At what temperature should the façade be insulated? Is it possible to insulate external walls in winter? Is it possible to leave an unfinished wet façade in winter?

Of course, it’s better to think about insulating your home in advance, for example, in the summer or spring, but not everyone remembers this. Having come to their senses on the eve of the onset of cold weather, people are faced with a great rush in construction companies and patiently wait for their turn. In addition, there are some features of facade insulation in winter, which depend, first of all, on weather conditions. Installation is complicated due to dampness and low temperatures, which is not in the best possible way affects the time of work and this nuance also needs to be taken into account.

The answer to the question whether it is possible to insulate a house in winter is more likely positive than negative, but you should know the features of the technology and take into account the choice of materials. The only difference between carrying out work in the warm and cold seasons is the weather and possible precipitation. When choosing suitable materials and methods of winter insulation of buildings, preference is given to those that will not be affected by either temperature changes or high humidity. There are certain rules that should be taken into account when carrying out installation in winter:

the optimal temperature range for reinforcement, gluing slabs and plaster is not lower than +5 C 0, for some materials limits up to -5 C 0 are acceptable;
humidity should not exceed 65%, optimally if it is warm and dry outside, then adhesive mixtures they will dry quickly and the insulation work will be completed much faster;
wind strength is important both for the safety of workers and for working with decorative plaster, which, with strong gusts, dries faster than usual, and this does not have the best effect on the final result.

Failure to follow all these rules will result in poor quality work. The insulation will not fulfill its direct tasks, or the material will become unusable quickly enough and will have to be replaced.

Methods of winter insulation technologies

Not only the quality of work, but also financial savings depend on the choice of insulation method, materials and design. What thermal insulation technologies exist?

Use of dry processes

“Dry” insulation is a universal method of thermal insulation that can be performed in any weather. The technology used for its implementation uses compositions that exclude the presence of water, liquid adhesives, mastic, etc. In this case, the fastening of insulating materials is carried out using hardware and self-tapping screws.

The most common option for the dry process is the installation of basalt slabs or foam plastic into a prepared wooden or steel frame along the entire facade of the building. The insulation layer on top is covered with a windproof membrane. Buildings of any type are insulated in this way: made of brick, blocks or wood.

Insulation with porcelain stoneware or stone slabs requires mounting on brackets. Such thermal insulation has significant weight, which puts forward special requirements for the materials from which the building is constructed. These are mostly brick houses with a solid foundation.

The advantage of traditional “dry” insulation is that it is economical; it does not require the use of expensive materials and highly qualified workers. It is quite possible to carry out the process yourself, having previously studied the main nuances of the work.

Insulation using the “wet facade” type

The “wet facade” technology is more common in construction companies than the “dry” process. The method consists of installing thermal insulation boards on the wall using dowels or anchors. Then they are covered with adhesive and plastered. Due to the lightness of the materials used, the “wet” method can be implemented on buildings of any type; it does not require calculations load-bearing capacity designs.

The disadvantage of a “wet” facade is that it cannot be used at temperatures below +5 C 0. Also, a similar method is not applicable for frame and wooden structures. Compared to other insulation technologies, it is more labor-intensive and time-consuming. Before installing the insulating material, the walls of the building facade must be perfectly smooth and free of dust and dirt.

The modern materials market has simplified the task of performing “wet” insulation in winter and offers the purchase of various anti-frost additives that allow installation work to be carried out in frosts down to -15 C 0.

Selection criteria and types of winter insulation

For a long time, expanded clay concrete and foam concrete served as the main materials for insulating facades in winter. Then glass wool began to be used, and only with the development of construction technologies did many other materials appear that cope well with thermal insulation. Each material has its own characteristic advantages that determine their choice.

Mineral wool. Excellent for insulating facades. It has many advantages: fibrous structure, high vapor permeability, non-flammability, and it is inexpensive. The facade insulated with mineral wool is able to “breathe”, which prevents the formation of fungus and mold. The material is suitable for all types of structures. Mineral wool is mainly used in “dry” processes.
Expanded polystyrene. It is one of the most budget-friendly materials for insulating facades. It is light, airtight, and easy to work with. In parallel with its advantages, the material has a number of disadvantages. Under the influence sun rays it ages, so it needs to be covered with primer, paint or cladding. Due to the fact that foam plastic does not allow air to pass through well, it cannot be used for thermal insulation of wooden houses.
Thermal panels. The material performs two functions at once: cladding and thermal insulation. Design and content may vary. Minslabs, polystyrene foam, cellulose, etc. can be used as an insulating layer, and cladding can be decorative plaster, metal, metal-plastic. The design can be assembled in the form of puzzles and conventional fastenings with self-tapping screws.
Warm paint. Initially, the material was intended for use in the space sector, but over time it became in demand in construction. It's all about filling the paint. It contains microscopic glass spheres, inside of which there is a rarefied space. The binding elements are latex, acrylic, silicone or a mixture of them. A 1 mm layer of paint is enough to provide protection as much as 2.5 cm from mineral insulation.
Izolon (foamed polyethylene). Available in soft rolls several millimeters thick. Often used in “dry” processes. Acts as a supplement to the main insulation of the facade with foam plastic in winter. Foamed polyethylene can be mounted anywhere in the frame: on the wall or under the sheathing. Isolon is vapor-proof and should not be used in the same structure with mineral wool.

When choosing a material for facade insulation, pay attention to the type of structure, region of residence, insulation properties and your financial capabilities. But it is best to consult with specialists who will determine exactly which thermal insulation option is suitable in a particular case.

Nuances of insulating the facade of a wooden house in winter

The insulation of wooden buildings requires special attention. Due to the fact that wood is natural material, it is subject to the influence of natural phenomena and weather conditions. The selection of facade insulation in winter is carried out based on their protective properties. There are certain restrictions when carrying out work in the cold season.

Polystyrene foam used as insulation on the outside must be immediately covered with protective materials, because with severe freezing and excessive moisture, it loses its properties and may simply collapse.
Carrying out the “wet” process in winter is only possible with “preservation” of the facade. Construction scaffolding is installed over the entire area of the wall, onto which the film is stretched. It turns out to be a kind of greenhouse, inside of which the building is located. Thus, the insulation maintains a positive temperature even in frosty conditions.
When laying insulation, natural drying and shrinkage are taken into account wooden house over time. If the building is new, then thermal insulation is carried out only after three years. old house can be insulated at any time.

For a wooden house, they usually choose a material that has permeability and can remove moisture and steam from the walls. These are mineral wool, polystyrene foam, ecowool (wet spraying). All these insulation materials practically do not absorb moisture, allow vapor to pass through and retain heat.

In addition to insulation, you need to prepare:

wooden blocks for arranging the sheathing;
waterproofing film to cover a wooden wall;
wind-waterproofing membrane for covering thermal insulation;
construction stapler and tape for nailing the film;
self-tapping screws;
screws with fungi;
metal mesh;
finishing.

