Connecting the battery to the heating system. Connection diagrams for heating radiators in a private house: features and principle of operation of different options. Where is the supply pipe, and where is the "return"

It is important for every person that their housing be comfortable and warm, especially considering that our climate is rather harsh. When building a house from a bar, it is imperative to insulate the outside. This is the only way to achieve a good microclimate at a time when frosts rage outside the window. In this case, you can use a beam, the thickness of which will be less than 40 cm.

However, here you will have to spend a little money, because the problem of thermal insulation cannot be solved by sealing cracks and caulking. In severe frost, the timber can freeze directly. As a result, it becomes necessary to insulate the house from a bar from the outside, since this one is the most effective.

Advantages of warming the house from the outside

What you need to consider when insulating the walls of a timber house

First of all, use the right insulation;
be able to correctly estimate the thickness of the thermal insulation material;
laying should be carried out strictly according to technology;
it is necessary to carry out all necessary waterproofing actions;
to protect the log house from the ultraviolet radiation factor and so on.

External insulation can be equipped in several options:

with the help of a hinged ventilated facade;
with polyurethane coating.
with foam insulation.

No. 1 - Hinged ventilated facade

Warming with this method is one of the best options, because it has a number of advantages:

fairly quick installation;
a different choice of material for cladding, including rack profile, lining, siding, wooden facade board, porcelain stoneware and so on.
excellent heat and sound insulation;
the service life is approaching 50 years;
finishing materials can have a variety of colors;
significant reduction in heating costs;
the facade is resistant to atmospheric phenomena;
the displacement of the “dew point” beyond the outer wall is provided.

Scheme of a hinged ventilated facade

Warming technology

A layer of insulation is attached to the outer walls, after which it is closed with a decorative finish.

No. 2 - Laying insulation under the siding

Attention! If mineral wool is used as a heater, then a diffusion membrane should be used to protect it from moisture. It is a perforated film that is able to pass evaporation to the outside, but does not allow atmospheric moisture to be absorbed into the insulation. If fiberglass or polystyrene is used, then they will not need moisture protection.

No. 3 - Polyurethane foam spraying method

This method has the following advantages:

This method is used for thermal insulation of the foundation, walls and basement of the house. It is quite popular during the installation of insulation of the outer walls of timber houses.

Finishing wall cladding

Sheathing a log house with plastic siding

To sheathe a house from a bar outside, it is advisable to use wooden boards, the thickness of which will be at least 25 mm. Also, they should be made of larch, pine or oak. In this case, an important parameter will be fulfilled, in which both the cladding and the walls will breathe better.

Wood plank finishes let the walls breathe

Important! During the installation of the cladding, special slots for ventilation should be created at the lower and upper edges of the facade. To prevent rain or snow from falling behind the facade, special visors can be mounted on the cracks.

In the next article we will look at - which insulation is best suited for this type?

Timber houses are warm, comfortable and energy efficient. They quickly heat up and retain heat, however, despite this, effective thermal insulation is an important issue that confronts the owner of the house. Why is it necessary to insulate a house from a bar 150x150 and how to do it? Consider all the options for thermal insulation of a timber cottage outside and inside.

Why insulate a house from a bar?

The construction of log houses in Russia has a long history. These buildings were rightfully considered the warmest and most comfortable. For another 30-40 years, such houses were built only from natural timber in the form of round or semicircular logs. The thickness of the timber reached 30 cm, and given that dry wood has excellent thermal insulation parameters, it becomes clear why timber structures were not insulated.

The main heat loss of a house from a bar

Today, 150x150 material is used to build a house from a bar. Such houses are environmentally friendly and comfortable, but their heat-preserving properties leave much to be desired. Competent insulation outside and inside will help to correct the situation and make the house warm.

Thermal insulation of a house from a bar from the inside

In central Russia and the southern regions, a house made of timber 150x150, which was not insulated, as a rule, does not freeze through. But living in such a house is uncomfortable. It is also worth noting that over time, the structure shrinks, cracks and cracks appear in the structure, as a result of which heat losses increase many times over. The internal insulation of a house made of timber can be carried out with various materials, which at the same time can serve as a finish. Such heat-insulating materials include cork insulation, “warm plaster”, etc.

