Insulation of walls from the inside of a wooden house in various ways. Instructions for insulating the walls of a wooden house from the inside How to insulate a wooden house from the inside

Discuss the insulation of frame wooden houses we will not be here - this is generally a separate conversation, there is a different technology and we will talk about them in other articles.

Why it is not desirable to do thermal insulation of walls from the inside, and what consequences may arise, I have already described in one of the previous articles.

Here we will talk exclusively about the features of insulation from the inside, related to wooden houses.

In principle, there are not so many features, basically it is necessary to adhere to the basic rules of wall insulation from the inside, the main of which says that no wall insulation from the inside can replace high-quality insulation of the house from the outside. But if there are no options, then it is necessary to adhere to a certain technology.

Preparing the wall of a wooden house for insulation

This stage is very important, since after insulation, access to the timber from the inside will be very limited, and in order to fix something, it will be necessary to completely dismantle the insulation.

And so, first of all, it is necessary to clean the walls from the inside from dust, dirt, various delaminations, etc.

After sealing the cracks and holes that have appeared.

Deal with electrical wiring if you have wires running along the walls. If the house is old, it would be better to check all the electrical wiring, repair if necessary, if it is new, then carry out installation, not forgetting about electrical safety in wooden houses.

Vapor barrier for insulation

Before installing the insulation, it is necessary to prepare a vapor barrier. It is necessary to protect the insulation from moisture on the walls, which, after insulation wooden walls home from the inside will be inevitable. In turn, the more moisture inside the insulation, the less good it will be.

At vapor barrier film there is also a negative effect - the creation of a thermos in the room. The walls practically cease to "breathe", the humidity, as a rule, rises. Only good ventilation can save you from this. Without ventilation, wall insulation from the inside should not be started, because over time you will get the feeling that you live in a plastic bag, and the walls will start to sweat and get wet, and as a result, fungus and mold will appear, which will have a very detrimental effect on wooden walls and the health of the people living in the house.

Vapor barrier can be made with a special membrane film, which will do its job much better and more correctly, but it also costs much more.

Installation of insulation on a cotton basis

Typically, installation mineral wool produced using crates, as this is the most suitable option due to the characteristics of this type of insulation.

On the wall, on top of the vapor barrier, a wooden crate is mounted (it is not advisable to use a metal one, since the metal has a very high thermal conductivity).

Then a heater is laid between the slats. The most commonly used material for wall cladding from the inside is drywall. It is screwed, as a rule, directly to the crate.

Installation of polystyrene insulation

Styrofoam is the cheapest and most practical insulation today. Expanded polystyrene as an external insulation is used very often, mainly because of its cheapness and low thermal conductivity.

But despite this, it is the least suitable for warming the house from the inside.

There are several reasons for this:

release of toxic substances (the higher the temperature, the more)
airtight
over time, rodents may appear in it

Installation of insulation "Ecowool"

The characteristics of ecowool are much more favorable for insulating the walls of a wooden house from the inside:

breathable material
there is some protection against fungi and mold
due to the passage of air through itself, it does not allow the walls to store increased moisture.

Common mistakes when insulating wooden walls from the inside with your own hands

Many people think that the more insulation when warming from the inside, the better. I assure you that this is a myth. If there is too much insulation on the walls from the inside, the dew point can move into the insulation itself, and if it is on a cotton basis, then its thermal insulation will decrease significantly, and the insulation itself will not live in dampness for a long time.
Some insulate the wooden wall of the house on both sides, and this will have a very detrimental effect on the wall itself. The reason for this is the vapor barrier of the insulation, which will not allow the wall to dry out, and over time, fungi, mold and rot will appear there, which will destroy your wooden structure much faster than you think.

If you have the opportunity to insulate a wooden house from the outside, then insulate without hesitation, wall insulation from the inside is fundamentally wrong and it is necessary to resort to this type of insulation only in extreme cases when there are no other options.

