How to insulate a log house from the inside. How and how to insulate a wooden house from the inside Insulation for insulating the walls of a wooden house

Our region is characterized by a long cold season. That is why the comfort of living in them largely depends on the quality of heating of the house. However, the cost of service heating devices is constantly increasing, and people are looking for options for preserving accumulated heat for the maximum amount of time. That is why many people insulate the walls of wooden houses not only from the outside, but also from the inside. Today we will tell you about doing such work with your own hands.

Advantages and features of insulating a wooden house from the inside

Insulating a wooden house is quite hard work that requires certain skills, time and effort. Therefore, before starting such work, you need to carefully weigh the pros and cons.

Used to be walls wooden house were not insulated, comfortable temperature provided in the house wood stoves. However, due to the low efficiency of such devices, fuel had to be added constantly. Thus, in addition to causing significant damage environment, people risked burning down their house.

Among the disadvantages of insulating a house from the inside, professional craftsmen, first of all, highlight an increase in the level of exposure to moisture on wood, as well as a shift in the dew point inside the wooden beams. However, this problem can be neutralized with the help of moisture protective agents.

Why is it considered better to insulate the walls inside the house:

By insulating your home not from the outside, but from the inside, you can preserve its original wooden facade of your home. Interior it will not be damaged, since the insulation layer will be hidden behind the front finish.
Unlike external insulation of walls, internal insulation can be carried out without the help of high-rise installation professionals. A tall goat and your patience will be enough here.
If the vapor barrier layer is made of a film with low permeability, then when installed outside it can disrupt the microclimate of the wood and cause it to become wet.

Thus, insulating a wooden building from the inside has its advantages and disadvantages. After reading them, you can determine the relevance of this repair in your case.

How to insulate the walls of a wooden house from the inside

How to insulate the walls of a home from the inside is a question that worries many owners of country houses. For this you can use the most different materials. It is important to choose such insulation so that it is safe for health and suits your price and quality.

There is an interesting way to insulate wooden walls inside a house. With it, tow, twine, a special compound or glue are applied between the seams of the beams. This option is used when front finishing is not expected in the house.

There is a large amount of insulation suitable for wall finishing. We invite you to familiarize yourself with the most popular options. And decide on their pros and cons.

Insulation for walls:

Mineral wool is the most environmentally friendly and safe option for insulating a house from the inside. However, this method also has disadvantages, these include: the impossibility of insulating the house without erecting a sheathing and good moisture-absorbing ability.
Polystyrene foam is also used as insulation due to its low thermal conductivity and low price. However, such insulation can emit substances hazardous to health and simply burns beautifully.
Polyurethane foam is relatively new way. To use it you need special equipment and professional help.

To insulate the walls of a house, these options are most often chosen. Each of them is attractive in its own way. However, it is best to choose mineral wool.

Before insulating your home from the inside, we suggest looking at a few tips that will allow you to do this in the most efficient way. These instructions are based on the experience of professional craftsmen.

A wooden house cannot be insulated in the first year after its construction. This time is enough for the building to settle and take on a constant size.

Wall insulation has some nuances. You will have to spend a little time studying them, but as a reward you will receive a high-quality insulated building.

Tips for insulating your home with your own hands:

The walls of a wooden structure, insulated on both sides, can rot and become damp. A well-designed ventilation system will help prevent this problem.
Even if it seems to you that the wall is freezing in only one place, you still need to insulate all the walls in the house at once.
The places behind the batteries must be insulated with foil material. This will ensure the flow more heat into the room.
You need to leave some space between the insulation and the wall. This way, the thermal insulation of the walls will not affect their humidity.
Before starting insulation work, treat the walls with a moisture-repellent compound. This way you can avoid side effects internal insulation.

The walls of a building must be insulated from the inside correctly. Otherwise, you will not only be unable to maintain heat, but will also cause it to be lost more quickly.

Insulation of wooden walls from the inside

Insulation of a building made of wood occurs in several stages. The progress of work with different insulation will look different. Since mineral wool is currently considered the most common insulation material, we will tell you how to insulate the walls of a house with your own hands.