Internal insulation has some disadvantages:

loss of usable area due to the installation of insulation;
a layer of thermal insulation hides wood walls;
condensation in the house due to a change in the dew point;
mold and wood decay.

Internal wall insulation with mineral wool

For these reasons, the owners prefer to insulate houses from a 150x150 bar from the outside. Thermal insulation can be provided for by the project and carried out immediately after the construction of the house. You can also insulate a cottage or a country house that has been in operation for a long time.

Interventional thermal insulation

Insulation of a house from a bar begins during the construction process, when interventional insulation is laid between the wood. 1-3 years after shrinkage of the structure, the walls of the cottage need caulking. Natural eco-friendly materials are used as interventional thermal insulation:

Moss. It has a thermal conductivity coefficient of up to 0.045 W / (m C), has aseptic properties, allows walls to “breathe” and protects wood from moisture and decay.

Hemp and linen tow. Thermal conductivity parameter up to 0.049 W / (m C). The material is resistant to moisture, provides reliable caulking of cracks and cracks.

Jute. Jute insulation is available in the form of strips. It is convenient to use, but the cost of jute is much more expensive than other materials for interventional insulation.

Jute - interventional insulation

Thermal insulation between the crowns is mounted using a special technology using thin spatulas and spatulas. This is a laborious process, but without high-quality caulking of the walls, it is impossible to proceed with external insulation.

The choice of external insulation

Warming a house from a bar 150x150 from the outside has the following advantages:

creation of a comfortable microclimate in the cottage;
lack of accumulations of moisture and condensate;
the usable area is not reduced;
the walls are ventilated, the house "breathes".

When choosing a material for external thermal insulation of a timber structure, it is necessary to give preference to heaters with good heat-retaining properties, durable, moisture resistant, and having a long service life.

The most popular insulation for timber houses are:

Mineral (stone) wool

Heat insulators based on mineral wool and basalt fraction have excellent heat saving performance and affordable cost. Also, the advantages of mineral wool include:

environmental friendliness, the material does not contain resins and toxins;
fire safety, mineral wool does not support combustion;
breathability, the walls of the house "breathe", condensation does not form;
a wide range of insulation, mineral wool is available in slabs and rolls of different thicknesses.

Wall insulation with mineral wool

A significant disadvantage of mineral wool is high water absorption. The insulation absorbs moisture and eventually loses its thermal insulation properties. Mineral wool can be used for thermal insulation of the roof and walls of a house made of 150x150 timber when creating an effective hydro-barrier.

Styrofoam and extruded polystyrene foam

Synthetic materials based on polymers with excellent heat-saving characteristics and minimal hygroscopicity. Polyfoams and XPS have the following advantages:

light weight, the insulation does not load the structure;
minimum water absorption;
low cost.

Numerous disadvantages of synthetic heaters do not allow their use for thermal insulation of the walls of timber cottages:

low environmental friendliness;
combustibility and release of toxins during combustion;
some types of insulation are the habitat of rodents.

Thermal insulation of the foundation and blind areas

Styrofoam and extruded polystyrene foam slabs for log houses 150x150 are used for thermal insulation of the floors of the first floor, basement and foundation. When insulating these structures, environmental parameters are insignificant, but low hygroscopicity (less than 0.05%) is very important.

Sprayed polyurethane foam (PPU)

Liquid insulation PPU polyurethane foam is sprayed onto the heat-insulated surface using special generators. The insulation forms a dense porous shell without seams and joints, which does not absorb moisture and passes air well. The thermal insulation qualities of polyurethane foam are superior to the best heaters - mineral wool and polystyrene. At the same time, the PPU layer does not exceed 3-5 cm. Sprayed thermal insulation can be used for all structures: foundation, walls, basement, roofing, ceilings. Polyurethane foam is used for insulation outside and inside the house.