Insulation of the facade of a wooden house from the outside in winter is carried out in several stages.

Prepare the walls for insulation. They must be smooth, clean and treated with antifungal agents. After treatment, the walls should dry well.
To prevent moisture that forms on the insulation from penetrating into the wood, the walls are covered with a waterproofing film. It is spread over the entire surface and secured using a stapler with metal staples. Each edge should overlap the previous one by 15-20 cm and be secured with tape.
The next stage is the construction of the sheathing. To lay the insulation in one layer, you will need 50x50 mm bars. They are attached to the wall vertically using self-tapping screws. The distance between the bars is 4–5 cm less than the width of the heat-insulating sheets.
Insulation is laid between the bars end-to-end and secured using “fungi”.
A wind-waterproofing membrane is attached to the sheathing on top of the thermal insulation. The edges are overlapped and nailed with a stapler.
To protect the insulation from rodents, you can attach a metal mesh over the membrane.
Mainly used as a finishing layer vinyl siding. First, slats with a cross section of 30×50 mm are screwed onto the frame using self-tapping screws. Fasteners are secured to them with screws, and then the siding is snapped onto them.

Insulation of the facade of a wooden house

Foam plastic previously coated with decorative plaster can also be used as an external facing finish.

Usually, internal thermal insulation of a wooden house is not done, but if there is such a desire, then expanded clay granules are used, mineral wool or sheet materials.

Before laying insulation interior walls are treated with agents that prevent combustion and rotting processes.
A wooden beam sheathing is mounted on the load-bearing walls. It must correspond to the height of the interior space.
After installing the frame, insulation is laid. It is cut to the height of the wall, the width should be slightly wider than the distance between the wooden blocks.
Thermal insulation is fixed between the bars and the wall with anchors. Wooden lining will look harmonious as a cladding.

For additional thermal insulation, you can insulate the basement of the house. Expanded clay is most often used, and besides, this work can be done on your own, without the involvement of paid specialists.

Features of working with a ventilated facade

The design of a ventilated facade is considered the most optimal for installation in winter time year. It consists of a rigid frame attached to the wall, insulation and facing material. Due to the fact that the cladding is located at a certain distance from the facade, ventilation is ensured and the impact of weather conditions is reduced to zero.

The most common materials are polystyrene foam and polyurethane foam. They are inexpensive, retain heat well, and do not rot or collapse over time. Mineral wool and basalt insulation are also often used.

A ventilated façade can be installed in any weather. The sheathing is mounted on the wall in increments of 30 cm. Thermal insulation boards are laid between the bars, which are attached to the wall with “fungi”. The top of the insulation is covered with a special fabric, onto which another sheathing is mounted. The finishing cladding is attached to the last frame. At this stage, the arrangement of the ventilated facade can be considered complete. As you can see, there are no difficulties in the work, so anyone can insulate a house, even without experience.

The stability of buildings is determined by the reliability of the foundation, and a comfortable room temperature depends on the effectiveness of thermal insulation. Temperature changes and humidity gradually destroy concrete. To ensure the durability of buildings and maintain a favorable microclimate, the base and other parts of the structure need to be insulated. Experts say that it is better to insulate the foundation of a house for the winter before the onset of cold weather. To reduce heat loss, it is important to protect problem areas using modern materials.

Is it advisable to insulate the foundation of a house for the winter?

It is not always possible to complete the construction of a building before the cold weather begins. Starting work in the spring, quite often builders complete the construction of the building before the first frost. However, it is too early to move in, because there is no thermal insulation.

When novice developers ask whether it is possible to insulate walls outside in winter, professionals give a positive answer, paying attention to the following insulation methods:

outer. External thermal protection prevents destruction of the foundation and main walls from the effects of temperature fluctuations and high humidity. Thermal insulation made on the street side allows you to move the dew point closer to the insulation, which helps maintain the strength of the box;
interior. Thermal insulation of the walls and basement of the building, performed on the living premises side, ensures a favorable temperature in the home during the winter season. However, the issue of external thermal protection of walls remains open. In its absence, structures gradually collapse as a result of natural processes.

Builders focus on the need to insulate the external structures of the building, which to a greater extent exposed to natural factors.

All types of foundations used for the construction of residential buildings require thermal insulation

The result of correctly performed thermal insulation measures:

preventing heat leaks. In most cases, they arise through insufficiently insulated parts of the building;
reducing the impact of frozen soil on the foundation. Deformation processes occurring in the soil cause cracking;
reducing the cost of heating the room. Properly selected thermal insulators slow down the cooling process;
stabilization of room temperature. Modern insulation materials make it difficult for cold to penetrate;
providing protection against condensation formation. The use of effective insulation prevents temperature surges;
no cracks in waterproofing materials. The elastic heat insulator absorbs soil pressure;
increasing the service life of the foundation. At normal humidity and temperature, the concrete mass is not saturated with moisture;
preventing the development of microorganisms. Dampness caused by high humidity promotes the development of mold.

By using insulation materials with correctly selected characteristics, as well as adhering to the requirements of the technology, it is possible to carry out work on thermal insulation of a building from the street side. In this case, work can be performed as if positive temperature, and when negative.

It is important to follow the rules of insulation design and use effective insulation materials

What materials are used to insulate a house in winter?

Among the many building materials, builders prefer the following insulation materials:

expanded clay. It is a lightweight, porous granule produced by firing clay at high temperatures. The peculiarity of expanded clay is its environmental friendliness. It is harmless to others. The material is resistant to negative temperatures and is used for thermal insulation of buildings;
polystyrene foam This thermal insulator is popular in the construction industry. Carrying out work using it does not require increased costs due to the low cost of polystyrene foam. The material is securely attached to the base with glue and holds well due to its low weight. Weaknesses– damage by rodents and fire hazard;
mineral wool. This is a traditionally used insulation. Provided that it is installed correctly and reliable protection It can provide thermal insulation to the room from absorbing moisture. When performing thermal insulation measures in the basement part of the building, moisture insulation of mineral wool should be ensured;
penoplex. This material is also known as expanded polystyrene. It is characterized by a long service life, environmental friendliness, and reduced hygroscopicity. The strength properties of penoplex are much higher than those of polystyrene foam. The heat insulator has low thermal conductivity and high resistance to natural factors.

In terms of efficiency, the external thermal insulation of a house is superior to the internal

When thinking about using an effective heat insulator, you should consider performance characteristics and properties of building materials:

specific gravity. Thermal insulation properties increase with decreasing density;
ability to conduct heat. Thermal conductivity is characterized by a special coefficient;
breathability. The structure of the material must allow the escape of moist air;
resistance to open fire. Fireproof materials allow you to avoid problematic situations;
frost resistance. Does not allow the insulation to crack when the volume of moisture increases as a result of freezing;
strength. To maintain integrity under mechanical loads, increased strength properties are required;
moisture resistance. To use insulation in areas with increased humidity, water resistance is important;
duration of operation. The use of durable thermal insulators reduces the cost of building repairs.