Insulate walls, both from the outside and from the inside, preferably in warm time years when the wall is at its dryest.
If you have any cladding on the outside of the house, you need to make sure that between the cladding and wooden wall There are products that will allow your wall to dry out somehow.
Before installing the insulation from the inside, carefully treat the wooden walls of the house, because after the insulation in the wall there will be a microclimate of increased danger for the wood and excess impregnation will not hurt.
If you are going to sheathe the walls from the inside with drywall, then when installing the crate, take into account the dimensions so that you do not have to build additional fasteners for drywall.
Do not use polystyrene for insulation from the inside, do not fall for its cheapness and excellent qualities as a heater. It is not suitable for interior work.

How to choose a heating method

This issue must be resolved in the first place - a method of insulation. To do effective insulation housing, you should understand the process itself step by step and its results, after which you should already make a decision. In the old days, in order to make the house warm, they didn’t bother much, and there were no opportunities commensurate with the current ones - therefore, they simply increased the thickness of the walls. Nowadays, modern heat-insulating materials, which have appeared in a huge variety on the market, have become available to everyone, so there is no need to increase the thickness of the walls. But it is necessary to study the pros and cons of new materials and technologies.

Of those who are desperate for such a step as thermal insulation from the inside, few people seriously imagine the difficulties of such an option.

Light in weight and installation, materials with high frost resistance and low thermal conductivity are already being used with might and main not only in the construction of new structures, but also in the reconstruction of existing ones. External insulation of the building with the help of modern technological materials allows not only to minimize heat losses, but also to protect the building from exposure to ultraviolet radiation, precipitation and temperature changes "overboard", which means it will save money on heating and significantly extend the service life. Of course, this is subject to the quality of the work.

Problems such as cold bridging, wall wetting, and fungal infections can be the result of technology failure. As a result, the effect of all the work carried out will inevitably decrease, as well as the service life of both heat-insulating materials and the building as a whole will decrease, which entails new costs.

How heat loss occurs in a wooden house

The walls of a wooden house have natural gaps and crevices that need to be sealed.

The process has a certain algorithm. In general, the tree itself is an excellent heat-insulating material. Walls made of wood, due to its natural structure, “breathe” freely, keeping heat perfectly and creating the most favorable microclimate for people in the home. And yet, heat escapes - through junctions, interventional cracks, as well as through corners, cuts, doors and windows. In addition, over time, materials shrink naturally under the wagging of various, incl. weather factors. Additional gaps and cracks are formed. So the natural mobility of a tree, being its advantage, turns into a disadvantage when it comes to tightness. So there is a need for thermal insulation of all fistulas that have arisen.

If we still warm from the inside

Despite the obvious fact that technically it is usually easier for us to insulate a room from the inside, this option has not received wide distribution. There are several well-reasoned reasons for this. And the reduction of the area is not the worst thing here.

What are the points to consider

The walls insulated inside do not really warm up, and temperature drops lead to a situation where, due to the effect of a temperature difference, the dew point moves into the heat-insulating layers, i.e. into the insulation, as a result of which the room becomes damp and sometimes water vapor condensate even settles on the walls, which can provoke a fungus that is detrimental to a wooden house, mold will appear. A vapor barrier with a film helps to partially save the situation, but in this case, so that you don’t get the feeling that you live in a plastic bag, you need to take care of effective forced ventilation in room.
You can avoid undesirable consequences if you significantly increase the thickness of the insulation, which usually causes resistance from the owners of the house, because the living area is noticeably reduced due to this.

Scheme of internal insulation

Warming the house from the inside requires a certain sequence of steps. On the diagram:
1. Vapor barrier system;
2. Thermal insulation;
3. Waterproofing;
4. Clapboard lining.

Where to begin

The first duty before insulating a wooden house, whether external or internal, is to determine what kind of wood the structure is made of. Different wood has different thermal insulation characteristics, which can cause different costs for insulation. It is also important to find and eliminate obvious flaws such as cracks, cracks in logs, defects in insulation stuffing.

After identifying the shortcomings and determining the range of work, they begin to insulate the walls. If there is not enough external insulation, a combined option is often chosen.

From the inside, the walls are insulated, as a rule, in the warm season - in the spring and summer. A freshly built house is insulated after its final shrinkage, i.e. one year after completion of construction. Particular attention should be paid to window structures and doors - a lot of heat leaves the room through them.

Material Requirements

Thermal performance and more

They insulate a wooden house from the inside, as a rule, now with the help of modern synthetic insulation. The main requirements for them are simple: fire resistance and high thermal insulation qualities.

Ecowool

One of the most popular materials in recent years has become the so-called ecowool. The material is sprayed with an integral heat-insulating layer, which, tightly adjoining the logs, timber, perfectly fills all existing voids and cracks, preventing possible blowing through of the walls. Having warmed with ecowool, you can completely do without additional caulking of a log house.

The structure of ecowool is such that internal moisture from the room can relatively unhindered between the fibers, without degrading the thermal insulation properties of the system. At the same time, the interfiber spaces remain dry and excess water vapor does not condense on the surface of the walls. The fact that moisture does not accumulate in ecowool, plus mineral antiseptics in its composition, exclude mold and fungal infection on the walls of the room. Ecowool is successfully used for insulation both outside and inside. Its main trump card is that the house retains the ability to "breathe" freely.
Ecowool can be applied professionally with special tools, but you can also do it manually. Look at this video topic:

Basalt wool, glass wool

The use of other types of mineral wool products, such as basalt wool or glass wool, seems to be also designed to solve the same thermal insulation problems, which they successfully cope with. The thermal insulation performance of these materials is also not bad, but using them in internal insulation can be more difficult to deal with such a problem as moisture getting inside the insulation, and this significantly worsens the thermal insulation qualities of the material. In this case, you can not do without a vapor barrier film as a water seal to ensure internal ventilation in order to eliminate excessive moisture.

Styrofoam

Insulation with foam (polystyrene foam) plates is also common. The undoubted advantages of extruded polystyrene foam are its elasticity and lightness. The good heat and sound insulation and sound insulation qualities of expanded polystyrene allow the use of fairly thin plates, i.e. the process does not affect the usable area of \u200b\u200bthe room. And what is important, polystyrene foam insulation technologies are constantly improving, improving its characteristics.

Intra-wall insulation

Wooden walls are sometimes insulated using the so-called intra-wall insulation. This requires special technology. For insulation inside the wall, it is necessary to use insulation that is resistant to deformation. These are lnovatin, linen and hemp tow. Naturally, this method is only possible for initial stage construction. Insulation is laid in the intra-wall spaces, i.e. between two walls. The most acceptable method of insulation is recognized as "warm" plaster, which has good heat-insulating qualities. How the work is done is described below.

The surface is prepared first. If there are remains of plaster on the surface of the walls, it must be removed. A special frame of reinforcement is fixed to the walls - this is the basis for a new layer. A metal mesh 5 × 5 cm is attached to this frame. The actual plastering of the walls is carried out in 3 stages:

Application on walls by spraying mortar to fill gaps and voids.
Then the primer is applied, with its help the surface of the walls is leveled. This layer of plaster is thicker than the previous one.
Finishing layer - covering, when a fine finish is performed with fine, clean, sifted sand.

Does your wooden house require insulation? But you don't know how to do it right? Then the following information will definitely come in handy. It will be about. Although I would like to note that this method is not used as often as outdoor installation insulation. Why is this method considered less popular?

Modern thermal insulation materials have high technical specifications: light weight, flexibility, excellent ability to maintain indoor microclimate.

There are several good reasons: first, internal option insulation slightly reduces living space; secondly, by performing the installation of a heater on your own, due to inexperience, you can get a violation of the microclimate due to high humidity air. That is why it is best if the insulation of a wooden house from the inside occurs after consultation with specialists or professional builders. They will tell you how to insulate a wooden house inside competently, quickly and correctly.

Please note that the method of internal insulation is fundamentally different from the installation of insulation outside the house.

Causes of a cold snap in the house and the procedure for thermal insulation work

Usually houses built of wood are particularly comfortable: they are cool in summer and warm in winter. Most often, a cold snap in a wooden house can be caused by 2 main reasons. It:

poor-quality or improperly mounted outer heat-insulating layer;
the appearance of cracks in the walls of the house as a result of improper installation, or drying out.

After the reasons for the cold in a wooden house have become clear, you can proceed to familiarize yourself with the list of upcoming work aimed at its internal insulation.

This process will take place in several stages:

First you need to prepare the surfaces.
Then caulk all existing gaps.
Arrange a layer of vapor barrier.
Mount the crate.
Lay a layer of thermal insulation.
Arrange ventilation system.
Next comes the turn finishing works.

And now about all these stages in more detail.

Work on preparing the surface for insulation

The first stage of work on insulation involves the preliminary preparation of surfaces.

When working on laying heat-insulating material, it is necessary to protect the respiratory and vision organs from the ingress of fine dust and other substances.

To begin with, clean all surfaces of the walls from dirt and dust. And then you can proceed to the careful processing of wooden walls with the help of a special composition that protects the tree from insect reproduction. It is very good if the composition you have chosen will additionally perform a function that prevents the process of decay of wooden surfaces, and protect it not only from moisture, but also from the risk of fire.

And yet, at the same stage, it is necessary to take care of the safety of electrical wiring. If there is an option for its surface location, then it must be separated from the wall. Close up the gaps

Having done all the above procedures, you can proceed to the second stage of warming. It provides for the implementation of work to eliminate existing gaps. They need to be carefully sealed. Many people know that after a house is built from a bar, it is necessary to carry out an additional procedure to eliminate gaps, after about 1 year.

Naturally, this is done if the house remained uninhabited. During the operation of the premises, re-caulking of cracks can be carried out later, after about 3 years. What is the best way to fill gaps? Usually, a material such as jute fiber is used for these purposes.

From the tools you will need a chisel, preferably wide and rather thin. For especially large slots, a tape tow is used, which, before being placed in the gap, is twisted in the form of a roller. It is necessary to fill the slots until the material used can no longer be placed in them.

Vapor barrier layer: nuances

Cork insulation retains heat very well and lends itself well to processing.

The presence of a vapor barrier in a wooden house is very important, since as a result of insulation, the wall is blocked between 2 heat-insulating layers. In this case, the degree of humidity in the room increases, since the walls arranged in this way are not capable of breathing. What to do in this case? Saves quality ventilation system, only with its help is it possible effective fight with humidity. If you do not allow dampness on the walls, then you will avoid the process of wood decay.

Simply put, you need to equip a high-quality vapor barrier. It is performed using a special film, which is placed on the surface of the wall of its rough side towards the wooden surface.

Sheathing and thermal insulation layer

You can mount the crate layer on the walls using a wooden beam. It is also allowed to use a metal profile, but only in the case of subsequent sheathing with moisture-resistant plasterboard sheets.

Scheme of wall insulation: 1 - outer skin (lining); 2 - polyethylene; 3- OSB board; 4, 6 - vapor barrier layer; 5 - thermal insulation layer (mineral wool); 7 - ventilation gap; 8 - inner lining.

In order for the corners of the crate to be even and correct, it is necessary to take care of the preparation of the corner posts in advance. To do this, make measurements of the height of the room and, in accordance with this value, cut the timber. The cross section of the beam used for these purposes should be 50 × 100 mm.

As a result of these manipulations, you should get a stand that resembles the letter “G” in its outline. Each of the corners of the room should be equipped with such a rack. When mounting, do not forget to check the verticality of their location.

Now you can proceed with the installation of vertical bars in increments of about 0.5 m. The bar should have a cross section of 50 × 50 mm. Do not forget that all wooden parts of the crate must be pre-treated with a protective compound against decay and fire.

After the crate is completed, you can proceed with the installation of the heat-insulating layer. For these purposes, a material such as mineral wool is well suited. After you have unrolled the roll of material, you need to cut it according to the desired height value. And the width of the heat-insulating layer should be 2 cm greater than the distance between the two vertical bars.

Having placed a strip of a heat-insulating layer between the bars, you need to fix it on the wall with anchors. Please note that anchors with large round caps are used. A second layer of insulation is fixed to the surface of the bars. Vapor barrier, or rather the film used for its device, will help to avoid dampness, and will also prevent small particles of mineral wool from getting into the air. The vapor barrier layer is fastened to the bars using a construction stapler.

