures.

The joints between the foam and rafyles are filled with mounting foam or sealant. Fasteners are performed with a recompication of special glue or nails. The adhesive composition should not contain solvents (alcohol, acetone).

How to warm the attic to your own hands? It is important to observe the next order of the roof layers:

• finish;
• doom;
• vaporizoation;
• rafters and insulation between them;
• waterproofing;
• windproof;
• doom;
• roofing material.

First, the carrying structures of the roof are mounted, after that, waterproofing and windscreen are stacked. After installing the upper crate, start laying the insulation. As windproof and waterproofing, it is better to use special vagism-proof membranes.

Staying insulation in the design of the overlap

To prevent increased audibility between floors, it is possible to put a 30-50 cm insulation into the overlap cake. Installation can be carried out under a screed or by lags. When using polyurethane foam installation of the lag is always required. When installing foam plastic under the screed, it is enhanced by additional reinforcing grids, the diameter of the reinforcement is taken 4 mm.

Calculation of the thickness of the insulation

Before you insulate the attic, it is necessary not only to choose the heat-insulating material, but also its thickness. It depends on the climatic area of \u200b\u200bconstruction and the thermal conductivity of the insulation. It is better to choose materials with a lower thermal conductivity value: how it is higher, the greater the thickness of the heat insulating layer will be required. The amount for private construction can be accepted.

You can perform a full-fledged heat engineering calculation using a fairly simple "Teremok" program. It is available in free access and is understandable enough to use. With this application, you can choose the thickness of the heat insulator or check already accepted.

Competent insulation of the attic from the inside will ensure the comfort of living and avoid problems during operation.

It is important to pay attention to all external surfaces to the same extent. The thermal insulation, selected correctly, is able to last for a long time and reliably protect the house from the cold in winter.

How to insulate the attic: methods and technology

In order to be warm in the house, it is necessary to produce competent insulation of the attic floor. We will tell you how to warm the attic to your own hands from the inside.

Mansard insulation technology from inside

• Features of insulation and materials for the insulation of the attic from the inside with their own hands
• Methods of mansard insulation do it yourself
• The order of insulation of the roof and walls of the attic
• Wall insulation

Mansard is an attic space equipped to accommodate people or any economic needs (greenhouse, office, etc.). Depending on what the placement, its layout and the roof type of the attic can be of different configurations, but general requirements, in accordance with which the insulation of the attic of the attic from the inside should remain the same.

The arrangement of the insulation in the roof of the attic.

Features of insulation and materials for the insulation of the attic from the inside with their own hands

It should be understood that this room, in contrast to all others, is colder, because From above has no "heat pillow". That is why the insulation of the attic of the house at home, performed with her own hands, should be especially high-quality. Based on this, the insulation should be selected, using which warming will be performed.

The complexity is that the surface is uneven, because Under the roof there are rafted beams that will have to go around. The waterproofing layer will need to be removed under the roof in order to drain the condensate. In the process of organizing work on the insulation of the roof and walls of the attic, with their own hands, it is necessary to take into account that the end walls also need coverage, because It is through them a huge amount of heat.

Scheme of mansard insulation.

Each private house has its own characteristic, form and configuration of the roof, wall material and roofing. Consequently, for each individual house there may be some special, clarifying recommendations, in accordance with which the warming of the roof and walls of the attic of the private house from the inside with their own hands. So that the insulation was high-quality and reliable, you need to choose the correct materials. The choice of material, using which it is better to insulate the roof and walls of the attic houses from the inside with their own hands, depends on the set of factors: the design of the roof, roofing material, climate in this area, etc.

Polyfoam is one of the least expensive and most popular materials, with the help of which you can insulate the attic of the private house from the inside with their own hands. It is easy to handle and install. However, it is distinguished by a small vapor permeability, which means that there may be raw in the room. So, if the attic will be used as a residential premises, it is better to insulate it with another material.

Correctly and qualitatively insulate the living attitudes with their own hands using polystyrene foam. When laying this material there will be almost no joints.

Mineral wool - excellent material in all indicators.

Having high strength, basalt minvat is fireproof, practically does not conduct heat and does not absorb moisture. Since this material has elasticity, it is well held at the installation site, resting the edges in the rafter. So it is best to carry out insulation of the walls of the residential attic from the inside of this material. You can warm my home with mineral wool correctly, even if you have never worked with this material before.

In addition to the insulation, it is necessary to arrange waterproofing, vapor insulation and ventilation system. Properly arranged waterproofing membrane will perform the following functions:

• provide the protection of structural elements from atmospheric precipitation;
• prevent moisture penetration inside the heat insulation.

Waterproofing needs to be laid on a layer of insulation. Among the waterproofing films are different:

• diffusion and breathable superdiffusion;
• anti-condensate waterproofing.

Parosolation consists of several layers of reinforced polyethylene film, which provides good protection for condensate design.

The ventilation system is needed in order to ensure the outflow of the spent and inflow of fresh air, and to effectively maintain normal air humidity in the indoor of the attic.

Methods of mansard insulation do it yourself

Hansard insulation, scheme.

There are several methods according to which you can correctly insulate the attic of the house from the inside with their own hands.

Warming between existing rafters is one of the most frequently used methods. With this method, the insulation is placed directly on the waterproofing, for the entire height of the rafter. The plates must be 10-15 mm wider than the gaps between the rafters.

Heat insulation above rafters. Immediately it is necessary to complete all finishing works from the inside, and the heat-insulating material is put on rafted under roofing.

