Insulation of log walls from the inside. How to properly insulate an old house? Personal experience of our readers

Despite the favorable climate, wooden structures require additional insulation, since in the most severe frosts you can spend a lot on electricity. Among modern residents, a country house made of solid wood is a luxury. Since ancient times, our ancestors were engaged in the construction of such structures. In order for such a house to be cozy and comfortable to live in, it, of course, needs to be competently. To do this, you need to carry out external insulation of wooden walls. As a rule, structures made of such material have many disadvantages. One of them is the increased heat loss in the cold season.

This problem does not bypass any tenant, so here we will talk about how to carry out high-quality insulation of the old wooden house.

Choosing a heater

The main place of heat loss is the roof. More than 40% of all heat from a wooden house leaves this place. In second place are window openings, from where up to 30% of heat escapes, so you also need to insulate windows in wooden house. Next come the walls and doors wooden structure. The main task of the inhabitants is to patch up all the cracks and holes in the walls. As you know, you need to think about the insulation of a wooden house even in the process of its construction. Otherwise, it will be difficult to make high-quality insulation country house. Here are the materials that are best suited for insulating the seams of a wooden house:

Jute is an excellent material. It is a versatile insulating material. This name comes from the name of the popular plant "jute". It is made from this plant, having previously processed it. This the best insulation for wooden exterior walls. The components include lignin, since it does not rot;
tape tow is an improved flax fiber, in which the developers completely excluded the presence of flax, sawdust and plant particles. This material is useful for sealing large cracks that form in the walls. Insulation of an old wooden house from the outside is best done using this material;
linen felt, which consists of non-woven fiber, is also very popular. It can be obtained after the process of needle stitching using threads of linen material, or other technologies are also used.

The thickness directly depends on the design of the walls of the housing.

If the owners plan to use glued or cylinder beams, then the thickness of the beam with an insulated layer will be approximately 5-10 millimeters.

Everything depends on the climate. The walls made of chopped logs will have a thickness of 15 millimeters.

How to properly insulate the walls of a wooden house

To get the most efficiency, you need to repair work for the insulation of a wooden house. This may be necessary if the home is located in a cold climate where low temperature negatively affects the walls of the house. The insulation of an old wooden house from the outside is a layer of heat-insulating material, which is installed on a special structure made of rails. Insulation work should be carried out after the walls of the housing have shrunk and warm time of the year. Otherwise, the insulation material may be poorly installed. It is also possible to peel it off from the base of the walls, due to excessive temperature differences. Therefore, it is necessary to carry out the insulation of a wooden house from the inside.

But this method of insulation is not ideal, therefore, it has several disadvantages:

the walls of the house, which are located in front of the insulation material, are constantly in the area of the negative impact of sub-zero temperatures, as a result of which the wood begins to crack, which will negatively affect the integrity of the entire structure, so it would be nice to insulate the corners of a wooden house;
between log wall condensation will form, which will lead to the appearance of mold;
the area that is suitable for use is significantly reduced, so you need to purchase insulation for wooden walls outside;
the interior of the house is modified, which by its nature is a unique creation.

The quality of the insulation of a wooden structure is lost due to the lack of an appropriate one. This can happen due to excess moisture in the air, therefore, the insulation of an old wooden house from the outside should be carried out in accordance with all the rules, choosing the best insulation for wooden walls. As a result of this, drops of moisture will form on the walls inside the housing, which will also negatively affect the integrity of the walls.

Due to improper insulation of the outer surfaces of the walls, moisture will get inside insulation material, which will cause increased moisture in the room.

The material for warming a wooden floor must also comply with all standards.

In such a tedious process as insulating an old wooden house from the outside, it is best to use a system with a high-quality air gap, which is designed for additional ventilation.

Insulation for wooden walls outside will be the key to comfort in the house. Thanks to this, moisture will linger and not spoil the insulation material.