Warming a wooden house from the inside is advisable, unless the owner wants to spoil the natural beauty of the natural material from the outside.

It is a pity to close a log house or a facade from a bar to others finishing material, and in this case it is necessary to insulate the walls from the inside.

Internal work includes insulation of walls, floors, ceilings, taking into account the number of storeys and the attic, and the roof.

For warming the house from the inside, they are only suitable for environmentally friendly safe materials to keep indoor climate healthy. Therefore, foam is not included in the list of recommended heaters.

It is allowed to use a safer penofol, as well as a universal material for the insulation of any buildings and structures - mineral wool.

Benefits of insulating a wooden house from the inside

The main advantage has already been mentioned above.

This is an opportunity to leave the facade of the house in its natural form. In addition, the floors inside the house can be insulated, which is very important for maintaining a healthy indoor climate.

Why is it impossible to insulate a wooden house from the inside?

Of course, you can do this, but external insulation has a number of advantages over internal insulation.

Experts advise using this method of insulation in isolated cases, when really external insulation is impossible.

This is due to a number of shortcomings, which should be mentioned in more detail.

The main disadvantage of internal thermal insulation in a wooden house is the displacement of the dew point deep into the wall. This will further lead to the formation of mold there and rotting of the tree.

Among other shortcomings, the following are important:

lack of natural ventilation of the walls;
violation of the microclimate in the premises;
reduction of usable area of the house.

In addition, none of the insulation, except for jute and felt, can be considered 100% environmentally friendly.

Therefore, it is better to insulate the house from the outside. But if this is not possible, it is necessary to choose the most suitable materials for internal insulation.

How can you insulate a wooden house from the inside?

warm seam

Special sealant for log cabins. It is used indoors to insulate the seams between the logs on the facade and ceiling.

Insulation of walls from the inside of a wooden house in various ways

"Warm seam" for insulation inside a wooden house

To maintain complete environmental friendliness, you can replace the sealants with jute, felt or linen tape and caulk the seams with them.

The cost of caulking seams inside the house is from 120 to 250 rubles per linear meter.

It's quite affordable price even for families with a small budget. Therefore, it is recommended to invite specialists to insulate the log house, only they can guarantee the high quality of work.

Mineral wool

Universal insulation, which is most often used outside. Affordable cost and high thermal insulation performance make this material the most popular among developers.

The insulation technology is the same for walls and ceilings.

Positive properties of mineral wool:

high environmental friendliness, especially in modern materials, where formaldehyde is replaced by safer components;
affordable cost - the material is considered the cheapest option for insulation inside a wooden house;
good thermal and sound insulation performance;
incombustibility;
durability - the material does not rot, is not susceptible to fungal diseases;
good indicators of vapor tightness, which, by the way, is both an advantage and a disadvantage.

The negative properties include:

the same vapor impermeability, due to which an unfavorable microclimate for human lungs can be created indoors;
shrinkage when wet;
the need to sheathe the walls with facial material (create a false wall).

Features of mineral wool insulation of walls and ceilings of a wooden house

Unlike external insulation, inside the material is glued directly to the wall, then it is sheathed with a vapor barrier.

It is best to use a special vapor barrier that allows air from the room to pass outside.

This will create additional natural ventilation insulation. Even if wet, the cotton wool can dry out due to the permeability of the vapor barrier.

A crate, timber or metal profile is installed on the vapor barrier (it is also possible under it), on which it is already attached facing material, drywall, board, lining, timber imitation and so on.

Styrofoam

Polymer material based on foam, but without chemically harmful components.

Suitable for insulation inside a wooden house.

In the photo - extruded polystyrene foam "Penoplex"

The advantages include good thermal insulation properties, low weight, durability and moisture resistance.

When choosing this material, such concepts as foamed and extruded polystyrene foam may occur.

In fact, this is the same material, the only difference is in the methods of its manufacture.

The main features of polystyrene foam insulation are the need for careful leveling of the surface and sealing of the seams between the sheets. Old boards must be cleaned of bumps and roughness, and the material is not suitable for a log house from a bar at all.

The joints between the sheets of material are foamed and cleaned after the foam dries.

