The procedure for insulating a house from a bar: what you need to know about facade work. The correct method of external insulation of a house made of timber Correctly insulate a timber house from the outside and how

When arranging their own private house, many people are wondering how to insulate a house from a bar from the outside. This is due to the fact that most modern buildings are made on the basis of high-quality wood, but their thermal insulation properties leave much to be desired. To ensure a good microclimate in a log house, you need to increase the thickness of the walls, but not everyone is ready to sacrifice aesthetic appeal for the sake of warmth.

Features of warming a log house from the outside

And there is no point in taking such drastic measures. If you apply the right methods of warming timber structures, the issue of effective thermal insulation will be resolved in a short time. You can warm the room both outside and inside. Today we will deal with the topic: “How to insulate a house from a bar outside and how to do such a procedure with your own hands”.

Fortunately, these days there is a wide variety of instructional videos and additional material, with the help of which the complex of upcoming events will become simpler and faster. If you have the desire and time, you can insulate your room in at its best. So, first things first.

Do-it-yourself insulation of a log house from the outside

Many wooden houses do not have a sufficiently large wall thickness, therefore, it is difficult for them to endure the harsh Russian winters with severe frosts and strong winds. Even high-quality sealing of all cracks in the log house is unable to improve the thermal insulation properties of the building.

Therefore, in order for the house not to freeze under the influence of extremely low temperatures and to maintain optimal temperature conditions, it is necessary to insulate it from the outside. Arrange good system thermal insulation is not as difficult as it seems at first glance. Today you can find a wide range of different thermal insulation solutions built using very simple technologies, which allows you to carry out a number of home insulation activities without special skills or abilities.

And to simplify the task ahead, you can watch a lot of training videos with a detailed explanation of each step.

Proper external insulation of a log house involves the use different materials. The main thing is that they meet the following requirements:

• had excellent fire resistance and were not exposed to high temperatures;
• have low thermal conductivity;
• were environmentally friendly and did not emit toxic substances during operation;
• had good thermal insulation performance;
• did not accumulate moisture;
• passed from the room various escaping fumes;
• differed in good noise-insulating indicators.

As for external insulation, this method has many advantages, namely:

• the possibility of a quick transformation or renovation of the house;
• reduction of fuel costs due to improved thermal insulation;
• providing effective protection against any external factors: noise, moisture, dampness;
• significant savings in free space;

If you follow some instructions, study photos and videos from detailed guide for insulation, the upcoming procedure will be completed much faster and more productively than expected. Experienced experts advise paying attention to such subtleties:

• when installing insulation, you can not leave this material on the street under the open sky. If it is exposed to rain, it is likely that its heat-shielding performance will deteriorate greatly. Therefore, store the insulation in a warm, well-ventilated and dry place;
• laying the bars of a horizontal crate with a step less than the width of the insulation by 15 millimeters, you can refuse to use fasteners;
• when laying the insulation, be sure to follow the safety rules and use personal protective equipment. These include a respirator, gloves, goggles.

Proper installation of insulation in houses made of glued laminated timber involves the use of three main methods:

1. arrangement of a hinged ventilated facade;
2. the use of foam as a heater;
3. spraying walls with polyurethane, for which it is necessary to use special equipment.

According to experts, it is most expedient to apply hinged ventilated facade method, because it has many advantages, including:

What materials will be the most effective in insulating the walls of houses from glued laminated timber

Today, there are many excellent heaters with high thermal insulation properties and durable construction. Among the most popular are:

• fiberglass;
• mineral wool;
• basalt mats;
• expanded polystyrene and others.

Each of the aforementioned heaters has its pros and cons. They also differ in the method and features of installation, so before you opt for specific proposal, you should make sure that you can install it yourself without the help of a specialist. The main thing is that the selected material meets all the requirements of quality and safety.

A good insulation for the walls of a house made of glued laminated timber should have:

1. excellent thermal insulation;
2. incombustibility;
3. moisture resistance;
4. the ability to effectively prevent heat transfer between the inside of the room and the outside;
5. environmental safety.

How to insulate a house from a bar. How to properly insulate

Insulation of a house from a bar - process is painstaking and responsible. But if you take into account all the "pitfalls" in advance, weigh the "pros" and "cons" of each heater, the upcoming procedure will be performed without the slightest difficulty.

It should be noted that today the most popular material for insulating walls made of glued laminated timber from the outside is mineral wool. Its plates have small dimensions, due to which the additional load on the structural parts of the room is significantly reduced. In addition, this option is very cheap, perfectly retains heat indoors and prevents the penetration of atmospheric moisture inside. Also, mineral wool is famous for its incombustibility, and due to its softness and elasticity, it quickly acquires the necessary shape and does not form bridges during installation, while remaining resistant to thermal deformations.

Installation of insulation can be carried out under a block house or with the help of plastic siding, which is used to sheathe the walls of the house from the outside. Complex installation work on warming the house can be divided into several separate stages. Let's talk about each of them in more detail.

vapor barrier

Before proceeding with the installation of insulation, it is necessary to provide an effective vapor barrier system. On the this stage you can use aluminum foil, vapor barrier film or roofing felt. The procedure allows to ensure good ventilation properties of the facade under the film and involves the installation of vertical rails 2.5 centimeters thick at a distance of one meter from one another. After that, a vapor barrier layer is installed on the underlying rails on the entire surface. Holes with a diameter of 20 millimeters are made between the base rails for successful ventilation..

The presence of such a system will prevent the penetration of atmospheric moisture inside and the accumulation of internal moisture under the film, which can cause rotting of the wooden wall. To fix such a vapor barrier, nails or staples are used, and the attachment points are sealed with adhesive tape to protect them from water penetration.

Mounting the frame for effective thermal insulation. Laying thermal insulation

In order for the final result from the insulation of the walls of a timber house to be as successful as possible, pay attention to such a mandatory procedure as mounting the frame. As a frame, you can use high-quality boards 100 mm wide and 40-50 mm thick, which are mounted on the wall vertically on the rib. The distance between the boards should not be less than the width of the insulation.

The beam is attached to the facade with self-tapping screws. During installation, it is necessary to control the position of the beam using a level or plumb line. If the crate is uneven, the installation of the cladding at the final stage will be ineffective.

To prevent the appearance of gaps between the boards, mineral wool is installed very tightly. Material with a thickness of 50 millimeters is laid in two layers, using semi-rigid, elastic plates with a density of 80-120 kilograms per cubic meter. In this case, the plates hold perfectly between the frame boards and do not slip during operation.

After completing the installation of thermal insulation, you should proceed to laying a waterproofing film, which is designed to pass steam and retain water. The film is laid on a heat-insulating layer and nailed with staples or nails from the frame. When joining the film, it is necessary to leave at least 5-10 centimeters of overlap, and cover the formed joints with self-adhesive tape.

Laying the second layer of the frame

Stuffed on the frame of the heat-insulating layer slats 50 millimeters wide and up to 3 centimeters thick. This step allows free circulation of air between the cladding and the vapor barrier to prevent the formation of condensate that appears on the waterproofing layer. The resulting space is covered with a dense metal mesh to prevent the penetration of insects and rodents.

Concerning outer skin, in most cases, it performs only a decorative role, so what material will be used for cladding is up to you. The main thing is that it meets your design requirements and complements the overall style concept. As a facing material, you can use wooden lining, and plastic siding or any other material.

Ready-made heaters

It's no secret that in recent times on the market you can find a lot of ready-made heaters for effective thermal insulation of walls made of glued laminated timber. They are manufactured according to advanced standards and high technologies. The most popular of them is the famous Penoplex”, which is produced by a Russian company. The material is offered in the form of soft and high-quality thermal insulation boards, which are an effective form of foamed extruded polystyrene foam created using a special technology.

Such panels are famous for their high resistance to external influences, durability and long service life. They are able to prevent the penetration of moisture, dampness, bacteria, mold and other microorganisms into the premises, providing the right microclimate and comfortable conditions residence. Now Penoplex is a new word in the world of domestically produced heat-insulating structures.

The comfort and coziness of the future home depends on how the house is insulated. For the insulation of walls made of timber today, the following materials are used:

Timber house insulation technology

Answering the question "How to properly insulate a house from a bar", it should be noted that wall insulation must be started already in the process of building a log house. For this purpose, the grooves between the beams are filled with a special insulation. And the main work on insulation is carried out a year after the completion of construction. The reason for this is that wood Construction Materials subject to shrinkage and shrinkage.

There are two ways to insulate walls. This is the installation of insulation from the outside and from the inside. Often in construction both options are used. This combination is relevant in places with harsh climatic conditions.

Wall insulation from the outside

Experts believe that the best option for insulating a house from a bar is the method of creating a ventilated facade. This method allows you to get an air gap, which turns out to be a wonderful heat insulator, besides, it allows the tree to "breathe".

Insulation of the walls of the house from a bar from the outside is carried out in the following order:

1. First, the log house must be checked for the presence of gaps between the beams, which may appear in the process of shrinkage and shrinkage. If such defects are found, they should be caulked with a sealant (see Tool for caulking a log house).

2. The next step will be the treatment of the walls with antiseptic and fire-fighting substances. This will prevent the appearance of fungus on the walls in the future. The process is described in detail in the article Processing wood from decay.

3. Then a layer of vapor barrier is laid (see Which side to lay the vapor barrier). For this you can use:

• ruberoid,
• aluminum foil
• polyethylene,
• vapor barrier.

Layers of vapor barrier are overlapped, and the joints between them are glued with adhesive tape.

4. Next, you can proceed with the installation of the frame from the boards. For this, boards with a thickness of 50 mm are selected, and a width of a little more than 100 mm. The boards are mounted on the wall at a distance from each other slightly less than the width of the insulation, so that the latter fits snugly between them and no gaps form.

5. The next step will be the installation of insulation. This element is laid from the bottom up between the frame boards, and then fixed with dowels. For a house made of timber, glass wool or mineral wool is perfect. You can also use foam. But it is important to remember that you should not press the insulation against the wall too much. This may destroy its properties.

6. The next step will be the laying of a waterproofing layer. In this case, a polyethylene film with high vapor permeability or roofing material is used. This layer is fastened with a stapler or nails over the insulation. It is designed to protect the house from the action of moisture and blowing out with a stream of air circulating in the air gap.

7. The final stage of wall insulation is the installation of outer skin on the supporting frame. As a material here, you can use lining, siding, facade panels or a blockhouse (see Installing a blockhouse with your own hands). Without fail, a gap of 2-4 cm must remain between the waterproofing and the sheathing.

Thermal insulation from the inside

Professional builders strongly recommend to refrain from internal insulation timber house walls. This is due to the fact that as a result of such insulation, the dew point (a conditional plane between the outer space and the inner room, where the temperature crosses the mark of zero degrees Celsius) moves from the outer insulation layer inside the timber. As a result, the wood becomes wetter, loses its characteristics faster and its service life is significantly reduced.

The main requirement that applies to insulation used inside the house is its fire safety. As such a material, fiberglass or mineral wool can be used. Wall insulation from the inside is carried out in the following order:

1. The first step is to check for gaps between the beams. If necessary, they are sealed with jute fiber or tow.
2. Next, a vapor barrier film is stretched on the wall. It is strengthened with a construction stapler.
3. A wooden frame is attached on top of the film, and insulation boards are placed end-to-end between the frame beams. For fastening, you can use self-tapping screws, nails, etc.
4. At the next stage, a layer of finishing material is mounted on the frame. Ideal for a log house wooden lining, but you can also use drywall sheets, plywood or OSB boards.

Insulation of the house, made in accordance with all the rules, will make the home truly cozy and warm. In addition, it is quite possible to do this work with your own hands, even in the absence of special skills.

Tips on how best to insulate a house from a bar from the outside and from the inside. Watch the video lesson.

As you know, a wooden house has many advantages. Firstly, wood is the most environmentally friendly material that creates a unique atmosphere of warmth and comfort in the house.

Secondly, a wooden house will cost much less than a brick or foam concrete building.

A house made of timber can stand for decades, but over time, cracks form between the logs, the tree dries out, and the walls become more ventilated, drafts appear, and warm air begins to come out.

And here, many owners naturally wonder how to insulate a timber house so that it is cozy and serves for a long time.

It is possible to insulate the structure both from the outside and from the inside. But insulation from the outside will be a rather complicated process, since it must be invisible or very aesthetic so as not to spoil appearance Houses. But warming from the inside is a simpler task.

Insulation of a house from a bar from the inside

Before performing insulation, it is necessary to check the quality of the wall surfaces. The tree tends to dry out during the shrinkage of the house, and therefore the existing cracks or chips must be carefully repaired.

If such defects are not repaired, then the insulation of the walls will not give any effect. Slots can be sealed with jute fiber, and especially large ones with tape tow, which must be rolled into a roller. The walls must be treated with an antiseptic composition before starting work.

The first stage of insulation is vapor barrier. It is absolutely necessary, because the condensate on the walls of the log house, which appears due to temperature changes, can severely damage the building.