This design will keep the walls of a wooden house dry, so they will not crack. Also, thermal protection will be maintained at high level if the owners choose high-quality insulation for wooden walls outside. In the absence of such air gap, the walls will pick up moisture, which will cause mold to appear in the house. At the end, you should also carry out the insulation of windows in a wooden house.

Today, many of us dream of living in our own beautiful house. That's just to pastime in it was as comfortable as possible, it needs to be well equipped. The comfort of living in any house depends on the quality of thermal insulation. This is especially true for buildings made of wooden beams. However, in order for the insulation from the outside, made with your own hands, to turn out to be of high quality, it is necessary to take into account the features of the tree. If this is not done, then the thermal insulation and walls will not last long. In addition, in the process of work, it is necessary to adhere to certain instructions and observe safety precautions.

General information about insulation

To achieve good thermal insulation of a wooden house, it is necessary to take into account two features of wood as building material. Firstly, the tree has a high vapor permeability, and secondly, it is prone to the development of fungi and mold. talking plain language, the tree absorbs moisture very well, which enhances heat loss. Thus, equipping the insulation log house outside with your own hands, you should choose materials that will protect the wood well from moisture so that it does not rot. Another important nuance is ventilation gap, which should be between the insulation layer and the wall. And to prevent the development of fungus and mold, the tree is impregnated with special antiseptics.

Types of insulation

Insulation of a log house from the outside, the technology of which requires compliance with certain instructions, is a rather laborious process. When insulating inside, the insulation material is laid in the room, after which it is sheathed with any finishing material. With external insulation, everything happens the other way around.

Insulation inside the house is used in cases where it is necessary to preserve the natural appearance buildings, for example, if the house was built from a log house.

However, this technology has several disadvantages:

reduction of free space inside the rooms;
constant dampness in the room;
a strong temperature difference inside the house and outside leads to the fact that the tree deteriorates very quickly.

Therefore, in most cases, the insulation of a log house is used from the outside under the siding.

External insulation device

To minimize heat loss through the walls and eliminate the possibility of fungus, when insulating the facade of the house, it is very important that the wall not only prevents heat from escaping, but also breathes.

For this, insulation is carried out according to the principle of "layer cake", which consists of the following components:

bearing wall;
frame;
insulation layer;
membrane film that protects the wall from the wind;
crate for finishing materials;
siding.

With such insulation of the house, the walls breathe, condensate is removed from them thanks to the wooden frame, which is not only responsible for fastening finishing materials, but also creates an air cushion. In addition, condensate cannot disappear on its own, so a vapor barrier layer must be provided between the insulation and the wall, which will protect the insulation from moisture and prevent its damage.

Varieties of insulation materials

To date, the insulation of a log house from the outside, from the inside is carried out according to a similar principle, it can be done using the following materials:

mineral wool;
polystyrene;
extruded polystyrene foam;
ecowool.

Each of the materials has certain advantages and disadvantages, so when buying it, you should take into account all the features of each type of insulation. You can buy everything you need to warm your home in specialized stores.

External insulation of a wooden house: what material is better to choose?

Before you start arranging thermal insulation at home, you need to purchase suitable material. It is very common to insulate a log house from the outside with ecowool. It consists of a collection of fibers that are produced as a result of the melting of rocks. The excellent thermal insulation qualities of ecowool are due to the fact that there is air between the fibers, which contributes to better heat retention.

In addition, the heater also has the following advantages:

ease of installation;
low cost;
high resistance to ignition;
good vapor permeability;
excellent sound and heat insulation characteristics.

If you decide to do external thermal insulation using this material, one should take into account the fact that the insulation of a log house from the outside with mineral wool for siding should provide for the arrangement of wind protection, since this insulation absorbs moisture very well, which significantly reduces the performance of ecowool.

Other types of insulation that can be used to create thermal insulation for a house from a wooden beam are polystyrene foam and extruded polystyrene foam. Both materials belong to the category of polymers, consisting of numerous cells glued together, between which there are pores. It is thanks to the voids that excellent thermal insulation is achieved. It is worth noting that both materials are very similar and are made using reliable technology, however, expanded polystyrene has a higher strength.