Advantages of PPU thermal insulation for a house made of timber:

no harmful toxins, chemical neutrality;
do not change the basic properties of wood;
low flammability and fire safety;
reliable insulation of interventional seams and sealing of cracks;
excellent adhesion to wood and other materials;
protecting the timber from decay.

The disadvantage of polyurethane foam is its high cost, so it is preferred to combine it with other types of thermal insulation.

How is the insulation of a house made of timber?

Regardless of the chosen heat-insulating material, a house made of timber 150x150 and wood structures of other sizes must be prepared for insulation. Preparation consists in eliminating cracks and treating the timber with an antiseptic, fire and bioprotection. For old houses, additional fastening and strengthening of windows and doorways is carried out.

Insulation of a house from a bar outside

Mounting the heat insulator on the walls is as follows:

A crate is attached to the prepared and processed wall - bars 20x20 or 15x15 mm. The fastening of the crate is carried out using self-tapping screws or nails. The pitch of the crate is 0.5-0.7 m. A vapor barrier, for example, isospan, is laid under the crate. The film is overlapped and fixed with a crate.

Installation of thermal insulation is carried out on the finished crate. The insulation is laid between the racks of the second tier and attached to the wall with self-tapping screws. Additionally, it is recommended to use glue for outdoor work, which is applied to the insulation board.

Windscreen installation. The windproof film is laid on the thermal insulation and fastened with wooden counter-battens, which replace the reinforcing mesh used to insulate stone houses.

Cladding installation. Various materials can be used as finishing for a house made of timber: block house, wall paneling, facade slabs, thermal panels, etc. The choice of materials for external cladding depends on the preferences and financial capabilities of the owner.

Features of insulation of individual elements of timber houses

Thermal insulation of floors is performed with PSB-35 foam. Previously, a waterproofing film is laid on the logs. A cement-sand screed is laid on top of the insulation and the selected floor covering is laid. When installing the "warm floor" system, PE pipes are mounted in the screed according to the selected scheme.

Insulation of the floor of the 1st floor of EPPS

The roof of a house made of timber 150x150 is insulated with mineral wool slabs, which are attached between the rafters. From the side of the roof, the thermal insulation is covered with a membrane, and from the inside - with a waterproofing film.

If the house has 2 floors or a heated attic, then it is necessary to insulate the interfloor ceilings. To do this, vapor barrier films are used, on which loose insulation is poured into the interfloor space or rolled mineral wool is laid.

Insulation of the floor of the 2nd floor with mineral wool

The foundation, basement and plinth are insulated with foam plastic by gluing and attaching the plates to vertical surfaces. It is best to insulate the base immediately after its laying and waterproofing.

Heat saving in a house made of timber

In addition to internal and external insulation, a house made of timber must comply with the principles of energy efficiency. Elements of energy efficiency are incorporated into the construction of a log house at the design stage. The most popular and inexpensive energy efficient solutions:

Solar pipes. Pipes with a diameter of 30-50 cm are located on the roof and receive solar heat, which is directed inside the house using a set of mirrors. Sunlight diffused inside the room illuminates and heats.
Energy saving windows. The most heat-retaining are low-emission double-glazed windows that let short sunlight into the room and do not emit long-wave radiation emitted by heating devices.
Recovery ventilation. A heat exchanger built into the natural or forced ventilation system that delays the leakage of warm air.

Energy saving in a house made of timber 150x150

Competent and efficient insulation and the introduction of energy-saving technologies will make a house made of 150x150 timber not only comfortable for year-round living, but will also reduce heating costs. It is better to entrust the development of insulation projects and the installation of thermal insulation to professionals who will carry out a thermal calculation and determine the required thickness of the insulation, install it and provide a guarantee for thermal insulation work.

Today we will talk about the insulation of a house from a bar. If a person has lived all his life in Khrushchev or in an ordinary brick house, then he most likely does not represent all the charm of living in a wooden dwelling, just as they have no idea about caring for them.

