What is a thermal circuit for a house made of glued laminated timber. Close the heat circuit

To begin with, we note: the term "thermal circuit" is not fixed in normative documentation, this concept is from construction practice. But the concept is very capacious, which is why it is used by experienced builders of individual houses.

At the initial stages of construction, the foundation of the building is being built and bearing walls, which form the basis of the so-called thermal circuit, which then needs to be "closed" to save what has already been built. Any unfinished building is vulnerable to external influences: a freshly built wall can begin to rot, crumble, absorb moisture and eventually lose its properties. And the foundation may gradually lose its bearing capacity, and in this case it is unsafe to live in the house.

The biggest threat to an unfinished home is our harsh climate. In the summer (if you're lucky with

weather) the box can still stand without much damage, but in the fall or winter, such an overstay entails a number of negative consequences. And all wall materials behave differently. Woody more than others are afraid of atmospheric moisture, under the influence of which they can rot and lose strength. Brickwork and concrete monolith are more resistant to rain and snow, but aerated concrete also does not like moisture. An unprotected aerated concrete wall absorbs it intensively and partially collapses and loses some mechanical properties when water freezes in the pores.

However, any building should not remain in the autumn winter period open to all weathers. It should be protected - perform a set of works to close the circuit.

Complex of works

A reliable roof is needed to protect against rain and snow. That is why, after erecting the walls, one should, without delay, put the truss system, and lay the selected one on it. roofing material. Moreover, it is necessary not only to lay the roof, but also to close all technological openings in it.

Many engineering systems, without which it is impossible to imagine modern house, require the output of chimneys, ventilation risers, antennas, etc. to the roof. When a riser or chimney is installed, the sealing of the exit to the roof is ensured by the installation technology itself - and if the house is unfinished? In this case, at the stage of closing the circuit, it is necessary to carefully seal the technological openings in the roof, since both moisture and cold wind easily penetrate through them.

Uncontrolled water flows on the roof - also not the best way. And if the roof is already installed, then it is desirable to install a drainage system. In this case, prolonged autumn rains, which are not uncommon for our region, will not harm the building.

Door and window blocks it is also better to install before the onset of slush and cold weather. If double-glazed windows are not inserted, then reliable sealing of openings is necessary. For this, thick plywood is used, OSB boards or other materials. Sometimes protective shutters are also installed, but they are not included in the mandatory list.

Plastering, painting and facing works on the facade require a separate discussion. Here the need for one or another is dictated by the choice of building material. For example, it is desirable to veneer the facade of an aerated concrete box before the building is mothballed. In extreme cases, the surface can be treated with a hydrophobic solution to protect against moisture.

If it is possible to protect brick wall plaster, it is worth doing it before the onset of cold weather. Although the brick, we note, ceases to be cold months without much damage. Not bad tolerate winter and wood wall materials natural humidity. Moreover, log cabins made of such materials even have to stand for several months in order for the shrinkage processes to complete. Wood for this period can be treated with antiseptics and water repellents.

The thermal circuit includes ready-made foundations and walls, installed windows and doors and sealed roofs. Some builders include in it and internal walls and partitions, others believe that the filling of the house is arranged already at the next stage of construction. The same can be said about insulation. Someone believes that closing the thermal circuit involves insulating the outer walls, while someone postpones this operation.

Thermal contours of houses from different materials may differ. For example, in a house made of chopped logs, when closing the thermal circuit, you will have to lay a rough wooden floor. But for a brick or aerated concrete box, this is not necessary. One of the subtleties is that it is not necessary to completely clog the building (oddly enough) for the winter. Ventilation of the internal space must be organized, excluding the accumulation of moisture and the formation of ice with its subsequent melting. Such ventilation should not be spontaneous, so that the winds roam freely inside, but air exchange with environment needs to be fixed.

When the circuit is closed correctly and the interior of the unfinished house is reliably protected from atmospheric influences, the building will stand until the next season with little or no damage. The main goal of these measures is to eliminate or at least minimize damage to the supporting structures of the house.

Separately about communications

At the production stage, the construction works internal communications, as a rule, are not mounted. Only external communications are brought in and in some cases they are brought inside the building. However, take into account the presence engineering networks in the house is necessary, including during the closing of the circuit.