High-quality vapor barrier, a film that is pasted over the whole house, prevents the appearance of mold and rotting of the log house and can significantly extend the life of the building.

After leveling the walls and laying a layer of vapor barrier on bearing walls ah, a crate is made on which the insulation is laid. It must be carefully sealed. After creating a competent ventilation system interior finishing is being done.

Insulation materials must be of the highest quality. The main selection criteria are safety for health, ease of installation, incombustibility, durability.

When a crate is created from wooden bars, mats of mineral wool, glass wool or other insulation are placed in it with a margin of 1-2 cm.

When the insulation is installed and fixed, you can strengthen the thermal insulation with another layer of vapor barrier.

After that, sheathing is done. Wooden lining is usually chosen as a finishing material, which allows not to disturb the original interior of a log house.

It is necessary to insulate not only the walls, but also the floor, as this is the coldest place in the house.

Insulation can be performed both with the same mineral wool, and, for example, with foam plastic, foam polyethylene or expanded polystyrene.

You can also use cheaper natural materials: expanded clay or sawdust. If there is already a coating on the floor, then it must be dismantled.

After dismantling, they fall asleep and level the "cushion" of gravel. Then the rough concrete floor is poured.

After it dries, a waterproofing layer is made, on which the insulation is laid. Then the floor is sheathed.

Insulation of the ceiling is also absolutely necessary, since the heated air always goes up. A layer of insulation here will greatly save heating costs.

The most popular materials for ceiling insulation: mineral wool, expanded clay, sawdust, polystyrene foam, foam plastic, foam polyethylene. Installation of a heat-insulating layer of sawdust or expanded clay will not be an easy task, as this bulk materials.

But on the other hand, they will be much cheaper than other options, and absolutely environmentally friendly and safe for health.

Warming the house from the inside has one significant drawback - it steals the usable area, therefore, already at the design stage, it is necessary to take into account the thermal insulation layer.

In addition, if there are errors with ventilation, inside the created “pie” of insulation, vapor barrier and cladding, the tree may begin to rot. If all these dangers scare you, then the easiest way is to perform insulation from the outside.

With the help of external insulation, you can transform the facade of the house, protect it from the effects environment, save interior space of rooms.

There are several ways to insulate walls from the outside. This is:

• construction of a ventilated facade;
• facade cladding with foam;
• spraying on the walls of polyurethane.

The best option is a ventilated facade. It will not only protect against heat loss, but also create sound insulation.

Installation of insulation is carried out at a certain distance from outer wall. The air gap prevents the timber from rotting or freezing.

The ideal materials for external insulation are foam, mineral wool or glass wool.

A ventilated facade is also good for a huge selection of materials for cladding. It can be siding, lining, composite, brick, block house, facade board, lath profile, porcelain stoneware.

Colors of finishing materials can also be very different. Ventilated facade - durable construction. The service life here can be 50-55 years.

A thin layer of polyurethane foam applied through a sprayer is ample protection for a home. Therefore, this option is also acceptable.

Insulation of a house from a bar from the outside and from the inside - how to do it right?

Insulation of a house made of timber is necessary if you want a warm wooden house in winter.

Unfortunately, this is one of the disadvantages of a wooden house - sooner or later it will be necessary to insulate its walls and corners.

The article talks about how to properly insulate a house, what types of timber are and what is better to use for insulation.

General points

• General points
• Features of insulation
• What is glued timber?

Many people ask themselves whether it is necessary to insulate a house from a bar, although warming a house is very important point in the design and construction of housing.

Unfortunately, although the tree has a number of positive qualities, it also has its drawbacks - you need to do the warming of the corners and walls of the house in time. As for the walls, it is better not to insulate them from the inside.

Despite the fact that everyone loves a tree very much, its thermal conductivity is lost over time, it is necessary to insulate the home.

In addition, wooden walls are thinner than any other material, so there can be gaps that allow drafts and cold air to pass through. Therefore, before the onset of cold weather, it is advisable to check the walls in time.

To insulate a house from a bar from the outside, you need to choose the right material for the walls and other parts of the home.

Shops offer a wide variety of possible heaters both inside and from the inside of the house.

Some use mineral wool for walls and the whole house, someone prefers polystyrene foam, etc.

Just remember that the method of insulation should be one - either inside or outside. The material and the insulation technique itself will depend on this, otherwise the result will not be the same.

Insulation of a wooden house is often carried out using mineral wool, since it is a safe material that is difficult to ignite and easy to work with.

They use cotton wool to insulate a wooden house with their own hands from the outside, in addition, it perfectly retains warm air.

Usually, after the cotton wool is laid, you can make the cladding of the house with the material that you like more.

Some use plank wall cladding to keep the look of the house, while others prefer plastic siding.

Internal way insulation is used in cases where they do not want to spoil the appearance of the house. But such insulation requires increased accuracy and literacy - not everyone can do it right with their own hands.

Such insulation is more difficult due to the fact that gas exchange in the premises may be disturbed. After the house is insulated from a bar, part of the space inside the room is lost, because of this it seems smaller.

For this reason, it is better to carry out the insulation of the house from the outside with your own hands - it is easier and there will be no unnecessary problems.

So before you start work, you need to decide which part of the house will be insulated, which material is better to use for walls, roofs and floors.

If the insulation is done by hand, then you need to find out how to properly insulate a house from a bar.

Features of insulation

High-quality insulation of walls and the whole house depends not only on the selected materials, but also on other factors - on the quality of the timber and how old the building is. Many are wondering how to insulate a house from a bar.

A good result is influenced by weather conditions and the microclimate from inside the house. When insulating, one should not forget that it is necessary to insulate the corners of the house and the floor - this is also very important, because if there are cracks in it, you can easily catch a cold.

You also need to remember that the roof of the house is insulated from the inside using mineral wool, sometimes it can be replaced with polystyrene foam, which can also be suitable for walls.

The material for the roof must be given special attention, otherwise warm air will rise up and cool if the roof is not insulated from the inside.

Slots in door and window openings are best sealed with mounting foam. If the window is old enough, then a film for thermal insulation and tubular rubber insulation will do.

If the insulation of the house is carried out correctly, then such a dwelling will keep cool in hot weather and warm when the cold comes.

Many people have a question, is it necessary to insulate a house from a 150x150 bar from the outside? Insulation for a house made of timber of this size is necessary and even necessary, since such a dwelling freezes significantly in winter.

Even if the house is made of glued beams, insulation is still necessary if there is a desire to live in it even in the cold season.

In addition, the insulation of such a house will not only make it more comfortable for living, but also protect it from damage to the material due to the effects of nature.

