To sheathe insulate a wooden house from the outside. Insulate a wooden house from the outside with your own hands

It would seem that the question is quite simple - and the methods have long been worked out, and the choice of thermal insulation products is significant. But this is not about any building, but about a wooden house. Regarding its insulation, there are a number of nuances that cannot be neglected.

It's all about some features of such a building material as wood. First of all, it is its susceptibility to decay, the ability to "breathe" and retain heat well. The last two properties allow you to maintain comfortable conditions in the premises, as a rule, without significant additional costs. For example, for the purchase (and professional installation) of climatic equipment, due to the increased consumption of en / resources (including fuel for the boiler). At least, the indicated devices are not used as intensively in wooden houses as in brick or cellular concrete buildings. So, let's consider in detail how and what is the best way to insulate a wooden house.

To make the technology of work clearer, it should be explained why insulation from the outside for a wooden house is the only right solution. This method of reducing heat loss is the main one for any buildings, as it has a number of advantages. For example, does not reduce the usable area. This is one of the disadvantages of arranging this protective layer from the inside. But for a log house, something else is more relevant.

It's all about the so-called "dew point". The external installation of the insulation takes it outside the perimeter of the house, and condensate forms in the ventilated space. Consequently, in cold weather, the tree does not freeze, and in warm weather, the process of decay does not begin. If the insulation is laid on the walls of the premises, then the “point” shifts inward. As a result, the logs (beams) remain unprotected, and the condensate settles in the thermal insulation material, which initiates the development of mold and fungus not only in it, but also in the rooms.

How to insulate a wooden house

If you delve into the details, then the choice of materials is not so big.

Styrofoam boards

They differ not only in the correct geometry, but also in "rigidity". Therefore, to fix them, it is necessary to carefully align the base. It is still acceptable for a beam, especially if the walls were erected by professionals. And what about logs? In addition, foam plastics do not let in not only moisture, but also air. Therefore, the main attraction of a wooden house - climate control - will be completely leveled.

Spray formulations

Usually polyurethane. There are even more disadvantages, besides, special equipment will be needed. But the companies providing this service (for PU insulation) are silent about another rather significant disadvantage - the low maintainability of the layer. After all, it sticks to the surface on which it is applied. If, in the literal sense, it can still be “picked out” from a brick or concrete goods, then what about the tree? After all, it is quite malleable to mechanical stress, and damage to logs or timber in this case cannot be avoided.

There are other types of insulation for wooden buildings, which are advised to use the authors of some articles. But all the listed materials (chipboard, flax fiber, etc.), taking into account the specifics of the log house and in terms of durability, hardly deserve attention.

To insulate buildings made of wood, only mineral wool should be used. Excellent vapor permeability, elasticity, low weight - in fact, such thermal insulation fully complies with all the main criteria for a wooden house.

Warming the house from the outside - how to do it

Surface cleaning

This is where any repair or finishing work begins. For a wooden house, the initial inspection is especially important. It is necessary to identify all foci of damage to wood, determine their nature, methods and means to eliminate defects. This is a separate topic, and.

Processing with special / preparations

For a wooden house, both are equally relevant - flame retardants and antiseptics. Features of their use and formulation are indicated on the packaging. It is clear that it is desirable to do this in positive weather and clear skies.

All types of wood differ in porosity. Although more often they talk about the hardness or density of lumber. Based on this, the appropriate compositions should be selected. Their list is quite large, and the specifics of the application can vary greatly. The best ones are those that penetrate deep enough into the structure of the material and do not "close" the pores. Otherwise, the tree will not be able to "breathe".

Installation of a vapor barrier layer

Its main purpose is to ensure the ability of wood to self-regulate the microclimate and at the same time protect the material from direct contact with moisture. There are many varieties of films and membranes on sale. If the first option is chosen, then it must be taken into account that all samples differ in their execution, and therefore, in the specifics of use. The film is cheaper, but the usual modification of polyethylene cannot be used for vapor barrier. It is hermetic, and together with water does not let air through. It is worth considering when choosing products.

Mounting on the outside of a wooden house is quite simple - using a construction stapler (staples). It is only necessary to take into account that the strips must be mounted with a slight "overlap", and the joints must be closed with adhesive tape (adhesive tape).

The construction of the supporting frame

It is also called a crate. What is its peculiarity in relation to a wooden house? The coefficients of thermal expansion of the materials to be bonded should be taken into account. Metal slats are much more convenient for installation, but since the house is made of wood, it is not advisable to use them. Only wooden bars of the appropriate length and section.

The dimensions of the seats (cells of the crate), as well as its design, are selected based on the geometry and design of the insulation. Mineral wool is sold in slabs or rolls, so it is not difficult to draw up a sample laying pattern.

Another nuance concerns fasteners. Self-tapping screws or screws should not be used for fixing elements of the crate. They "tightly" grab the supporting structure, and this should not be. A wooden house “plays” somewhat under the influence of external factors (a feature of the material), therefore, fastening the crate to it is only with nails.

What to consider

The reliable position of the insulation is ensured by the fact that during the laying in place, the samples are slightly compressed. Then, due to their elasticity, they straighten out somewhat, which determines their reliable "hitch" with the slats of the supporting frame. When calculating its parameters, it is necessary to choose the cell sizes so that they are slightly smaller than thermal insulation products. Then you do not need any of their additional fastening on the outside of the house.

Laying insulation material

There is nothing complicated about this, especially if the scheme is drawn up correctly. Mineral wool is well cut with an ordinary knife, they bend, so there will be no problems.

Peculiarities:

• On problem areas of the walls (complex configuration, slope, etc.), it is worth additionally fixing the thermal insulation with special nails - anchors.
• The gaps at the junction of the insulation to the frame rails are sealed with the same construction tape.
• Installation of thermal insulation is carried out in the direction from the bottom up, in rows.
• In regions with frosty winters, insulation (depending on the thickness of the samples) can also be laid in 2 layers. In this case, the plates for the second are cut so that after installation their joints in the rows do not match. That is, a mount with a slight offset.

Each person dreams of a warm house, so that even in the most severe frosts it would be comfortable to be indoors. Therefore, the first question that confronts the owners of their home is how to insulate the walls from the outside on their own. This is especially true for wooden buildings. In this article, we will give instructions according to which the walls of frame and timber houses are thermally insulated from the outside. And for a more visual 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 massively used by consumers.