The given characteristics are the main ones. However, a number of properties should be taken into account:

ease of cutting for installation;
damage by mice;
sound insulation level;
fixation method;
harmlessness to others;
ease of delivery.

By comprehensively assessing the performance characteristics of building materials, you can make the right decision.

Insulation protects the room from cold penetration

Is it possible to insulate a wooden house from the outside in winter - recommendations from professionals

When choosing a material for insulating a wooden structure, pay attention to the preservation of its properties as a result of natural influences. If necessary, it is allowed to carry out thermal insulation work in winter, but there are certain restrictions.

In particular, professional builders give a negative answer when novice developers ask whether it is possible to leave the foam exposed for the winter:

the material is destroyed under the influence of ultraviolet rays;
thermal insulation properties worsen when frozen and over-moistened;
If open flames are used close to each other, a fire may occur.

Sometimes situations arise when a decision is made to make a wet façade in winter. Do not forget - preserving a wet facade for the winter is a serious task.

It allows:

prevent cracking of the heat insulator;
increase the durability of insulation;
preserve the structure of the material.

Let's consider the features of individual events.

Using correctly selected thermal insulation materials and following technological recommendations, you can reliably insulate a building with outside

Is it possible to insulate a house in winter from the outside of the basement of the building?

Proven technology allows for thermal insulation bottom part buildings, following the given sequence of operations:

Prepare a pit around the perimeter of the building.
Place moisture insulation in the trench.
Pour in expanded clay.
Waterproof the insulation.
Pour sand and concrete.

Doing the work yourself is not difficult.

Is it possible to insulate walls outside in winter with penoplex?

It is allowed to insulate the walls and base of the building with penoplex. To insulate the walls, stick polystyrene foam and plaster the surface.

The foundation insulation algorithm is as follows:

Dig a trench around the foundation.
Apply bitumen to the surface of the base.
Stick on penoplex.
Waterproof the insulation.
Fill the pit and make a blind area.

Penoplex provides high level thermal insulation.

If you need to insulate the outside of a wooden building in winter, remember about changes in the properties of materials under the influence of natural conditions

Wet façade in winter – technology

At temperatures down to minus 5 degrees Celsius, a wet façade can be installed in winter. Technological sequence of work:

Clean the surface.
Secure the heat insulator.
Reinforce the surface with mesh.
Apply plaster.
Paint the walls.

To protect the facade, use a special primer.

We insulate a wooden building from the inside of the building

Insulation of a building from the inside cannot be compared in effectiveness with external thermal insulation, which protects the base and walls from freezing. Let's consider the features of using various heat insulators.

Using expanded clay for internal thermal insulation of the base

Application of expanded clay for interior work allows:

thermally insulate the base of the building;
insulate the floor of the room.

Sequence of actions:

Form a moisture-wicking layer.
Pour in expanded clay.

The gap between the floor and the expanded clay layer promotes moisture removal and ventilation.

Using mineral wool to insulate the inside of the base

Perform thermal insulation with mineral wool as follows:

Make grooves at the bottom of the walls to collect moisture.
Waterproof the surface.
Cut and secure the mineral wool.
Moisture-proof the mineral wool.

Due to its increased hygroscopicity, mineral wool needs reliable protection.

Conclusion

It is preferable to carry out construction work on thermal insulation at positive temperatures. At the same time, the technology makes it possible to insulate a building in winter using modern insulation materials.

Insulation (thermal insulation) in winter period a private home becomes possible if you follow the rules provided by winter technologies and with the right approach to choosing insulation for the facade of the house. In resolving the last issue, the resistance of products to seasonal temperature changes and high humidity is taken into account.

Work in the cold season

Is it possible to insulate the facade in winter?

Basic rules for thermal insulation in winter:

the temperature permissible for working with materials in winter is above +5°C, less often -5°C;
relative humidity should be less than 65%;
the speed of wind gusts affects the safety of work;
strong wind speeds up the drying process of the plaster composition, which negatively affects the quality of the final result.

Any violation of thermal insulation technologies in winter is always followed by a distortion of the result specified by the manufacturer.

Failure to comply with the rules has a negative impact on service life. So, in one winter, materials can become unusable and need to be replaced.

As a result, insulating the facade in winter has its pros and cons. The disadvantages are mostly related to improper drying. water compositions due to difficult weather conditions. And the advantages are that the walls become insulated from the effects of cold and moisture.

Options for winter insulation technologies

It is possible to insulate the facade of a house in winter only in accordance with certain rules. Which technology to use depends on the chosen insulation and finishing material.

"Dry" method

In winter, as a rule, preference is given to “dry” technology. This is due to the fact that during the installation process the use of materials that contain any amount of water is practically excluded. To fix the insulation, metal fasteners or so-called mushrooms (plastic dowels for insulation) are used.

Dry method technology

Several types of heat insulators are more popular as insulation.

Polystyrene foam and polystyrene foam have excellent thermal insulation properties. The first one practically does not absorb moisture and does not allow steam to pass through. Expanded polystyrene has zero performance in the same moments. Installation of polystyrene foam is characterized by a large amount of debris, since the material tends to crumble. The insulation is afraid of fire, ultraviolet radiation, acetone, turpentine and drying oil.
Polyurethane foam has the lowest thermal conductivity coefficient among other insulation materials. It is applied by spraying, so additional fixation does not require the use of fasteners.
Mineral wool does not deform due to fluctuations in temperature and humidity, does not burn.
Basalt and stone insulation do not rot and are not afraid of open fire. Experts consider them the best for winter insulation.

Order facade works includes:

preparation of the base;
lathing device;
insulation gasket;
covering the structure with a membrane sheet.

This technology allows you to insulate walls built from block products, brick or wood in winter.

The process of insulation using the “dry” method often involves the installation of a ventilated façade. An empty space is created between the insulation and the facing material, which ensures constant ventilation.

This rids the base of excess harmful moisture. This method is more economical than the “wet” one. Among other things, the reason is the opportunity to refuse the services of professionals and do everything yourself.

Insulation using “wet facade” technology

Most construction companies prefer a “wet facade”. It differs in that the thermal insulation is fastened by anchor bolts and plastic dowels. In addition, an adhesive solution is applied to the insulation, and the finished coating is covered with a leveling layer of plaster.

Wet façade technology

This solution is suitable for any walls, except wooden houses and buildings frame type. The result is lightweight, so foundation load calculations are usually not required.