Mineral wool is best laid between the beams, but if this material is used, then care must be taken that it is not exposed to moisture, otherwise it will quickly deform and be damaged.

The roof must be insulated using foam in combination with cotton wool. Penoplex can be replaced with polyurethane foam or some other material.

In principle, the insulation of such a house is not a particularly complicated process. Problems can begin with the installation of a protective system for the facade, since a house with such a beam size (150x150) will require quite a lot of layers of insulation material.

In addition, facade cladding requires not only accuracy and precision, but also the right material.

For this, all types of siding (metal, vinyl, aluminum), as well as a block house, can be suitable.

Sometimes they use lining, which can successfully replace a block house. As mentioned above, it is better to insulate a wooden house from the outside so that the walls do not start to rot from the inside due to the formation a large number condensate.

In addition to hesitation about whether it is worth insulating a house from a 150x150 bar, people have questions about whether it is necessary to insulate a house from a 200x200 bar.

Of course, such a bar is thicker, which means it keeps heat better, but still not enough to refuse additional protection from the cold.

Even if the house is made of glued laminated timber of this size, it is still better to insulate the house at least with your own hands. For such a house, a layer of insulating material with a size of at least 5 cm is required.

What is glued timber?

There were enough references to such a beam in this material, but not everyone knows what it is, what its features are and whether insulation of glued beams is necessary.

Manufacturers have been puzzling over how to make wood more durable and less prone to cracking and other deformations for quite some time.

Such material is in demand because of its environmental friendliness and safety for humans, but, on the other hand, the tree inevitably deteriorates, such houses require processing and accuracy.

One of the solutions to these problems was the manufacture of glued beams.

The principle of its production is that the plates for such a house are glued together, and before that they are treated in every possible way with cleaning and fire-fighting substances. Usually such plates are made from coniferous wood.

To connect the materials together, to "join" them, use mini-seams. As a result, a material is obtained, when using which there are fewer gaps and crevices in the house.

It is for this reason that glued beam houses are being built more and more often. But, despite the popularity and convenience in construction, nevertheless, such a beam has its drawbacks.

When buying glued laminated timber, you need to carefully check it, especially you need to ask about impregnation. If the product is not properly processed, then very soon the plates will begin to rot and deteriorate.

If impregnation is present, then you need to look or ask about its composition. In the manufacture of such solutions, phenol is often used, which adversely affects human health. So it is best to buy such a bar from trusted and well-known manufacturers.

Another disadvantage of glued laminated lumber is that it is quite expensive compared to conventional or rounded lumber.

However, if the house is planned to be used only in spring, summer and early autumn, then the house made of glued laminated timber may not be insulated.

We learn to insulate a house from a bar from the outside and from the inside

Due to the fact that the climate in our country is quite severe, private houses, especially houses made of beams, are recommended to be insulated to achieve maximum comfort. In order for the microclimate in the room to be normal, the bars must be at least 0.4 meters in diameter.

But such a house will be very expensive (remember at least thermal insulation or sealing cracks). For this reason, we are forced to insulate the house both inside and outside. Let's consider,

Introductory instructions for home insulation

How to insulate a house from a bar correctly

Insulation of the house from the outside

Of course, it is best to insulate the building from the outside - this will not only give it additional strength, but also save you free space in the house. And at the same time, the moisture that gets inside the walls from the room will freely leave it and dissolve in the atmosphere. Here are the main advantages of such insulation:

1. The facade of the building completely changes its appearance.
2. The interior space does not change.
3. Heat is much better retained in the house, as a result of which heating costs are reduced.
4. Various negative factors practically do not affect the surface of the walls.
5. Between the layers of insulation there is a special gap designed for ventilation.

There are several ways to externally insulate a wooden house:

1. Hinged facade with ventilation.
2. Sprayed with polyurethane.
3. With the help of foam.

The best option is considered to be a hinged facade with ventilation, as it is more resistant to external irritants, it is quickly assembled and it can last you up to fifty years. How does the warming process take place?

First stage.

We take a heater and fasten it to the outer surface of the walls of the house, after which we cover it with some decorative material.

Second phase.

It is necessary to leave a small free space between the insulating material and the surface of the walls - this way the room will be ventilated, and the wood will not dampen.

Third stage.

Regarding the insulation itself, it is quite possible to make it yourself. Agree, most heaters are subsequently lined with siding, so we will consider this particular option. By the way, we will mount the insulation on a wooden grate.

Materials for external insulation

1. Level.
2. Ladder.
3. Roulette.
4. Sufficient number of screws.
5. Hacksaw.

In addition, materials for a wooden lattice and, accordingly, siding and insulation will be required. It is also worth noting that any heat-insulating material (foam plastic, mineral wool, and so on) can act as a heater.

Each of the options will have its own characteristics and advantages, but there are a number of requirements that they must meet:

1. Environmental cleanliness.
2. A good barrier to the exchange of heat between the room and the external environment.
3. Excellent thermal insulating properties.

As a result, I would like to note that the insulation used to finish the house from the bars should not be stored outdoors during operation - when it gets wet, it will significantly lose its insulating properties.

Also, when working with such materials, one should not forget about personal protection: gloves, a respirator, and so on.

Using polyurethane foam to insulate a house from the outside

This technology also has some undeniable advantages:

• such material practically does not burn;
• it is very easy to apply;
• it is durable (while its properties are not reduced in any way);
• polyurethane foam is environmentally friendly;
• it does not decompose over time;
• it does not need to be additionally fixed;
• In addition to thermal insulation, polyurethane foam is also able to isolate noise.

Do-it-yourself internal insulation of houses from beams

As we have already said, it is better to insulate a wooden house from the outside. But if for some reason this is not possible, then there is nothing left but to insulate the house from the inside. For this, fiberglass mats or URSAP-15 class plates can be used. Where do we start? Let's get a look.

First stage.

We will start by making a frame that will be located on the wall of the house. To do this, we need small (0.5 by 0.5 cm) wooden bars, which we will fix at a distance of about 5.8 cm from one another.

It would seem, why such dimensional accuracy? Everything is simple here: this is due to the size of the insulation mats used.

Second phase.

We lay the insulation quite tightly into the structure, while it must be remembered that there should not be any voids between all its elements.

Third stage.

We take the second frame, designed for insulation, and fasten it perpendicular to the first. After that, we fill its free space with another layer of insulation, the scheme of this process is already well known to us.

Fourth stage.

It turns out that the total thickness of the entire insulation layer will be approximately 10 centimeters. On top of the entire “sandwich” that has formed, it is necessary to apply another layer - this time protecting the insulation material from moisture and steam. We attach the insulating film to the insulation, and seal all the resulting joints with special mounting tape.