The conclusions of chimneys and ventilation risers on the roof have already been mentioned. However, there is still water supply and sewerage. In an unfinished box, these communications do not function, but the inputs of external pipelines are usually already made. The pipe of the main water supply can be introduced and temporarily muffled, as well as a sewer pipe laid to the septic tank on the site. And all these inputs should be carefully sealed. The septic tank also needs to be protected from external influences. Then in the new season, the installation of water supply and sewerage systems will take place without problems.

Important milestone

Closing the thermal circuit is milestone building a house. We can say that at the same time, enclosing structures are being built, arranged according to energy-saving technology. Some builders upon completion say: if you put a boiler or stove, you can already live in the house. And this is a completely fair statement. After the thermal circuit is closed, we can assume that not even half the work has been done, but more. In such conditions, it is much more convenient to deal with interior decoration and installation of home engineering.

A word to the experts

Dmitry Modestov CEO company "Yamera"

A closed circuit is that stage of home readiness at which the box is protected from atmospheric phenomena (snow, rain, hail, wind). The amount of work required for safe wintering depends on the materials from which the house is built. Applied to the house cellular concrete the cycle of works includes: foundation installation, wall construction, installation and waterproofing of the roof, installation of windows and doors. All horizontal surfaces should be protected from precipitation, while vertical sections aerated concrete walls can remain unfinished. For a safe wintering at home without heating, you need to take care of the foundation. Even at the foundation design stage, it is necessary to determine whether the house will always maintain a positive temperature or whether it can remain without heating for the winter period. If the project provides for a constant positive temperature in the house, then its closed circuit cannot be left for the winter in vivo, since this can lead to freezing of the soil under the foundation from the inside of the house and deformation of the foundation and, as a result, cause deformation and damage to the walls, distortion of door and window blocks, etc.

Sergey Vytnov Construction Director, PSK Rosstroy

Closing the circuit and conserving the house for the winter involves a set of works to protect the house and its elements from the adverse effects of low temperatures, precipitation and periodic freezing and thawing. Before the onset of the winter season, it is necessary to protect window and door openings from precipitation, close the chimney and ventilation pipes and their connections to the roof, insulate the foundation, and it is advisable to arrange water drainage from it.

If in the supply water pipe water remains, it can be easily removed using a hydraulic level. A hydraulic level is lowered inside the pipe, the upper hole is plugged with a finger and the hydraulic level is pulled out with part of the water. This manipulation must be performed several times, until the water level in the pipe drops below the freezing depth. AT sewer pipes there is no water, so no action is required. If plumbing is installed and connected, then antifreeze can be poured into the water seals.

A word to the experts

Denis Nikolaev Construction Director of Finnstyle LLC, official representative of Honkamajat ltd

First of all, closing work warm circuit involve the construction facade walls, complete roof installation with insulation, windproof and hydroprotective layers. The next step is the installation of all translucent structures around the perimeter of the facade, as well as the installation of all street doors(front, back or auxiliary entrance, terrace doors, etc.). Then the technological seams are filled with all necessary materials, after which they close with outer side temporary or permanent platbands, depending on the further finishing of the facade. This is necessary, since, due to climatic influences, materials for filling joints quickly collapse and lose their technological qualities.

All this must be done before the winter season. Then we can assume that the contour of the building is closed, or, as the builders say: the warm contour is closed.

When conserving a house for the winter, care must be taken that moisture does not penetrate into the room, the outlets of the chimney and ventilation pipes should be covered with decorative caps. At the same time, it is not worth plugging them tightly - the house will be ventilated through them, which will help to avoid wet stagnant processes. It is also necessary to ensure ventilation of the underground space. Of course, a gutter system will help the house to overwinter, which will prevent rain and melt water from flooding the facade.

As for the water supply and sewerage, these communications are laid below the freezing depth of the soil, the entrance to the house must also be made taking into account freezing, that is, from under the foundation. If the water supply system to the house and the sewage drain were tested, then the water should be drained as low as possible through the system, and the water meter unit in the house should be insulated thermal insulation materials. All outlets of the sewer system in the house must be caulked with soft insulation - this will help to avoid freezing of the water remaining near the outlet during the tests and prevent the occurrence of odor.

Bridges of cold call the sections of the building envelope through which the largest occur, which leads to a number of negative consequences. Today we will talk about how to prevent the appearance of cold bridges in an insulated (mansard) structure.