Despite the justified advantages, “wet” technology is inferior in some respects:

in winter, it is necessary to observe the minimum thermometer reading at which it is possible to use a particular material;
the installation process is more labor-intensive and takes longer;
walls require preliminary preparation: cleaning from protruding elements, dirt and dust;
leveling the base;
primer treatment.

Manufacturers, taking into account the possible use of materials in winter, offer to purchase special additives. They allow you to reduce the threshold of acceptable temperature for work to -15°C.

Selection criteria and types of winter insulation

If we talk about the choice of material for facade insulation, then modern market provides many options.

Previously, foam concrete and expanded clay mixed with concrete mortar. Later, glass wool was used for insulation, and today the number of insulators has increased significantly.

Below are popular thermal insulators, as well as their main characteristics and advantages.

Mineral wool and its modifications have good vapor permeability and do not rot. The insulation is breathable. This fact allows you to prevent the occurrence and development of fungus or mold. It is used primarily for insulating facades in accordance with “dry” technology.

Foam plastic (expanded polystyrene) It is easy to handle and is a strong barrier to wind and moisture, but is sensitive to the sun. Its scope does not extend to wooden facades. Surface treatment required protective compounds.

Thermal panels used not only as insulation, but also as an aesthetic facing material. The first include mineral insulation, including expanded polystyrene (foam plastic) or cellulose, and for the second - decorative types plasters, metal-plastic, metal products.

Warm paint manufactured using different binders. It contains microscopic components in the form of glass spheres with rarefied space. For comparison, 50 mm of insulation corresponds to a 2 mm thick coating of thermal paint. She combines two useful features: insulation and aesthetics.

Izolon used in the process of insulation using “dry” technology. In winter, it is used as an additional reinforcement of the main insulation, which creates excellent double protection. The material is vapor-permeable, so it is not combined with mineral wool and its analogues, but other heat insulators are chosen.

The choice of insulation is influenced by the climatic conditions of a particular area, as well as the financial situation of the buyer.

Before making a final decision, it is recommended to seek advice from specialists in the construction industry.

Nuances of insulating the facade of a wooden house in winter

Houses made of wood essentially require the use of protective materials, since the log house is easily exposed to any natural phenomena.

If you decide to insulate the facade in winter, then you need to take into account some nuances:

polystyrene foam must be immediately treated with protective compounds to avoid its rapid destruction;
the choice of “wet facade” technology is appropriate only if a thermal curtain is created;
wooden buildings can be insulated only after their complete shrinkage, which occurs during the first three years.

As for the insulation, it must be a barrier to moisture, “breathe” and retain heat. Mineral wool, polystyrene foam, ecowool or polyurethane foam cope with these tasks.

Foam insulation

Properly carried out insulation can protect the house from the cold and reduce the cost of heating the premises. IN developed countries In cold climates, numerous energy saving systems have been used for a very long time, allowing to reduce heating costs several times.

However, it happens that for some reason the work was not completed in warm time year, and the owner is faced with a choice: leave the house without insulation until spring or try to finish the work now. Is it possible to insulate a house in winter, and what materials are used for this?

In winter, work becomes difficult not only due to low temperatures, but also due to precipitation and high humidity. Rain and snow will not allow the adhesive solution or plaster to dry, so you can’t work with all insulation materials.

We have to look for workarounds and installation methods that will not be affected by cold weather.

Insulation of a ventilated facade

The easiest way to insulate a house in winter is to install a ventilated façade. This is a structure consisting of a rigid frame attached to the wall, insulation and facing material, which is attached without the use of an adhesive solution.

As a result, the cladding is located at a short distance from the wall, providing protection from rain and other adverse weather conditions, and at the same time the facade is vapor-permeable.

The use of high-quality insulation material allows us to minimize heat loss and provide good sound insulation. At the same time, the rooms will not be stuffy, there is no threat of mold or mildew due to high humidity.

Insulation work can be carried out at any temperature with your own hands, and even a novice builder can do this.

Which material to choose?

Today, a number of materials are used for insulation, but not all of them are suitable for work in winter, and not all of them are safe in terms of their environmental properties.

The most common and popular options:

Expanded polystyrene and polyurethane foam (PPU insulation). These materials have very low thermal conductivity and low hygroscopicity, and tolerate both high and low temperatures.

They do not rot over time and do not cake; their price is quite low. However, they also have disadvantages; both are combustible materials, so such houses are characterized by poor fire safety;

Mineral wool and basalt insulation- more popular material options for ventilated facades. They may cost a little more, but their thermal insulation properties are also excellent. The insulation principle is similar to that used in clothing insulation, such as the Valterm 100 winter insulation. Since air conducts heat very poorly, the breathable material provides good ventilation and at the same time protects against the cold.

Important! Basalt fiber slabs can retain their shape for decades, and they do not burn. We can say that basalt wool is best option for winter insulation of the house.

How to insulate walls?

A ventilated façade can be installed at any time of the year, so this type of system will give a positive answer to the question of whether it is possible to insulate the walls outside in winter.

For most materials, a layer of insulation no more than 5 cm thick is sufficient - it will protect the house even from very severe cold weather.

The work is carried out in several stages, step by step instructions looks like this:

A vertical sheathing is placed on the walls, the pitch of which should not exceed 30 cm. To create it, you can take wooden beam measuring 40x50 mm, attach it using dowels. This is a very important stage of work, since the type of finished coating will depend on the installation of the lathing.

The design of the ventilated facade system provides for the possibility of additional insulation of the external walls of wooden, brick house. This technology is quite relevant in the context of rising prices for fuel and electricity.

Insulation of a suspended ventilated facade of a house

Let's take a closer look at the diagram of the insulation system for the external walls of a wooden or brick house, the functions of insulation for walls, and the basic requirements for the technology of performing the work.

When insulating the walls of a wooden or brick house according to this scheme, the main temperature difference occurs in the thickness of the facade insulation, and the outer surface of the load-bearing wooden or brick wall of the house even with severe frosts has a positive temperature. The outer wall does not experience significant temperature deformations. Due to the system of insulation of the external walls of the house, with the correct calculation of the thickness of the façade insulation and compliance with the installation technology, the service life of wooden and brick wall structures is significantly increased. In a facade insulation system between the insulation and the facing material, the air temperature, with good ventilation and quality thermal insulation, is equal to the external temperature. Thanks to the technology of insulating the walls of a wooden or brick house, in winter, frost does not form on the inner surface of the facade material. When calculating the thickness of the external thermal insulation of a brick or wooden house according to the proposed scheme, you should pay attention to the fact that the dew point, even in winter, is outside the outer wall of the building. The thermal insulation system of a building significantly reduces temperature fluctuations in a wooden or brick wall structure.