What interventional insulation to choose for a bath

Owners of private houses made of timber do not think about comfort in the cold season so often, because wooden rooms are warm enough, although they lose heat over time.

Nevertheless, sooner or later, insulation work will become a necessity, and we advise you to thoroughly prepare in order to ensure the insulation of a house from a bar with your own hands without any problems.

Timely thermal insulation will reduce the cost of electricity and gas, so let's look at the main stages of this process and watch a video on how to insulate a log house from the outside.

Advantages and possibilities of thermal insulation of the facade

Warming a wooden house from a bar is a simple process that does not require specific skills. Moreover, it has several advantages:

• in parallel, you can transform the facade of your house;
• reducing the thermal conductivity of the room will reduce your heating costs;
• walls will be protected not only from the cold, but also from other seasonal factors;
• do not have to carry out additional interior decoration to keep warm.

There are several options for insulating a timber house from the outside. Foam boards or polyurethane foam spraying can help you with this.

But the most common is a hinged ventilated facade, which involves the use of a heat insulator and external cladding. Proper insulation houses made of timber will protect you from the cold for a long time and will even help to mask outside noise.

Let's discuss its technology and find out what materials are needed to insulate a log house from the outside with your own hands.

External insulation of wooden houses

When fixing the insulation between the facade of the building and the facing material, there remains a free space that performs a ventilating function. It is thanks to the air gap that the bars do not rot, do not freeze and do not accumulate moisture even in adverse weather conditions.

Attention! Most often, a timber house is insulated from the outside under the siding: in this case, a wooden crate is placed to secure the finish. Also for cladding, you can use porcelain stoneware, brick, wood or lining.

It is important to decide what is the best way to insulate a house from a bar from the outside. Many people prefer to use foam, but we do not recommend choosing this material. If he copes with the thermal insulation of rooms made of brick or stone with a bang, then in the case of wooden surfaces additional barriers to air circulation are created.

If you are interested in the walls "breathing", then the best way than to insulate a house from a bar from the outside, these are mineral wool and linen mats. By the way, the second material will have the additional advantage of being completely safe for your health.

We are talking about the standard insulation of a house from a 150x150 bar from the outside, so we will calculate the materials for such an example. Since mineral wool is in the form of slabs or rolls, it will not be difficult to calculate the required thickness.

Advice: choose mineral wool in the form of slabs, as they provide an economical finish and are more securely attached to the walls. Unlike slabs, mineral wool rolls are best used on surfaces that have irregularities and defects.

Before insulating walls from a bar from the outside, it is necessary to calculate the consumption of insulating material.

In conditions of extremely low temperatures, it will be necessary to create two or three protective layers of medium thickness: this option is more reliable than one layer of material with large parameters. The standard thickness of the plate will be 5 or 10 cm.

In the presence of 20-centimeter walls, as well as in conditions of falling temperatures not lower than 20 degrees below zero, it will be enough to create one heat-insulating layer.

When temperatures fall below 22-30 degrees below zero, it is necessary to lay out mineral wool in more layers.

In addition to the insulation material, you will have to stock up on slats and bars for the crate. In the case of creating one layer of thermal insulation, you will need slats with parameters of 5 by 5 cm. For two-layer insulation, 5 by 10 cm slats are used. Their number will depend both on the width of the mineral wool layer and on the distance between the “sections” of the crate.

Another material you will need - wind protective film . Such a film has diffuse membranes and promotes the passage of steam and moisture from the insulating material, but prevents the penetration of wind and moisture inside.

The diffuse film is fixed with a special stapler. Also needed for work anchors, screws, and if desired - also an anti-fungal agent. We recommend opting for products with additional protection against ignition.

Stages of thermal insulation

Now let's figure out how to properly insulate a house from a bar from the outside.

Insulation of a log house from the outside is carried out in several stages:

• surface preparation;
• formation of a waterproofing layer;
• creating a crate for insulation outside a wooden house;
• fixing the insulation;
• installation of the second waterproofing layer.

At the first stage, it is necessary to clean the surface as much as possible and treat it with emulsion agents against fungus, insects, bark beetles and other pests. You should not save on preparations and leave some areas untreated, because after insulating the walls of the house from a bar from the outside, you will no longer be able to influence their condition.

Advice: treat the walls of the house in sunny and dry weather so that the walls dry quickly.

Before you insulate a log house from the outside with your own hands, you will have to protect walls from moisture. For this, special membrane coatings are suitable. The stronger the film, the better., as the walls will be protected for a long time. A high-quality membrane film will allow not only to keep the walls dry, but also to bring accumulated moisture out in a timely manner.

Any film of this type has a smooth surface on one side and a rough surface on the other. It is on the fleecy side that all excess moisture will pass through, so glue waterproofing material this side to the wall. Place the protective coating with an overlap of 10-15 cm, and also glue each joint with tape.

Next stage - creating a crate. Measure the width of the insulating plates - and proceed to fixing the wooden slats: the step between them should be less than these parameters by a couple of centimeters.

The first wooden beam is fixed in the corner zone of the structure. Use self-tapping screws for mounting. After installing it, proceed to fixing the remaining bars at the calculated distance.

To perform this work qualitatively, first leave the markup on the surface of the walls. It should be flat, so use the building level and scales. After completing the stage of creating the crate, once again make sure that it is even both horizontally and vertically.

Next stage - insulation installation- is the most important in these works. After it, waterproofing is carried out again, and this is done in the same way as the method already described, so we will not stop at this stage. Let's take a closer look at how to fix the insulation for a timber house correctly.

How to fix the heat insulator

The procedure for installing a heat insulator is not particularly difficult. Firstly, mineral wool can be cut to the required parameters. Secondly, this material is quite light in weight, so fastening in the crate will be quick.

The greatest difficulty will be the insulation of the corners of a log house. Cover the corner with insulating material - and fasten securely on both sides.

When installing mineral wool boards, there is no need to use glue or fasteners: the protective film and facade cladding will ensure the durability of this material. But this is only possible if the recommended ratio between the width of the insulating plate and the distance between the rails is strictly observed.

Important! Make sure that the material “lays down” tightly, and there are no gaps and free spaces on the surface.

And here is a simple way to insulate a house from a 150x150 bar from the outside, if the specified parameters do not meet the requirements. If you cannot fix the plates tightly, use anchors that are mounted in 0.5 m increments. Punch through the mineral wool and fix it on the surface of the wall from the timber. Hammer the wide head core into the anchor to help hold the insulation material securely.

You can proceed to the next stage only after the complete “sheathing” of the entire perimeter of the building with heat-insulating material. The waterproofing film, stretched from above, is fixed with staples.