Stages of insulating the walls of a house with your own hands:

The first thing you need to do is clean wooden walls from pollution. Old layer finishing, if any, is removed. A bare and clean wall is treated with antiseptics.
Next you need to caulk the walls. If this new house, then caulking occurs a year after construction, if they lived in it, then after three. Caulking involves pushing material, such as jute, into the cracks between the logs. The work is done using a thin chisel.
Moisture insulation is being installed. To do this, take a vapor barrier sheet and apply it with the rough side to the logs, after which it is nailed construction stapler. The joints between sections of such fabric should overlap by 15 cm and should not be taped.
Now it's time to do the sheathing. To do this, you need to take a wooden beam 5x5 cm, and make a lath out of it, arranging the elements in increments of 50-60 centimeters.
Layers of mineral wool are inserted into the resulting lathing. They are attached using construction stapler. After installing mineral wool, it must be covered with a layer of waterproofing material.
At the last stage, the structure is covered with plasterboard. After this, the front finishing occurs.

The same principle applies to warming the year. Of course, we have presented a brief scheme for insulating a house, but in principle, all the necessary steps can be completed using it.

Comfortable temperature regime home is one of important conditions for the health of its inhabitants. To ensure a normal environment in the room, insulation work is carried out. Insulation is necessary stage construction of a house, it is better to do it at this stage, but it can be done later.

What you need to know about insulating the walls of a wooden house inside

Owners of private wooden houses They know how important it is to insulate a house. How comfortable living there will be depends on this. No matter what building material the building is built from, timber or logs, it needs insulation, especially considering how severe frosts there are in our country.

A professional does not need to talk about materials and technologies - he already knows everything, but what should an amateur pay attention to if he wants to create the inside of a wooden house with his own hands?

There are two main technologies for insulating the walls of a house - external insulation and internal insulation. Each has its own characteristics, pros and cons.

For external insulation, the insulation material is located outside, which allows you to preserve the building’s façade from adverse natural factors. In addition, space is saved.

Insulation from the inside is chosen if, for example, it is impossible to “touch” the facade or for some reason it is impossible to build a wooden house.

Before you start insulating timber house or insulating a log house, you need to determine how to arrange waterproofing so that there is no condensation.

When the insulation is located inside, the outer wall freezes and condensation forms. So think about waterproofing first. Can, for example, be used when attaching insulation to a wall plastic film– it is suitable in many cases.

How to insulate a wooden house

The modern construction market provides a lot. Among them, the most popular are those that are both not very expensive and at the same time effective. Therefore, it has become possible to insulate walls inside a wooden house even for an inexperienced person.

Penoplex, or expanded polystyrene white, consists of air and polystyrene foam. It is produced in the form of slabs of different thicknesses and sizes. Easy to use, making it in demand in the market building materials.

Expanded polystyrene characteristics:

Low thermal conductivity;
High noise absorption;
Does not create conditions for the development of a humid environment;
Long service life;
Doesn't highlight harmful substances in operation;
Resistant to temperature changes;
Light weight, which is convenient for transportation and installation;
Does not ignite;
Does not create a comfortable environment for the growth of fungi and mold;
It's inexpensive.

The technology for insulating a house with penoplex is as follows:

First you need to prepare the wall, clean it of dirt and dust; you can use a regular broom for this purpose. If there are cracks, they should be repaired using putty.
The surface is primed with acrylic - this prevents the formation of fungal colonies.
When the primer is dry, stick it on polystyrene foam boards. The glue is applied to the wall and to the slab, after which the slab must be pressed against the wall.
Work starts from the bottom, the slabs are glued end to end in a checkerboard pattern. The seams must be treated using polyurethane foam.
When the glue dries, each slab must be attached for greater fixation using dowels in the corners and in the center.
The top is covered with a membrane film or polyethylene for waterproofing, and it is glued together with tape at the joints.

Next is the reinforcing mesh.
After this, you can start decorating.

It has several varieties, among which the most popular is stone wool, which is produced by melting volcanic rocks. Compared to glass wool, it has more advantages.

Basalt insulation characteristics:

Safety during installation;
Good insulation indicator;
High noise absorption;
High vapor permeability;
Does not emit toxic substances;
Does not ignite;
Resistant to temperature changes;
Does not rot, does not mold;
It lasts a long time.

The technology for internal insulation of house walls with mineral wool is as follows.

The wall is cleaned of dirt. All cracks are treated with putty. If there is mold or fungi, the area should be thoroughly cleaned, washed, dried and treated with antifungal agents.

Mounts on the wall.

The sheathing is made of vertical wooden beams. In this case, it is important that the pitch of the sheathing corresponds to the width of the mineral wool roll in order to tightly attach the insulation to the wall.
A mineral wool slab is mounted end-to-end between the sheathing beams. The seams are sealed with adhesive tape.

Next, the membrane vapor-waterproofing film is stretched. It needs to be glued at the joints and ensure that the seal is not broken.
This layer is fixed to the sheathing with wooden planks.
The interior walls of the house are being finished.

Foil insulation

This is a high-tech material coated with foil, which, while not being a heat insulator itself, effectively reflects heat, directing it back into the house. There are quite a lot of varieties: penofol, with a self-adhesive coating, single-sided and double-sided, isover, etc.

The technology for insulating a log house from the inside using material with foil is briefly as follows.

The wall surface is cleaned of dirt and dust. All cracks and crevices must be filled using putty.
A wooden sheathing of beams is attached to the wall, the pitch of which corresponds to the width of the roll of this material.

The foil coating is placed end-to-end between the sheathing bars; it is necessary to ensure that the metallized layer is directed into the building. The joints must be sealed with aluminized adhesive tape.

Unlike other insulation options, the use of foil material allows you to avoid installing a waterproofing film. Therefore, after installing it, you can start interior decoration walls of the house.

Differences in methods of insulating the walls of a house

In construction, both methods of thermal insulation are used - external insulation and internal insulation. However, insulating a wooden house from the inside has more disadvantages and is performed more often if insulation from the outside cannot be done for various reasons. Installing insulation cannot be called a very complicated process, but if you have basic construction skills, it can be completed quite quickly.

But for a person who does not have professional knowledge, experience and skills, it will be difficult at first to understand the intricacies of the work. Of course, it will take time to study all the nuances of insulating a wooden house from the inside with your own hands. But with what pleasure all family members will return to a cozy and comfortable home!

Every person dreams of a warm home, so that even in the most severe frosts it would be comfortable to stay indoors. Therefore, the first question that faces the owners of their home is how to insulate the walls from the outside on their own. Especially it concerns wooden buildings. In this article we will provide instructions according to which the walls of frame and timber houses are thermally insulated from the outside. And for more clear example you can watch the video.

There is a huge variety of thermal insulation materials. Let us dwell on the choice of insulation for wooden houses, which are widely used by consumers.

Insulating a wooden house will help save the wood from destruction

Stone wool in slabs. This material is easy to cut even with a regular knife. Due to their light weight, the slabs are easy to transport even in a passenger car, especially if you need to insulate small area. During installation stone wool laid in the gap between the frame posts, and then insulated with vapor barrier material on the inside and waterproofing material on the outside.

Attention! When transporting or installing, do not compress or compact the mats under any circumstances.

Ecowool. This is an environmentally friendly insulation material based on cellulose fibers. Available in slightly compressed packaging. There are two ways to insulate with this material:

dry. To do this, the packaging with glass wool is opened, the material is kneaded and compacted into the walls. The disadvantage of this method is that over time the fibers can shrink, which will lead to heat loss. However, some manufacturers guarantee that this material will not settle for 10-20 years.
wet. Ecowool is sprayed onto the walls and adheres to the building frame, so the material does not settle.

Insulation of a wooden house from the outside

Styrofoam. One of the most budget types insulation. This material does not absorb moisture, so it is not necessary to cover it with a moisture-proof membrane. However, when working with polystyrene foam, you need to be as careful as possible, as it can crumble and break.

Attention! As insulation, you need to purchase unpressed sheets of polystyrene foam.

Polyurethane foam. It is sold in the form of two-component substances that begin to foam when applied to walls when exposed to air. In operation, this material is similar to polyurethane foam. They fill the voids in the wall, and cut off the excess. The result is a monolithic layer of insulation that completely eliminates heat loss. Polyurethane foam has moisture-repellent properties.

Insulation of a timber house with polyurethane foam

Natural insulation. These include slabs made of sawdust or a mixture of clay and straw. Such materials are environmentally friendly and inexpensive, but their main disadvantage is the complexity of manufacturing. Flax fiber is also a natural insulation material. It has antiseptic properties, preventing the formation of fungus and mold. It is easy to cut, install, does not cause allergies and is moisture resistant.

What is the best way to insulate walls?

The key to quality repairs is a well-thought-out work plan. Therefore, it is worth considering in advance how you will insulate the walls: from the inside or from the outside. Internal insulation is rarely used, because because of it, the size of the rooms is significantly reduced. In addition, experts do not recommend insulating wooden houses in this way, because moisture will penetrate into the wood, from the street side. Because of this, mold and mildew may appear inside the structure, and the wood itself will begin to rot. In addition, it is necessary to buy a material that will match the properties of wood. Flax fiber, soft fiberboard, basalt and fiberglass materials are suitable for this.

Insulating a house with mineral wool

With the external method of thermal insulation, a uniform layer of insulation is formed for the free escape of vapors. The insulation is less dense than wood, which causes steam to escape through the ventilation gap. External thermal insulation method - perfect option for those who want to insulate old houses made of timber, which have lost their “marketable appearance” over time, after covering they will look like new. However, if you insulate the walls incorrectly, the wood will begin to deteriorate, and under the layer exterior finishing, you will not be able to control the condition of the wood.

Insulating the walls of a frame house with mineral wool

Thermal insulation frame house It starts with waterproofing. For this you can use glassine - cheap, but efficient material. It is cut into strips and stapled to the frame of the house, in increments of no more than 12 cm. Glassine sheets are glued with an overlap of up to 10 cm to protect the insulation from condensation.

Advice! If the frame of the house is covered with siding, then a distance of 30-50 mm should remain between it and the insulated facade so that moisture does not linger in the frame.

Then we lay a layer of insulation. Mineral wool is an excellent option for wall insulation. It does not cause allergic reactions, has low flammability and high thermal conductivity; such slabs can be easily cut with a construction knife. The installation process is simple, first we measure the distances between the posts and add 5 cm on each side for allowances. We cut out the sheets of the required size and lay them on the waterproofing. We close the joints between the frame and the insulation with a strip of mineral wool 3-4 cm wide.

Mineral wool

We lay a layer of vapor barrier on top, for this we use penophenol. It needs to be shot to the building frame using a construction stapler. Penophenol is laid horizontally, leaving 5 cm joints with the foil part facing out. After this we cover the walls of the house edged boards or siding.

Insulating the walls of a frame house with foam plastic

In order to secure the foam to the wall, we first install vertical canopies made of cord. Then glue is applied to the foam sheets, along the edges and at five points inside, and fixed to the wall. This is how all the insulation is laid. Next you need to seal the cracks with foam. For additional strength, we fix the sheets with plastic dowels.

Attention! Polystyrene foam does not absorb moisture, so additional insulation is not needed in this case.

The outside walls need to be plastered, and before that you need to install reinforced mesh. Putty will help protect the structure from influence external factors, but it should be applied in two layers. After drying, the surface can be applied finishing layer decorative plaster.

Insulating the walls of a timber house

External insulation of houses made of timber should be done with slab materials; they are more rigid and do not shrink over time. If you prefer basalt or fiberglass insulation, then you need to choose the right thickness. If the house is made of 15 cm timber, then the thickness of the heat insulator is 10 cm, and if the timber is 20 cm, then you can take a thinner material - 5 cm.

To begin with, the surface of the house is coated with waterproof mastic. Then a vertical wooden frame is installed, which must be coated with an antiseptic to prevent rotting. Then they attach it to basalt wool using self-tapping screws or umbrella dowels, 4-6 fasteners per 1 sq.m of insulation. A diffusion membrane is laid on top as a waterproofing agent. Above wooden frame we nail slats 5 cm thick, which will create a ventilation gap to remove moisture. Then we nail the profiles to the slats and install the siding, starting from the bottom, checking the horizontal installation with a level.

Scheme: house insulation

Thus, the choice of insulation depends on your personal preferences. And deciding whether to do internal or external thermal insulation depends on how it will be done finishing external walls. Well, if you want to ensure that even the most severe frosts do not bring you inconvenience, you can insulate the walls both inside and outside.

Insulating a house with mineral wool: video

Insulation of a wooden house from the inside is used much less frequently than insulation from the outside. The reasons for the unpopularity of internal insulation are the following: although insignificant, there is a reduction in the living space of the house; you can easily spoil the microclimate inside if the procedure is carried out ineptly, and this will entail unnecessary air humidity.

When insulating floors in a wooden house, an air gap of at least 50 millimeters must be provided between the insulation and the vapor barrier.

Nevertheless, if a decision is made, then the work must be carried out, observing the entire sequence of work and technology.
The procedure itself differs little from the thermal insulation of a wooden house from the street.

The reasons for the appearance of cold in a wooden house are considered to be:
the appearance of gaps between the bars due to shrinkage, incorrect sealing, etc.;

insufficient thickness of the heat insulator from the street;

incorrect installation.

Varieties of modern materials that act as insulation

Scheme of insulation of wooden walls.

Types of insulation:
basalt mineral wool, produced in sheets of various sizes or in rolls;

glass wool - often serves as floor insulation;

expanded polystyrene - universal insulation for all surfaces;

isoplats - wood fiber or linen boards 12-25 mm thick for floors, walls and ceilings.

Isoplat – universal thermal insulation material for internal wall insulation. It is lightweight and reliable in laying slabs, which are inserted between the sheathing frame and secured with screws. Its slabs are covered with clapboard, painted or covered with wallpaper.

If expanded polystyrene is chosen as the insulation of a log house from the inside, then it is important to remember that it itself is a self-sufficient waterproofing agent. There is no need to use other means of waterproofing walls together with expanded polystyrene. However, rodents love the material. Therefore, in order to avoid the appearance of mice in the house, it is preferable to insulate wooden walls from the inside with mineral wool or isoplate, and floorboards with glass wool or isoplate.

The technology involves performing several operations

Insulation diagram inside a wooden house.

From inside:
Preparing the wall surface.

Caulking cracks.

Formation of vapor barrier.

Installation of sheathing on load-bearing wall surfaces.

Installation of insulation and work on its sealing.

Creation of a ventilation system.

Decorating the house inside.

Preparatory procedures

Before starting to insulate the house from the inside, the first step is to superficially clean the load-bearing walls from dust. Then the wood is carefully treated with an anti-insect emulsion liquid and another anti-insect liquid, which also makes the tree more resistant to burning.

It is important to pay attention to surface wiring and those that are hidden in special casings. The wiring is completely separated from the walls.

Caulking cracks

Scheme for insulating the foundation of a wooden house.

After cleaning and fire protection from the inside, they begin to caulk the cracks. If we talk about caulking a house made of timber in general, then in the future they will perform secondary caulking. Only it will be different in time for a house made of timber, in which no one lived, and for a house in which they began to live immediately after construction. In the first case, they wait 1 year, and in the second, they caulk the cracks after two to three years. This is explained by the unequal degree of shrinkage in these two cases.