Cold bridges in insulated construction pitched roof causes many problems:

1. Firstly, they reduce the effectiveness of the thermal protection of the building, which increases energy consumption by , which, in turn, results in an increase in the cost of operating the house.
2. Secondly, during the cold season, condensate accumulates in the freezing zone, which leads to wetting and gradual damage to the roof used for insulation (which also worsens the thermal protection of the building).
3. Thirdly, due to condensation, they can become moldy, rot and collapse over time. wooden structures roofs. Often, condensation causes deformation of the finish.
4. Finally, fourthly, condensate can freeze in winter and break the cracks and gaps that it filled.

Heating errors

What causes cold bridges? According to experts, in most cases this is due to errors in the construction of the heat-insulating layer of the roofing "pie". Recall that most common building technology mansard roof involves the insulation of slopes (which are at the same time the walls of the attic) with fibrous materials: slabs and - less often - mats based on or.

Another knot dangerous in terms of freezing is the junction of the roof with the gable of the building.

Valery Nesterov, CEO of Dörken:
“At the junction of the roof with the pediment of the building, the probability of freezing is very high. To prevent it in the West, there are special U-shaped elements made of extruded polystyrene foam, which are “put on” on the gable wall. On our market there are special diffusion hydrowindproof membranes with an integrated layer of insulation 30 mm thick made of nonwoven fabric: they can also protect this area from freezing. However, the traditional solution is to fill with mineral thermal insulation the space between the outer rafter and the gable wall (usually about 50 mm), the gap between the upper surface of the wall and the hydro-windproof film, and also lay the insulation along the upper edge of the wall. As a result, a continuous heat-insulating contour is created that closes the pediment and transfers the dew point inside the wall, thereby eliminating the possibility of condensation in the thickness of the roofing insulation.”

1. The first difficulty lies in the fact that often on the entire upper part of the sloping gable wall there are ledges formed due to masonry (made of bricks, blocks). To level the wall, a "cold" cement-sand mortar is often used, which becomes a cold bridge. It is better to use a "warm" solution with the addition of it instead. Or fill the irregularities with thermal insulation.
2. The second difficulty is to insulate this place with high quality. It is necessary to leave a distance of at least 50 mm between the rafter leg closest to the gable and the gable wall, filling this space with thermal insulation. In addition, it is desirable that the upper plane of the wall be 50 mm lower than the upper plane of the rafter legs, and then the insulation is also laid on top of the wall at the height of the leg, ensuring its snug fit to the insulation running along the rafters. If possible, the insulation is also mounted along its edge from the side of the street - with a layer of thickness equal to the thickness of the insulation on the roof slope.

Here you can use both fibrous thermal insulation and materials from. It is preferable to put insulation on top of the pediment even before laying the hydro-windproof membrane - for the same reasons that we talked about a little higher.

Freezing through the rafters

Joints are also problematic. wooden elements roofs (located between its warm and cold zones), as well as composite rafter legs made by combining two beams into one. Cold bridges can appear here for several reasons: due to the loose fit of the elements to each other (caused, among other things, by their curvature), due to settlement truss system etc. To avoid this, joints should be laid with sealing materials, for example, synthetic winterizer or foamed polyethylene. However, a number of roofers believe that the latter reduces the reliability of the connection of wooden elements. If you have to seal the joints after the installation of the rafters, then you can use specialized sealants, PSUL (pre-compressed self-expanding sealing tapes) or mounting foam However, this is not cheap and rather laborious. Have this decision another significant disadvantage: the foam, being inelastic, can collapse when a wooden structure settles.

An effective way to prevent heat loss- create an additional layer of roof insulation, blocking possible cold bridges.

On the picture:
1. On roofs of complex configuration, it is inevitable to cut the insulation boards in order to fit them into the space between the rafters.
2. Fastening the vapor barrier film to the rafter leg.
3. Installing the undercut slab in the ridge area.
4. Slots in the insulation layer are caulked with fragments of the same heat-insulating material.

Freezing is also possible in places where the Mauerlat, ridge or intermediate runs through the wall go out onto the street, on which the extended rafters rely. To prevent the movement of cold air here, you must first seal the gaps between the beam and the wall, and also do not forget to seal (glue with glue or special tape) the places where the vapor barrier and hydro-windproof films bypass the beam.

The roof window area is another section of the roof where cold bridges can occur.