Warming a wooden house will help keep the wood from destruction

Stone wool in slabs. Such material is easy to cut even with a conventional knife. Due to the light weight of the plates, it is easy to transport even in a passenger car, especially if you need to insulate a small area. During installation, stone wool is placed in the gap between the racks of the frame, and then insulated with vapor barrier material from the inside and waterproofing from the outside.

Attention! During transport or installation, never compress or tamp the mats.

Ecowool. This is an environmentally friendly material for insulation, based on cellulose fibers. Produced in a package, in a slightly compressed form. There are two ways to insulate this material:

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

Insulation of a wooden house from the outside

Styrofoam. One of the most budgetary types of insulation. This material does not absorb moisture, so it is not necessary to cover it with a moisture-proof membrane. However, when working with foam, you need to show maximum accuracy, because it can crumble and break.

Attention! As a heater, you need to purchase non-pressed foam sheets.

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, such material is similar to mounting foam. They fill the voids in the wall, and cut off the excess. The result is a monolithic layer of insulation, which completely eliminates heat loss. Polyurethane foam has water-repellent properties.

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

What is the best way to insulate walls?

The key to a quality repair is a well-thought-out work plan. Therefore, it is worth considering in advance how you will insulate the walls: from the inside or 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 side of the street. Because of this, mold and fungus may appear inside the structure, and the tree itself will begin to rot. In addition, it is necessary to buy material that, in its properties, will match the tree. Linen fiber, soft fiberboard, basalt and fiberglass materials are suitable for this.

House insulation with mineral wool

With the external method of thermal insulation, a uniform layer of insulator is formed for the free release of vapors. The insulation is less dense than wood, because of this, steam escapes through the ventilation gap. The external method of thermal insulation is an ideal option for those who want to insulate old houses made of timber, which have lost their “presentation” over time, after sheathing they will look like new. However, if the walls are not properly insulated, the wood will begin to deteriorate, and under a layer of exterior finish, you will not be able to control the condition of the wood.

Insulation of the walls of a frame house with mineral wool

Thermal insulation of a frame house begins with waterproofing. To do this, you can use glassine - a cheap but effective material. It is cut into strips and fastened with a stapler 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 will be sheathed 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 plates are easily cut with a construction knife. The laying process is simple, first we measure the distances between the racks and add 5 cm on each side for allowances. We cut the sheets of the desired 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 foam phenol. It must be shot to the frame of the building using a construction stapler. Penophenol is laid in a horizontal direction, leaving 5 cm joints with the foil part outward. After that, we sheathe the walls of the house with edged boards or siding.

Insulation of the walls of the frame house with foam plastic

In order to fix the foam on the wall, first we install vertical canopies from the cord. Then glue is applied to the foam sheets, along the edges and at five points inside, and fixed on the wall. Thus, the entire insulation is laid. Next, you need to seal the gaps with mounting foam. For additional strength, we fix the sheets with plastic dowels.

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

Outside, the walls must be plastered, and before that, a reinforced mesh must be mounted. Putty will help protect the structure from the influence of external factors, but it should be applied in two layers. After the surface has dried, a finishing layer can be applied with decorative plaster.

Insulation of the walls of the house from a bar

External insulation of houses made of timber should be made 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 smeared with an antiseptic to prevent decay. Then basalt wool is attached to it with the help of self-tapping screws or dowels-umbrellas, for 1 sq.m of insulation - 4-6 fasteners. A diffusion membrane is laid on top as a waterproofing agent. We nail slats on top of the wooden frame, 5 cm thick, which will create a ventilation gap to remove moisture. Then we nail the profiles to the rails and install the siding, starting from the bottom, checking the horizontal laying with a level.

Scheme: home insulation

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

Warming the house with mineral wool: video

Often there are situations when the walls in a wooden house lose one of their tasks, such as heat retention. In this case, they resort to warming the walls of the house from the outside. The insulation becomes a protection against cold air.

This approach also has several other advantages: the wall of the building gains additional protection from sunlight and moisture and will last longer.

Advantages of external thermal insulation

External insulation of the house has several advantages:

1. The main one, of course, is the preservation of heat. This type of insulation prevents a sudden drop in temperature. The wall, reinforced from the outside, retains high thermal protection.
2. Unlike internal insulation, with external insulation there are no zones in which there is no heat, the so-called "cold bridges" since with this type of insulation it is possible to install heat-insulating material at the junction of the ceiling to the outer walls.
3. Also, external insulation prevents the penetration of moisture into the walls of the house.

Do not forget about the shortcomings of external insulation. Such a process of warming wooden houses is quite complicated and time-consuming.

Warming methods

There are several types of insulation:

1. The insulator is attached to the wall with adhesive solution.
2. Facade ventilation. The wall is protected by waterproofing, a heater is attached from above, a windscreen is installed, after which the sheathing with siding or other material is installed on the frame.
3. Three-layer non-ventilated wall. The insulation is fixed with mortar, the outer wall is mounted in one brick, while observing the air gap.

It is natural that for each type of material there are subtleties in execution. It should not be ruled out that there are combined insulating materials on the market of insulating products or such materials for which it is necessary to adhere to the technology developed in-house.

What material is better?

There are several types of materials for thermal insulation, and before deciding which insulation would be best for you, you need to know their characteristics.. So, let's figure out how you can insulate the walls of a wooden structure.

Mineral wool

The most common material. It has a fibrous structure, which is formed as a result of spraying molten glass, rocks, slag.

The advantages of mineral wool insulation include good throughput, heat resistance, high stability index, guarantees noise protection, high service life.

But this type of insulation has a significant drawback - mineral wool can release phenol dangerous to humans.

Windproof plates Isoplat

Isoplat is a fibreboard made from softwood fibers without the addition of chemical components and glue. Such plates are natural and effective as the tree itself. In terms of thermal insulation properties, 12 mm board = 44 mm solid wood. Plates are available in various thicknesses. In addition to excellent insulating properties, they provide additional sound insulation.

The advantage of Isoplat is that the material does not deform over time, does not wrinkle or tear. In addition, being a "breathable" material, Isoplat protects walls from fungus and mold.