Just like mineral wool, expanded polystyrene is suitable for insulating not only walls, but also ceilings.

polyurethane foam

The material of the future, which is applied in liquid form with a special apparatus. For insulation with polyurethane foam, it is necessary to mount a frame, which is filled with foam under pressure. It quickly hardens and forms a monolithic protective layer insulation.

Polyurethane foam spraying

Polyurethane foam will reliably protect the house not only from cold and external noise, but will also provide additional guarantees of safety in case of fire.

The disadvantages include the complexity of finishing work after insulation with this material.

It needs to be plastered using a special mesh.

Floor insulation in a wooden house

In addition to the listed methods of insulation, which, as an option, are also suitable for floors, there are several more.

Warm floor

"Heat floor" system, using IR film, expensive pleasure, but on this moment is the most optimal energy-saving option, which, moreover, creates a special coziness and comfort.

Backfill and fill floors

Expanded clay insulation and concrete pouring are relevant for the floors of the first and basement floors.

The advantages include good thermal insulation properties and affordable cost of materials.

There are also options for water and electric floors:

Before starting work on internal insulation, it is recommended to consult with specialists. Perhaps there is a way to insulate the exterior of the facade, and then only work on the insulation of floors will remain inside.

The process of heating the walls from the inside of a wooden house. Materials, tools and costs

Wooden houses are often insulated from the inside, so as not to spoil the facade and not overlap the beauty of the natural material with the outdoor decor.

A new building built of logs or logs will bake and will not initially get cold or warm, as the logs themselves are good heaters.

But after a year and a half, the best knife dissolves, cracks appear, and the house becomes cold.

How to insulate a wooden house from the inside?

Internal insulation requires careful preparatory work for cleaning logs from mold and decay. The least control can cause further rot and failure of the façade.

If the house is new, logs or wood are usually already treated with special rot preparations.

How to properly insulate a wooden house in the interior?

When overhaul and heating the walls of an old house, it is necessary to clean them from colors or old backgrounds to a “live” panel.

Heating occurs according to the scheme:

wall cleaning;
wood treatment with antiseptics;
dew point detection;
vapor barrier laying;
laying of heat-insulating material;
exterior finish.

Depending on the material used outer surface is immediately decorative or intermediate - for example, drywall boards, which are then painted or tapped.

What materials are needed for internal wall insulation

For complete, technically correct thermal insulation, you will need:

antiseptic for wood;
vapor barrier film;
bar or metal profile for the box;
direct heater;
material for outdoor decoration.

For outdoor processing, the most popular drywall, the optimal combination of price and comfort when working with it, this material is becoming the most popular among finishes.

In addition, it has a negative combustibility, which is important for a wooden structure.

Learn more about the internal processing of gypsum.

Manufacturers building materials and building materials as a heater offer various modern materials, including expanded polystyrene and OSB (oriented particle board).

In photodirectional chipboard for internal insulation

Expanded polystyrene is a type of foam produced by special technology, convenient and inexpensive universal insulation (see

also on external insulation with expanded polystyrene).

The tool will require a drill or screwdriver, a stapler to fix vapors, tape and level measurements.

The process of heating the walls from the inside of a wooden house

First, the walls are cleaned (damaged parts of the tree are removed), then the walls must be treated with an environmentally friendly antiseptic.

In specialized stores, their choice is sufficient, the average order price is 1000-1500 rubles per 10 liters.

This range is sufficient for processing 100 square meters of surface.

After processing, you must calculate the dew point according to a special program, and according to these calculations, indicate your location on the wall after installing the fan.

Then you need to install a vapor barrier.

This must be done - the steam lock protects the wooden facade from condensation that occurs when hot and cold air come into contact.

For vapor barrier insulation, non-perforated foil is used, which is available in rolls, especially in the case of vapor jet insulation.

The film is attached to the wall with a stapler.

Then a strip is formed along the level with a distance equal to the width of the insulating sheet. Then thermal insulation firmly inserted between the vertical profile.

The last stage is the fixation of gypsum boards.

This insulation will help to significantly reduce the cost of heating your home in winter and cool it in summer.

How much does it cost to invite a team of end players?