In practice, one often encounters the fact that when reconstructing old wooden or brick houses, customers refuse to use additional external thermal insulation. If in winter the outer walls of such a house are cold and damp inside, then in no case should additional insulation of the walls of the building be neglected during reconstruction. Such savings on insulation technology will lead to rapid deterioration of the interior finishing, and subsequent repairs will still not make sense without external thermal insulation. Of course, even after installing siding or other facade cladding material without insulation, wooden or brick walls will become drier and, as a result, warmer, but most likely this will not be enough.

A number of very stringent requirements are imposed on thermal insulation for insulation of a ventilated façade system. Facade insulation must be non-flammable and have high performance thermal insulation. Facade thermal insulation must withstand alternating sign temperature regime operation, have high vapor permeability. Materials for the external insulation system of a wooden or brick house must have high biostability and resistance to weathering.

For the technology of insulating ventilated facades of wooden and brick houses, we recommend using facade thermal insulation made from mineral basalt wool or glass wool from various manufacturers, correctly calculating its thickness.

Insulation with mineral wool is optimal choice for suspended ventilated systems of wooden or brick houses. Hydrophobized external thermal insulation based on basalt rocks is characterized by non-flammability, high thermal insulation properties, excellent vapor permeability, low water absorption, dimensional stability, and durability (over 50 years). Basalt thermal insulation - best choice for façade insulation system according to affordable price. To reduce the cost of the facade insulation system as a whole, the technology allows the use of thermal insulation consisting of two layers of facade insulation. The inner layer of insulation is made according to the scheme from low-density insulation (30-50 kg/m3), the outer layer of insulation with a density of more than 80 kg/m3. The total layer thickness is determined by calculation. Recently, manufacturers of basalt facade insulation have been offering thermal insulation for the outer layer of insulation, which can be used without additional wind protection. This also makes it possible to reduce the cost of insulation and increase the fire safety of wooden structures. One of the new thermal insulation products that has appeared on the market is two-layer facade insulation. A denser layer of thermal insulation is installed on the outside of the insulation façade structures wooden or brick houses, less dense - directly on load-bearing wall, since the soft layer allows the thermal insulation to better adhere to the unevenness of the insulated structure. Also, when insulating a ventilated facade, in order to reduce its cost, it is permissible to use a combined thermal insulation scheme made from mineral wool and fiberglass from various manufacturers.

Conclusion

Is it possible to insulate a house in winter? The answer is clear: yes. However, you need to know the basic technologies and rules of operation in the cold season in order for the system to be reliable and durable.

A ventilated facade will reduce heat loss many times, and it can be installed at any time. Other technologies require special equipment, however, they can also be brought to life.

The main task of external wall insulation is to save material resources on utility bills by retaining and concentrating more heat indoors. Once you think about whether it is possible to insulate external walls in winter, you should immediately study the main advantages of the procedure. In the most developed countries, similar energy saving actions have long been used, which can significantly reduce heat costs.

Working with a ventilated façade

This method of insulating a building is the simplest and most common today. We're talking about reliable design with a fairly rigid frame, which must be attached to the outer wall. The structure includes high-quality insulation and cladding material. In this case, there is no need to use adhesive solutions to attach the cladding.

The most important thing is to choose the right insulation. As a result, it will be possible to minimize heat losses. At the same time, very high-quality sound insulation will be ensured. Some citizens fear that in this case they will be too stuffy inside, but these are just assumptions that are absolutely not true. Another advantage is that even beginners in construction activities will be able to produce insulation. Work can be carried out at any time of the year.

Basic materials for insulation:

foam;
expanded polystyrene;
facade thermal panels;
basalt and mineral wool insulation.

In addition to selecting the material, builders should definitely study the main features of insulating external walls in winter and learn how to apply them correctly in practice. Each material presented above has its own thermal insulation and other properties, information about which must be studied carefully.

Main works

As mentioned above, installation of a ventilated facade can be done at any time of the year. Winter is the most difficult time to work due to the cold weather. Although when proper organization process, this circumstance will not become a problem. The most important thing is that nothing bad will happen to the material in sub-zero weather. Having figured out which insulation to choose in winter, it should be noted that a maximum thickness of sheets of materials of 5 centimeters will be quite enough. Such a layer will be able to protect the room from negative impact weather even in the most severe winters.

Wall insulation is a process consisting of several most important stages. First of all, vertical sheathing should be applied to the surface of the external walls. In this case, a small wooden beam attached with dowels can come to the rescue. The subsequent type of final coating will directly depend on this stage of work. The previously selected insulation is placed on the surface of the sheathing. Umbrella dowels are suitable for securing it.

On top of the insulation it is necessary to use a special type of fabric that protects the base materials from the negative effects of moisture. At the same time, the vapor permeability of the insulation is not reduced at all, because the protective fabric is characterized by the presence of a wind and waterproof layer. Then comes the stage of creating the so-called diffusion gap. To do this, the sheathing is applied again. Only after completing this stage can you safely begin installing the siding. As an alternative, you can give preference to other types of finishing coating.

Additional features of the work

During the insulation process, certain difficulties may arise. In many situations, thermal insulation in winter is made using extruded polystyrene foam, which is absolutely justified. The fact is that the presented material is resistant to a wide variety of materials and substances that are often used in construction. We are talking about acids, alkalis, dyes, alcohols, etc.

Experts say that even insulating a wet façade is feasible. However, the corresponding procedure becomes more complex and costly from a financial point of view. Many companies that offer their clients the “wet” method of insulation prefer to work exclusively during the warm season. This distinguishes them from experienced professionals who can cope with this task even in winter. True, they cannot do without the use of antifreeze additives. It is also difficult to create a warm outline around the entire construction site.

Let's sum it up

It should definitely be stated that insulating facades in the winter is possible and absolutely realistic. True, to achieve a positive result, it is imperative to thoroughly study the rules for using a specific type of insulation, installation technology and other nuances of the process. Only in this case will the system be as durable and reliable as possible. The easiest way to insulate a ventilated facade. There are other technologies. They involve the use of special technical equipment, but still allow you to achieve your goal.

For information

Extruded polystyrene foam has a strong, integral microstructure that looks like closed cells filled
gas molecules. This is a chemical substance with strong intermolecular bonds, which are tens of times stronger than in polystyrene foam. Individual cells are impenetrable because, unlike foam, they do not have micropores, which prevents the penetration of water or gas from an adjacent cell.

TeploStroyMontazh LLC - Is it possible to properly insulate external walls in winter?

Winter insulation of walls outside in Vladivostok and Primorsky Krai is CORRECT!

With the onset of autumn and then winter, feeling the first cold and shortcomings in the thermal insulation of their apartment or house, people rush to call and order wall insulation. But have you ever wondered - is it possible to insulate walls in winter?

In winter, it is impossible to insulate the walls of an apartment using the “plaster facade” type in most cases, based on our experience. Why? We will try to bring to your understanding the intricacies of winter wall insulation, which we have already encountered, and protect you from unscrupulous contractors who are “selling” you that winter insulation performed with 100% readiness is “good.” Let's take it in order.