Another popular way is the insulation of the attic under rafters. This method is not used in residential construction and low-rise houses, however, for industrial buildings, it is the best option.

There are also combined schemes. The most popular scheme includes insulation under rapid legs and between them. At the same time, the rafters themselves completely overlap. The vapor barrier film must be stacked over the layer of thermal insulation material. Among the shortcomings, some decrease in the useful space of the attic itself can be distinguished. This method of insulation is more effective, however, more complicated in the device. In this case, insulation is performed with a complete overlap of rafters and bars between beams and from the outside of the roof.

The order of insulation of the roof and walls of the attic

Scheme of mansard insulation: insulation, vaporizolation, waterproofing.

To insulate the attic with their own hands, you will need the following materials and tools:

• foam sheets or mineral wool;
• waterproofing film;
• wooden bars;
• vapor barrier film;
• scissors;
• sharp knife;
• construction stapler;
• nails;
• mounting foam.

First of all, it is necessary to put waterproofing along the rafter. The film is placed all over the entire height - from the bottom and to the ridge of the roof. However, this is done not in all cases, because The roof material sometimes also performs the functions of such an insulator. If the coating is made, for example, from roofing, it will be quite enough. In the process of installing the insulation, you need to know the coefficient of its thermal conductivity. These data are usually given in the Certificate of Products. Relying on these information should decide whether there will be 1 layer enough or you need to do a double laying.

When installing this material, you must remember that there should be some distance between it and the roof. This air layer is necessary to provide high-quality ventilation at the installation site of the insulation. The thickness of the air layer depends on the material of the coverage of your roof. If the material has a wavy shape (metal tile, tile), then the air layer must be at least 25 mm. In the cases of the use of the "flat" format (sheets of steel, rolled materials, asbestos cement) The distance between the insulation and the roof should be increased twice.

Another important point is the thickness of the plates of the insulator and the rafter can be different. If the plates are "thinner", the first layer is laid between the rafters, and the second must be put on rafters. If the plates are thicker, it is necessary to fill wooden slats on the rafyled.

To protect the heat-insulating material from excessive moisture, it is necessary to overlay vaporizolation. As you know, warm air tends to up and condenses there. That is why the device of such protection is mandatory. As a material for a vapor barrier layer, polyethylene film, parchment, foil materials, rubberoid are used. It is necessary to know that the vaporizolation material is stacked by the braziness, and the places of such joints are definitely stuck (the most convenient for all scotch). Fastening, as a rule, is made with thin wooden plates.

Wall insulation

The monsard walls are insulated if the roof of your house does not reach the floor of the attic. First, the walls need to fasten the rails for laying the heat-insulating and vaporizolation layers. The method of performing work is similar to the above described, however, it is necessary to pre-lay a waterproofing material. For the insulation, the sheets of Fiberboard were very well established for the insulation of the mansard. It is enough to work with them, because They can be attached to the help of screws or nails.

The high-quality insulation of the attic of the house, made with their own hands, allows you to significantly reduce the cost of heating, forms a favorable microclimate in the house and increases the service life of the structural elements.

Hansard insulation inside with their own hands (photo and video)

The insulation of the attic from the inside can be performed in different ways depending on the features of the house, the roof configuration. So that the insulation was high quality, you need to choose the correct material.

How correctly and how to insulate the roof

The roof is one of the most important structural elements of the building. It is exposed to a variety of environmental factors. Protects the house from high and low temperatures, atmospheric precipitation, solar radiation. If the roof is not insulated in accordance with the construction norms, heat loss through the roof can reach a third of the total heat loss at home. The insulation of the attic roof is not such a simple process as it may seem, although with your own hands. If your house has an attic floor, the question will inevitably arise how to insulate the roof. Many owners prefer to make an extra room there. First, it increases the overall residential area of \u200b\u200bthe house. And secondly, a new original room appears. During the construction of modern cottage villages, the attic rooms are planned initially. But in old houses you can easily remake the attic with your own hands in the residential premises.

Insulating material used for the attic roof, in addition to preserving heat in the house protects against acoustic oscillations. Therefore, it is important to decide what is better to insulate the attic roof.

Mansard insulation do it yourself

First you need to decide how to insulate the roof of your attic. To date, there are many options for thermal insulation materials. Installation of them easy to make with your own hands.

There are many nuances in the installation of the roof itself. The walls of the attic room are either the frontmostones of the building or rods, or adjacent to the skates. That is why the intensive movement of air begins through the roof. Because of what it is constantly subjected to temperature drops. To avoid the above problem, the insulation of the attic must be carried out in the sequence (from the inner layer to the outer layer):

CHEMA OF WASHING MANSARDA

1. Steam insulating layer.
2. Heat insulating layer.
3. Ventilation gap.
4. Waterproofing layer.
5. Directly roofing material.

If a high-quality insulation of the attic roof is performed, then the absence of the above layers is not recommended. It is especially worth noting the role of the heat insulating layer and the ventilation gap. It is due to the presence of all messages that the microclimate in the attic room is provided.

What is worth paying attention to when choosing insulation

When choosing a heater, it is worth a thermal conductivity at first. This is the ability to give and absorb the heat between the sacrifice space and the ambient air. Material is desirable with low thermal conductivity. First, it contributes to the best protection of the house from heat leaks. And secondly, a thin layer of heat insulating material will be required.