One of the frequently asked questions about this concerns the fact that many do not know whether it is necessary to insulate a log house from the outside. In fact, wooden buildings can be very warm, especially from a log house, so external insulation is not always an urgent need. Thermal insulation largely depends on the thickness of the material and the density of the joints between the elements.

According to the norms of SNiP for wooden houses of permanent residence, the thickness of the timber for construction is needed at least 200 mm. If the building is used only as a summer cottage, then a material with a thickness of 150 mm will be enough. But if you buy such housing for year-round use, then the external insulation of the house simply needs to be done.

At the same time, even a 200 mm beam will not save if the connections between the beams are made incorrectly and gaps remain. There are also some drawbacks of the material that can lead to cracks and cracks over time: if the drying is poor, the profiled timber can deform, forming gaps in the joints, and the glued one is more prone to cracks from prolonged use, since it absorbs moisture well.

Therefore, the thermal insulation of a house from a bar becomes relevant in such cases:

It is planned to update the appearance of the facade or change it - sheathe it with other material (most often PVC panels), which would simultaneously protect the wooden facade and complement the exterior design.
There is a need to reduce heating costs.
Cracks appeared in the old facade, which is why the house does not keep warm.

Features of thermal insulation of a wooden house

In order for thermal insulation work to be useful, and not just provoke spending, you need to figure out how to properly insulate a house from a bar from the outside before starting to lay the insulation:

If it is planned to finish with thermal insulation immediately after construction, then it is advisable to wait 1-1.5 until the timber is completely dry and shrinks.
If there are gaps and cracks in the facade, then they are pre-sealed with wood putty, mounting foam, and jute fiber rope.

We also do not forget about the treatment of the wooden surface with antiseptics and antipyrines.
The most ideal insulation for a wooden facade is one that provides a dense thermal insulation layer. This must be taken into account when choosing.
It is better to sheathe a wooden house with light materials, otherwise the walls and foundation will not withstand the additional load. Therefore, for these purposes, PVC panels, block house or lining are more often chosen.

How to insulate houses from a bar?

Let's look at the options for insulation for wooden buildings, which are located in the list by popularity, and at the same time find out how to insulate a log house from the outside using each of the materials:

Ecowool is applied using a special technique by wet spraying (there is also a dry blowing and manual method, but this one is simpler and more convenient). A 5–10 cm spray ball is enough (the thermal conductivity of ecowool is 0.032–0.041). The layer is leveled along the crate and is dried, after which it is possible.

Mineral wool is produced in the form of plates. For insulation under siding, a plate thickness of 50 mm will be sufficient (its thermal conductivity is 0.036). It is mounted using dish-shaped dowels.

Polyurethane foam is sprayed with a special PPU gun with a tank in protective clothing and a mask. Spray thickness can be adjusted. It is better to make 2 uniform thin layers of 5 mm each than one uneven one. The thermal conductivity of such a material is 0.023-0.041, depending on the deposition density.

Expanded polystyrene boasts thermal conductivity of 0.038-0.041. It is provided in plates of various thicknesses, but products with a thickness of 5 cm will be enough for us. Installation is carried out with special glue and mounting dowels.

The technology of external insulation of walls made of timber

For wooden buildings it is better to use, that is, when installing the crate and insulation, it is necessary to leave a small gap for the subsequent installation of the sheathing. Finishing plaster is rarely used in this case, and only if polystyrene foam or polystyrene foam is used for thermal insulation.

The crate on a wooden house for the subsequent laying of thermal insulation and finishing is always made from an ordinary bar with a section of 50/50 or 50/60 mm on a prepared surface, that is, after sealing the cracks, impregnating and marking.
The cells between the bars of the crate are filled with insulation according to the technology corresponding to the material. Since it is planned to install a ventilated facade, do not forget to lay a diffuse membrane over the thermal insulation, and then nail additional bars on top of those already installed.
Now you can begin the installation of finishing materials - a block house, lining or PVC panels. To do this, use nails or screws. Start by installing the lowest panel, which is installed with the spike up. Self-tapping screws are screwed into this spike. Thanks to this, the mount will be hidden from the influence of the external environment, which also looks more aesthetically pleasing.