So it's getting cold outside. When executing finishing works the plaster mortar freezes over the insulation, we don’t have time to smooth it onto the wall as it should. Window slopes in sub-zero temperatures will also not be able to be made efficiently and evenly. If there is a slight minus, then after laying the mortar on the wall, it still freezes, becoming covered with a pattern characteristic of winter. Very often an ice “crust” forms. This leads to subsequent peeling of the finish from the insulation. That is, this solution froze on the wall and did not gain strength. At the time of painting, the entire layer of thin-layer plaster is wound onto a roller.
“But there are antifreeze additives! “- some specialists who have never seen them will say. Yes, they allow a little extra time to apply and smooth the plaster. But then the plaster will freeze anyway. And as you know, the strength of the solution after it thaws drops by half. Also, very often efflorescence (marks on the wall, stains) from anti-frost additives may appear on the wall, which does not add any aesthetics to your wall, even at home or in an apartment.

SO WHAT TO DO?

Winter insulation of external walls from the company TEPLO STROY MONTAZH includes installation of the insulation itself and sealing of connections. Sealing is carried out with winter foam sealant. The first stage is enough to save you from problems associated with freezing. Since the “dew point” is transferred from the inner surface of the apartment (to the outer surface of the insulation), the house becomes much warmer, “fungus” and dampness disappear. With the onset of above-zero temperatures, our craftsmen begin the SECOND STAGE of insulation - plastering on the mesh twice, followed by painting. A huge advantage of winter insulation is that you live warm all winter and receive interest-free installments (since the work is carried out in two stages, the payment is divided into two parts). Don't wait for spring!

How to insulate the foundation of a house for the winter?

Is it advisable to insulate the foundation of a house for the winter?

It is not always possible to complete the construction of a building before the cold weather begins. Starting work in the spring, quite often builders complete the construction of the building before the first frost. However, it is too early to move in, because there is no thermal insulation.

When novice developers ask whether it is possible to insulate walls outside in winter, professionals give a positive answer, paying attention to the following insulation methods:

outer. External thermal protection prevents destruction of the foundation and main walls from the effects of temperature fluctuations and high humidity. Thermal insulation made on the street side allows you to move the dew point closer to the insulation, which helps maintain the strength of the box;
interior. Thermal insulation of the walls and basement of the building, performed on the living premises side, ensures a favorable temperature in the home during the winter season. However, the issue of external thermal protection of walls remains open. In its absence, structures gradually collapse as a result of natural processes.

Builders focus on the need to insulate the external structures of the building, which are more exposed to natural factors.

All types of foundations used for the construction of residential buildings require thermal insulation

The result of correctly performed thermal insulation measures:

preventing heat leaks. In most cases, they arise through insufficiently insulated parts of the building;
reducing the impact of frozen soil on the foundation. Deformation processes occurring in the soil cause cracking;
reducing the cost of heating the room. Properly selected thermal insulators slow down the cooling process;
stabilization of room temperature. Modern insulation makes it difficult for cold to penetrate;
providing protection against condensation formation. The use of effective insulation prevents temperature surges;
no cracks in waterproofing materials. The elastic heat insulator absorbs soil pressure;
increasing the service life of the foundation. At normal humidity and temperature, the concrete mass is not saturated with moisture;
preventing the development of microorganisms. Dampness caused by high humidity promotes the development of mold.

By using insulation materials with correctly selected characteristics, as well as adhering to the requirements of the technology, it is possible to carry out work on thermal insulation of a building from the street side. In this case, work can be performed both at positive and negative temperatures.

What materials are used to insulate a house in winter?

Among the many building materials, builders prefer the following insulation materials:

expanded clay. It is a lightweight, porous granule produced by firing clay at high temperatures. The peculiarity of expanded clay is its environmental friendliness. It is harmless to others. The material is resistant to negative temperatures and is used for thermal insulation of buildings;
polystyrene foam This thermal insulator is popular in the construction industry. Carrying out work using it does not require increased costs due to the low cost of polystyrene foam. The material is securely attached to the base with glue and holds well due to its low weight. Weaknesses - damage by rodents and fire hazard;
mineral wool. This is a traditionally used insulation. Provided that it is installed correctly and is reliably protected from moisture absorption, it can provide thermal insulation for a room. When performing thermal insulation measures in the basement part of the building, moisture insulation of mineral wool should be ensured;
penoplex. This material is also known as expanded polystyrene. It is characterized by a long service life, environmental friendliness, and reduced hygroscopicity. The strength properties of penoplex are much higher than those of polystyrene foam. The heat insulator has low thermal conductivity and high resistance to natural factors.

When thinking about using an effective heat insulator, you should take into account the performance characteristics and properties of building materials:

specific gravity. Thermal insulation properties increase with decreasing density;
ability to conduct heat. Thermal conductivity is characterized by a special coefficient;
breathability. The structure of the material must allow the escape of moist air;
resistance to open fire. Fireproof materials allow you to avoid problematic situations;
frost resistance. Does not allow the insulation to crack when the volume of moisture increases as a result of freezing;
strength. To maintain integrity under mechanical loads, increased strength properties are required;
moisture resistance. To use insulation in areas with increased humidity, water resistance is important;
duration of operation. The use of durable thermal insulators reduces the cost of building repairs.

The given characteristics are the main ones. However, a number of properties should be taken into account:

ease of cutting for installation;
damage by mice;
sound insulation level;
fixation method;
harmlessness to others;
ease of delivery.

By comprehensively assessing the performance characteristics of building materials, you can make the right decision.

Insulation protects the room from cold penetration

In particular, professional builders give a negative answer when novice developers ask whether it is possible to leave the foam exposed for the winter:

the material is destroyed under the influence of ultraviolet rays;
thermal insulation properties deteriorate when freezing and waterlogging;
If open flames are used close to each other, a fire may occur.

Sometimes situations arise when a decision is made to make a wet façade in winter. Do not forget - preserving a wet facade for the winter is a serious task.

It allows:

prevent cracking of the heat insulator;
increase the durability of insulation;
preserve the structure of the material.

Let's consider the features of individual events.

Using properly selected thermal insulation materials and following technological recommendations, you can reliably insulate a building from the outside

Is it possible to insulate a house in winter from the outside of the basement of the building?

Proven technology allows you to thermally insulate the lower part of the building, following the given sequence of operations:

Prepare a pit around the perimeter of the building.
Place moisture insulation in the trench.
Pour in expanded clay.
Waterproof the insulation.
Pour sand and concrete.

Doing the work yourself is not difficult.

Is it possible to insulate walls outside in winter with penoplex?

It is allowed to insulate the walls and base of the building with penoplex. To insulate the walls, stick polystyrene foam and plaster the surface.