Installation of plates is very easy - press against the wall and nail. Above is a ventilated façade. Such insulation of a wooden house can be easily done with your own hands without the involvement of specialists.

polyurethane foam

A type of plastic filled with gas. It has a cellular structure and is filled with carbon dioxide, air or other gases.

The advantages of PPU are high thermal conductivity and vapor permeability, high waterproofing properties, high safety, non-toxicity. The disadvantages include low fire resistance. Also material is quite expensive and ages over time, which has a bad effect on its heat-insulating properties.

Basalt slabs

Manufacturing method - molten rocks. Advantages - high vapor permeability, the presence of water-repellent properties, chemical and biological stability, sound insulation.

The big plus is safety. Such a heater is environmentally friendly. The only downsides are high price.

Styrofoam

A material filled with gas, like polyurethane foam. It is obtained from polystyrene and its derivatives. Such material is vapor permeable, absorbs water well, biologically stable, long service life. These are definitely positives.

Of the minuses - highly flammable, which makes it a rather dangerous material.

The most popular material for external insulation of wooden houses. It has a cellular structure. cells are isolated, polystyrene has good thermal insulation, which is definitely a plus.

Styrofoam insulation also provides good sound insulation, no need for additional waterproofing, ease of installation and durability.

Like all materials, polystyrene also has its drawbacks: it is unsafe. when burned, caustic substances are released, has low strength.

When choosing a thermal insulation material, you should pay attention to its service life, safety. The choice of material for insulation should be approached responsibly, to study all the pros and cons. Preference should be given fireproof and environmentally friendly materials.

We warm a wooden house with our own hands

The insulation technology begins with the installation of a frame on which the insulation will lie.

Bars are nailed to the wall being processed made of wood measuring 50x50 mm, keep in mind that the distance should be no more and no less than 580 mm of security. The material must be laid so that there are no gaps between the wall and the bars.

Next stage - providing vapor barrier. For this, aluminum foil, polyethylene film or vapor barrier film is used. The need for vapor barrier is eliminated if the house is made of round timber.

When the plane is smooth, then the slats are stuffed, on which a layer of vapor barrier is mounted. It must be taken into account that between the slats from below and above there should be a stomata of 20 cm in diameter for ventilation. The fastening points of the vapor barrier material are sealed with adhesive tape in order to protect against moisture.

The stage of vapor barrier is followed by the stage of thermal insulation. The material must be installed so that there are no gaps or gaps between the frame boards. The material is laid in two layers of 50 mm each. so that the joints of the first layer are aligned with the middle of the second.

For the secondary layer of thermal insulation bars are nailed across walls, perpendicular to the main row of the frame.

Next is waterproofing. The waterproofing film must easy to pass steam and hold water well. The waterproofing layer is superimposed on the heat insulator layer. It is nailed to the frame.

Next is the stage of installing a secondary layer of the frame. On the first layer (on top of the waterproofing layer), slats 50 mm wide and 30 mm thick are stuffed.

The installation of the next layer of the frame is carried out for free air movement between the vapor barrier layer and the skin, so that the moisture that has fallen on the waterproofing layer is dried.

The space formed below must be closed with a dense metal mesh from the penetration of rodents and insects.

At the last stage, the house is sheathed with appropriate material (siding, wall paneling, facade panels, and others). It should be taken into account that wall thickness will increase by 20-25 cm and accordingly, it is necessary to think over the protection of the insulation from the window openings.

How to insulate the walls of a wooden house outside with your own hands and what is better?

How can you insulate a wooden house from the outside? How to do it yourself? Varieties of material.

Proper insulation of a wooden house from the outside

Before insulating a wooden house from the outside, you need to correctly select all the materials. The building made of wood has its own characteristics. First of all, it is worth remembering why wood still retains its popularity. There are several reasons for this:

• good thermal performance;
• providing a comfortable microclimate in the building;
• environmental friendliness;
• security;
• the ability to pass air (the tree "breathes").

The insulation of a wooden house from the outside should be chosen so that all materials do not reduce the useful properties of wood. But sometimes it is difficult to do so. To choose a good insulating material, you will need to spend your time and study the basic information on the issue.

pie wall

Before insulating a wooden house from the outside, it is recommended that you familiarize yourself with the composition of the wall. After that, you can begin to select all the necessary materials. The technology of warming a wooden house from the outside provides for the following layers:

Vapor barrier and waterproofing are required to protect the material from moisture. Many types of thermal insulation are destroyed or cease to perform their function when exposed to water.

The choice of insulation

What is the best way to insulate a wooden house from the outside? The most popular materials in the construction market are:

• mineral wool;
• Styrofoam;
• extruded polystyrene foam or Penoplex.

Each of these options has its own advantages and disadvantages that you need to consider before deciding how and with what to insulate your own home.

Insulating a wooden house from the outside with your own hands in this case will be the cheapest. It can be bought almost everywhere. There are different types depending on the strength. Polyfoam has good thermal insulation performance, but the disadvantages include:

• combustibility;
• low strength;
• resistance to mechanical damage.

Insulators for the walls of a wooden house of this type are not recommended for one reason: the foam practically does not let air through. This means that all the useful properties of wood, for which it is so valued as a material for building cottages, are coming to naught.

Insulating a house made of wood with polystyrene foam is a rather pointless procedure. Yes, the room will be warm, but at the same time, the temperature and humidity regime will be disturbed due to lack of ventilation. The natural air exchange in the room is blocked, the arrangement of forced ventilation or air conditioning is required. Both options involve additional (and not small) costs, both during the construction process and during the operation of the building.

Also, the foam needs careful protection from moisture. Manufacturers claim that the insulation of wooden walls with foam plastic does not absorb water, but this is not so. The polystyrene beads themselves are resistant to moisture, but it can accumulate in the space between them. Freezing water expands. The well-known law of physics does not apply here: water is the only substance that increases in volume with increasing temperature.

As the water expands, the pressure inside the material increases. This will eventually cause the styrofoam to crumble into individual balls in the first or second winter. To replace the external insulation will have to make a lot of effort and spend money.

For all the above reasons, insulation of walls outside a wooden house with foam plastic is not recommended. But you can consider using it for other structures, for example, basement and attic floors. In this case, special attention should be paid to waterproofing. The reason for this recommendation has already been stated.

Extruded polystyrene foam

To perform the insulation of the walls of a wooden house from the outside, you can consider using Penoplex. It is the closest relative of polystyrene, but is devoid of most of its shortcomings.

First of all, the insulation of wooden houses with such material has greater strength. Penoplex is resistant to stress and mechanical damage. The second positive property is moisture resistance. The material is not afraid of moisture. This insulation for walls and ceilings can be used even without vapor barrier and waterproofing.

The benefits can also include:

• high energy efficiency;
• ease of installation;
• ease of processing;
• safety and environmental friendliness.

But the disadvantage again becomes poor air permeability. Without additional ventilation, the greenhouse effect in the house is guaranteed. Read more about the insulation of a wooden house with Penoplex.

It is not recommended to use Penoplex for houses outside, but it will be an ideal option for floors. Such material is not afraid of loads. On top of it, it is enough to make a cement screed with a thickness of 30-50 mm. It can be used both for the floor of the first floor and for the attic floor. Also, very often expanded polystyrene is bought for floor insulation on the ground.

Scheme of floor insulation with Penoplex

Due to the resistance to moisture, insulation can be dispensed with. But for wet rooms (bathroom, bathroom) it is recommended to put waterproofing. Such additional measures will protect the ceiling and insulation from water during various leaks. We recommend that you familiarize yourself with the principles of floor insulation with Penoplex in more detail.

Mineral wool

What kind of insulation is better to protect the walls of the building? The answer here will be unequivocal. For both an old wooden house and a new one, mineral wool will be the best option. It not only allows you to save the beneficial properties of wood, but also smoothes out its shortcomings.

If you insulate the walls of a wooden house from the outside with mineral wool, you can prevent a fire. Most of the materials in this group are non-combustible. This property distinguishes cotton wool from polystyrene and polystyrene foam.

Wall insulation in a wooden house outside with mineral wool conducts air well. When using it, you do not need to resort to additional ventilation measures: with the right choice of finishing material, the walls will continue to “breathe”. But this very finishing needs to be given special attention, otherwise you can ruin everything at the last stage.

The main area of ​​application of the material in a wooden house is walls and roofing. It is strongly not recommended to lay cotton wool in ceilings. It has a fairly low strength and shrinks over time. This will lead to a decrease in thermal insulation characteristics and damage to floor structures. It is possible to insulate the structure of the attic floor with mineral wool. It will also be very effective to insulate the roof with mineral wool.

You can insulate the walls of a wooden house using different types of material:

• Stone (the most common option is basalt). It is produced in plates and has the highest rigidity compared to other types. It is quite convenient to work with this type of insulation. It is safe and easy to cut.

stone wool

• Glass. Is issued in rolls (mats). Its rigidity is not so high. The disadvantages include inconvenience during installation. Glass fibers can cause a lot of inconvenience to workers: they penetrate the lungs and get on the skin, causing severe itching and irritation. Before insulating an old wooden house (or a new one) with such material, you need to prepare a set of protective clothing: a suit, mask, gloves.

glass wool

• Slag. The cheapest and most undesirable option. Thermal insulation of this type is made from industrial waste. Poor-quality cotton wool or a fake will pose real harm to the health and life of the inhabitants of the house, as it may contain hazardous substances. Such a heater for the outer walls of a wooden house should be bought only from trusted responsible suppliers who are responsible for the quality of their products.

slag wool

Vapor barrier and waterproofing

How to properly insulate a wooden house from the outside? It is important to firmly remember one thing: the vapor barrier is laid on the side of warm air, and the waterproofing is on the side of cold air. Both the outer and inner material can be produced in the form of films and membranes. For a building made of wood, it is recommended to choose the latter option. The films practically do not let air through, and the membranes “breathe”.

Arrangement of steam, wind and moisture insulating layers

Before insulating an old wooden house from the outside, it is worth checking the condition of the walls, ceilings and roofs, and if necessary, reinforcing them and protecting them from mold and fungus. A combination of such measures will extend the life of the building. Also, the insulated structure must be cleaned of dirt and dust.

How to insulate a wooden house from the outside: not difficult and not expensive

Proper external thermal insulation of the walls of a new or old wooden house requires strict adherence to technology. We will talk about it in this article.

What is the best way to insulate a wooden house from the outside?

KakPostroit.by > Exterior decoration > How to insulate a wooden house from the outside?

The popularity of houses made of wood is only increasing every year. And for good reason. This is due to the ease and speed of construction work, as well as the excellent thermal insulation properties of the material. However, the latter fact does not at all exclude the expediency of warming, especially in areas with a harsh climate. How to properly insulate a wooden house from the outside and with what? The advantages and disadvantages of popular materials, as well as important nuances of doing this kind of work with your own hands will be revealed further.

Insulation options

Warming a wooden house from the outside has a lot of advantages:

• the dimensions of the interior rooms remain unchanged;
• lack of debris and dust inside the room;
• there is no need to rearrange the furniture or perform any internal work;
• additional protection of the structure from environmental influences;
• for old houses that have lost their attractiveness, insulation is an opportunity to ennoble, transform the appearance of the building.

Note! Improper performance of work on the insulation of a wooden house from the outside can lead to mold, damage and decay of the wooden structure. Therefore, only a competent, comprehensive approach to business guarantees a high-quality, desired result.

Despite the constant discoveries and developments in the field of construction and building materials technologies, 3 options for insulation materials have confidently gained a foothold on the market:

All of them have excellent insulating properties. However, each material has its own characteristics and disadvantages, which are extremely important to consider. A detailed consideration of each material will allow you to decide how best to insulate a wooden house.

Mineral wool, features of insulation

Mineral wool is compressed particles of artificial stone, basalt and slag. It does not support combustion, which is commendable for a log house, and does not undergo deformation. This material has proven itself in construction and is widely used to insulate the walls of a wooden house.

The advantages of mineral wool with confidence include:

• ease of installation;
• environmental friendliness of the material, its harmlessness;
• guarantees additional protection against fire;
• democracy, affordability;
• durability;
• the structure does not deteriorate, does not change under the influence of temperature changes;
• the material has a high melting point, therefore, in terms of fire safety, it is better than many.

Mineral wool also has disadvantages, although there are few of them:

• the need for additional protective equipment (respirator, gloves) for construction work;
• does not protect the surface of the log house from the development of fungus and mold;
• hygroscopic, easily absorbs moisture, so high-quality hydro and vapor barriers are required.

When choosing mineral wool as a heater, consider the following tips:

1. Before warming, be sure to treat the walls of the log house with a special antiseptic solution.
2. Completely exclude the possibility of moisture penetration to the mineral wool. To do this, a layer of vapor barrier is laid, then a heater and a layer of waterproofing.
3. It is necessary to mount the material with a call to half of the previous sheet of material, spaces between the elements are not allowed.
4. Additionally, you can limit the shift of mineral wool using anchors.
5. You can use not only mineral wool, but also its varieties (for example, glass wool).

Styrofoam as a heater

If it is impossible or unwilling to use mineral wool, you can insulate a wooden house with your own hands using foam. Outwardly, it is an accumulation of a large number of air, foam balls of plastic mass. In terms of insulating qualities, polystyrene (expanded polystyrene) is in no way inferior to mineral wool.

The advantages of this material include:

• ease and convenience of installation;
• lightness of the material;
• dense surface that is not exposed to moisture and fungi;
• increased soundproofing qualities;
• resistance to temperature changes and precipitation;
• significant service life.

The main disadvantage of the building material is unnaturalness and low fire resistance.

Warming the walls of a wooden house with polystyrene foam is no more difficult than with mineral wool. Rather, on the contrary, a sheet of material is easily transferred, adjusted to the required dimensions by trimming. The nuances of working with such an insulator include:

1. It is necessary to lay the material end-to-end.
2. To process gaps at the joints of polystyrene sheets, a diffusion membrane is used. It is attached to the surface with a stapler directly to the light.
3. The diffusion membrane must be at least 10 cm wide to ensure complete insulation of the foam joints.
4. Use tape to connect the membrane pieces.
5. Despite the stable ratio of foam to moisture, a waterproofing layer is still necessary.

Note! Many builders are categorically against the use of foam as a heat insulator. Because if the work is not properly organized, it will accelerate the development of the fungus on the walls of the house. To avoid this, be sure to provide a good gap between the structure wall and the vapor barrier to ensure sufficient air ventilation.

Foam insulation (polystyrene)

Penoplex is a colleague of polystyrene. It is also a cellular, honeycomb surface filled with polystyrene balls, but exceeds its predecessor in technical characteristics.

Penoplex allows you to easily insulate a wooden house with your own hands. For this, the heat insulator has a lot of prerequisites:

• increased technical characteristics;
• good surface strength;
• does not rot and does not absorb moisture;
• perfectly retains internal heat;
• does not respond to changes in external temperatures;
• ease of installation;
• environmentally friendly material;
• does not burn;
• enjoy a long service life.

The disadvantages of penoplex are as follows:

1. The cost of the material exceeds the cost of mineral wool or polystyrene.
2. The need for high-quality protection from ultraviolet exposure to sunlight. They destroy the structure of the heat insulator.
3. Sensitive to solvents and similar substances.
4. Easily damaged by rodents.

As for the insulation process, it is identical to foam.

Note! A prerequisite for foam insulation is the presence of a ventilation space between the vapor barrier and the wooden wall.

Log house insulation technology outside

Now consider how to insulate a wooden house from the outside, in stages:

1. Prepare the surface of the walls of the house. To do this, clean them of dirt, and treat them well with a special antiseptic solution or primer.
2. Seal gaps, holes and cracks in the wall with mounting foam. When the foam dries, cut off the remnants with a sharp knife.
3. Wet walls are not suitable for insulation. Wait until the surface is completely dry.
4. To lay the vapor barrier layer, make a crate of wooden slats. The step between the slats should be 1 m. The crate should guarantee the presence of a ventilation space within 20 mm. This is necessary to prevent the accumulation of moisture drops on the tree, followed by decay, damage to the wall surface.
5. Install vapor barrier material. It can be isospan, polyethylene or roofing material. Fix the vapor barrier on the rails, and seal the attachment points with adhesive tape to seal the coating.
6. Make a frame for the heat insulator, also using wooden planks 40 × 100 mm. A heater will be mounted in its grooves. Therefore, in order to achieve maximum joint density, the distance between the laths should be 15 mm less than the width of the sheet of material used. Wooden planks are installed only on the edge.
7. Using the building level, monitor the evenness of the crate to avoid the appearance of bumps, gaps and other shortcomings.
8. Lay the insulation in the resulting grooves, taking into account its individual characteristics.
9. The next stage of the "pie" is the laying of a layer of hydro-windproof membrane. It must be fastened with nails or a construction stapler to a wooden frame. Again, treat the joints with adhesive tape for tightness.
10. The final stage is the installation of decorative trim on the facade of the house. Use siding, lining, brick or other building materials for this purpose.

• Insulation of a wooden house from the outside: how to properly and the better to insulate

  
  Instructions for warming a wooden house outside with various materials. How to make it with your own hands, and the better.

How and with what to insulate a wooden house from the outside - the choice of materials and installation rules

It would seem that the question is quite simple - and the methods have long been worked out, and the choice of thermal insulation products is significant. But this is not about any building, but about a wooden house. Regarding its insulation, there are a number of nuances that cannot be neglected.

It's all about some features of such a building material as wood. First of all, it is its susceptibility to decay, the ability to "breathe" and retain heat well. The last two properties allow you to maintain comfortable conditions in the premises, as a rule, without significant additional costs. For example, for the purchase (and professional installation) of climatic equipment, due to the increased consumption of en / resources (including fuel for the boiler). At least, the indicated devices are not used as intensively in wooden houses as in brick or cellular concrete buildings. So, let's consider in detail how and what is the best way to insulate a wooden house.

Helpful information

To make the technology of work clearer, it should be explained why insulation from the outside for a wooden house is the only right solution. This method of reducing heat loss is the main one for any buildings, as it has a number of advantages. For example, does not reduce the usable area. This is one of the disadvantages of arranging this protective layer from the inside. But for a log house, something else is more relevant.

It's all about the so-called "dew point". The external installation of the insulation takes it outside the perimeter of the house, and condensate forms in the ventilated space. Consequently, in cold weather, the tree does not freeze, and in warm weather, the process of decay does not begin. If the insulation is laid on the walls of the premises, then the “point” shifts inward. As a result, the logs (beams) remain unprotected, and the condensate settles in the thermal insulation material, which initiates the development of mold and fungus not only in it, but also in the rooms.

How to insulate a wooden house

If you delve into the details, then the choice of materials is not so big.

Styrofoam boards

They differ not only in the correct geometry, but also in "rigidity". Therefore, to fix them, it is necessary to carefully align the base. It is still acceptable for a beam, especially if the walls were erected by professionals. And what about logs? In addition, foam plastics do not let in not only moisture, but also air. Therefore, the main attraction of a wooden house - climate control - will be completely leveled.

Spray formulations

Usually polyurethane. There are even more disadvantages, besides, special equipment will be needed. But the companies providing this service (for PU insulation) are silent about another rather significant disadvantage - the low maintainability of the layer. After all, it sticks to the surface on which it is applied. If, in the literal sense, it can still be “picked out” from a brick or concrete goods, then what about the tree? After all, it is quite malleable to mechanical stress, and damage to logs or timber in this case cannot be avoided.

There are other types of insulation for wooden buildings, which are advised to use the authors of some articles. But all the listed materials (chipboard, flax fiber, etc.), taking into account the specifics of the log house and in terms of durability, hardly deserve attention.

Warming the house from the outside - how to do it

Surface cleaning

This is where any repair or finishing work begins. For a wooden house, the initial inspection is especially important. It is necessary to identify all foci of damage to wood, determine their nature, methods and means to eliminate defects.

Processing with special / preparations

For a wooden house, both are equally relevant - flame retardants and antiseptics. Features of their use and formulation are indicated on the packaging. It is clear that it is desirable to do this in positive weather and clear skies.

Installation of a vapor barrier layer

Its main purpose is to ensure the ability of wood to self-regulate the microclimate and at the same time protect the material from direct contact with moisture. There are many varieties of films and membranes on sale. If the first option is chosen, then it must be taken into account that all samples differ in their execution, and therefore, in the specifics of use. The film is cheaper, but the usual modification of polyethylene cannot be used for vapor barrier. It is hermetic, and together with water does not let air through. It is worth considering when choosing products.

Mounting on the outside of a wooden house is quite simple - using a construction stapler (staples). It is only necessary to take into account that the strips must be mounted with a slight "overlap", and the joints must be closed with adhesive tape (adhesive tape).

The construction of the supporting frame

It is also called a crate. What is its peculiarity in relation to a wooden house? The coefficients of thermal expansion of the materials to be bonded should be taken into account. Metal slats are much more convenient for installation, but since the house is made of wood, it is not advisable to use them. Only wooden bars of the appropriate length and section.

The dimensions of the seats (cells of the crate), as well as its design, are selected based on the geometry and design of the insulation. Mineral wool is sold in slabs or rolls, so it is not difficult to draw up a sample laying pattern.

Another nuance concerns fasteners. Self-tapping screws or screws should not be used for fixing elements of the crate. They "tightly" grab the supporting structure, and this should not be. A wooden house “plays” somewhat under the influence of external factors (a feature of the material), therefore, fastening the crate to it is only with nails.

What to consider

The reliable position of the insulation is ensured by the fact that during the laying in place, the samples are slightly compressed. Then, due to their elasticity, they straighten out somewhat, which determines their reliable "hitch" with the slats of the supporting frame. When calculating its parameters, it is necessary to choose the cell sizes so that they are slightly smaller than thermal insulation products. Then you do not need any of their additional fastening on the outside of the house.

Laying insulation material

There is nothing complicated about this, especially if the scheme is drawn up correctly. Mineral wool is well cut with an ordinary knife, they bend, so there will be no problems.

• On problem areas of the walls (complex configuration, slope, etc.), it is worth additionally fixing the thermal insulation with special nails - anchors.
• The gaps at the junction of the insulation to the frame rails are sealed with the same construction tape.
• Installation of thermal insulation is carried out in the direction from the bottom up, in rows.
• In regions with frosty winters, insulation (depending on the thickness of the samples) can also be laid in 2 layers. In this case, the plates for the second are cut so that after installation their joints in the rows do not match. That is, a mount with a slight offset.

Calculator for calculating the amount of insulation

Hydrowind protection layer

Since we are talking about a wooden house and mineral wool, traditional waterproofing is clearly not enough. It is advisable to mount a membrane (or a film of the corresponding modification) on top of the insulation. The order of laying (which side is inside) depends on the version of the product and is indicated in the accompanying documentation.

Using a conventional p / e film will lead to the fact that moisture will begin to accumulate in the insulation. There is nothing to comment here.

Control grille

It is necessary to create the so-called ventilated space. In most cases, it alone is enough to ensure effective removal of liquid due to the natural circulation of air currents.

Details of the counter-lattice are rigidly fixed on the rails of the supporting frame. Their elevation above the latter, as well as what exactly to use as these structural elements, depends on the finishing material of the wooden house. It can be both cutting bars and a metal profile. In this case, thermal expansion is unimportant.

• Warming the walls of the house from the outside is only a partial solution to the problem of reducing heat loss. We must not forget about such parts of it as the basement and the foundation (if it rises above the ground). This is where expanded polystyrene comes in handy, and spraying can be done, given the small coverage area, with your own hands. There are special devices, and they are not so expensive. And although in fact they are one-time use (despite the fact that the manufacturers claim otherwise), given the reasonable price, it is possible to implement such an option for warming outside the lower part of a wooden house.
• When choosing a variety of mineral wool, it is advisable to focus on products of the "eco" category. From all points of view, for houses made of wood - this is the best option.

How and how to insulate a wooden house from the outside - from materials to installation

Do you have a wooden house? Do you want to figure out how and how it is better to insulate it from the outside? This article explains everything in detail, step by step and gives a number of useful recommendations.

Wall insulation from the inside in wooden houses makes them more comfortable and economical. In addition, the good performance of the walls in terms of heat engineering allows you to save on heating. The issue should be approached seriously, since the result will completely depend on the chosen material and compliance with the technology.

Warming from the inside

Thermal insulation of the house from the inside avoids the need for exterior decoration. With this approach, it is possible to preserve the attractive appearance of a building made of timber or rounded logs. But the technology has a number of disadvantages that you should prepare for:

• interiors are protected from the harmful effects of cold, but not walls;
• the useful area of ​​the building is reduced;
• there are certain restrictions on the materials used.

Which heater to choose

What is the best way to insulate a house? It is worth starting from the material of the walls. The tree has gained well-deserved popularity due to the fact that it is able to "breathe". Wood is well breathable, while providing excellent ventilation in the premises.

To preserve the useful properties to the fullest, when working from the inside with your own hands, you need to use materials that are similar in breathability to wood. To insulate the house, it is better to abandon such heat insulators as:

• Styrofoam;
• extruded polystyrene foam (or more simply “Penoplex”);
• penoizol.

They are highly airtight, so they can create a greenhouse effect in the building. This will require an expensive forced ventilation device or the installation of air conditioners.

The best material for thermal insulation will be mineral wool.

Its advantages include:

• high efficiency;
• the ability to pass air without interfering with natural ventilation;
• safety for human health and the environment;
• incombustibility;
• ease of installation;
• availability;
• low cost.

But when using cotton wool, it is worth remembering its shortcomings. The material absorbs moisture well, while ceasing to perform its main function. To avoid getting wet, you should also purchase a vapor barrier and wind-waterproofing.

Scheme of layers for insulation with mineral wool

There are several varieties of mineral wool. The best option would be basalt (stone) insulation in slabs. You can also choose glass wool, which is available in the form of mats twisted into a roll. The second option can cause difficulties during installation. The material is highly prickly, and the particles, getting into the lungs or on the skin, cause itching. To avoid unpleasant consequences, all work with glass wool is carried out in special clothing and masks.

The most undesirable, but inexpensive option would be slag wool. But, insulating your home, it is better not to save. Cotton wool is made from industrial waste. Manufacturers are responsible for safety, but it is not always possible to check from which slags the insulation is made. You can easily come across low-quality material or a fake, with which the insulation of a wooden house from the inside will be dangerous to health and life.

Preparatory stage

Before insulating a wooden house from the inside, you will need to prepare the walls. This is especially true if it is necessary to insulate an old wooden house. In this case, the material that was used for the caulking has managed to clot. The main task at this stage will be the elimination of cracks - sources of drafts, cold and moisture.

Work begins with cleaning the base. You will need to remove the dust and dirt that has accumulated on the walls. Before insulating an old house, it is worth checking the strength of the wood. It should not be damaged by various pests. Otherwise, it is better to strengthen the walls.

To prevent problems with insects and microorganisms in the future, the surface is treated with antiseptic compounds. You can also perform the treatment with fire retardants, they increase the resistance of the material to fire.

Treatment with antiseptics will protect the wood from decay

Wood shrinks over time. Because of this, cracks may appear in the walls. Before starting work on insulation, it is worth doing. Currently, jute is most often used for these purposes. For large gaps, it would be wise to purchase tape tow. The material is hammered between logs or timber using a chisel.

Caulking will protect the walls from blowing and become an additional heat insulator

It is necessary to perform work until the material ceases to fit into the space and begins to hang out. High-quality caulking is the key to a warm home.

Wind waterproofing of walls

Mineral wool is afraid of moisture. Before you insulate the walls in a wooden house, you should take care of protecting the insulation. On the outside of the mineral wool, a layer of wind-waterproofing is fixed. It prevents weathering and penetration of atmospheric moisture. There are several types of suitable materials, but a vapor diffusion membrane is the best option.

This modern material reliably protects against water, but does not interfere with the movement of air and steam. This allows you to maintain the ability of the walls to breathe, as well as ensure the removal of moisture from the insulation.

Waterproofing is attached to the walls with a construction stapler. The joints of the canvases are made with an overlap of at least 10 cm and glued with adhesive tape or a special tape.

Insulation installation

Internal wall insulation is carried out according to the frame. It can be made of wood from a metal profile. The easiest way to insulate a building made of wood is to use wood for the frame. It is important to correctly select the geometric dimensions of the frame:

• The pitch of the racks is selected taking into account the width of the insulation. It should be about 2 cm less than the width of the mats or slabs. This is necessary for a tight fit of the material. For mineral wool, such a step of racks is most often used so that a distance of 58 cm remains between them in the light.
• The frame overhang must take into account the thickness of the insulation and the required ventilation gap. It is needed to remove condensate from the surface and allows you to keep the material dry. The thickness of the ventilation gap is usually taken equal to 3-5 cm.

The installation of plates in the walls should be carried out with an interference fit - then it will not begin to slide over time

Mineral wool is laid between the racks of the crate. With the right choice of the step of the latter, the heat insulator will be held due to friction. For additional fixing, you can use special plastic dowels, they are usually sold together with insulation.

vapor barrier

How to properly insulate the walls of a wooden house from the inside? It is important not only to choose the right insulation, but also to protect it from all types of moisture. Indoor spaces are characterized by sufficiently high humidity, water in the form of steam can easily reach the mineral wool and reduce its effectiveness.

Vapor barrier - a mandatory layer when using mineral wool

Internal wall insulation implies a mandatory presence. It is mounted on top of the heater. A good option for protection is vapor barrier membranes.

They are more expensive than films, but they do not interfere with the movement of air through the walls. Membranes will become a more modern and efficient option.
Insulation of a wooden wall from the inside with their help is carried out according to the manufacturer's instructions. Mounting method may vary for different types.

Finishing

The insulation of the walls of a wooden house is completed with a fine finish. For these purposes, you can use a variety of options. But when choosing a material, it is worth remembering about ventilation. The finishing layer should not impede the movement of air, otherwise the entire previous choice of materials is useless.

Lining for interior lining - a simple, inexpensive and environmentally friendly option

Insulation thickness

Wall insulation in wooden houses from the inside should begin with the calculation of the thickness of the heat insulator. Only a professional can perform detailed calculations. With independent construction, you can use special programs. For example, the Teremok program. It is quite simple and is freely available. There is both an online version and a PC app.

On average, mineral wool 80-100 mm thick is used for walls. But it all depends on the climatic region.
Before insulating your own wooden house from the inside, you should carefully study the information on the topic.

And do not forget that from the point of view of heat engineering, it is more correct.

Competent performance of work is the key to durability and comfort.

Wooden buildings retain heat much better than concrete or brick ones. But they also need extra insulation. Everyone knows that wooden buildings eventually give shrinkage. At the corners and at the seams of houses, cracks and crevices form, through which cold from the street enters the house.

To prevent all this, it is necessary to insulate the outside, how and with what to do it - read below. It is also worth noting that proper thermal insulation will help home owners save on heating. But in order to maintain the desired indoor climate and extend the life of the tree, it is necessary to choose the right materials for insulation.

Choosing wall insulation, keep in mind that any tree absorbs moisture well. Therefore, it must be processed impregnations. In order for the room to have a favorable microclimate, it is necessary to take care of good ventilation in the room.

If the air exchange in the room is disturbed, then this will lead to the swelling of the tree and the formation of fungi and mold on it. To prevent the above problems, you must:

1. Insulate only dry walls.
2. Choose vapor-permeable thermal insulation materials.
3. Make and waterproof walls.
4. Leave an air gap between the insulation and the finish.

Before you start warming, prepare well all work surfaces. They should be free of mold and dirt. If they need repair, do it in advance. And check that there are no harmful insects on the tree.

Attention: if you plan to paint wood in the future, then the sealant and paint must be vapor-permeable.

Also, before warming the house, you must carefully read wall composition.

Keep in mind that the technology of warming a house made of wood provides for the presence of:

• vapor barrier;
• insulation;
• waterproofing;
• exterior cladding (read:).

It is hydro and vapor barrier that will protect the tree from excess moisture.

How to insulate a wooden house?

An unusually large range of heaters is provided on the modern construction market. But keep in mind, not all of them are vapor permeable. As a rule, for wooden buildings use:

• extruded ;
• polyurethane foam.

You can choose what kind of insulation it is better to insulate a wooden house from the outside by reading the characteristics of each of them below.

How to properly insulate with mineral wool

Mineral wool is an excellent choice. If you opted for this material, then you will not need special skills and abilities to apply. Since the whole workflow will be quite easy and simple.

To perform quality work, you only need to stock up on free time, the necessary tools and consumables. Before work, carefully prepare the surface and properly calculate the right amount consumable.

note

Wooden houses are subject to shrinkage. Therefore, they need to be insulated only a few years after the construction.

Considering specifications mineral wool is worth highlighting:

• incombustibility of the material;
• no deformation;
• ease of installation;
• harmlessness and environmental friendliness;
• affordable cost;
• long service life.

If you have chosen mineral wool to insulate your home, please note that this material:

• requires additional protective equipment during work (respirator, gloves, glasses);
• absorbs moisture, so you must first make high-quality hydro and vapor barrier;
• will not protect the tree from the formation of mold and fungi. Therefore, the walls will have to be additionally treated with special antiseptics.

When choosing mineral wool, you need to consider that it happens:

1. Basalt.
2. Glass.
3. Slag.

Each individual option has its own characteristics. Basalt cotton has a high degree of rigidity. This material is available in slabs, it is easy to cut with any tools and it is a pleasure to work with it.

Concerning glass cotton wool, it is produced in rolls. It is not always convenient to work with it, as glass fibers strongly irritate the skin.

slag cotton wool is the most inexpensive. If you choose this particular material, carefully consider the choice of the manufacturer. Since unscrupulous companies can use raw materials harmful to people in the manufacture of their products.

The benefits of foam

You can also insulate your home with foam. This material also has a lot of advantages. The main ones include:

• ease and simplicity in work;
• light weight of the material;
• excellent heat and sound insulation qualities;
• resistance to negative factors;
• long service life.

On the surface of the foam will not form no mold or fungus. It is fireproof, harmless and perfectly copes with sudden changes in temperature and high humidity.

Important: this material is laid butt to butt. Make sure your home is well ventilated to prevent mold from growing on the walls.

Extruded polystyrene foam and its positive qualities

Expanded polystyrene is also in great demand and popular for home insulation. This material is:

• durable and reliable;
• durable;
• easy to work;
• environmentally friendly;
• affordable in terms of price.

Continuing to list the positive aspects of extruded polystyrene foam, it is worth highlighting such technical qualities as: resistance to burning, excellent heat and sound insulation qualities, high specifications. Expanded polystyrene is also resistant to mechanical damage and heavy loads.

note

Expanded polystyrene must be protected from ultraviolet rays. It can also be damaged by rodents.

But the main distinguishing feature of the material is its moisture resistance. Thanks to this, when warming, you can not even do steam and waterproofing.

How to insulate with polyurethane foam?

Polyurethane foam also has a wide range of applications in the external insulation of buildings. This material has benefits, as:

• low thermal conductivity;
• light weight;
• high thermal insulation qualities;
• resistance to mechanical deformations and heavy loads;
• resistance to the appearance of fungi and mold;
• durability;
• environmental friendliness.

This material is completely non-toxic and does not harm human health in any way. It does not burn under any circumstances and is universal. It is used not only for wall insulation, but also for attics and other similar premises.

Calculation of the thickness of the insulation

For effective insulation of a wooden house, it is necessary to correctly calculate heat insulator thickness.

Otherwise, an incorrectly selected thickness of the material will lead to condensation and dampness appearing on the walls of the building.

And too large a heat insulator will lead to a violation of the air circulation inside the room. Each manufacturer indicates the necessary information for the consumer on their packaging.

note: the lower the thermal resistance of the wall, the larger the layer of heat insulator should be.

The main ways to insulate a wooden house from the outside

Technology Well

This technology can be called the most effective, but rather labor intensive and costly. It is most often used for brick buildings. This method consists in the fact that the heat insulator is attached to the facade in any convenient way, and a wall is attached to it.

This technique is used in places with harsh climatic conditions, where the air temperature drops below 50 degrees. Recently, this method has been used quite rarely, but it can also be used to insulate a wooden house.

Wet adhesive technology

This technology is most suitable for houses built from round logs and timber. For this, it is necessary to use external plaster in several layers.

This method is carried out in sequences:

1. We carry out preparatory work.
2. We fix the heater.
3. We apply an adhesive mixture to the heat insulator and fasten the reinforcing mesh.
4. We plaster the surface several times.
5. We apply the finishing decorative layer.

To benefits such a method is worth mentioning.