Often this happens due to the absence or insufficient thickness of the insulation layer around the perimeter. window frame and along slopes. In order to prevent freezing, it is necessary to leave a gap of 20-30 mm around the frame, filling it with thermal insulation, which should be brought to the roof insulation contour.

To simplify installation, window manufacturers offer ready-made kits for thermal insulation around the perimeter of the frame(e.g. polyethylene foam). Some companies produce windows with heat-insulating ones already provided on the frame. Note that window manufacturers categorically prohibit insulating the frame with mounting foam.

Marina Prozarovskaya, Chief Engineer Velux company:
“Among the reasons for freezing in the area of ​​the roof window is the lack of thermal insulation around the perimeter of the window frame. Often this is caused by too small mounting gaps between the box and the rafters. It is necessary to leave a gap of at least 30 mm around the perimeter of the frame, installing either a ready-made heat-insulating contour made of polyethylene foam or a fibrous insulation around it. Mounting foam cannot be used for these purposes: it is inelastic and under the influence of periodic loads (roof settlement, snow, wind load) crumbles, resulting in cracks in the thermal insulation. If the width of the window is equal to the width of the inter-rafter opening or exceeds it, then in order to provide the necessary mounting gaps around the frame, it will be necessary to adjust the rafters, while maintaining their bearing capacity. Sometimes this can be done without special calculation according to the schemes indicated in the window installation instructions. Usually this involves the installation of an additional beam, the section of which coincides with the section of the rafter leg.

In most cases, cold bridges are the result of condensation leading to wetting of the insulation in the window area. There can be many reasons for its formation. In particular, non-glued joints of the vapor barrier film with window frame: water vapor has a high penetrating power, and when it enters the cold zone, it condenses. Often, condensation is a consequence of certain errors in the installation of the ventilation system of the roof structure.

For example, there are no conditions for air inflow or its exhaust, a counter-lattice that forms a ventilation gap is not provided, or its height is insufficient to provide the necessary air movement under. However, non-sealed joints and junctions of both roofing films, as well as insufficient ventilation of the roofing space are errors that lead to condensation and freezing. not only in the window area, but throughout the roof. It's just in the window area that it becomes noticeable in the first place. Moreover, many errors cannot be corrected during the operation of the building without the complete dismantling of the roof.

According to experts, in the conditions of the Moscow region every 5 cm of thermal insulation saves on heating an average of 18 rubles. per 1 sq. m of roof area per year.

A few more words about roof window. Problems arise and in case of improper installation of the drainage gutter above window opening. This gutter removes water (leaks, condensate) from the window, which flows down the hydro-windproof membrane to the window. Before laying it, the membrane is cut, and then its edge is inserted into it, securing it with a special clamp, after which the upper edge of the window waterproofing apron is already inserted under the gutter. If the gutter installation technology is not followed, leakage into the insulation is possible with all the ensuing consequences.

Heat-conducting inclusions in the roof structure become certain passage elements - pipes, antennas, flagpoles, etc. Therefore, they must be insulated with high quality and vapor barrier and hydro-windproof films should be hermetically joined to them.

To minimize freezing through the walls, experts advise creating an additional heat-insulating belt about 250 mm high on top of the standard insulation contour (that is, above the roof). To protect against precipitation, the belt must be closed with one or another apron.

Ekaterina Kolotushkina, Product Manager, Saint-Gobain CIS:
“To make the attic as comfortable as possible for living and to ensure the durability of the roof structure allows the creation of an additional insulation circuit. The fact is that the wooden load-bearing elements of the roof are, to some extent, cold bridges. In addition, according to calculations, the thermal insulation layer in the central part of Russia should be 200 mm, however, the thickness of the most popular beams on the market used for rafters is 150 mm (and the insulation is placed in the space between the rafters). Thus, it makes sense to create an additional thermal insulation layer, which will provide the required thickness of insulation and block the cold bridges going through the rafters. This layer can be placed above and below the rafters, laying the insulation between the bars nailed across the rafters. Thermal insulation above the rafters is preferable, because in this case they do not freeze through.

Additional layer of insulation

Despite all the efforts of roofers, heat losses are inevitable in those places on the roof where the area of ​​​​the inner “warm” surface is less than the area of ​​\u200b\u200bthe outer “cold” one. These are mainly the corners of hip or hip roofs (in the zone of convergence of the ridge and the cornice overhang), the places where the slope adjoins the gable, etc. In addition, wooden rafter legs are also, to a certain extent, cold bridges. Yes, and it is difficult to insulate complex sections of the roof where filigree pruning is required (valleys, ridges, junctions). Finally, the thickness of the thermal insulation layer in middle lane Russia should be, according to SNiP 23-02-2003 " Thermal protection buildings", not less than 200 mm. While the most popular material for the construction of rafters is still a section of 150 × 50 mm, which implies a thickness of the inter-rafter insulation layer of 150 mm. All these factors justify the need for additional contour of the thermal insulation of the roof.

It can be mounted over the rafters and under them. In the first case:

1. Stuffed across the rafters wooden bars of the required section, between which the insulation plates are installed.
2. A hydro-windproof membrane is laid over the bars.
3. A counter-lattice, crate or solid flooring is fixed on it, and roofing material is placed on them.

This option is effective in terms of thermal protection, because roof structure will be entirely in the "warm" zone. However, it is not without drawbacks:

• Fixing the roof to the base is less reliable due to the additional wooden substructure.
• In addition, when installing hydro-wind protection, the joints of the sheets may be on a heater (and not on a wooden base), and the installers will push through the film, moving along the roof.

Therefore, the optimal technology is additional insulation under the rafters. In this case, from the side of the room, transverse bars are attached to the rafters, thermal insulation is laid between them, and then it is covered with the attic finishing material.

There is another effective, but so far almost unused method of insulation - installation over rafters continuous flooring, on which slabs of high density stone fiber, wood fiber, polyurethane foam are laid. The roof is mounted directly on the slabs.



1. Rafter leg.
2. Additional contour of warming.
3. Cross bar.
4. Finishing the attic.

Let's note one more point. In the fight against freezing of the roof will help modern methods detection of cold bridges- examination with a thermal imager or hot-wire anemometer. The cost of purchasing or renting these devices is less than the cost of repairing a freezing roof.

In most cases, it is more profitable for a private developer not to buy a thermal imaging camera, but to contact specialized company, which is engaged in thermographic expertise of buildings.

Types of insulation for pitched roofs

To insulate a pitched roof, slabs (or mats) made of stone or glass fiber are most often used.

• In our market, stone fiber materials are represented by Rockwool (Denmark), Paroc (Finland), Nobasil (Slovakia), TechnoNikol, Isoroc, Knauf (all Russia) and others.
• Glass fiber insulation is offered by Isover (France), Ursa (Spain) and others.

Materials made of extruded polystyrene foam or polyurethane foam, although they have very good thermal insulation properties, are not fireproof: expanded polystyrene belongs to the group of highly combustible materials (G4), and polyurethane foam belongs to the group of moderately or slightly combustible (G2-G3). At the same time, fibrous heaters are non-combustible (NG).

The material was prepared by Alexander Levenko.

The definition of a warm contour follows from its name. If to speak plain language, then the thermal circuit is the circuit of the house that retains heat and is subject to heating.

What is the thermal circuit of the house

The thermal circuit of a house made of glued laminated timber should be installed, taking into account all the features of the Russian difficult climate - dampness, Cold winter, wind. Every builder, if he is a professional, will say that great importance must be attached to the thermal circuit. If technologies were not followed or material of dubious quality was used, no matter how good the walls were, such a structure will bring you many problems.

Agree that you do not want your house made of timber to be ventilated and cold, no one wants the house to be high humidity. Of course, when contacting us, you do not have to worry about this. Our wooden houses are not afraid of such problems.

What is actually included in the thermal circuit?

First, it is the foundation, including the basement.

Second, there are walls. Glued laminated timber - one of the best building materials, the walls of houses from it do not crack and are not blown.

Third, there are windows. Windows can be both wooden and plastic. The most important thing is that the windows are reliable. It should also be noted that glued beams have an important mission here. After all, glued beams are subject to minimal shrinkage. Deformation of windows in houses made of glued beams does not occur. They retain reliably heat, they are an important part of the thermal circuit.

Fourth, these are the doors. As in the case of windows, doors can be placed as tightly and correctly as possible.

The final component is the roof, as well as interfloor ceilings and internal partitions.

The erection of a thermal circuit is a basic package of the scope of construction work. Upon completion this stage, the house becomes a full-fledged structure, requiring only interior decoration and organization of the functioning of communications.

The thermal circuit consists of several required elements:

Foundation;

Walls;

Roof;

Window;

Cover partitions.