The foundation insulation algorithm is as follows:

Dig a trench around the foundation.
Apply bitumen to the surface of the base.
Stick on penoplex.
Waterproof the insulation.
Fill the pit and make a blind area.

Penoplex provides a high level of thermal insulation.

If you need to insulate the outside of a wooden building in winter, remember about changes in the properties of materials under the influence of natural conditions

Wet façade in winter – technology

At temperatures down to minus 5 degrees Celsius, a wet façade can be installed in winter. Technological sequence of work:

Clean the surface.
Secure the heat insulator.
Reinforce the surface with mesh.
Apply plaster.
Paint the walls.

To protect the facade, use a special primer.

We insulate a wooden building from the inside of the building

Using expanded clay for internal thermal insulation of the base

The use of expanded clay for interior work allows you to:

thermally insulate the base of the building;
insulate the floor of the room.

Sequence of actions:

Form a moisture-wicking layer.
Pour in expanded clay.

The gap between the floor and the expanded clay layer promotes moisture removal and ventilation.

Using mineral wool to insulate the inside of the base

Perform thermal insulation with mineral wool as follows:

Make grooves at the bottom of the walls to collect moisture.
Waterproof the surface.
Cut and secure the mineral wool.
Moisture-proof the mineral wool.

Due to its increased hygroscopicity, mineral wool needs reliable protection.

Conclusion

Insulation of walls in winter using the “wet facade” type or is it possible to insulate walls in winter?

With the onset of winter, feeling the first cold and shortcomings in the thermal insulation of their apartment or house, people rush to call and order wall insulation. But have you ever wondered - is it possible to insulate walls in winter?

In winter, insulating the walls of an apartment using the “wet facade” type in most cases is not possible, based on our experience. Why? We will try to make you understand the intricacies of winter wall insulation, which we have already encountered, and protect you from unscrupulous workers who are “selling” you that winter insulation is “good.” Let's take it in order.

So it's getting cold outside. During the work, the plaster solution freezes, we do not have time to smooth it onto the wall as it should. And those who have “crooked” hands simply put it on the wall as if shovel. Window slopes cannot be done efficiently in sub-zero temperatures. If there is a slight minus, then after laying the mortar on the wall, it still freezes, becoming covered with a pattern characteristic of winter. Very often a “crust” forms. This leads to subsequent detachment from the insulation. Those. this solution froze on the wall and did not gain strength. At the time of painting, the entire layer of thin-layer plaster is wound onto a roller. This is also facilitated by the paint, which thickens more than usual in subzero weather. In other words, we paint the wall, and the plaster is wound onto the roller in the literal sense of the word. Let's face it, sometimes it doesn't work out.

“But there are antifreeze additives!” - some comrades who have never seen them will say. Yes, they give a little extra time for applying and smoothing the plaster. But then the plaster still freezes. Then there should be a long pause so that this frozen plaster gains strength. No one can stand this pause, and they won’t say so. And as you know, the strength of the solution after it thaws drops by half. Also, very often efflorescence (marks on the wall, stains) from anti-frost additives may appear on the wall, which does not add any aesthetics to your wall, even at home or in an apartment.

Another point about winter insulation is that frost often appears on the plastered surface. Similar to those on trees, but smaller, not so fluffy. And how to paint a wall? Brush or mitt? Yes, that’s what everyone does - with a mitten in most cases. But that doesn't change anything. Frozen water still remains in the pores of the wall. Therefore, you need to wait until the wall dries. Even if no peeling occurs during painting, then there is a high probability that the paint on the wall will begin to peel off. This describes the best case if the wall is thoroughly cleaned of frost and allowed to dry for about a week. And the wall is big. No one will clean the wall down to a centimeter. We only need responsible people like us, and we don’t have this desire (to clean the wall from frost or freezing rain).

There are also freezing rains in the winter. After which the entire wall is covered in frozen droplets. Imagine this on your wall that you plan to pay your own money for. Tough. And we know this too. What kind of guarantee for work is there... Simply wonderful.

Another feature of winter wall insulation is that there is often precipitation in the form of snow or rain (relevant in recent years, sometimes they even drew water from puddles in January :)). It is not possible to clean the wall perfectly for the same reasons as described above. So you have to wait until it goes away on its own. How long to wait? Not known, depends on the weather. Likewise, precipitation likes to accumulate in window niches. Those. In winter, snow (or rain) falls on the “window sill from the street side” and begins to melt. Accordingly, everything that melts flows along the wall, leaving a damp place and ice (sometimes it washes away the plaster - it depends on the intensity of precipitation), which also cannot be easily gotten rid of. You have to wait again until it dries. And while you wait, it may snow again and the same thing will happen. Great too.

Also in winter it can be simply cold outside. Holding a spatula in frozen hands and shifting from foot to foot, while receiving another portion of cold wind in your face, is no pleasure from the work - not everyone can do it. And when you’re cold, the job you’ve taken on doesn’t look so optimistic at all. I would like to warm up. And often it is impossible to bring forests to the house or behind the house by car due to snow cover.

Conclusion:

In any case, wall insulation in winter turns out poorly!

Not conscientious workers, they are everywhere, it doesn’t bother me. They just smear and paint, without delving into the subtleties, and leave with their money... And then everything cracks and peels, and you are left with nothing.

Therefore, if you want to insulate a wall in winter, and for the work to be done efficiently, you need to bypass all these obstacles; it takes many times more time, which is very difficult and beyond the power of many “cranky-handed workers.” Also, you should not be confused by the phrase “WORK WITHOUT WARRANTY” at your own risk.

This is why we do not insulate walls in winter, but you can sign up for wall insulation in the spring now and you will be first in line.

But there are also cases when it is possible to insulate walls in winter if a thermal circuit is provided, i.e. a greenhouse made of tarpaulin, thick polyethylene, etc. Periodically, the greenhouse is heated to maintain a slight plus inside the circuit. This does not apply to the insulation of apartments. In a word, this is an increase in price, and by a lot. It's easier to wait for spring. It is also possible to insulate walls in winter if it is a ventilated facade, where there are no “wet processes”, i.e. works related to plastering.

Hydrophobizer (water-repellent impregnation) - an umbrella for the dacha! If you have country house, you can certainly be congratulated on the fact that you have become a true professional in all areas related to construction and repair. Insulate the house, connect the irrigation system, arrange an artificial pond, lay a path from one end of the site to the other, upholster the rooms with clapboards, treat them with an antiseptic - no problem! How are you doing with protecting your home? Traditionally in Rus' a lot of buildings are built from wood. But wood, as you know, needs constant care - it’s too capricious. It is porous and easily absorbs moisture. And in a humid environment, fungus, moss, algae and rot grow. And now, using the old proven method, you apply vitriol to the walls, cover them with varnish and paint, and protect them with antiseptics. But it rains or the snow melts in the spring, and you notice with horror that the paint has peeled off, the varnish has peeled off, and cracks have formed. Through them, moisture penetrates deeper and deeper, “ignoring” the protective layer of paint.