Don't wait a while before starting facade decoration: use clapboard, siding or other cladding to bring the house into a presentable appearance. Exterior finishing technology will differ depending on the type and parameters of the selected material, so this issue must be discussed with specialists.

Modern decoration of houses made of wooden beams using insulation does not cause difficulties even for those who are not strong in construction and repair work. Just needed perform each of the described steps in sequence. Such insulation does not take much time, and you control the costs of the thermal insulation process yourself: the market is represented by protective materials with different performance properties and service life.

Video

A useful video on how to insulate a house from a bar from the outside will help you understand the features of each stage of this process.

Buying Vacation home from a bar, some people believe that wood is a warm material, so a wooden house does not need additional insulation. But it is not always the case. In order for the microclimate in the room to be normal for living in winter frosts, and not to have to pay huge sums for heating, it is necessary that the walls be built from a bar with a thickness of at least 40 cm. But the construction of such a building will be very costly.

Timber house

Most houses outside the city have walls that are not thick enough to withstand severe frosts. Even if you qualitatively seal all the cracks in the log house, this will not make the house much warmer. In order for the log house not to freeze, and the temperature in the room to be normal even in the most severe winters, it is necessary to have high-quality insulation of the log house from the outside. Making a good thermal insulation system is not difficult now. Manufacturers offer customers a wide selection of a wide variety of thermal insulation materials, the installation technologies of which are so simple that they can be performed even by inexperienced and unskilled craftsmen. And to make it easier for yourself when installing heat-insulating materials, you can watch the insulation of a house from a bar outside the video on the Internet with detailed explanations of all stages of heat-insulating work.

External thermal insulation of a log house: main advantages and useful recommendations

External insulation of a log house is carried out using different materials, but all of them must meet this requirement.

• Do not support combustion.
• Have low thermal conductivity.
• Do not select harmful substances, do not have toxicity.
• Made from environmentally friendly materials.
• Good to keep warm.
• Do not accumulate moisture.
• Keep fumes out of the house.
• Do not allow atmospheric moisture to enter.
• Possess soundproofing properties.

Some of the benefits of outdoor insulation include:

• The possibility of changing, transforming or updating the facade of the house.
• Reducing heat loss through building envelopes, reducing fuel costs.
• Protecting the load-bearing walls of the house from adverse natural factors.
• Saving interior space at home.

• When performing installation work, do not leave heat-insulating material in the open air. If the insulation gets wet, it sharply loses its heat-shielding properties.
• When laying the bars of a horizontal crate with a step less than the width of the insulation by 15 mm, they can be laid by surprise, without fixing materials.
• When working with insulation, it is necessary to use personal protective equipment (respirator, gloves, goggles).

Technologies of external insulation

External wall insulation is most often performed in three ways:

• Hinged ventilated facade.
• By spraying with polyurethane (the material is sprayed onto the wall of the house using a special installation)
• Wall insulation with foam.

The most efficient and comfortable view insulation, many experts consider a hinged ventilated facade. Many of its advantages speak in favor of this method, such as:

• Fast installation.
• Large selection of cladding materials (siding, wall paneling, porcelain stoneware, wooden facade board, lath profile, composite, brick).
• High rates of thermal protection and sound insulation.
• Durability (service life up to 50 years).
• Reducing heating costs.
• Facade weather protection.
• The "dew point" is outside the load-bearing walls.

Materials for insulating the walls of a house from a bar

To insulate the walls of a log house, you can use various modern heat-insulating materials. A house made of timber is insulated:

• fiberglass
• Mineral wool slabs
• Basalt mats
• Expanded polystyrene and other materials

Each of these heaters has its own distinctive properties. But when choosing a material for a heat-insulating system for a wooden house, you need to pay attention to whether this type of heat insulator meets the basic requirements.

Heaters for external insulation of houses made of timber should have:

• High heat-shielding properties.
• Fire resistance.
• Moisture resistant.
• Non-hygroscopic.
• The ability to prevent heat transfer between the room and the external environment.
• Ecological safety.

Excellent conditions for insulation and will not allow condensation to accumulate

How and how to insulate a house from a bar

The most popular material for warming log houses is mineral wool. This material is light enough not to create additional load on structural elements building. The cost of mineral wool is not high, it keeps the heat in the house well, but, most importantly, mineral wool is not a combustible insulation. Due to its softness, elasticity, mineral wool is easy to install and does not form cold bridges. In addition, it is resistant to thermal deformations of the walls.

Warming can be done under a block house, or you can sheathe the walls of the house with plastic siding from the outside. Installation of a thermal insulation system using mineral wool consists of several stages:

vapor barrier

Installation of the thermal insulation system of a wooden house begins with a vapor barrier device. To do this, you can use aluminum foil, plastic film, a special vapor barrier film and roofing material. Vapor barrier provides ventilation of the facade under the film.

Vertical slats 2.5 cm thick are stuffed onto the walls, at a distance of 1 meter from one another. Further, a vapor barrier layer is stuffed onto the laid rails on the entire surface of the wall. Holes (20 mm in diameter) are made between the base rails at the top and bottom for ventilation. The presence of a ventilated layer between the vapor barrier and the wall will prevent moisture from accumulating under the film, which could lead to rotting of the wooden wall. The vapor barrier is fastened with nails or staples, the attachment points are sealed with adhesive tape to protect them from water ingress.

Installing the frame for thermal insulation

For the frame, take boards 100 mm wide and 40-50 mm thick. On the wall, the boards are stuffed vertically on the edge. The distance between the boards should be less than the width of the insulation by one to two centimeters.

The beam is attached to the facade of the house with self-tapping screws. When installing a beam, you need to control its position with a level or plumb line. If the crate is unevenly mounted, the installation of the facing material at the final stage of thermal insulation work will be of poor quality.

To install the thermal insulation system of a timber house, it is necessary to install a frame

Laying thermal insulation

Between the boards of the frame, the mineral wool slabs are installed as close as possible to each other so that there are no gaps. Mineral wool 50 mm thick is laid in two layers. They use semi-rigid, elastic, slabs with a density of 80 - 120 kg / m3, they are easily held between the frame boards, without slipping without additional fastening.

Laying insulation between the bars of the frame

Waterproofing

After finishing the laying of thermal insulation, it is necessary to lay a waterproofing film, which should allow steam to pass through, but at the same time retain water. The film is laid on the thermal insulation, nailed with staples or nails of the frame. When joining the film, 5-10 cm of overlap is left, the joints are sealed with self-adhesive tape.