The thermal circuit is closed by installing windows and doors, which contributes to the formation of a microclimate in the premises of the house with a stable temperature and normal humidity necessary for high-quality finishing work. After the construction of the thermal circuit, the house reaches the stage of readiness at which, if necessary, the construction site can be “frozen” for long time without damage to the home.

ROTENSTEIN builds houses exclusively according to the closed thermal circuit method. Namely, insulating the roof and installing windows and doors. These items are already included in the price of our houses.

In the construction of the roof, only dried wooden beams. This allows you to cover and insulate the roof immediately, and also eliminates the deformation of the structure. And the installation of windows and doors makes it possible to suspend work, for example, for the winter period, excluding the ingress of precipitation into the house.

With particular scrupulousness, our specialists approach the installation of windows, because they often cause significant heat loss. Depending on your preferences, you can choose two-chamber plastic windows(it is possible to choose any shade of color coating), or put wooden double-glazed windows premium class. Whole the lineup windows is of exceptional quality, which our customers have already appreciated. Rotenstein houses are equipped with metal entrance doors with a safe lock and with two sealing circuits, which in very coldy eliminates the formation of perspiration inside doors. This solution reduces the need to design a vestibule, as well as to install an additional "internal" entrance door.

The terms for the construction of a closed thermal circuit in our company range from 4 to 8 months. As well as the cost, the terms are fixed in the contract. And are subject to revision only if it is impossible to carry out work due to weather conditions. We strictly adhere to the masonry technology and all building codes without exception, therefore, if frost occurs during work, construction is suspended until spring. During this time, the object is conserved using the unique Wienerberger technology, which does not allow the influence of atmospheric conditions on the structure.

The thermal contour of the house is the contour of the building, within which heating is organized. To ensure competent, reliable and efficient heating, it is important to correctly complete the project, taking into account the climatic and geographical features of the area, the location of windows and doors. Use only high quality construction and Decoration Materials, comply with construction technology. During construction wooden house it is important to choose the appropriate parameters of timber, the diameter of the log and the cross section of the timber.

The main elements of the thermal circuit

The foundation and basement lead to 20% heat loss of the total. It is important to correctly perform waterproofing and insulation of the base. Waterproofing will be performed horizontally and vertically with the help of coating compositions or rolled (pasted) materials. It is possible to insulate the basement inside and / or outside, as well as the floor from the side of the house or from the side of the basement.

Similar Finishing work prevent the negative effects of moisture, frost and temperature changes. They will protect against the formation of condensate, cracking, deformation and destruction of the foundation, the appearance of rot and mold on the walls of the house and the foundation, freezing of the basement.

The walls of the house must be strong and have desired thickness. Yes, for permanent residence you need to choose a log with a minimum diameter of 240 mm and a bar with a section of 150x150 mm. wooden walls be sure to caulk and insulate with safe material. Suitable option will become jute or acrylic sealant. The better to insulate a house from a bar or log, see.

When installing and finishing a log house, it is important that the walls of the house are airtight, and the materials are tightly adjacent to each other. Otherwise, cracks and bridges of cold will form, through which heat will escape, and wind will begin to enter the house and cold temperature, drafts will appear.

The roof is another important element of the thermal circuit. It is made according to the “pie” principle and includes several layers, including vapor barrier, insulation, waterproofing, lathing and counter lathing. Only then the roofing is laid.

Secondary contour elements

• must be installed correctly, especially in wooden houses. Here they require preliminary arrangement of the casing, which will exclude the deformation of the window or door structure during the shrinkage of the building. It is important to carefully insulate doors and windows so that there are no gaps and gaps between the wall and the structure box;
• Interfloor floors and interior partitions require insulation if the house will be used for living all year round. For a wooden house, they also choose safe and environmentally friendly materials that will not violate the naturalness of the wood and the atmosphere of the building;
• The entrance group also has importance when arranging a thermal circuit. It includes a vestibule, pantries and dressing rooms, a hall and rooms that follow the vestibule. It is important to properly design this room, arrange doors and windows. Without a vestibule and intermediate rooms, heat losses increase several times!

The heating circuit does not include terraces and verandas, open balconies and porch, attached garages and carports. However, insulated garages are already included in the heated circuit system. The thermal circuit affects the quality, reliability and durability of the structure. The MariSrub company competently and efficiently performs the insulation of each element of a wooden house.