The cracks are caulked using mainly jute fiber. Using a special thin chisel, fill the cracks with jute, if any. Sometimes the cracks are quite large. Then it is advisable to use tape tow, rolled into a small roller. The gap is filled both inside and outside with jute until the fiber can no longer fit. Small hanging or protruding pieces are left as is.

Formation of a vapor barrier

After all the thermal insulation work, the wooden surface of the house from the inside, made of beams, will be between two layers of thermal insulation (internal and external). This will lead to an inevitable increase in humidity levels, creating a greenhouse effect, as the house will stop breathing.

Humidity can only be removed by creating forced ventilation. The main nuance here - to prevent dampness of the wood and its subsequent decay.

Scheme of floor structures in a wooden house.

To prevent this, a hydro- and vapor barrier film is attached to the entire surface of the insulated wall before installing the heat insulator. The corrugated side of the film is placed against the surface of the beams. This placement of the film coating will protect the wood from moisture and allow the wood to breathe somewhat, removing excess moisture.

Installation of lathing on load-bearing wall surfaces

The lathing, the purpose of which is to hold mineral wool, is made of wooden blocks. The lathing is made from metal profiles only if they plan to cover it with plasterboard of the GKLV brand, where “B” means “moisture resistant”.

To form correct and even corners, corner posts are knocked together in advance. Measure the height of the room and cut it wooden blocks(100x50 mm section).

After this, a block of the same length is cut, but with a cross-section of 50x50 mm. The latter is attached to the edge of a 50x100 mm beam using self-tapping screws in such a way that a stand in the shape of the letter “L” is obtained. One stand is made for each corner of the room. They are fixed directly in the corner using self-tapping screws. The vertical position is controlled using a level.

After fixing the racks at the corners to the surface of the wall located between them, vertical bars with a cross section of 50x50 mm are mounted in increments of 50-60 cm. All bars are treated with a liquid that protects against rotting and burning.

Installation of insulation and sealing work

Scheme for insulating a subfloor in a wooden house.

Having installed the sheathing, they begin to lay mineral wool. To begin with, the roll is unrolled and a strip of mineral wool is cut to height. The width of the strip should be 2 cm greater than the vertical gap between the bars.

Then a piece of mineral wool is placed between the bars, fixed to the wall surface using anchors with large round caps. This type of work requires the presence of a partner who will help hold or secure the cotton wool.

After filling the space between the battens with mineral wool in one layer, a second layer of insulation is attached on top of the bars. A layer of hydrofilm is attached to the cotton wool, applied with corrugation to the insulation. In addition to the function of protecting against moisture, the film will serve another purpose here - to prevent small particles of mineral wool from entering the space of a wooden house.

Creation of a ventilation system

As mentioned above, after work on the internal insulation of a log house, the humidity inside it will increase significantly.

Scheme of vapor barrier for the walls of a wooden house.

To ensure a normal microclimate, forced ventilation must be provided in all rooms.

It is unacceptable to install direct hoods outside. It is necessary to create an air duct system connected in one chain. Any axial fan average and even low power can act as a supercharger. IN winter period it will be enough to include homemade device ventilation for half an hour a day to create optimal humidity indoors.

Wall decoration

After attaching the second layer vapor barrier film They are starting to finish the walls. The film is pinned to the bars using a stapler and staples, which will make it possible to attach 30x40 mm slats to the film over the staples. Such slats are commercially available.

Having mounted such a block, sheathing is carried out on it wooden clapboard with a pronounced texture. Insulating the house and then covering it with clapboard will allow you not to lose the original appearance of the wooden interior. Instead of lining, you can install a plank horizontally, which will also be quite a good decision, since this material looks like a small beam.

Correctly performed insulation of a wooden house can significantly save on heating, improve the microclimate in the house, and also extend the service life of the log house. When the question arises about thermal insulation of the walls of a wooden house, the first and most important point is the choice of insulation method - from the inside or outside. Most home owners choose external insulation, and this choice is absolutely correct - external insulation of a wooden house is more effective.