Second frame layer

Laths are stuffed onto the thermal insulation frame over the waterproofing (50 mm wide and 2.5 - 3 cm thick). This is necessary in order to ensure free circulation of air between the sheathing and the vapor barrier, which will dry the condensate that appears on the waterproofing layer. The resulting space is closed from below with a dense metal mesh, from the penetration of insects and rodents into it.

outer skin

The outer skin performs mainly a decorative function. Therefore, what will be the facing material, of great importance does not have. It can be wooden lining, and plastic siding or any other material.

Insulation for thermal insulation of walls made of timber

Recently, many effective heaters have appeared, which are produced on the basis of advanced technologies. One of these modern materials is Penoplex, produced Russian company in the form of thermal insulation boards.

"Penoplex" is a kind of foamed extruded polystyrene foam, prepared using special technologies. The panels are durable and highly resistant to moisture. This material does not have the ability to absorb moisture, is not afraid of dampness, is not a medium for the development of bacteria, mold and other microorganisms.

Plates "Penoplex"

Penoplex boards, due to their high strength, can be laid both vertically and horizontally. The structure of their surface allows the application of plaster.

Penoplex insulation is a material that has a uniform structure, which consists of small, closed cells (0.1-0.2 mm in size).

The main properties of PENOPLEX boards are:

• low thermal conductivity
• low vapor permeability
• lack of water absorption
• high compressive strength
• fire and biodegradability resistance
• ecological cleanliness
• simplicity and convenient installation
• durability

When using foam boards, you should be aware that this material, like other types of extruded polystyrene foam, has low chemical resistance to substances such as:

• Aldehydes (formaldehyde, formalin)
• Aromatic hydrocarbons (benzene, toluene, xylene)
• Ketones (acetone, methyl ethyl ketone)
• Ethers (diethyl ether), do not use solvents with ethyl acetate, methyl acetate,
• Gasoline, kerosene, diesel fuel
• Polyester resins (do not use epoxy resin hardeners or coal tar),
• Oil paints.

Penoplex is resistant to the following chemicals:

• Acids.
• Salt solutions.
• Caustic alkalis.
• bleach.
• To alcohol and alcohol dyes.
• For water-based paints.
• Ammonia, carbon dioxide, oxygen, acetylene, propane, butane.
• Fluorinated hydrocarbons (freons)
• For cement and concrete mortars.
• Animals and vegetable oils, paraffin.

Important! Plates "PENOPLEX" should be used only in the temperature regime recommended by the manufacturer. If the range of recommended operating temperatures is exceeded for a long time, the boards may lose their mechanical and thermal insulation properties and change their dimensions. With Penoplex heaters, only adhesive solutions approved by the manufacturer should be used. Products containing acetone, ethyl acetate, etc. in their composition. lead to softening, shrinkage of extruded polystyrene foams.

Another modern insulation- Polyurethane foam is used to insulate the walls of a log house by spraying.

The main advantages of this method:

• Thermal insulation system based on polyurethane foam is not subject to decay and bacteria.
• The material has long term operation, during which it retains its thermal insulation qualities.
• Does not support combustion.
• Has soundproofing properties.
• A simple way to apply heat-insulating material.
• Does not require additional fasteners.
• Environmental friendliness.

This method of insulation can be used for thermal insulation of walls, plinth, foundation.

It is easiest to insulate a log house with polystyrene foam, but this material has low fire-fighting properties. And since wood itself is a combustible material, many experts do not recommend using foam boards to insulate wooden walls.

The ancient way of building houses from wooden beams has become popular again today. Now such buildings play a role not only country houses, but also full-fledged dwellings for year-round use. Well, in order for the wooden house to be warm in winter, it must be insulated. We will talk about how to properly insulate a log house in this article.

As a rule, it is customary to insulate wooden buildings from the outside. This allows you not to hide the interior space of the premises, and also prevents the wood from rotting. Insulation of a log house from the outside is necessary for several reasons:

1. Thermal insulation of the building protects the walls from heat loss, reduces heating costs.
2. An insulated house is not afraid of high humidity, severe frost and other adverse environmental factors.
3. Being engaged in thermal protection of walls, you can simultaneously install siding, which will allow you to change the appearance of the house at the request of the owner.
4. As already mentioned, external insulation does not reduce the internal space of rooms.

When performing such work, it is important to consider several points:

• choose the right thermal insulation material, calculate its thickness and required amount;
• strictly observe the installation technology;
• do not forget about creating a hydro- and vapor barrier layer;
• properly process wooden walls to protect them from insects, fungi, burning and other harmful effects.

Insulation for a log house must meet certain requirements:

• be of high quality and durable;
• easy to handle and install;
• safe for health, environmentally friendly;
• don't burn.

So that the insulation of a log house is effective, and the building serves you long years, heed the following recommendations:

1. Never use raw material. The insulation must be dry and pre-treated with an antiseptic. If you cover the walls with damp material, the wood will begin to mold, rot, and collapse. Fungi and microorganisms will start in it, and after a while the bars will simply become worthless.
2. It is possible to insulate the walls of a wooden house only after the building has completely shrunk. Such shrinkage, as a rule, takes at least 1.5 years. If the building is sheathed earlier, as a result of subsidence of logs, the lining is deformed.
3. It is possible to mount heat-insulating material only on prepared walls. This means that all deep cracks and chips must be covered with putty, and the wood itself must be impregnated with antiseptics and flame retardants.

How to insulate a log house from the outside: creating a hinged facade

Among the methods of thermal insulation of log buildings, the construction of a ventilated facade is considered the most popular method, the reason for this is the advantages of this method:

• the hinged facade is easy to install, it takes relatively little time to work;
• after insulation, the walls can be lined with various decorative materials: clapboard, porcelain stoneware, siding, boards, rack profile, etc.;
• this method of insulation does not allow the walls to mold and collapse, the dew point moves beyond the outer wall;
• resistance to temperature changes, humidity, precipitation, as well as excellent sound insulation should also be attributed to the undeniable advantages of a hinged ventilated facade;
• such a design is durable, the period of its operation reaches 50 years;
• When insulating walls, you reduce energy costs for heating.

The external insulation of a log house in a similar way can be described as follows:

1. So that moisture does not accumulate in the wood of the walls, a gap is made between the insulation layer and the decorative finishing material, which is why such a facade is called ventilated. To create air space, a crate is installed on the wall. To make it, marks are first placed on the surface where the bars will subsequently be attached. The width between them should correspond to the width of the sheets of insulation material, and the thickness of the bars is selected depending on the thickness of the mats.
2. Having placed the marks, the logs are attached to the walls with the help of self-tapping screws. The evenness of the crate is checked with a building level and a plumb line. It is especially important to ensure that all the bars are located in the same plane - this will later help to make a beautiful, even and high-quality siding.
3. When the elements of the crate are fixed, sheets of insulation are laid between them. They are pressed tightly against the walls and fixed with dowels.
4. To provide the necessary air space, wooden planks are nailed over the crate and insulation layer. Their thickness should be such that the gap is at least 5 cm.
5. After laying the insulation, finish with decorative siding.