Properly insulated mansard

On the other hand, if there is insufficient insulation of the attic roof, the problems begin in the winter. In the winter months, the roof is covered with a layer of snow. Snow is a good additional heat insulating layer. But with insufficient insulation, it is covered with its own hands through the roof. Snow is gradually melting. The layer of ice is formed. Loda is not able to maintain heat. It has a mechanical impact on the design. Including the outer coating of the roof. This leads to its wear and gradual destruction. Sometimes because of this it is required after each winter to repair the outer roofing layer. With sufficient heat insulation, the snow does not melt in winter and does not turn into ice. The roof retains its design, and the snow provides additional protection against heat loss. Summer the situation is reverse. Under the influence of direct solar radiation, the roof is inclined to heat up and a suffocating atmosphere is created. If you lay a layer of insulation in sufficient quantities, this problem will not be a comfortable environment in the attic.

The main characteristics of insulation

When solving the question of how to insulate the roof of the attic home from the inside, in addition to thermal conductivity, it is necessary to pay attention to several more important parameters of the insulating material. The most important features:

• waterproofing;
• weight;
• fire safety;
• durability;
• material thickness;
• environmental characteristics;
• terms of operation.

Resistance to moisture is usually indicated by a manufacturer of a particular material. It is an important parameter, since the roof can give to flow and wet. Therefore, it is desirable to choose a material with water-repellent properties. If this is not available for any other reason, the layer will have to be additionally hydroizing. It also has a great value of the weight of the material. What he is less, the better. The total weight of the material is determined based on its relative density. Mineral wool materials should be with a density of 45 to 50 kg / meter cube. When using fiberglass, the density should be within 20 kg / meter cube. Higher materials will have excessive pressure on the design.

Insulating layers must be non-flammable. This is usually reflected in the technical documentation. As for durability, the ability of the insulation for many years to maintain its form is important. After all, the roof can be multigid. If the insulation is deformed, the roof will simply lose its protective properties.

What materials are popular

It is necessary to disassemble each separately to decide how to properly insulate the roof of the attic. Main materials:

• styrofoam;
• extruded polystyrene foam;
• polyurethane foam;
• mineral wool;
• glasswater.

The better to insulate the roof, solve you. But before that, you need to get acquainted with each material.

Hansard insulation foamflast

Styrofoam - This is a sought-after material among people, in front of which the problem is worth how to insulate the roof. It has a suitable thermal conductivity, low density and, accordingly, a small weight. Polyfoam provides good protection against water, it is quite inexpensive. On the other hand, it has certain disadvantages. Its main minus is insufficient fire safety. Also when installing with your own hands, it often crumbs. As a result, gaps between rafters appear. This in turn leads to a decrease in the thermal insulation characteristics of the coating. Another foam has a short service life.

Mansard insulation extruded polystyrene foam

It has better characteristics. First, non-combustible and ensures the necessary fire safety. It does not crumble over time. It has water-repellent properties. The plus is also something that needs a very thin layer of material. Material is not recommended to warm living spaces.

Hansard insulation Polyurethane foam

Polyurene Foolder It differs from previous options by laying. Thanks to this, there are no cracks. The material perfectly retains the form. It has the necessary fire safety and pushes moisture. The disadvantage of polyurethane foam is considered a bad ability to skip pairs. Because of this, in the attic room there may be increased humidity. The problem is solved by the organization of adequate ventilation.

Mineral Wool and Glasswater Widely known as insulation materials. Have a lot of advantages. Excellent fire safety, well kept heat, have a low density. Do not leave gaps and gaps when laying. The material provides excellent noise insulation, has a low price. The minuses include high moisture content and fervor.

Laying of thermal insulation material

With the insulation of the attic do not forget about hydro and vaporizolation

After selection of the material, it is necessary to prepare the room to install. The insulation of the roof of the attic begin with determining the step laying the insulation. We must try so that the sheets of the insulation are closely taken between the roof rafters. This will avoid the formation of gaps and further heat loss. If you are using foam, then this nuance does not matter for you. Waterproofing is placed in a mustache between rafters and a doom. Then, with the help of screws, wooden panels that provide ventilation are installed. The insulating material itself is mounted on the created platform between the rafter.

This will be useful when attaching a variety of designs in the attic room.

Handling of the attic roof from the inside with their own hands: analysis of technology

How to warm the attic roof from the inside of the room. How to insulate rational? We are determined with the choice and follow the simple step-by-step method of thermal insulation.

Construction of houses

Every year, more and more of our compatriots fall under the temptation to equip the residential attic in his home. This makes it possible to expand living space and adds some romance to the overall concept of the house, especially if you install the attic windows. Almost all new country houses are initially built with an attic, but in the old houses, cold attics are redoned, insulating, heating is heating and equipped. To winter in the attic, it was warm and dry, in the summer cool and materials served for a long time, it is necessary to understand the essence of the insulation technology of the attic floor and understand the processes occurring in it. Make the insulation of the attic roof with their own hands is easy, all work is quite simple, you will need only a partner and tool. The main thing is to do everything correctly, then the thermal insulation material will last long, wood rafters will not wet and does not rot, but as a result will not need a quick overhaul.