In each region, their prices, mainly end caps, are per square meter of each layer.

But if you average the cost square meter internal wall insulation is about 500-600 rubles.

It's not much if you think the experts will do a good job and keep the house warm for many years without any additional repairs.

How to attach a heater to a wooden wall

The connection of the heater to the wooden wall can be carried out when the structure is in operation and at the stage of completion of the façade.

Both options are acceptable, the main thing is to choose the right heating material and work in accordance with the installation technology.

Mineral wool for wood wall insulation

The easiest and most affordable option for heating a wood facade is to use mineral wool and materials based on this.

The advantage of such materials is the excellent vapor permeability and breathability performance and their ability to remove excessive moisture from the walls.

To properly mount heaters on a wooden wall, it is important to follow expert advice or have some experience in a similar job.

You will need the following materials and tools to complete the installation:

wooden blocks for the box;
heater;
construction of a Scottish eye for the treatment of joints;
membrane film for waterproofing;
foil adhesive composition, moisture resistant;
self-tapping screws;
facing materials.

As for the tool, it is not possible to install insulation on a wooden base:

The heating technology is not difficult as you can see yourself as you study the information below.

The scheme of fastening the material on wooden walls

At the initial stage of work, it must be installed wooden box from metal profiles or well-dried wooden blocks.

They will act as a guide and a layer of insulation should be placed between them.

The pitch of the lamella must correspond to the dimensions of the insulating boards.

because of high rate elasticity of mineral wool, the laying of the layer can be carried out "on the stand" so that they remain in balance with each other.

This type of device eliminates the formation of "cold bridges".

For safety, you can additionally insulate the insulation around the rim with masking tape.

We have described the simplest technology for installing mineral wool on wooden walls.

In fact, in some areas of the country where particularly harsh climates are used, up to 100 mm thick, they are installed in several layers for each preparation of an individual container.

Naturally, mineral wool materials should not be used to insulate wooden houses.

How to properly insulate a wooden house from the inside: the choice of material and technology, the stage of work

Rules for preparing material and facade for installation

Regardless of how the material was chosen for heating wooden facade walls, it is important to pack it the day before work to take it to its original shape.

The implementation of thermal insulation is better in the warm season without precipitation per day.

Before proceeding with the installation of the heater, it is important to check the structure of the house due to defects that require removal.

If the old finish does not meet the strength requirements, then the correct solution will be eliminated by subsequent cleaning of the facade walls of the house with compounds that protect them from fungi, bacteria and mold.

Given that most wood heaters in the home are based on wool, it is important to protect the material from exposure to atmospheric moisture.

As an option, tiles can be made from roofing iron using sealant to lubricate the joints.

Sheets on the base are better fastened with screws.

facade insulation

As a rule, a two-layer container is usually used to insulate a ventilated facade, with the first layer horizontal bar same width with heater.

This is a rail design that allows the plates to be installed in the spacer without additional installation.

A prerequisite for heaters is the installation of a windproof membrane, on which the second layer of the container with vertical rods is laid.

At this stage, the disc pitch will depend on the selected end material.

It should be noted that the insulating panels on wooden houses can be fixed with clinical umbrellas to the bottom of the wall.

Finally, a few words about the need to insulate wooden houses from the outside.

The fact is that the use of high-quality insulation and proper installation will allow you to correctly distribute the temperature load so that the walls can be stored in operation longer, but not ahead of time.

In addition, the use of insulation for external walls improves the permeability of facade steam, and the outer side of the material is porous, preventing premature wear of the walls.

As for the choice of insulation for the external insulation of wooden walls, her own preferences should be taken into account both in terms of production and aesthetic components.

What heater to choose?

When choosing a heater for the walls of the house, first of all should be paid attention to the ability of the material to pass steam and air while keeping warm.

The severity of the climate of the region of residence should also be taken into account.

Of the materials for insulation can be distinguished:

interventional heaters used at the construction stage;
and heaters used for insulation from the outside or inside.

The interventional insulation is used in the laying of the interventional joints. Such heaters are synthetic and natural (from jute, moss, flax, hemp). The main property of these materials is low thermal conductivity and the ability to accumulate and release the resulting moisture. The most common today are linen and jute fiber insulation.