Insulation of the house with sprayed materials

Instead of sheet insulation, you can also use sprayed insulation, for example, ecowool or polyurethane foam. Ecowool is a cellulose substance that is made from recycled paper, borax and boric acid. The advantages of such material can be considered:

• environmental friendliness and hygiene;
• good resistance to moisture;
• excellent thermal and sound insulation qualities;
• fire safety;
• non-toxicity;
• non-waste use;
• excellent vapor permeability;
• the ability to fill even the smallest gaps in the walls.

Ecowool has the appearance of a crumbly mass, pressed into briquettes. Before use, such briquettes are opened, their contents are poured out and dried.

If you want to use polyurethane foam as a heater, check out the advantages of this material:

• like ecowool, polyurethane foam is fireproof;
• it has good sound and heat insulation properties;
• considered an environmentally friendly type of finish;
• its service life is quite long, and during this entire period the material does not lose its properties;
• polyurethane foam is not subject to decay, mold does not form on it, insects and microorganisms do not damage it;
• ease of installation due to the fact that it does not require the use of special fasteners.

To insulate walls by spraying, you will have to acquire special equipment. You can buy it, or you can rent it and save money. The process itself looks like this:

1. Even before purchasing the material, you should calculate its required amount. To do this, measurements are made of the area of ​​\u200b\u200bthe working base, and the consumption of the sprayed insulation is also taken into account.
2. Then, on the wall of the log house from the outside, a crate of wooden planks or metal profile. Subsequently, decorative finishing material can be attached to this crate.
3. Using a special installation, ecowool or polyurethane foam moistened with water is sprayed between the lathing bars. Often, when soaking cotton wool, adhesives are added to the water, which will allow the insulation to adhere more firmly to the surface.
4. Having processed the walls of the house with a pneumatic sprayer, the material is left until it solidifies completely.
5. After that, the excess insulation is cut off with a knife, and siding is mounted on top of the crate.

Thermal insulation of the house from the inside

Is it worth it to insulate a wooden house from the inside?

Few people dare to mount insulation on the inner surface of the walls of a log building. Warming a log house from the inside is not popular for several reasons:

1. This method of thermal insulation of the building can lead to the accumulation of moisture in the walls, due to which the wood will rot, mold and collapse. It is highly undesirable to use a similar method in baths and saunas, where the air is constantly saturated with water vapor. In winter, when the wood freezes, the dew point is located between the walls and the insulation layer, as a result, condensate accumulates there, which destroys the structure. If you create a good ventilation system in the house, then such problems can be leveled.
2. The second reason why the walls of log houses are rarely insulated from the inside is the loss of usable area. The space of the rooms is reduced by at least 3-4 cm on each side, and this is especially noticeable in small rooms.
3. The insulation layer also hides the natural beauty of the log cabin, which is not to the liking of lovers of natural interiors.

However, sometimes owners wooden houses resort to this method for various reasons. Some, for example, do not want to hide the appearance of the house under a layer of insulation and siding. Someone wants to veneer the interior walls with some kind of decorative material. Regardless of the reasons, the technology of internal insulation of premises should be conscientiously observed so as not to spoil wooden bars and not shorten the life of the building.

The better to insulate a timber house from the inside

For thermal insulation of internal walls, only eco-friendly materials that will not release toxic substances into the air. For example, polystyrene foam is not suitable for such a purpose for several reasons. Firstly, it does not have vapor permeability and does not allow the walls to "breathe". The room turns out to be absolutely isolated, there is no necessary natural air exchange in it. Secondly, during combustion, the foam releases very toxic substances into the air, so that in the event of a fire it is considered an extremely dangerous material.

You can insulate the walls with mineral wool. It is environmentally friendly and does not burn, has good vapor permeability, high thermal insulation characteristics. The most significant drawback of such a heater is that small particles are released into the air, which are dangerous for the respiratory tract. If the cotton wool is covered with a layer of film and finishing, then you can ignore such a minus.

Very often, materials that are completely environmentally friendly and safe in all respects are used for internal wall insulation: linen, jute, wool. Such means of insulation are economical and effective, protect the building from the cold and extraneous sounds, provide good air exchange through wooden walls.

How to insulate a log house from the inside with your own hands

1. The first step is to carefully inspect the walls for cracks, chips, damage, and the quality of the caulk. All shortcomings are eliminated, cracks are covered with putty. Dirt and dust are removed from the logs, after which the bars are impregnated with antiseptic compounds. If electrical wiring runs along the walls, it is also checked and, if necessary, repaired.
2. After the antiseptic impregnation dries, cracks are caulked in the walls. For this purpose, jute fiber is used, which is thrust into the gaps with a chisel.
3. Before insulating a log house, it is also important to take care of creating a vapor barrier. So that the heat-insulating material does not get wet, it is customary to cover it on both sides with a layer of vapor barrier film. Because of this, the humidity in the rooms will increase, in order to avoid this, you should arrange good ventilation in the house.
4. When laying the vapor barrier material, it is placed with its smooth side against the wood so that the moisture from the logs does not impregnate the insulation.
5. The next step is the installation of the crate. Wooden bars or metal profiles are stuffed along the load-bearing walls. The step between the boards should be equal to the width of the mats of the heat-insulating coating. Mounted in the corners of the room corner posts so that the corners are even and beautiful. The crate is fixed on the walls with self-tapping screws, using a level, its evenness is checked. If wood is used for the frame, it, like the walls themselves, is also impregnated with antiseptics.
6. Between the details of the crate, sheets of insulation are laid, for example, mineral wool. A fragment of the required length is cut from the roll of material and installed between profiles or bars. It is desirable that the width of the sheet be 1-2 cm greater than the distance between the frame parts. Straightening, cotton wool fills the entire space and does not require additional fastening. If the insulation itself does not hold very securely, you can fix it with dowels.
7. Another layer of vapor barrier film is laid on top of the mineral wool. Its fragments are overlapped and connected at the joints with adhesive tape. The vapor barrier is nailed to the insulation with a stapler. Remember also that the film must be placed with the rough side towards the interior of the room.
8. The final stage of work is the finishing of the walls. The easiest way is to install drywall sheets on top of the crate, after which they can be painted, covered decorative plaster or wallpaper.