Why is the insulation of the attic roof

Attic is a special room, its walls are practically attracted to the surface of the roof and the ventilation gaps are no more than 10 - 15 cm. That is why the attic quickly cools in winter and is heated in summer. The whole area of \u200b\u200bthe roof is as if the drive of solar heat in the summer, through it most of the heat goes in winter. This is due to the thermal conductivity of the materials, of which it is made, and ventilation. For example, in winter, the heat coming from heating radiators rises upwards, spreads under the roof arch and safely disappear, since the roof material has a high thermal conductivity. The snow is tapping, turns into ice and destroys the roof material. And in the summer the surface of the roof is glowing and transfers the heat of the entire structure, in the end, even the air becomes hot and stuck. Two air conditioners will not be cope with such a problem.

The house with a classic cold attic is quite different. In it, the function of the thermal insulator performs snow on the roof in winter and air in the attic room. Filing heat-insulating materials on the semi attic plus air enclosed in an attic room, perfectly restrain the heat running from a residential heated room. As a result, even in the most severe winters, the temperature in the attic does not fall below 0 ° C - -2 ° C. Due to this, the snow on the roof is not pushing and serves as an additional heat insulator. In the summer, the air temperature in the attic can be adjusted, opening and closing the windows in the frontows, in fact it is the most real ventilation, which removes the excess heat from the attic, preventing overheating of the structural elements of the roof.

What to do with the attic? It is necessary to carefully heat the room, correctly selecting the material, its thickness, place of laying and keeping technology. For example, if you use insulation of insufficient thickness - on the eye, it may not be enough, the snow will be lifted, and will soon have to be prohibited roofing material, as the old one will come to complete disrepair. A sufficient width of the insulation will allow you to completely isolate the attic room from the roof, and competently made ventilation takes over the excess moisture and condensate from the underpants space. But first things first.

Mansard roof insulation materials

The choice of the best thermal insulation material for insulation of the attic roof is a very responsible task. From the type of insulation depends on which the thickness will be a "cake" of insulation and the number of layers in it. Due to the specifics of the place where the material will be applied, certain requirements are presented to it:

• Low warmth. It is desirable to take the material with the coefficient below 0.05 W / m * to.
• Low moisture permeability. Due to the fact that the roof can flow, the insulation material should be moisture-resistant and, if possible, do not wet or not lose its properties during wetting. If this condition cannot be observed, then the insulation must be hydroizing, eliminating wetting.
• The low weight of the insulation is extremely important not to overload the roof design. It is possible to determine the weight of the material by its density. For the insulation of the attic, mineral wool insulation with a density of 45 - 50 kg / m3 can be used, from fiberglass - with a density of 14 kg / m3. Heavier slab options (200 kg / m2) are not suitable.
• Fire safety. It is desirable that the material does not burn and did not support the burning.
• Ability to keep shape. Since the place of laying insulation is unusual - between rafters at an angle, then with time, light rolled material based on mineral fiber can crawl down, leaving above large gaps - empty spaces. Therefore, it is important to choose the material that for a long time will keep the form and dimensions.
• Stability to strong frost, temperature drops and the ability to withstand numerous shifts of defrost cycles / freezing.
• Durability.

The thickness of the insulation for the attic is calculated for each case individually. This can be done with the Special Online Calculator. To calculate, it is necessary to indicate the construction region, the thickness of the walls of the house and their material, the thickness and material of the insulation of the walls, the thickness and material of the floor overlap, as well as the thickness and material of the warming of overlaps. All this is extremely important for the calculations of heat loss, based on which the thickness of the insulation is selected. If you choose "on the eye", then in most cases the minvati layer 250 mm is enough.

Consider the most popular materials that are used for the insulation of mansard roofs.

Mineral wool or glasswater - One of the most successful solutions for the insulation of the attic from the inside, although not perfect. Mineral wool fits perfectly into the space between the rafters, without leaving the gaps, does not burn and does not support the burning, it weighs little and serves as an excellent heat insulator. Basalt cotton wool positions perfectly hold the form. But at the same time, it strongly absorbs moisture, like any wool, therefore, waterproofing from the roof and vapor barrier from the dwelling, as Pair of Minvat also absorbs well. The wet minvat loses up to 60% of its properties irrevocably, and its complete replacement is required. In addition, over time, it is joined and crumbles, poorly withstands mechanical loads.

However, mineral wool remains one of the best materials for the insulation of the attic roof with their own hands. It is worth it inexpensive, it is easy to work with it, and compliance with the right technology will allow to level its disadvantages. For different regions, the insulation thickness is calculated individually, but the minimum minimum layer of Minvati for the middle strip of the Russian Federation is 150 mm, in the colder regions, the thickness must be increased to 250 - 300 mm.

Polystyrene foam or styrofoam - The material is extremely popular on the market, which are trying to insulate everything, and what can, and what is not worth it. Against the background of apparent ideal characteristics - low thermal conductivity, negligible weight, moisture resistance and hard form, the foam plastic has significant disadvantages. First, different brands of polystyrene foams have varying degrees of fire safety from G1 to G4. And as practice has shown, for some reason the combustible foam g3 is used for insulation, which can be very bad. After all, the fire applies up, if the melting material of the attic of the attic will be lit, it will be unrealized to survive in it. Secondly, it is not very convenient to work with foam, as it crumble when cutting and installing, there are gaps between rafters that have to be embedded by all sorts of cunning methods. Third, the foam in time begins to crumble and collapse. Given all the shortcomings, the insulation of the attic roof is not worth doing to the foam. This material can be used only in those metas where it will be hidden behind the tie of the floor or layer of plaster.

Extruded expanded polystyrene foam - Excellent material for the insulation of the attic outside, i.e. If you put it on rafters under the roofing material. It is strong enough, no moisture is afraid, it does not burn, perfectly holds the form. And what is important - it takes a very small layer from 50 to 100 mm.

Polyurene Foolder - Modern material that is blown away with the help of a special installation, not leaving the slightest slots or gaps. This is an indisputable plus, especially since such a spraying is easy to avoid cold bridges in the form of rafting feet. Polyurethane foam is not afraid of moisture, does not burn, little weighs and perfectly holds the form. But he has another drawback - low vapor permeability, it almost "does not breathe." This means that indoors of the attic will always be unpleasantly wet, if not to equip forced ventilation.

Ekwata. - One of the most ideal options in the question, how best to insulate the attic roof. She also poices in all the cracks, not afraid of moisture, practically does not burn, little weighs, "breathes" and what is most important - absolutely eco-friendly, in contrast to all other materials. Her evaporation or random particles are not able to harm, in contrast it is mineral wool.

When choosing a insulation for the attic roof, pay attention not only to the characteristics of the material itself, but also the purely design features of its use. For example, the laying of mineral wool between the rafters allows, in case of the need to disassemble the "pie" of insulation and check the status of the rafter, repair them, and then the plates of Minvata can be easily put in place. If they are sprayed into the space between the rafters of polyurethane foam, then the rafters become almost inaccessible to revision. So everything must be treated with the mind.

How to insulate the attic roof from the inside

The most common method of insulation of the attic - from the inside, if it allows space or not other contraindications. To do this, insulation based on mineral wool, glass gambles and less often - extruded polystyrene foam. Still less often, polyurethane foam or eco-art.

Horry roof insulation scheme from inside

Compliance with the right "cake" of the insulation of an attic roof is the key to the durability of materials and comfort of living in the attic room.

Harry roof insulation cake (from the inside out):

• Finishing material.
• Parosolation membrane.
• Insulation - mineral wool or glass gamble.
• Waterproofing membrane, publishing steam and not passing inward moisture.
• Ventilation clearance with crate.
• Roofing material.

Vapor insulation film It must be used, if the insulation will be cotton materials. So minvatu can save from wet vapors of residential premises. If instead of mineral wool, polyurethane foam or eco-wool will be used, then vaporizolation is not needed.

Waterproofing Need in any case, regardless of the insulation used, it will protect the wooden elements of the roof design. As a waterproofing, it is necessary to use super-diffusion membranes capable of producing steam outside and not to pass moisture inside. Between the waterproofing film and the roofing material requires a ventilation gap from 4 to 10 cm thick depending on the type of roof. Through it, there will be surplus steam from the insulation.

Laying the insulation between the rafters of the attic roof

The insulation of the attic roof is better to produce at the construction stage of the house. Then all stages of work will be completed correctly. Before the start of insulation, it is necessary to determine where we will insulate. To do this, draw the drawing of the attic with the exact dimensions and note where the decoration of the inner space will be. For example, if the living space will occupy the entire area, including the roofing raft until the overlap, then the insulation it is necessary to insulate the entire rod of the roof. If the room will be cut off, i.e. Below between the skate and interior decoration will be free space, then it will have to warm up a strictly on the drawn scheme, leaving free space for ventilation. But then on narrow areas near the edge of the roof it will be necessary to insulate the overlap.

Consider the option of insulation of the entire roofing slope:

• Back at the construction stage, before siting roofing material, it is necessary to water the roof. To do this, from above, rafted filament the waterproofing membrane, we begin from the bottom up, making the reheast of at least 15 cm and sneaking the joints by self-adhesive ribbons. The film must be contacted not in the tension so that it does not break when frosts come. It must be stacked with the provis company not more than 2 cm per 1 m. To rafters, waterproofing are nailed by a construction stapler. If there is no such, then you can use galvanized nails with a wide hat.
• Next to above you feed the crate of wooden bars. Their thickness is selected depending on the required size of the ventilation gap, at least 2.5 cm. I fix the crate of corrosive screws. In order not to injure the film once again, we make holes in the bars in advance.

Important! For greater reliability, you can make two ventilation gaps: between insulation and waterproofing, between waterproofing and roofing. This will protect the material from wetting, if suddenly condensate will accumulate on the film.

• On the crate wept roofing material - tile, professional flooring, slate, metal tile. Here for installation of soft roofing first, you first need to penetrate the sheets of chipboard or moisture-resistant plywood, which will serve as the base for fastening.

• Works are moved inside the attic room. Unpack the insulation - mineral wool and let her get sequished and straighten. Cut on the necessary pieces. The width must be 20 - 30 mm more than the distance between the rafters so that the canvas keep the "Mrosusor".

• Pick up the insulation cloth into the space between the rafters. Press the middle of the canvas, and the edges straightened themselves. The thickness of the rafter should be 200 - 250 mm.

Important! The step between the rafters is convenient to pick up the size of the future insulation. Rolls are sold width 1200 mm. The step can be made 1200 mm or 600 mm, then the roll will need to be cut in half.

• On top of the insulation, a steam insulation material with an adhesive is 10 cm, the joints are sicking with a scotch. Fix to rafters with brackets or with the help of the crate.
• Put the crate from 25 mm thick cut.
• On the rails fix the finishing material.

If you plan to insulate the attic in an old or already built house and do not want to remove the roofing material, then you can snatch a little. The waterproofing film can be disseminated inside the attic, turning the rafted and a crying into the space between them. But in this case, wooden rafters are obtained unprotected in case of leaks.

Laying insulation under the attic roof rafters

A little less often is a method of insulation when the material is stacked inside the attic on top of the rafted, and not into the space between them. The main reason is so you can avoid cold bridges, which are wooden rafters. And so the thick fit of the heat-insulating material will ensure the absence of slots, and the free space between the rafters will serve as additional ventilation. A very successful solution if the monsard space allows you to reduce its at least 30 cm on each side.

Hansard insulation from the inside of the room:

• From the inside on the rafter, you feed the waterproofing membrane.
• Krepim to rafters The suspensions for the ceiling from the drywall so that they look at their p-shaped hole.

• We bring in the suspension insulation. Cut the canvas with a small nasha to eliminate the appearance of the gaps. As a result, a solid fabric of the insulation should turn out. We plan along the way where there are rafters.
• We close the insulation with a vapor barrier film, creating it with brackets.
• Put the crate for finishing material. For consolidation, use long nails 150 - 200 mm to break through the insulation and get to the rafter.

In principle, this method can be combined with the laying of the insulation between the rafters. The first layer will be between rafters, and the second will overlap everything, including the bridges of the cold.

How to insulate the attic roof outside

Warm the roof outside can only be on the construction stage or if you remove the roofing material. This method of insulation allows you to leave the attic space in its original form without loss of the area. Also, many design solutions suggest the use of rafters as decorative elements of the situation.

Horsery roof insulation technology

The insulation of the attic Outside is made only with dense slab materials. This include extruded polystyrene foam or penplex. It is not afraid of moisture, therefore does not require vapor barrier. "Pie" insulation of penplexes will look like:

• Plates of extruded polystyrene foam.
• Waterproofing membrane.
• Ventilation clearance with crate.
• Roofing material.

The indisputable plus of such a method of insulation is that rafters are available for inspection and repair at any time.

Laying the insulation on the attic roof rafters

Warming with extruded polystyrene foam on top of the rafter allows you to create a solid heat insulating layer without cold bridges.

• In order for the material to not slip from the roof, at the very bottom to the rafters you feed the board, width equal to the thickness of the insulation (from 50 to 100 mm).
• Elliprate the plates of the insulation in a checker order. It is necessary to start at the bottom, from the fixing rail.
• Fix them to rafters using special dowels with a mushroom hat.
• Withdraw the waterproofing film, starting from the bottom up, with the allen at 10 - 15 cm, the joints are sicked with scotch. Film is necessary to protect the material from leaks and condensate.
• Put the crate from bars with a thickness of at least 40 mm.
• Mount the roofing material.

No additional protection from the inside extruded polystyrene foam does not require.

Warming the fronons of the attic room must be together with the whole facade of the building, i.e. outside. The choice of insulation material depends entirely on the material from which the house was built and the host preferences. For example, if the insulation is performed using a hinged facade system, you can use mineral wool with vapor insulation and waterproofing films. And if the wet facade is planned, the foam can be laid under it. Do not forget that compliance with technology is the key to success.

Hor blind roof insulation with her own hands, construction portal

Construction of houses every year more and more of our compatriots falls under the temptation to equip the residential attic in his home. This makes it possible to expand residential space and

The insulation of the attic from the inside if the roof is already covered, it is necessary to perform. Even if the second floor in winter is not provided for use for housing, there will be large heat loss without heat insulation. To properly fulfill this difficult job, you need to competently pick up the insulation, observe when laying the order of the layers of thermal insulation cake and other nuances.

Features of mansard roofing

Many believe that the attic roof can be inspired by the same technology as the usual roof. The opinion is entirely incorrect. Mansard is not the second floor, but an attic room. For this reason, insulation technology has its own characteristics:

The comfort of living on the attic floor largely depends on the environmental purity of thermal insulation

Another feature is the fact that the technology of insulation of the attic roof has two ways:

Even if the inner space is separated by false walls, the specialists still advise the roofing rafts, and not partitions. Technology allows you to get a warm all the space under the roof.

Important! If you warm only partitions from false-walls, and the skates are cold, condensate is able to form in the ventilated space from the temperature difference.

Harry roof insulation methods

Depending on what step is insulation, the technology itself is different. The fact is that the roof can be erected or it is still at the construction stage. In the first case, warming up from the inside. The process is a bit more difficult, in addition, with this method, a little free space is closed. In the second case, insulation is performed outside, which is considered the best option.

How to insulate the roof of the attic outside

The advantage of the outdoor insulation is not only in the economy of the attic space. The technology allows you to save open access to the lines of the attic. Periodically wooden elements can be inspected for integrity, no fungus. In addition, free rafting legs designers are used for the decoration of the attic room.

Important! Outside, it is possible to warm the naked roof of the attic at the stage of its construction or after dismantling the roofing coating. The second option is used extremely rarely, only in the case of forced replacement of the roof.

For laying the heat-insulating cake, outside create a crate and a counterclaim

With outer insulation, only moisture-resistant materials are used. A cheap option is a foam, but it is fire hazard, it is damaged by rodents, has many other flaws. The best outer insulation is the extruded polystyrene foam. The material is known under the popular "Penopelex" brand. It is resistant to moisture and mechanical loads, on the roof can be used without vapor insulation.

The roofing pie circuit consists of the following layers:

• polyeplex plates;
• waterproofing;
• ventilated gap formed by Brucks, confined on the crate;
• roofing material.

Installation of plates on the crate on top of the rafter makes it possible to obtain a solid layer of thermal insulation without cold bridges, which are often formed with a loose laying of thermal insulation between the lines of the attic.

The process of insulation from the outside consists of the following actions:

1. At the bottom of the skate on the rafting legs are stuffed across the rail. The jumper will prevent the inclination of the insulation. The rack thickness and stoves must coincide.
2. Starting from the bottom from the rail, places the plates. They are placed in a checker manner so that the stakes take place. Each plate is fixed with a dowel with a wide hat.
3. After the insulation of the entire scope of the attic on the stoves, the waterproofing membrane is spread. Stripes at the joints are laid by the brass minimum 15 cm. Each connection is sampled by scotch.
4. From the racks of 40 mm thick create a counterclaim and the crate. The final layer is roofing material.

From the inside the attic penplex does not need to protect anything. There is no need to arrange vapor barrier. The gasket from the inside of the playproof layer is needed if the plasterboard is placed.

Outdoor warming of frontones perform simultaneously with skates

After insulating the skates, Penopelex is attached to the frontones, equipping the wet facade. However, here it can be replaced by basalt wool slabs if ventilated space is provided. Such a system is called dry or hinged facade.

How to insulate the roof of the attic from the inside

If the attic has already been built, you can only warm the roof from the inside. The heat insulation of the floor and the frontones is required. From the insulation of the waters of the roof optimally use Minvatu. Plates are considered the best choice, and not rolled material.

When insulating from the inside of only the seasplets and the upper part of the roof, which are ceiling of residential premises, the heat insulation still needs to be put on the slab overlapping the cold section of the cold section adjacent to the bottom of the skates

The insulation of the attic from the inside similarly requires the correct creation of roofing pie. At the stage of construction of the roof along the rafters, waterproofing is placed. The membrane is nailed with a nail with a big cap or shoot a stapler.

Important! Waterproofing is laid with a savory of about 2 cm / 1 m. Free stock will exclude the cracking of the membrane when the temperature drops.

From above, the waterproofing membrane from the ridges are stuffed. It can immediately lock the hard roofing coating. If a soft roof is chosen for the roof of the attic, then first from the ridges are picked up a counterclaim, and on top of a solid crate of plywood or chipboard.

Under the soft root decorate a solid base

When the roof is ready, it starts to warm it from the inside. For work, they are moved to the attic. Minvatu is cut into pieces of the desired size. If no slabs are selected for insulation, but roll material, then it is rolled along the floor. Give time to dealt.

The width of the Roll Minvati must be 30 cm more than the distance between the rafters

Minvata should be tightly used between the rapid feet of the roof. To do this, in width, the rolled material is cut off by 30 cm wider than the distance between the rafters. Technology helps prevent the formation of cold bridges in gaps. In addition, the insulation will be better to hold the gun.

Additionally, the Minvatu will hold the doom

So that the Minvata does not fall out, it is pressed by the crate. Reiki or metal profile fasten across on trim legs. In the future, finishing material will be fixed on the crate.

Minvatu is covered by vapor insulation by the attic

After the insulation of the whole roof, Minvatu is closed with vapor barrier. The film is raised under the crate, fasten the stapler to the rafter feet of the attic. The jokes of waterproofing are sicked with scotch. The final is the installation of a lining or other cladding on the crate.

How to warm the roof of a private house

The construction market offers a huge selection of thermal insulation materials. For insulation of the roof of the attic type, the following insulation are suitable:

1. Minvatu in roll form or plates are used with the insulation of the roof from the inside. The material strongly absorbs moisture, which requires protection with membranes on both sides.
   
   Minvat is suitable for the insulation of the roof from the inside
2. The popularity of foam is explained by the cheapness. However, the plates crumble, fire hazardous, have many other drawbacks. The foam on the extreme case can be laid on the roof when insulation from the inside. Best plates lay on the floor or sewing a false wall, where they will be hidden under a tie or plaster.
   
   Polyfoam is rarely used for the insulation of the attic
3. If the roof is insulated outside, polyplex plates are used. They on the ends have lock connections, which allows to obtain a hermetic seam. Penopelex does not require protection with moisture membranes.
   
   Penopelex is ideal with outdoor insulation
4. Polyurethane foam is applied on the rods of the roof by spraying from inside the attic. The foam fastest sticks to the roof, fills all empties, is the perfect insulation, but there is one minus. The attic becomes a thermos, since the insulation does not let the air. Establishment of effective ventilation will be required.
   
   Polyurethane foam spoke from the inside the attic
5. Eco-out plays special equipment to the created space between the roof and the crate with vapor barrier. Insulation is performed from the inside the attic. EcoCite is environmentally friendly, has the property of passing air.
   
   Eco-eyed insulate roof from the inside the attic

When choosing a insulation, it is important to consider that the sprayed materials do not allow the roof repair without removing them. Minvatu and plates of polystyrene can be removed. After repair work, thermal insulation is returned to its place.

How many layers of the insulation put on the attic roof

The thickness of the insulation depends on the material of the roofing and climate of the region, where the attic is located. In the southern regions there are enough 100 mm thickness of thermal insulation. For moderate zone, the parameter increases to 150 mm. In the northern regions, the thickness of the insulation is adjusted to 200 mm.

The layers are preferably laying two, especially if slabs use for insulation. They are placed in a checker order so that the joints of the first and second level did not coincide. When the rolled insulation is enough for the thickness, it can be put on one layer.

Dersighted roof insulation scheme

The scheme is a roofing pie. In the correct execution, it consists of the following layers (the calculation is carried out from the inside of the attic room of the attic):

• finishing from GLC, lining, plywood or other material;
• ventilation space formed by internal crate;
• vaporizoation;
• minvata;
• waterproofing;
• ventilation space formed by outdoor crate;
• roofing material.

The diagram of roofing pie with insulation from the inside is calculated from the face of the attic room of the attic

Depending on the material used and the method of insulation, the scheme may have minor changes. For example, for fasteners with outer insulation, vaporizolation is not needed.

How to prepare an attic roof to thermal insulation

The process of preparation for insulation begins with a roof inspection. First of all, the examination is subject to all wooden elements. They should be dry, without visible mechanical damage and places of mold. When a defect is detected, the element rafted is repaired.

All Wooden Roof Details are processed by antiseptic. The solution will protect wood from moisture, grinder beetles. In addition to the roof itself, the insulation itself is prepared. Minvatu is laid down on the floor so that it creates. If she pulled moisture from storage in the basement, the heat insulation is dried before laying.

How to insulate the roof of the attic from the inside with their own hands

In general terms, the process of insulation from the inside occurs in one scheme. However, there are some features. Often they are associated with errors perfect during the laying of roofing, as well as other nuances.

Hansard insulation from the inside if the roof is already

Under the condition of properly laying the roofing coating with waterproofing, insulate the roof from the inside the attic can be in two ways. In the first embodiment, thermal insulation is placed between the rafters, closed with vapor barrier, put the crate, mounted a cladding.

The second method is based on modern technology.

1. On the bollard and rafter feet tensioning with a larger markup. The distance between the strips is equal to the width of the insulation. Metal holders in the form of planks are fixed.
   
   
2. Niche filled with Minvata. The terminal holders bend so that the insulation does not fall out of the niches.
   
   
3. Minvatu is closed with vapor barrier. The membrane to the holders is fixed with plastic latches.
   
   
4. Cut holes under the windows, wiring, other communications. Holes are sampled by the film, if necessary, poured with sealant.
   
   
5. Metallic profile is installed on plastic latches of holders.
   
   
6. When the entire doom is fixed on the latches, fasten the plasterboard or perform the trim to other finishing materials.
   
   

Hansard insulation from within, if the roof is metallic

The minus of the metal roof is the formation of plenty of condensate. Even if there is waterproofing under roofing, after insulation, the ventilation clearance should be stored. The heat-insulating material is better to use polyplex plates, due to their stability to moisture. The insulation from the inside is labeled not between, but on top of the rafter feet.

When insulating from the inside of the metal roof, the insulation is placed on top of the rafter

You can use Minvatu, but first on the rafters fasten the waterproofing membrane. On each rafter foot, the suspensions are installed, a metal profile is fixed to them. Under the resulting clamp the insulation is settled, closed with vapor barrier. The profile fastens the final cladding. The formed ventilation space between the heat insulating pie and the metal roof will exclude the accumulation of moisture from condensate.

How to insulate a mansard roof for winter accommodation

An ordinary attic even with insulated roof is ventilated due to viewing windows. If the attic is designed for winter accommodation. Fronttones, roof and floor insulate so that the thermos is obtained. In this case, it is important to comply with the gaps between the roofing coating and the heat-insulating pie. Moist will be given through the ventilation space. If the insulation of the roof is made sprayed with thermal insulation, then the forced faning of the attic is equipped.

How to insulate the attic if the roof is without waterproofing

Lack of waterproofing is a roofer error. Such a roof can also be inspired, but on another technology. The optimal option is the spraying of polyurethane foam. In second place there is laying of plates of the fastener, as this material is not afraid of dampness. The lack of hydro and vaporizolation for him is not scary.

When using Minvati waterproofing laid over rafted

If you warm the roof of the minvata, close to the roof, the ribbing of the rafter legs, fasten the waterproofing. The suspensions fixed on the rafters, and to them profile. Further technology is standard. The insulation, steam insulation, fasten the facing under the crate. The disadvantage of the method is the impossibility of venting the rafters shrouded with waterproofing. Wooden elements rotten faster.

How to insulate the attic floor with a bartal roof

The roofs of the attic home are simple and broken. In the second embodiment, the design has a connection of the rafters where the insulation is needed. For this reason, for broken roofs, the flexible heat insulation is optimal.

It is easier to be insulation of a bunk roof of an ordinary attic. Due to the lack of complex areas with the beggars, it is convenient to use rigid plates. In addition, you can not create a ceiling at a two-bundle roof, but simply insulate the rocks.

The process of insulation is complicated, has many nuances for a particular case. The advice of professionals will help novice builders:

• the insulation does not fit the roofs, where the slope slopes are less than 13 o;
• in addition to the thermal insulation of the roof, it is necessary to warm the windows on the attic;
• the gap between the roof and the thermal insulation cake should not be less than 3 cm;
• it is important to comply with the priority of all layers of heat-insulating cake;
• if the thickness of the insulation is greater than the width of the rafting legs, they are increasing them with slats.

Inserted by Mosquir Play Minvati is better held on the inclined plane

The exact advice will give a specialist at the place of work, because it is easier to appreciate the device of a particular roof.

Conclusion

The insulation of the attic from the inside if the roof is already covered, it is better to conduct a specialist under supervision. Missing errors will lead to the formation of dampness. Attic will become unsuitable for housing, and wooden elements will begin to collapse from the fungus.