Nevertheless, most professionals recommend using mineral wool outside insulation of a log house, since polystyrene foam and its analogues have very poor vapor permeability. Consequently, condensate accumulates between the insulation and the wall, which creates ideal conditions for the development of fungus, mold and harmful microorganisms.

External thermal insulation with mineral wool

Mineral wool, due to its availability and fairly good characteristics, is most often used for external insulation of houses made of wooden beams or log cabins. However, it is very important to understand how much material is required for this. To do this, calculate the total area that needs to be insulated.

In order not to make mistakes in the calculations, you can adhere to the following algorithm:

The ceiling height is measured in each of the rooms.
The total perimeter of all rooms is measured.
The resulting measurements are multiplied for each private room, after which the area of \u200b\u200bthe openings is subtracted from the resulting figure, and then the area of \u200b\u200bgables is added, which can be calculated using the mathematical formula for determining the area of \u200b\u200ba triangle.
Decide which manufacturer's material you will be using. Divide the total area of the mineral wool by the area of each slab. In this case, it is very important to provide for a small margin, which will be necessary to eliminate the error when cutting the mineral. The resulting figure will indicate the amount of mineral wool that each slab consists of for insulating a log house from the outside.

In this case, the amount of material depends on how thick it will be. insulation layer. For regions with a warm climate, insulation can be laid with a layer thickness of 50 millimeters, and for areas with very cold winters - 150 mm. If, for some reason, mineral wool cannot be laid in one layer, then two layers can be made in this case.

What tools will be required?

To make the thermal insulation of a wooden house, in addition to the insulation material itself, you will need a certain set of tools. For the construction of the frame you need electric jigsaw or grinder to cut wooden beam. At the same time, it is important to understand that work will go much faster with a grinder, however, this tool will damage the anti-corrosion coating, which will negatively affect the durability of the material, and the insulation of the walls of a log house from the outside will not last so long. If the frame is made of a metal profile, then in this case you will need metal scissors.

In addition, it is necessary to tighten the screws with something. A screwdriver with a set of nozzles will perfectly cope with this task. It is best to choose a tool with a self-powered power source, because this way you will not be tied to an outlet and will be able to work in any part of the house. Since the insulation of a log house from the outside is a very laborious and long process, it will be useful to get an additional battery. This way you can operate the tool and charge the battery at the same time.

When creating a wooden frame, it is necessary to customize its individual elements. This is done with a rubber wooden hammer. You will also need a sharp knife for cutting mineral wool.

As mentioned earlier, the insulation of a log house from the outside should include a windproof layer. It is created using special film, which is attached to the wooden frame with metal brackets. This will require a construction stapler.

In order for the wall to be perfectly flat after completion of all work, the arrangement of thermal insulation must be carried out using a level, tape measure and plumb line. Without these tools it is simply impossible to do everything qualitatively.

Laying insulation on a wooden frame

Most often, when equipping the thermal insulation of a house, the insulation is laid on wooden frame. In this case, the insulation of a log house from the outside is performed in a certain sequence.

The wall is being prepared. All protruding elements are removed from it, after which the tree is treated with special antiseptic agents. Special attention at the same time it is necessary to pay hard-to-reach places, since it is in them that the fungus and microorganisms most often develop.
A wooden frame is created. For him, it is better to use bars measuring 30x30 millimeters. Horizontal and vertical elements are fastened together with galvanized self-tapping screws, which are highly resistant to corrosion. It is worth noting that the distance between the bars should be 5 mm less than the size of each plate of insulation material. This is very important, because after laying the mineral wool there should be no cracks or gaps. Otherwise, the thermal insulation will be of poor quality, heat loss will occur. Plate-shaped dowels are used to fix the material.
The second layer of insulation is being laid. All work is carried out in the same way as described earlier.
When thermal insulation layer will be completely completed, you can start laying Each subsequent strip of film should be laid with an overlap of 10 centimeters on the previous strip. The membrane is attached to the frame with construction stapler and metal staples. In order for the protection to be of high quality and reliable, the joints of the membrane must be glued with special construction tape.
On top of the windscreen, slats are attached to the wooden frame, on which the siding elements will be attached.
At the final stage, facing works are carried out.

On this, the insulation of a log house from the outside can be considered fully completed.

Installing insulation on brackets

Insulation can be laid not only on a wooden frame, but also on brackets. The process of performing work in this case must take place in a certain sequence.

The outer side of the walls is treated with an antiseptic.
Metal brackets are attached to the facade of the building, at a distance that will be between separate elements crates.
Mineral wool is being laid. To do this, the insulation is simply placed on the brackets and secured with dish-shaped dowels.
A windproof film is laid and fixed on top of the mineral wool.
A metal crate is created on which vinyl panels are installed.

If you strictly adhere to the instructions described above, you will get high-quality and durable thermal insulation.

Conclusion

Regardless of how the log house was insulated from the outside - with clay, sawdust, shavings or mineral wool, when working with any material it is very important to follow the rules for working with it, as well as follow the installation technology. However the best option mineral wool is used as a heater, since it has excellent operational characteristics and low price.

Regardless of the chosen insulation, the arrangement of thermal insulation is recommended to be carried out in the warm season, so that the tree dries out properly. In addition, before laying the insulation material, the walls should be treated with an antiseptic, which will protect them from damage and prevent the formation of fungus, mold, rot and the appearance of various microorganisms and rodents. Only in this way you can create thermal insulation for centuries, which will not have to be changed after just a few years.

Foreword. Log houses perfectly retain heat and regulate humidity, they are the warmest and most environmentally friendly. But there are times when you built log house, and with the onset of cold weather, they realized that the house was quite cool. There are also serious situations when you bought old house from a log, which already requires serious measures for warming. So the question arises for the owners of the house, how to do the insulation of a log house with their own hands, what materials are better to use in their work.

Do I need to insulate a log house?

Owners of log houses are most often faced with drafts in the premises, often blowing on their legs from the floor, the house cools down quickly if the heating is turned off. From all this, it is concluded that a log house should be insulated with high quality, and start from the floor, as it blows strongly and gives off a lot of heat. The ceiling should also be checked, as up to 70% of the heat can escape through the attic.

To retain heat, it is necessary to insulate the attic or attic floor, process the outer walls and all structures - windows, slopes and window sills, entrance doors etc. Do not forget to check whether the walls are carefully caulked, maybe cracks have already formed over time. We also note that it is necessary to make heating more efficient, it is possible to equip "warm floors" in addition to the existing system.

Too thin walls of the house are also the cause of the cold in the room. For example, for a climate with low humidity, logs with a thickness of 200 - 240 mm are sufficient; for regions of Russia with wet winters, it is advisable to use logs for walls with a diameter of more than 400 mm. Next, we will consider what materials are best used to insulate a log house, if the house has already been built, but there is no comfort in it.

Materials for warming a log house

The standard work procedure includes caulking the walls, insulating the attic, insulating window and door slopes, as well as floor insulation in the house. If you do the job right, then additional measures no longer needed. For warming wooden houses it is best to use natural and natural materials, in addition, it is cheaper to insulate a log house in “old-fashioned” ways.

To insulate the attic, you can use sawdust mixed with clay or earth, expanded clay or ecowool. The walls of the house are caulked with moss, hemp, tow or jute - a flax-based tape insulation. To insulate a wooden floor, you can use bulk materials(expanded clay), or you can use mineral wool in rolls or make a Knauf underfloor heating device from environmental materials.

If after all these standard procedures it is also cold in the house, then one cannot do without additional work on warming the walls of a log house. material to be insulated wooden walls, must be vapor-permeable if it is laid outside the building; moisture resistant so as not to accumulate moisture; environmentally friendly, fireproof and sustainable insects and small rodents.

Given the above characteristics, for wall insulation, you can use ecowool or mineral wool, for insulation of the attic and floor, bulk materials - expanded clay or sawdust. It is not advisable to use materials such as polystyrene foam, polyurethane foam, extruded polystyrene foam - the use of vapor-tight materials will lead to decay of the wood.

Stages of warming a log house from the outside

Walls should be insulated when insulation measures have not brought results. At the same time, it will be right to insulate the house from the outside - this is due to the properties of the tree to breathe. In the case of external insulation using the ventilated facade method, air and moisture will come out of the wood and ventilate freely. If the house is new, then you can start warming after a year, when the log house sits down.

Log house caulk

Even if you decide to insulate the house, the first step is to carefully caulk the walls. We examine the walls for cracks. Caulking should be done in dry, warm weather, using tow or hemp. As well as in the case of warming a house from a bar, we put the material into the slots and push it with a special spatula until the material enters.

Ventilated facade device

Insulation of a house from a log house from the outside

Insulation of the log house from the outside is carried out by installing a ventilated facade. The design allows the tree to "breathe" and give off excess moisture. In order to visually demonstrate the process, we have added a video - video instruction from the manufacturer of modern effective heaters. Stages of installing a ventilated facade on a wooden house:

1 . we treat the walls with an antiseptic;
2 . on top we fill the crate with a step equal to the width of the insulation boards;
3 . we insert the insulation plates, tightly installing them between the guides;
4 . on top of the insulation we mount a wind protection from a waterproofing membrane.
5 . on top of the windshield we fill the crate and mount the siding.

The superdiffusion membrane will not allow moisture to pass into the insulation, but will release moisture from the material to the outside, giving the walls the opportunity to "breathe". To do this, a ventilation gap is formed over the entire thickness of the crate (the distance between the superdiffusion membrane and the siding). Air vents must be provided at the top and bottom so that air can circulate from bottom to top.

Attic insulation in a log house

This insulation option should be used in extreme cases. Specialists are against installing insulation inside the room, as the tree stops breathing and will become damp. It is possible that standard insulation measures will be enough inside: floor insulation, slopes of windows and doors, ceiling, while you already know how to insulate the attic of a private house with sawdust or expanded clay chips.

If the house is one-story, then we lay it on attic floor waterproofing film, and on top we lay a heater with a layer of up to 250 mm. If the house has an attic floor, then it is necessary to insulate the roof from the inside and the ceiling between the floors. 50 - 100 mm of insulation should be laid in the ceiling. To insulate the roof, we lay waterproofing, lay mineral wool with a layer of 150 - 200 mm and close the insulation with a membrane.

Insulation of walls inside the house from a log house

Mounting insulation inside log walls is not worth it, it is better to properly caulk the cracks, insulate window and door openings. For this we use jute, roll interventional insulation, tow or moss. Can be used for wall decoration wooden lining- the room will immediately become warmer due to an increase in the thickness of the wall, as well as the appearance air gap from the warm room.

Floor insulation in a log house

In order for the floor to be warm, it is necessary to lay a heater between the lags, and lay a rough and finishing floor on top. As you can see self-insulation log house is a set of measures. If you do the work carefully, start from the ceiling and floor, caulk the walls, insulate windows and doors, then the need for wall cladding may disappear. If all else fails, then you can build and insulate a wooden veranda on the north side of the house, expanding the area of \u200b\u200bthe house and forming an air barrier to the cold.

The tree has a low thermal conductivity, so it is believed that houses made of such building materials do not require additional insulation. However, in reality this is not entirely true, because when laying a beam or log, in any case, gaps remain, from where it penetrates cold air. They can be located in the walls, in the floor and ceiling, making the internal temperature in the room uncomfortable, giving reason to think about warming it.

In this article, we will look at:

reasons that affect the preservation of heat in;
how to properly insulate a log house from the outside and organize a ventilated facade;
what kind thermal insulation materials will be required.

Why is it cold in a wooden house

Insulation of log buildings does not require the invention of the bicycle. This technology is very simple and accessible to most citizens.

Therefore, for starters, you should try out standard methods that will allow you to close the access of cold air to the inside of the premises:

First of all, it is worth doing the floor and ceiling, from where it most often comes from.
If this method will not bring desired results, drastic measures should be taken - to use outer skin structures. Though this method not only simple, but also very effective.

Tip: before complaining about the cold in the house and starting to insulate it, you should wait until it goes through the entire drying process. As a rule, it is necessary to enter a log house and carry out any work not earlier than one year after construction.

Caulker

Start the process of warming the house with his own caulking. Everything should be closed large cracks, carefully filling all the free space between the crowns. In most cases, this is sufficient.

It remains only to find all the large cracks. As a rule, having looked around the house with just one look, it is unlikely that you will be able to find them.

Now that the scope of work has been determined, you can begin to caulk it.

Why should you prepare the following tool:

caulk or spatula;
roll insulation, tow or jute.

The process of warming itself is extremely simple and lies in the fact that with the help of special tool(caulks) and insulation gaps are plugged with outer side at home.

The facade must be ventilated

The outer wall of a wooden house must be ventilated, otherwise the material will begin to break down under the influence of various microorganisms, including rot and mold. Only a ventilated facade can provide unhindered air circulation. Thanks to him, the house can continue to release water vapor through the walls and "breathe" without turning into a clogged vessel.

The instruction for its manufacture is as follows:

Treat the walls with an antiseptic- a special solution that protects the building material from the negative effects of microorganisms and environment. The building must be processed around the entire perimeter, excluding possible gaps. Antiseptics can be completely transparent, but some of them have color pigments added, which allows not only to protect wooden structure, but also to give its walls the desired shade.
Attach the waterproofing layer to the wall of the house. In this case, the membrane has proven itself best. Its price is small and you can buy it in almost any hardware store.
Attach to walls. At the same time, they should also be treated with an antiseptic, which will make the facade more durable. All bars are nailed vertically with nails. The latter are selected longer than the bars, which will give rigidity to the entire structure.

Place the elements of the crate opposite each other at a distance that is slightly greater than the width of the insulation. At the same time, additional space is needed for attaching heat-insulating mats to it.

Tip: any material that can perform the function assigned to it can act as a heater. But the most effective and safest will be the use stone wool, as this material is fire-resistant and does not pass moisture.

additional information

Lay another layer between the wall of the house and the insulation, as there is a danger of “cold bridges” that will negatively affect the entire insulation process.

Install stone wool slabs under the battens. Again, it is necessary to exclude the occurrence of "cold bridges", so the mats should fit snugly against each other.
Make a starting bar that will help avoid uneven work. Lay the first layers of stone wool on it, ensuring the evenness of further rows.
Start fixing the insulation from the bottom and gradually move up. And in order to avoid possible irregularities, before starting work, you need to mount the starting bar.
Lay a layer of waterproofing over the mats after they are securely fastened.

Tip: the durability of a house depends not only on the right materials for its construction, but also on waterproofing. If it cannot fully perform its functions, its walls will be covered with mold and fungus.

Walls under waterproofing must breathe, and this can only be achieved by using membrane materials that will not let moisture in and will not let it out.

Start installing another layer of crate, which is made from the same bars.
Make wall cladding with pre-prepared material. The most popular and available is vinyl siding, the color of which can be selected depending on personal preferences. To make the house look more natural, you can choose a color that imitates wood or stone.

Main nuances

External insulation of the house is very effective measure, however, its use does not allow you to save the house in its original form. Therefore, it is advisable to use it only in extreme cases, when other methods are ineffective.

To begin with, you should still try to insulate the building with inside, you need to find and caulk all the cracks. After that, you can take drastic measures and insulate the building using the same insulation. At the same time, the technologies for warming a house from the outside and from the inside are almost the same.

Output

Compared to a brick building, where each brick is placed on a mortar that eliminates the occurrence of cracks, a log house does not seem so successful. But everything is not as bad as it seems, since only a healthy atmosphere always reigns here.

It is desirable to find alternative routes way out of the situation and not spoil the appearance of the building. At the same time, the process of warming is not so complicated, so it can be done quickly enough. The video in this article will provide an opportunity to find additional information on the above topic.

How to insulate a room? For example, an old wooden house? In what cases is it required? These questions concern many owners of such structures. Additional insulation is required when the walls of the building are not able to properly retain heat inside.

It is the layer of insulating material that is able to reliably protect the walls, extending their life, from ultraviolet radiation and moisture, and also act as a barrier between warm air inside the house and cold outside.

Surface preparation for insulation

During the preparation, it is often necessary to remove all the plaster or old insulating material to the base, so that in the end a clean and even wall of wood, blocks or bricks remains.

Insulation of a wooden house, when all work is done by hand, implies a high-quality surface primer, for which a deep penetration compound is used. If there are differences in the level (pits or mounds), they need to be combed off or covered with a solution. Before work, dust is removed from the wall surface.

A complex of plumb lines and lighthouses is created in advance, which in the future will make it possible to lay the insulation evenly by determining its outer edge. So the layer of material will not interfere during the complex of finishing and facing works.

This is done by screwing screws on top of the wall. Threads with sinkers are tied to them and lowered. Horizontal lines are made in the same way. They form a control grid for high-quality laying of insulation.
This is followed by a stage, the specifics of which depends on the type of material. For example, consider the option with polystyrene foam.

Works with expanded polystyrene or extruded polystyrene foam

Warming a wooden house with this material implies a certain sequence of work. First, a control corner is mounted along the lower edge, through which the stacked sheets are aligned. Expanded polystyrene is fixed on a special glue by pressing the sheets against the wall. The control grid will not let you make a mistake.

The second layer is fixed in the same way, but offset to the side by half the sheet. Fixation is carried out anchor fastenings, which are clogged in the center of the sheet and at its corners. Concerning window openings and corners of the walls, then at these points a metal corner is used to fasten the plates. A reinforcing tape is used to glue the seams between the sheets.

Further, extruded or ordinary polystyrene foam is covered with a reinforcing mesh, after which it is plastered. This material is optimal for the insulation of concrete or brick walls. The only negative is the low vapor permeability. And this will not allow condensate to be removed from the surface of the walls of the old house. To solve the problem, it is recommended to dry the walls thoroughly before starting work, and upon completion, install a ventilated facade.
Warming procedure different designs of a wooden house requires that at the end of this stage there should be no access to the laid polystyrene and rodents could not spoil it.

Internal work

On this moment exists different ways performance of works that depend on the materials used.

Warm seam

This scheme allows you to significantly reduce the thermal conductivity of the joints of walls and seams. It is used when wall decoration with decorative plasters is not planned.

Laying is carried out directly between the beams of the structure using natural (linen rope, flax or tow) or synthetic (latex, acrylic, bitumen-rubber, silicone) sealants.

Works with mineral wool

For insulation, mats made of glass wool, basalt (mineral) fiber or slag fiber are used. Such a material has excellent indicators of thermal insulation qualities, noise absorption and environmental friendliness. The problem is that it has a fibrous structure, and this contributes to the accumulation of water in it. Bottom line - it is imperative to lay layers of hydro- and vapor barrier on the walls of the old house.

Work progress:

Training. This method initially involves the putty of all defects, cracks and cracks, using a synthetic sealant. Next, the surface is treated with an antiseptic composition.

Crate. This method of insulating structures, in particular, a wooden house, implies the need to install a crate. First, a transverse crate is fixed, which is stuffed from a metal profile across the logs and with a step of 80 cm. The frame of the counter-lattice is created in a similar way with the same step, but already along the logs. The design performs the function of providing ventilation, removing excess steam and preventing condensation.

It is advisable to use mineral wool in mats, because this structure material allows him to save thermal insulation properties even under heavy mechanical loads. The mats are placed at odds between the elements of the crate with a maximum allowable joint width of 2 mm, which are subsequently sealed with a special adhesive tape.

Vapor barrier. To prevent its rupture due to thermal expansion of mineral wool, the vapor barrier is laid with an allowance and overlap - this method is optimal.

Finishing. For this, drywall, chipboard, lining or fiberboard is used. They are fixed directly to the profile or logs, and the thickness of the seams should be minimal.

The sequence of operations must be followed strictly.

For work, a sawdust-cement mixture is used. The required amount of sawdust is calculated based on optimal thickness warm ceiling in a wooden structure - twenty centimeters. To get the total cubature, you need to measure the surface area and divide by five. The ratio of cement and water is 1 to 10, and water and sawdust - 1.5 to 10.
The insulation scheme designed for a wooden house sets certain criteria for chips:

age - from 1 year;
dryness;
size - too small will not work, as more cement will be required, which will worsen the performance of the composition;
sawdust should not emit a moldy smell.

Composition laying technique

Work order:

do-it-yourself processing of all wooden components with an antiseptic;
laying sheet waterproofing on the entire floor between floors;
mixing the mixture in the indicated proportions;
uniform laying of the solution on the floor;
tamping of the heat-insulating layer.

Floor work

Insulation of an old structure, in particular, a wooden house, may require the replacement of the log, as well as the alteration of the draft floorboards, but not always.

Installation lag

In the presence of serious damage to any of the fundamental beams, it must be replaced. It will take a lot of time - at least a day.

As the lags are flooded concrete mortar, the damaged beam will have to be cut out of the thickness of the concrete. Next, you need to expand the mounting hole so that you can install a new log with a cross section similar to that of the rest of the beams.

The seat for the timber is prepared using a roofing wrap or resin, and the log is pre-treated with an antiseptic composition. Upon completion of the replacement, it is required to fix the beam in the mounting nest with gravel, inspect the level and concrete with a solution of cement and gravel. Then it remains only to wait for the mixture to solidify. This method will give the maximum effect.

Subfloor installation

Insulation of a wooden house involves the creation of a subfloor. Initially, a crate is attached to the log screw, which is created from bars with a section of 50x50 mm and stuffed in parallel. This is followed by the filling of subfloor boards with a thickness of at least 20 and a width of 200 mm. Fixation occurs by means of simple nails, but so that they do not "enter" the logs. The boards must be of the same thickness so that there are no distortions in the coating, while the gaps between them are allowed up to 1 cm in size.

The seams of the subfloor of a wooden house are insulated with a heat insulator.
Everybody wooden elements(logs, crate, etc.) are recommended to be treated with special antiseptic compounds, as well as fire retardants. These funds ("Senezh", "Pinotex", "Finesta") are not too expensive, so you should not save on their purchase.

Laying waterproofing

In the process of warming wooden houses, it is necessary to use only a membrane film that does not allow moisture to pass "up". During installation, it is required to leave 10-15 m from each edge for smell, and then glue everything with adhesive tape with moisture-resistant characteristics.

Finishing logs

These beams with a section of 50x150 mm or 75x150 mm (for rooms where heavy furniture will stand) are mounted in 1 meter increments. Naturally, the 150 mm width limits the parameters of the insulation. Therefore, if it is planned to lay a thicker layer of material, the thickness of the lag should be greater.

Before installing new logs, it is required to mark the location of the draft ones by making marks on the floor. Fixing the finishing logs is carried out with long screws and a screwdriver so that the screws go into the lower logs. Between the finishing beams and the wall, it is required to leave a gap of 2-4 cm.

Laying insulation and installation of the finishing floor

Directly on the membrane waterproofing, in the gap between the lags, a heater (mineral wool, foam plastic, foam plastic, etc.) is laid. A combined method is allowed, but the insulation of seams carried out in a wooden house must be implemented without fail. No additional fixation is required, it is only necessary to ensure that the material does not crawl out and completely covers the entire space between the beams.

Both new and old boards are used to stuff the finishing floor, and screws or nails act as fasteners. Various materials are used:

floorboards (studded, milled or tongue-and-groove);
massive board;
laminate;
DVP and others.