Basalt (mineral) wool is widely used to insulate walls from the outside or from the inside., or fiberglass wool in the form of rolls or mats, with a density of 80 -120 kg / m3. In addition, it is an environmentally friendly material.

It is not recommended to use polystyrene or polystyrene foam as an element of the pie, since these materials are vapor and moisture resistant and prevent air exchange between the house and the external environment.

Sealing seams and joints of forming elements

This method is an internal wall insulation, aimed at sealing joints and cracks in logs. In this case, various sealants are used (silicone, latex, acrylic, linen rope, tow). This method is convenient in that it is easy to do with your own hands and does not require special skills, it does not prevent steam from escaping and is the most cost-effective.

Technically carried out as follows:

the edges of joints and cracks are cleaned,
cavities are filled with rope, foam rubber;
a layer of sealant is applied on top;
the sealant is smoothed with a brush until a smooth surface is formed;
sealant residues are removed with a rag.

Sheathing preparation and installation

When installing the crate, it should be repelled from the thickness of the insulation. The thickness of the bars will be the same. The most commonly chosen beam 10-50 mm thick and 100 mm wide.

The crate is mounted transversely to the laying of logs with a step between the bars equal to the width of the heat-insulating mats with minus 3 centimeters for tight entry. The height of the crate is individual for individual rooms.

In parallel with the laying of logs, a crate is also similarly mounted (the so-called "counter-lattice"). For the installation of the crate, you should choose high-quality material without traces of decay. Before installation, all wooden parts and surfaces should be treated with an antiseptic.

NOTE!

Do not use thin boards for lathing, as it simultaneously serves as a place for attaching finishing coatings.

Do-it-yourself wall insulation from the inside of a wooden house

Insulation of walls inside a wooden house with mineral wool. When using this method, glass wool, slag fiber, or mineral fiber mats are used.

Such material is the most effective in terms of thermal insulation and sound insulation, environmentally friendly. However, due to its structure, mineral wool allows steam to pass through and is able to accumulate water.

For this reason, when using it in insulation, layers of hydro- and vapor barriers are required.

Mineral wool is available to customers in the form of rolls and mats. When insulating, it is most convenient to use mats by simply inserting them between the profiles of the crate made. In this case, the gaps between the mats should be no more than 2 mm.. Such gaps are subsequently sealed with adhesive tape - best of all foil, or plumbing tape.

Step by step installation:

the required number of mineral wool mats is prepared, based on the calculations of the quadrature of the walls of the premises;
mineral wool is tightly inserted between the battens of the crate;
top mats are cut to height;
gaps and seams between mats are glued with mounting tape.

Some builders use polystyrene foam when insulating walls indoors. However, the main selection criterion in its favor is its low cost. From the point of view of efficiency, the foam plastic does not have the property of passing steam, and the result of its use in the absence proper organization steam and hydro- insulation, will become the so-called " Greenhouse effect» and the inevitable development of mold in rooms with similar walls.

Vapor barrier and waterproofing of walls

Warming of wooden houses begins with waterproofing. This is the closest to bearing walls layer of a special film, the main task of which is to ensure air circulation and protection of the insulation layer from wetting and freezing, preventing its destruction and preserving the tree from the development of mold bacteria.

Waterproofing is one of highlights in wall insulation.

waterproofing membrane

In the process of work, anti-condensate membranes, diffuse breathable films, polymeric multilayer films, and vapor barrier membranes are used. When waterproofing, it is important to maintain complete tightness. To do this, the film is overlapped, and nailed with a stapler and staples, and the seams are glued with mounting tape.

Vapor barrier is top coat, which is laid on top of mineral wool and serves to protect against the penetration of water vapor into the structure of the insulation.

Fastening is similar to the installation of waterproofing.

Conclusion

Thus, responsibly organized wall insulation of a log house can play a big role in the long and reliable operation of a wooden house. It will help reduce heat loss, as well as protect the load-bearing elements of the structure from all kinds of weather conditions.

However, the preparation of such an event should be approached responsibly. How well it will be carried out depends on the life of your home.