If it is important for you how to insulate a house from a bar from the outside, then you can not save on materials and choose polyurethane foam, which provides a solid dense layer of high-quality thermal insulation. But in most cases, a dense ball of ecowool will suffice, followed by a thick block house finish.

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

Features of warming a log house from the outside

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

Fortunately, these days there is a wide variety of educational videos and additional material that will make the set of upcoming events easier and faster. If you have the desire and time, you can insulate your room in the best possible way. So, first things first.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

vapor barrier

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

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

Mounting the frame for effective thermal insulation. Laying thermal insulation

In order for the end result of the insulation of the walls of a log house to be as successful as possible, pay attention to such a mandatory procedure as mounting the frame. As a frame, you can use high-quality boards with a width of 100 millimeters and a thickness of 40-50 millimeters, which are mounted on the wall vertically on the edge. The distance between the boards should not be less than the width of the insulation.

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

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

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

Laying the second layer of the frame

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

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

Ready-made heaters

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

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

Built from a wooden bar, the house actually breathes, providing a healthy microclimate to the space inside.

A well-caulked facade often does not need additional. However, it is carried out in order to save and save the energy used for heating.

In addition, cladding and effective insulation are one of the most relevant ways to repair a building that is no longer new.

Facade preparation

Warming is carried out according to the principle of a hinged facade. In choosing the most suitable material for this material, the householder often listens to the recommendations of friends and acquaintances.

Before starting work in the outer wall, everything will have to be repaired with high quality.

If the house is new, then it is necessary to wait at least a year, as they will appear after it shrinks.

In the old building, all corners and walls are carefully checked. The holes found are sealed with tow or hemp, which will require a chisel. It is advisable to have several of them in different sizes.

Cracks in the timber can be filled with a special compound - wood sealant. Glued laminated timber does not need caulking.

Material selection

After the completion of the restoration work, you can think about choosing a suitable insulation.

Most often, or is used as it.

Modern foam plastic has its improved version - extruded polystyrene foam. It is characterized by higher strength, even over time it does not crumble into fragments and granules. Ordinary Styrofoam collapses from time to time. Also, the improved type of material is distinguished by its.

How to insulate a house from a bar outside?

Such a heater mineral wool well ventilated. Due to this property, it does not lose its working qualities even when wet (it absorbs moisture well).

When choosing a material for warming a wooden structure, the features of finishing materials must be taken into account, thanks to which they can breathe like wood. This is of great importance.

The working properties of wood should not be violated, otherwise the qualitative physical characteristics of the dwelling may change. Therefore, more often the choice falls not on polystyrene foam, but on mineral wool.

The process of warming a house from a bar

How to correctly calculate the required thickness of the material for insulation

Before purchasing the material, it is required to calculate the required amount of mineral wool. Of no small importance is the thickness of the insulation.

Too thin is not only a violation of technology, but also sweating and weeping walls inside the building during the cold season. Excessively thick material is fraught with unreasonably high costs. When working, it is important to observe the following provision: the dew point from the wall is displayed strictly in the insulation.

For this reason, the wooden facade is insulated only from the outside.

You can not do your own, rather complicated calculations, and not order them from professionals, but refer to the requirements of a special SNiP, which defines all the necessary indicators for each specific zone.

It also states that if the wall has a thickness of up to 15 centimeters, then for mineral wool as a heater, a thickness of 5 centimeters is sufficient. A material of 10 centimeters will be too massive.

To calculate the thickness of the insulation, you can use a simple folk method:

If the winter temperatures do not fall below 20 degrees below zero, then with a thickness of 20 centimeters, one layer of 5-centimeter mineral wool boards will be required.
If the winters are colder, and the temperature often exceeds 20 degrees, two layers of mineral wool insulation are used.

Warming outside. Work progress

Suppose we have decided on the choice of material, and we know how thick it should be. All subsequent work is carried out according to the well-known template for mounting a hinged facade. This is a well known technology.

You have to do the following manipulations:
