Heat the wall in the apartment from within. Instructions for the insulation of walls from the inside as you can insulate the wall in the apartment

Create an acceptable microclimate in your home, protect it from drafts and dampness to help insulation of the room. The thermal insulation of the walls allows three times to reduce costs both on the heating of the room in the winter period and on its cooling in the summer. After all, the insulation acts as a kind of shield that impede the movement of air flows, protecting the structure from the effects of external factors. Unfortunately, the ability to warp the facade of the building is far from always. For example, thermal insulation of the end wall of the panel structure is valid from the inside.

The advantages of thermal insulation of walls indoors

Relatively low cost.
Implementation of insulation is possible at any time of the year.
You can insulate both the entire structure of the whole and individual rooms and even the walls.
Soundproofing of the room.

Among the positive points should also be allocated availability for self-fulfillment: it is under power to any owner. It is also important to know ways of warming walls and choose the best material for this.

Wall insulation methods from within

For thermal insulation indoors, the same materials are predominantly used as for insulation outside. The most demanded insulation: polystyrene foam, mineral wool and mixed insulation materials based on asbestos.

Wall insulation from inside plasterboard

Thermal insulation with the use of plasterboard sheets is a simple and fast way of insulation of walls. The minimum distance from the draft wall to the facial surface of the plate is three centimeters. The larger the distance, the, respectively, more insulation fit in the voids of the structure. This method of thermal insulation is suitable only for large rooms, as the wall in the process of mounting the insulation design is noticeably thickened.

The process of insulation of buildings from the inside is starting with the installation of a metal profile design at a distance of two centimeters from the wall. Frame is better to mount from a galvanized profile. On the sole of the guide profile, it is necessary to stick the ribbon to insulate the surface from contact with the plaster, thereby protecting drywall from the cold transmitted through a metal profile. Then the mineral wool is placed in the cavity of the resulting frame (between the rack profiles). The air layer between the wall of the structure and plasterboard is already insulation. However, the application of minvati or foam plastic repeatedly increases the heat resistance of the structure.

Due to its structure and elasticity, the material perfectly fills the design. The next step will be the installation of plasterboard. When insulating rooms with high humidity should not be saved. It is better to purchase moisture-resistant plasterboard. At the final stage, the trim of plasterboard plates by wallpaper.

Wall insulation from inside Minvata

Thermal insulation with the use of mineral wool is one of the most economical options. The advantages of Minvati can be attributed to the ease (which is very important when transporting building materials and the insulation of old structures) and low thermal conductivity. The effect of the "thermos" occurs due to the occurrence of the airbag between the mineral fibers.

Perhaps the only drawback of mineral wool is that it is sufficiently hygroscopic. Therefore, if you decide to warm the walls from the inside, you will have to take care of the vapor barrier to avoid the accumulation of condensate. In order to prevent absorption through the surface of the insulation of moisture, it is recommended along with the use of the main thermal insulation material to heat the walls from the inside by foam. This material has an extraordinary property - retains up to 97% of heat. The layer of the vapor polypoletor is applied to the frame of metal profiles after installation of minvati.

Penofol is a special, foamed polyethylene with aluminum coating in the form of a foil with vapor insulation, as well as soundproofing characteristics. The membrane of foam has small holes that allow moisture microparticles to move only in one direction. Penophol sheets have a small thickness. Due to flexibility, this material is easy to install. It does not require additional leaving during operation, which is also an indisputable plus.

Insulation of walls from the inside by the penplex

Heat insulation using extruded polystyrene forces even beginners who do not have greater experience in construction. There is nothing easier: the plates "Polyoplex", which can be purchased here http://penoplex-spb.ru, are attached with the help of glue on the wall. With this adhesive composition, the entire surface of the plate is processed. Small grooves along the edges of the slab contribute to a reliable fastening of the fastener and improving the tightness of the joints. Extruded polystyrene with smooth edges needs an additional sizing ribbon. Polyfoam is both glued and fixed with self-draws.

When insulating the penplex in conducting vaporizolation, there is no need, since the plate surface is a steamproof. The thin layer of plaster, applied to the grain (for better adhesion with finishing materials and increasing protection against fire hazard) The surface of the extruded polystyrene, protect the walls from damage and prepare for further painting or pasting with a wallpaper coating.

Technology of insulation walls from within

The process of thermal insulation takes place in several stages. The operation sequence depends primarily from the selected material. The insulation is either glued to the inner surface of the wall, or attached to a special design.

The most common scheme of insulation of walls from the inside, in which the layers of thermal insulation are arranged as follows:

Interior wall decoration.
Small ventilation gap.
Membrane for vaporizolation.
Insulation.

The whole process of insulation of walls can be divided into several stages.

Preparation of walls

When carrying out thermal insulation with mineral plates or with a drywall, it is not necessary to level the walls. It is enough to clean the walls from the peeling particles of construction and finishing materials, eliminate the protrusions that prevent the fixation of thermal insulation materials and carry out fungicidal treatment (protection against excessive room mold activity). Small irregularities are disguised during thermal insulation and finishing works.

Forming frame and installation of insulation

At a short distance from the wall mounted a frame of aluminum profiles or wooden bars (depending on the climate). It should be noted that wood is susceptible to dryness and deformation with sharp differences in temperature regime. The profile is fixed in the vertical direction. The frame thickness must certainly correspond to the thickness of the insulation, and the distance between the bars or profiles is calculated depending on the size of the finishing material (for example, a leaf of plasterboard). When insulated polystyrene, the frame is not needed.

Laying of thermal insulation materials begins after completing the frame assembly. In order to produce thermal insulation of walls from the inside, enough of one layer of the insulation. If there is a need to install the second layer, then, accordingly, it is necessary to install an additional framework for it. Often in the field of heating batteries, the insulation mounting is difficult. In this case, the foam layer should be paved.

Laying a pair-protective layer and finishing finish

The pair-protective layer protects the walls from the concentration in the voids of the thermal insulating material of excessive moisture. As a vaporizolyator, a film with a spraying from foil is most often used. Make sure that the brilliant part of the steam-layer is facing the inner wall of the room. The sheets of the pair-protective layer are attached to the brass. To improve the effect of the joints, they are sampled with metallized tape.

After the thermal insulation is completed, the surface is trimmed with drywall and is placed, and then painted or flies with decorative panels or wallpaper. As for the choice of finishing materials, there are no special limitations.

Other ways of wall insulation

In some cases, the foam is laid in space when laying walls. At the construction stage is also used penosopwhich is poured into hard-to-reach places and gaps.

From liquid materials use cellulosewhich is also poured under the plates and in the intervals between brickworks. In cellulose insulation, there are a number of flaws: it is a flamm and easily exposed to microorganisms and infected mold. To prevent this in cellulose mass, you need to add anti-epires and antiseptics.

One of the easiest, but notable ways of insulation of the walls is keramicOsolation. This is a liquid paste that is applied both on the surface of the wall and in hard-to-reach places. To achieve the effect of the wall, it is necessary to cover 5-6 layers of pasta, the consumption of which is 1 square meter - 250 ml. This makes such a type of wall insulation, though costly, but durable.

When conducting insulation, unsightly heating or water pipes, additional electrical wiring easily hide in the heat insulation niche. Therefore, the insulation of walls from the inside is a wonderful reason and improve the performance of the room, and improve the design of the room.

Recently, with a constant increase in energy prices, people seek to warm their apartments. This procedure really allows you to save on heating and make housing more comfortable, but at the same time it needs to be done correctly, so that you will subsequently encounter a number of problems. Therefore, in this article, we will look at how to perform the insulation of the walls of the apartment inside, and is there any sense to do this.

Is it worth insulating the walls from the inside

Heat the walls from the inside, of course, much easier than outside. However, I immediately note that this is not the best solution for a number of reasons:

after installing thermal insulation, the walls will stop heating at allAs a result, between them and the wall will be formed. This in turn can lead to the formation of mold and even the appearance of cracks on the walls;
at the arrangement of the insulation, inside there is no possibility to warm the overlap, as a result, the ceiling is also "cold", and condensate can be formed on it;
warming from the inside takes a living area. In a large apartment, this, of course, will be practically not noticeable, but for Khrushchev, where every square centimeter on the account, the useful area decreases significantly.

From here there is a question - why do internal insulation in general, if he has so many flaws? The fact is that it is not always possible to heat the walls outside. For example, if the facade of your home goes to the central city street or the square, the local authorities are unlikely to allow you to change it.

In addition, sometimes there is no possibility to perform outdoor insulation and for technical reasons, for example, if the wall adjoins the unheated elevator mine. So, the insulation of the wall from the inside in the apartment makes sense to implement in the following cases:

if there is no possibility to arrange the insulation outside;
if internal insulation is used as an addition to the outer. Even if the additional insulation on the walls will be quite thin - inside the housing will become much more comfortable.

After the insulation of the walls from the inside, it is necessary to provide high-quality ventilation of the room, since the apartment is essentially turning into a large hermetic thermos. This in turn will lead to an increase in humidity and deterioration of the microclimate.

In the remaining cases, it is better to warm the apartment outside.

Warming technology

The process of insulation of walls with their own hands from the inside includes several stages:

Each of these stages has its own nuances with whom we will read below.

Preparation of materials

It is necessary to start working on insulation, of course, with the preparation of materials. Since people often are interested, the better from the inside to insulate housing, I will say a few words about the insulation.

In principle, you can use any thermal insulation material, since the degree of thermal conductivity differs slightly. However, it should be borne in mind that the material will be placed in housing, but beyond. Therefore, the foam is better to refuse, but the mineral wool is a good solution - this thermal insulator is much more eco-friendly, moreover, fireproof.

In addition to the insulation, you will need the following materials:

parosolation film - prevents moisture penetration into the insulation. If not to use it, then the insulation is soaked with water, which entails a number of negative consequences;

material for mounting the frame - it can be wooden bars or boards. However, most often use the usual profile for mounting. In this case, you will need more brackets and guides;
plasterboard or other material for framework (lining, plastic panels, etc.)

To perform the purchase of all these materials, you need to pre-calculate the square of the walls. Knowing what the price for each of the materials, you can prepare in advance the cost of internal insulation.

Preparation of walls

So, how to inside the walls of the apartment we figured out. Now proceed to work.

As already mentioned above, before heating the wall from the inside in the apartment, it must be prepared. This is done as follows:

first of all, it is necessary to remove the old coating from the wall - wallpaper, tile, etc. If the wall is covered with gypsum putty or plaster, it is also desirable to remove it.
As already mentioned above, moisture will be formed between the wall and the insulation, as a result of which the gypsum will be twisted, accordingly, it will not lead to anything good. Remove the plaster can be removed using a chisel and hammer or a perforator included in the impact mode.

then be sure to treat the wall with antiseptic means, which will prevent the occurrence of mold. Instructions for the use of drugs are usually available on the package.

To achieve a maximum effect from insulation, it is necessary to heat and insulate the ceiling, i.e. The overlap that will lay down to the freezing wall. You can make it a wet method - stick the plates of Minvati and additionally fix them with a dowel. The surface of the insulation is plastering, on our portal you can get detailed information on how it is done.

This is completed on this process.

Fitting the ventilation clearance

The process of adjusting the ventilation gap is carried out at the wall waterproofing stage. It should be noted that many construction sites are offered to perform insulation from the insulation without a ventilation gap.

A large disadvantage of such a scheme is that a moisture is necessarily formed between the wall and the insulation, which is not going anywhere, which leads to the destruction of the wall. Therefore, it is better to abandon it.

The improvement of the ventilation gap is carried out in such a sequence:

attach wooden slats with a thickness of about two centimeters to the walls. You can arrange them horizontally in a step of about a meter. Attach the rails to the walls can be a dowel-nail.
Pre-racks must be treated with the protective composition so that they do not rot in the humid environment;
then you need to perform several things in the wall so that the ventilation clearance work. To do this, drill holes with a diameter of about 20 mm. So that the openings are not clogged, they need to be protected by a grid;
further, a vapor barrier film is attached to the resulting crate. Moreover, it must be located so that the ventilation gap is formed between the wall and the film.

To drill holes from the inside in a panel house for a dowel-nail, a perforator with a winning drill should be used.

Montage Karcasa

The frame is the vertical racks, which are located in a step equal to the width of the plates of the heat insulator. So that the insulation reliably lay down to the racks, the step between them can be done even on a centimeter less than the width of the insulation.

The process of assembling the framework is as follows:

first of all, apply marking on the walls, according to which the racks and guides will be located. It should be noted that the distance between the wall (vaporizolation in our case) and the guides that will be mounted on the ceiling and the floor must be no less than the thickness of the heat insulator so that the insulation can be placed inside the frame;
next, the brackets that will hold the racks are attached to the rains of vapor insulation on the markup. For each rack, use a multiple bracket. For the installation of the latter, screws are usually used;
then on the floor and the ceiling are attached guides for racks. They must be located strictly opposite each other so that the racks stood vertically. Therefore, before performing their installation, you should make sure the markup accuracy;
next, the racks are inserted into the guides and fixed by the brackets, as shown in the diagram above.

For cutting a metal profile, you can use special metal scissors.

By the same principle, the installation of the frame from BRUSEV is carried out. The only thing in this case are not used guides, so the racks are installed simply on the markup.

Installation of the insulation is carried out extremely simple - if the racks are located correctly, then the plates of Minvati are simply inserted between them, and there is no additional fixation. The only thing that did not have the bridges of the cold should be filled with insulation and the space between the wall and racks.

To do this, you can cut mineral wool strips of the required dimensions. Cut the plates you can routine wood with a tree.

Fibers Minvati getting on the skin and especially in the eyes, cause strong irritation. Therefore, when working with it, use personal protective equipment.

If slots are formed between the plates of minvata, they are also necessary to fill in insulation. In addition, it is necessary to ensure a tight fit of minvati to the floor and ceiling. I note that these, at first glance, small things should not be neglected, since they largely depends on the effectiveness of insulation.

After the insulation is laid, another layer of vapor insulation should be fixed on the frame. If the frame is wooden, then for its fixation you can use the construction stapler.

If the carcass is metallic, vaporizolation can be temporarily fixed with scotch. Subsequently, the film will be fixed with the material of the trim.

People often interest in the forums - how to insulate the wall from the inside in the corner apartment? In fact, the technology is no different.

Saving framework

As a rule, the painting of the frame in the apartment is carried out by plasterboard. So finally, I will briefly describe the technology of its installation and further finishes:

work should be started with cutting of drywall on the sheets of suitable size. To do this, apply marking onto sheets, then cut the cardboard mounting knife on one side by the intended line, after which the sheet is breaking, and then cut the cardboard on the other side;
prepared sheets should be attached to the frame with the help of self-samples, which should be located apart 5-10 cm. Self-tapping caps must be recessed;

then at the joints of the sheets you need to cut the champecker with a width of 5 mm. If the end is rounded, the brass is not needed;
then a special self-adhesive grid is pasted on the seams between the sheets;

next, the hats of self-tapping and joints between sheets are embarrassed by plaster powder;
after that, the entire surface of the walls is put off. On our portal, you can find detailed information on how to properly perform spatlement;
then the surface is polished by a special grater to which the grid is worn:
after that, another layer of finishing putty is applied and the final grinding is performed.

Perform grinding is necessary with bright lighting. In this case, you will see all flaws that need to be eliminated.

On this, the process of plating and finishing the wall is completed. Now it can be painted or, for example, shove wallpaper on it.

If the cladding or wooden panels are used as a plating, they simply attach to the frame of self-drawing. Accordingly, there is much less time on the trim.

Here, in fact, all information on how to insulate the walls of the apartment from the inside with their own hands.

Output

I told you how inspiring walls with minimal negative consequences. Therefore, do not try to simplify the process and move away from the above technology. Its compliance will allow you to make an apartment really warm and cozy.

Not all apartments are characterized by good thermal insulation. We will tell about the causes of the cold in apartments and explain how to insulate the dwelling without serious costs.

Doors and windows

Let's start with the entrance doors, often they simply produce heat from the apartment in the entrance. First, check how closely your door is closed, there is no draft. If the door closes closely - buy and stir the rubber seal. It is sold in business stores and hypermarkets. It costs about 100-250 rubles.

With plastic windows, the same story. You need to check how tightly they close and, if necessary, purchase a seal. You can also call the masters and adjust the window fittings - after a pair of years of operation, the window handles often break down and the window is simply not closed to the end.

Warming windows rubber seal

Plastic windows have another common problem - low-quality installation. Check if it does not blow from under the windowsill. Often, builders are left under the window of slits and emptiness. They must be detected and fill in the mounting foam.

If you have old wooden windows, insulate them with a grandfather's way: cotton wool is inserted into the slit and over with paint scotch. Remove the spring such insulation will be easy.

Reflectors of heat

In old houses, Khrushchev and Panel Nine-story stores, heating radiators are often standing under the window and warm the wall overlooking the street. To direct heat in the apartment you can set the reflecting panel behind the radiator.

Folgized heat reflector

The heat reflector can be foil foam polyethylene or foam. It is sold by rolls in construction stores. This material will serve as a screen that will send all the heat from the battery to the apartment.

Curtains and carpets

In winter, you can change the curtains to more dense. Curtains made of tight fabric not only adorn the room, but also delay heat, closed the heat outline.

Warm the floor can be proven in the carpets. Currently, there are a huge selection of not only "grandmother's", but also modern carpets with design for every taste.

If you live on the first floor, you can replace the floor covering on the carpet. Yes, it requires careful cleaning, but it is significantly warmer than any coating.

Wall insulation

In angular and end apartments there are often cold walls. The solution to the problem can be a wall cork cover, wool panels or again a carpet. A more difficult solution is to insulate the wall with plasterboard, but it will require repair.

Wall cork coating

Due to poor-quality construction or shrinkage of the house in the corners of the walls, cracks and emptiness may appear. They can be filled with mounting foam. But unfortunately, for this you have to remove wallpaper and plaster.

If the reasons for the cold are unclear

It happens that the batteries are hot, windows and doors are fine, but the apartment is still cold. Find out the cause will help the thermal imager. This is a modern device on the screen of which, the temperature of the objects is shown. With it, it can be clearly understood where the cold penetrates your house. The thermal imager is not necessarily bought, it can be rented.

Thermal imager

If fault of public utilities

In the heating season, the temperature in apartments should not be below 18 degrees. Temperature must be measured in the middle of the room, not less than one and a half meters from the walls and the floor.

If the temperature in the apartment is below the norm - write a statement to the management company. You must come with checking during the day. After checking, the act must be drawn up. Without an act, you will not be able to prove anything and achieve anything.

If you do not agree with the results of the check, do not sign the act and contact the housing inspection, which will handle the re-test.

If the check confirms that in your apartment colder standards, during the week, utilities must take action during the week. After that, another check should be carried out and an act is drawn up in which it should be specified, how much time you did not have enough heat.

Based on this act, you may require the management of the recalculation of the heating fee, as you have had low-quality services.

Not to freeze in the future

You can warm the apartment as much as you like, but it will not help if the heating system is outdated or the walls are frozen. To avoid problems, it is worth visiting the assembly of tenants, interested in the management company for what funds collected from the inhabitants go. If your home is old - you need to demand from the Code to speed up overhaul.

Integet to life at home, make sure that the neighbors do not make illegal redevelopments that can affect heat. For example, if the neighbors connect the loggia with the room and bring heating radiators on it - it will destroy the thermal circuit of the system. This can not be allowed if you know that someone destroys your home - contact the housing inspection.

Owners of corner apartments are particularly often faced with problems such as excessive dampness or cold. The heating system does not always work efficiently. Therefore, it is important to know how to insulate the wall in the corner apartment from the inside and minimize the energy flow. With the right approach, it turns out to significantly improve the microclimate in the room, make it more comfortable for living. In this material, we will tell you how to properly carry out work on the installation of the insulation and that it will be necessary for this.

The planning of angular apartments in terms of energy consumption for heating is not the most optimal due to the presence of two outer walls. And as a rule, in such conditions, even the presence of additional heating devices does not save tenants from the cold. Before the heating season, when the temperature drops sharply on the street, the warmth begins to leave the room quickly, because of which the apartment becomes cold, dampness and fungus appears. If the walls are not insulated, it will be uncomfortable in such a room.

When the central heating is turned on, the situation is slightly improved, because it becomes warmer, but the angular walls can freeze. This leads to damage to the plaster layer, peeling wallpaper. As a result, mold and different types of fungus begins to develop in such places. A similar microclimate causes discomfort and does not best affect the health of residents. Due to damp and low temperatures, colds for many inhabitants of corner apartments become familiar.

A bit of theory: dew point

Construction is used by the concept of "dew point".

The dew point is called the temperature at which condensate is formed (moisture from the air turns into a drop of water). With regard to the enclosing structures of the house, such a point can be located on the walls of the wall outside or from the inside and in its thicker.

In the period of high humidity and low temperatures, the microclimate apartment contributes to the formation of condensate. Due to the incorrectly located point of dew on the walls, mold and fungus begin to develop. Warm them better outside. Such an approach will make the walls inside the room warmer and takes the dew point to its outer face. This will help get rid of mold and fungi. If there is no possibility to heat the apartment outside, then it is allowed to insulate the end wall from the inside. At the same time, it is necessary to choose the insulation so that the dew point is in the thickness of the carrier structure.

Visual Optimal Position of the dew point

Wall insulation will help make the room warmer and get rid of dampness. The microclimate will become much more comfortable, and the tenants will be able to not worry about their health. However, it is important to warm the room correctly so that the result is as efficient as possible.

What material to choose - mineral wool or foam?

When choosing the insulation, you need to consider the features of the room. Any material must have properties:

fire resistance;
ecology (in the case of internal insulation, this factor plays a key role);
ability to absorb moisture;
high properties of thermal insulation and air permeability.

Mineral wool

Mineral wool is made from the basalt and is the most popular material in the insulation of the walls. Perfectly retains heat indoors, but easily passes air, which provides good ventilation. The air in the room is always fresh and does not stir, which also allows you to get rid of high humidity. The material is characterized by high elasticity, which is convenient when mounting. However, with time, basalt wool has a deform property, absorbing the excess moisture. Therefore, when installing, the Minvati is satisfied with the crate.

From other drawbacks, you can note the harmfulness for the respiratory organs. When using indoors, the degree of toxicity is not very high, but still the material is more suitable for the outer decoration. Another disadvantage is the increased weight.

Styrofoam

The main advantages of foam is its cost and high heat insulating capacity. The material perfectly passes air, it is lightweight and convenient for installation work. It is not toxic, because of what is perfect for interior decoration. Light weight will allow all the work independently without the attraction of builders. Particularly effective with internal insulation. Nevertheless, there are disadvantages. The foam flame is easily flammable, and is also not suitable for the insulation of wooden structures, since condensate will be formed on such surfaces.

Features of the insulation of the corner apartments of the panel house

The process of mounting panel wall fences is different for decoration of walls inside or outside the room. Consider the main differences in more detail.

Nuances of installation of thermal insulation from the inside of the room

In the panel house with internal insulation, the material needs to be laid on bare walls, which is why the procedure is better carried out in the process of overhaul. Mounting work begins with the installation of the waterproofing layer, which is most often the polyethylene film with special breathable membranes. It is best to use a solid piece of film on the entire surface of the wall. A metallic frame is installed on the waterproofing layer. After mounting the crates are installed sheets of insulating material.

An example of an internal insulation of an angle of the apartment of the Ministry of Railway

Installation from the outside of the panel

When working on the outdoor side of the room initially, all foreign objects are removed from the wall surface, their surface is thoroughly cleaned. The lamp is installed immediately to the surface of the walls. Next, two layers of waterproofing with a layer of steam insulator between them are installed. The sheets of the main insulation are installed on top. Outside, decorative facing is performed.

Features of the insulation of angular apartments of brick houses

The procedure for insulation of brick surfaces is not very different from panel. Consider the features of the outer and internal insulation of such surfaces.

Nuances of internal mounting

For internal warming of walls in brick houses, foam is most often used. Before starting assembly work, any finish is removed. The surface is carefully plastered, and after the primer is processed. It is very important to apply a smooth layer to the primer so that the formation of cracks does not begin after drying.

The insulation sheets are installed on another wet material. The fastening of the insulation is carried out on the construction glue. It is very important to pay attention to the composition components. Adhesive material should not be released toxic evaporation.

Insulation from the outside

For outdoor work, Minvata is most often used. The beginning of the work occurs according to the similar algorithm. Outside the panels are protected by an additional layer of primer to counteract the destruction of atmospheric phenomena, and a decorative finish is applied over the protective layer.

Brief overview of foam brands for insulation of walls inside

In building materials stores, you can see a fairly large range of foam brands. Consider the most common of them. Regardless of the brand, there may be two types of labels on the box: "PS" and "PSB". The first indicates that the material was made by pressing, the second is a prestickable method.

Popular brand of foam is considered C-15. This species is manufactured in a prestickable way. Due to high density, it is great for internal and outdoor work. However, it is best for insulation of corner apartments Foam brand C-25 PSB. This is a higher density material that can also be used for floating floors. The PSB C-35 Mark is distinguished by excellent resistance to extreme weather conditions. It is characterized by high fire resistance, as well as the ability to easily withstand mechanical damage. The most dense variety is C-50 PSB. This is quite expensive material that is customary to use with frequent hail and constant strong wind.

For internal insulation, only the first two options are used.

Brief overview of brands of Minvati for insulation of walls from within

There are four most popular varieties of mineral wool: P-75, P-125, PPH-200 and PJ-175. For internal works, only two first varieties are used. Wool P-75 is the easiest and features a relatively small density. P-125 is more rigid and used for interior decoration in cold climates. The last two types due to elevated density are used only for external work.

The best manufacturers of insulation are considered: isover, isorok, URSA, and Rockwool.

Alternative modern insulation

There are many non-standard alternative ways of insulation of angular apartments. They differ in the use of modern innovative materials.

Polyurene Foolder

The insulation of PPU meets all the requirements for vapor barrier, water absorption and lack of seams. Therefore, even if there is a point of dew inside the layer, it will remain "conditional", since there is no condensate condensation in the playproof materials. It turns out from the side of the room completely sealed thermal insulation layer.

Wall, insulated PPU

Keramoism

Modern building material, which is characterized by increased thermal insulation. Sold in liquid form. For the maximum effective insulation, 6 layers are placed on the wall in perpendicular to each other.

Astrak is a liquid insulation material. It can be applied to the surface with a sprayer or brush, and after drying it forms a solid and elastic substance of the porous structure. Such a insulation perfectly misses air, but effectively keeps heat inside the construction.

Liquid thermal insulation on the example of paint Mascoat

The paint of a famous American manufacturer has elevated thermal insulation properties, and also very effectively pushes moisture. Its efficiency is 5 times higher than mineral wool. 1 mm. Efficiency paints will not give up a layer of minvati floor centimeter floor. Applied to the surface of the wall as well as ordinary paint. Can be used simultaneously for decorative trim.

Polyfom

This material is made from a plastic base. Its insulation properties are slightly lower than the previous options, but the material has its advantages. Durable polyethylene film made by foaming method, from the inner side is covered with a thin layer of foil. Lens of paper are pasted on top of both sides. Externally, the material resembles wallpaper, often used as a preparatory finish before they are blending. The main disadvantage is the possibility of using dry walls only. For angle apartment may not approach, because for such premises increased humidity is characteristic.

Penophol

Penophol - Alternative insulation

Non-standard method of insulation - electric

A new, but rather effective way of insulation of walls in an angular apartment, it is considered to use the principle of a warm floor. The panels with electrical heaters are mounted indoors on the surface of the walls and are connected to the power grid. In a separate accessible location, the control unit is installed. For the correct installation, it is very important to wait for frosts, and after turning on the equipment to completely dry the walls. Only after that the additional thermal insulation layer is placed and decorative finish is performed.

This method of insulation is very effective, but has one big drawback. Cold weather will have to regularly maintain a stable temperature to prevent the formation of dampness and condensate. This will lead to additional electricity costs. The purchase of the insulating system will require considerable costs, and after will have to pay for regular operation. However, this approach allows you to create an ideal microclimate inside the corner room in cold weather.

What are the conclusions?

The procedure for insulation of the walls of the corner apartment is not considered difficult, but has many nuances. It is very important to choose high-quality insulation material, which will ensure high thermal insulation and comfortable microclimate indoor. Internal insulation is an easy way that you can do with your own hands, because of which it is more popular. Nevertheless, if in the apartment there is an increased moisture content of the walls and the formation of mold on their surface, it is better to call masters for external insulation. You can also consider using efficient and cheap alternative ways.

Most of the built panel and brick houses did not provide for the insulation of facades. Concrete and brick have high density and low thermal insulation properties. Corollary - cold walls and uncomfortable temperature. There are several ways of insulation from the inside, the main thing is to avoid the appearance of dampness.

Dew point - physics phenomena

Cold wall is not the only drawback of panel or brick houses. Often, the dampness and the mold associated with it appear on it. The best way to combat - the insulation of the wall outside (this is also the requirement of SNiP), but it is not always possible. Therefore, it is necessary to fight with a cold wall, insulating it from the inside. But there are your pitfalls.

Even if the cold wall was dry before, then with insulation, dampness may appear from the inside. And the so-called dew point will be to blame.

The dew point is the conditional border on which the water vapor temperature becomes equal to the temperature of the condensate formation. It manifests itself, naturally, in the cold season. With proper design of the house (taking into account the peculiarities of the region) it is approximately in the middle of the thickness of the facade of a homogeneous material on the density of the material.

If the insulation is insulated, the dew point shifts towards the decrease in the density (that is, to the outer surface of the wall). When insulation from the inside - it moves inside, and the condensate may appear on the surface of the main wall or inside the insulation.

And in order to assess the scale of possible damage, it suffices to say that as a result of the vital activity of one person, about 4 liters of water evaporates during the day (cooking, wet cleaning, personal hygiene, washing, etc.).

Features of the insulation of the cold wall from the inside

There are several ways capable of preventing condensate on insulated from the inside of the wall:

Creating a layer of thermal insulation material with vapor permeability is less than that of the facade material.
Warming using materials with minimal water absorption.
The use of technology of ventilated facades (including internal placement).

Liquid thermal insulation

Polyurene Foolder

The environmental friendliness of the PPU after the rejection meets the requirements for residential premises. Harmful evaporation is present only when mixing components in the process of spraying - after polymerization, the structure of the material remains stable.

They apply thermal insulation between the cage and are sewn with moisture-resistant sheet materials (GLC, OSP or plywood). In fact, it is like a large national sandwich panel.

The lack of a method is to use special equipment.

Liquid ceramics

This is a relatively young thermal insulation material, the action of which is based on the use of two principles - the creation of a thin layer with high heat transfer resistance and reflection of heat towards the radiation source.

Of course, the thin heat insulating layer cannot provide good thermal insulation - this is auxiliary, but mandatory factor. Although it gives a fairly high effect - the wall becomes a touch of much "warmer".

The main task to reduce heat loss is performed by microscopic ceramic spheres, which reflect infrared radiation.

According to the manufacturers, the effect of a layer of 1.5 mm can be compared with thermal insulation by foam 5 cm thick or mineral wool 6.5 cm.

The method of applying the same as for acrylic paint (the basis is the same). After polymerization, a dense and durable film is formed on the surface, and latex additives improve waterproofing properties.

Rolled heat insulation

Penophol

Penofol is a combination of foamed polyethylene with aluminum foil. This is a whole series of materials (including one-sided, bilateral, laminated, with adhesive layer). Moreover, it can be used both in combination with other heat-insulating materials and independently. By the way, the foofol is popular with the insulation of the bath from the inside, and there is much more couple there than in the usual residential room.

For the insulation of the cold wall, a foofol with one foil layer (one-sided) and a thickness of up to 5 mm is used.

In the case of both liquid ceramics, the effect is achieved due to the low thermal conductivity of foamed polyethylene, as well as its low vapor permeability and high reflecting foil properties (up to 97%).

But in contrast to the seamless coatings of complete sealing and preventing the appearance of the cold bridges, it is impossible to achieve. Consequently, condensate can be formed on the foil surface. Even the mandatory sealing of the joints of the adhesive aluminum foil will still leave inside the slot between the adjacent sheets.

The method of combating the formation of condensate on the traditional foil - a doomlet with a ventilated gap between the foam and external facing.

Polyfom

Another variant of foamed polyethylene, but already made in the form of peculiar wallpaper - a layer of paper is located on both sides. Polyf and designed to stick on it wallpaper.

Of course, its thermal insulation properties are not as high as the foam, but to make the cold wall to the touch warmer, they are quite enough.

In most cases, a minor thickness of the insulation does not lead to the movement of the dew point to the inner surface.

Failure of the method - insulation only dry wall.

Insulation expanded polystyrene

The polystyrene foam (or extruded polystyrene foam) is glued to the prepared and leveling wall. Both materials have very low water absorption (especially extruded polystyrene foam), therefore the formation of condensate in the insulation layer is excluded. The main danger is its appearance on the surface of a warmed wall.

Therefore, it is best to glue sheets on special hydrophobic adhesive mixtures applied over the entire surface of the sheets. And to prevent water steam penetration from the side of the room to handle seam sealants (you can also use a foam with a step or a spike-groove compound).

Finishing can be carried out in two ways:

reinforcement of the grid and applying plaster;
the covering panels on the bearing frame, fixed to the floor, ceiling and adjacent walls (false wall made of plasterboard).

Mineral wool insulation

Mineral wool does not meet the requirements for vapor permeability and water absorption for insulation from the inside. But it can be used.

The main thing is to ensure maximum protection against wet air from the side of the room and weathering of water vapor from the insulation layer. That is, perform ventilated facade, but in reverse sequence: wall, gap, vapor-permeable membrane, mineral wool, vapor barrier film, decorative facing indoors.

It is necessary to create a false wall at a distance of 2-3 cm from the main wall. And to weather vapor water from below and on top to make ventilation holes.