At internal insulation Not only does the usable area of the premises decrease, but the dew point also shifts inside the log house. Only the inner space, the log house itself constantly experiences changes in humidity and temperature, freezes in winter and rots in summer. The greatest destruction of the log house occurs with inside, covered with insulation.

External insulation protects not only the room, but also the log house itself from freezing. The dew point shifts outward and condensation occurs outside wooden structures, under a ventilated facade, where moisture dries quickly.

Materials for insulating a wooden house

As insulation for wooden houses, mats made of stone or mineral wool are most in demand. It is not recommended to use polystyrene foam for insulating wooden structures, since it does not have vapor permeability and does not remove moisture vapor from the surface of the log house. Stone or mineral wool mats come in various thicknesses and densities. The denser the insulation, the easier it is to install and the longer it retains its properties. performance characteristics. Soft and loose mats often slide down and fall apart, forming dust that is harmful to health. Therefore, you should not skimp on high-quality insulation. Other advantages of stone or mineral wool include its non-flammability and unpopularity with rodents, unlike polystyrene foam.

In addition to the insulation, two layers of film are required: one is waterproofing and protects the frame from moisture penetration. It is placed on the protected wooden surface. This film must be vapor permeable and remove moisture from the log house through the insulation into the external environment. The second is wind and water protection; it is mounted on top of the thermal insulation. The purpose of this layer is to protect the insulation from moisture coming from external environment. Waterproofing mineral insulation mandatory, since when wetted it loses its thermal insulation properties.

From the outside, the insulation is covered with any facing material with mandatory arrangement ventilation gap. This cladding is called a ventilated facade. Thanks to air circulation between the cladding and the walls, the formation of fungus and mold is eliminated, moisture is successfully removed from the insulation, and all conditions are created for the long service life of the log house and the entire building.

Technology for insulating a wooden house from the outside

The walls of a log or timber house are treated with an antiseptic in two layers, focusing Special attention lower crown and corners. The ends of the logs are impregnated with antiseptic especially carefully, since they are most susceptible to rotting. It is best to carry out processing in warm, dry weather. After treatment, the walls are dried for 1-2 days.
A waterproofing film with a vapor-permeable coating is secured to the walls using staples and staples. This film has different coating sides: the glossy one should be facing the insulation, and the porous one, capable of absorbing and removing moisture from the log house, should be facing the wall. The joints of the film are overlapped and taped with special mounting tape. A vertical sheathing made of a bar is attached to the film; the thickness of the bar must correspond to the thickness of the insulation. The sheathing pitch is chosen 3-5 cm less than the width of the insulation mats. Layed flat, they will hold perfectly without additional fastening.
Place on the film between the bars thermal insulation mats, slightly squeezing them. If necessary, mats are cut with a regular knife. If the mats are not hard enough and do not stick well inside the frame, you can perform temporary hemming by fixing them with slats. The mats are finally secured using anchor nails. If it is necessary to lay several layers of thermal insulation, the subsequent layer of mats is laid with offset seams so that the upper mats overlap the joints of the lower ones. All work on laying mineral wool mats must be carried out wearing protective gloves and a respirator.
A waterproof membrane film is attached to the brackets on top of the insulation. The waterproof surface must face outward. The joints are overlapped and taped.
Installing a hydro-windproof membrane film over the insulation using a stapler
A ventilated frame must be installed on top of the film. It is also made from bars, providing a distance between the layer of insulation covered with wind protection and decorative facade at least 5 cm. The bars are attached to the lower frame with self-tapping screws, and if the walls are not level enough, then use perforated hangers for the profile, allowing you to adjust the distance to the frame. Under metal siding or corrugated sheeting, you can use a plasterboard profile instead of a block.
The sheathing is fastened using the technology recommended by the manufacturer. For cladding, you can use vinyl siding, metal profiles, block house or imitation timber. When covering, make sure that there are no gaps through which moisture can penetrate into the facade.

An additional measure to protect a wooden house is insulation of the foundation and basement. It can be produced using or, as well as by spraying polyurethane foam. A ventilated façade or cladding is also mounted on top of the insulation layer. decorative stone or brick.