Eco-friendly Russian wooden baths

Warmth and humidity are the hallmarks Russian baths. The bathhouse was always located not under the same roof and not quite close to the living quarters. The most attractive places for a bath were on the banks of a river or lake, so that after a steam bath you could refresh yourself in a pond. This also justifies itself due to the frequent fires to which Russian baths have long been prone for some reason. Currently, bathhouses with swimming pools are very popular.

The history of the Russian bath goes back more than one century and its design has been brought to perfection in order to reliably retain heat in the bath and remove excess moisture. The best option to meet these requirements is wooden frame houses or bathhouses made of coniferous wood. Wooden walls have the excellent property of retaining heat inside and not disrupting normal air exchange. The choice of materials for construction should be taken very seriously. The tree must be dried, from the northern regions, preferably winter felling, because In winter there is practically no sap flow in the trees. Saunas made from sanded logs have better performance than saunas.

Collections of metal tiles Metal Profile or 3+3

For twenty years we knew only 3 collections of Metal Profile metal tiles. They have already become timeless classics. steel roofing, a familiar solution in suburban and interesting - in high-rise housing construction. But it's probably time to change something. In 2018, 3 more versions were released almost simultaneously. About everyone at once and about each series separately. Model range of metal tiles Metal Profile Starting with the first metal tiles, you can trace the evolution of the development of the roofing direction of the steel craftsman. This is shown in the main technical specifications. Monterrey Model has the honor of being the first in the triumphant series of steel roofing now leading Russian manufacturer. The S-shaped profile immediately attracted attention due to its features similar to ceramic tiles. Wave height 15mm and pitch 350mm are standard parameters for metal tiles. SuperMonterrey The wave height increases to 21 mm with the same step. For the first time, the manufacturer makes it clear that the ceramic imitation profile turns into an independent roof with its own feature. It is expressed in a virtual expansion of the roofing covering. Metal Profile can be called the founder of the 3D format.

Dismantling of floors

Dismantling of ceilings may be required when carrying out redevelopment or reconstruction construction work. The complexity of this task lies in the fact that the work must be carried out taking into account the need to preserve everyone safe and sound load-bearing structures buildings. Inept dismantling of the ceiling can lead to cracks in the walls or other parts of the facility, and cause irreversible consequences, including the collapse of the entire building. It is strongly not recommended to dismantle ceilings on our own! This is dangerous due to the destruction of the building and serious injury to you. Contact professional builders, only they will be able to carry out this work in compliance with all safety standards and requirements technical regulations. Serpukhov-Stroy specialists have extensive experience in dismantling floors in buildings made of any material, any number of floors and purpose. We will professionally produce partial or complete dismantling ceiling, interfloor and basement floors at industrial, commercial and household use turnkey. Qualified experts will develop a project, choose the optimal demolition strategy, and calculate technical parameters. .

Insulating walls outside in winter: methods and materials

Properly carried out insulation can protect the house from the cold and reduce the cost of heating the premises. In developed countries with cold climates, numerous energy saving systems have been used for a very long time, allowing to reduce heating costs several times.

However, it happens that for some reason the work was not completed in the warm season, and the owner is faced with a choice: leave the house without insulation until spring or try to finish the work now. Is it possible to insulate a house in winter, and what materials are used for this?

Is it possible to insulate a house in winter?

We have to look for workarounds and installation methods that will not be affected by cold weather.

Insulation of a ventilated facade

As a result, the cladding is located at a short distance from the wall, providing protection from rain and other adverse weather conditions, and at the same time the facade is vapor-permeable.

Scheme of a ventilated facade

Insulation work can be carried out at any temperature with your own hands, and even a novice builder can do this.

Which material to choose?

Today, a number of materials are used for insulation, but not all of them are suitable for work in winter, and not all of them are safe in terms of their environmental properties.

The most common and popular options:

Expanded polystyrene and polyurethane foam(PPU insulation). These materials have very low thermal conductivity and low hygroscopicity, and tolerate both high and low temperatures.

They do not rot over time and do not cake; their price is quite low. However, they also have disadvantages; both are combustible materials, so such houses are characterized by poor fire safety;

Mineral wool and basalt insulation– more popular material options for ventilated facades. They may cost a little more, but their thermal insulation properties are also excellent. The insulation principle is similar to that used in clothing insulation, such as the Valterm 100 winter insulation. Since air conducts heat very poorly, the breathable material provides good ventilation and at the same time protects against the cold.

Important! Basalt fiber slabs can retain their shape for decades, and they do not burn. We can say that basalt wool is the best option for winter insulation of a house.

Cottage with ventilated facade

How to insulate walls?

A ventilated façade can be installed at any time of the year, so this type of system will give a positive answer to the question of whether it is possible to insulate the walls outside in winter.

For most materials, a thick layer of insulation is sufficient no more than 5 cm– it will protect the house even from very severe cold weather.

The work is carried out in several stages, step-by-step instructions are as follows:

Vertical lathing is placed on the walls, the pitch of which should not exceed 30 cm. To create it, you can take a wooden beam measuring 40x50 mm, attach it with dowels. This is a very important stage of work, since the type of finished coating will depend on the installation of the lathing. The installation plane is leveled using a building level;

The selected construction insulation is placed in the sheathing - in this case, basalt or mineral wool slabs. Each mat of mineral wool or other material is attached to the wall using umbrella dowels; at least two of them are needed for each slab;

Important! There is no need to insert any vapor barrier materials between the insulation and the wall.

The insulation on top is covered with a special fabric - a wind-waterproof layer. such a membrane will protect the mineral wool from moisture and caking, but at the same time will not reduce its vapor permeability.

Moisture formed as a result of the temperature difference will be removed from the insulation, and moisture from the outside will not be able to penetrate it. The easiest way to attach the fabric to the sheathing is with a construction stapler and staples; such fastening will be quite reliable;

Installation of membrane and second layer of sheathing

A second layer of sheathing is installed on the membrane to create a diffusion gap. This is done in order to provide a gap between the insulation and the outer covering. It must be at least 20 mm. The photo shows how the wall should look at different stages of work. Instead of wooden sheathing, it is often installed metal profile. It is much stronger and lasts longer;
After this, you can install siding or any other finishing coating. The walls will look beautiful and at the same time will be well protected from both cold and water.

Very soon there will be a noticeable improvement in the microclimate in the room, as heat loss is reduced many times over. Since this insulation option can be carried out in any weather, for winter it is one of the most practical and easy-to-implement solutions.

Insulation of a wet facade

Is it possible to insulate walls outside in winter using thermal insulation materials and plaster? It is possible, but the technology will be much more complicated and more serious financial investments will be required. Therefore, if possible, it is better to carry out such work in the warm season. If you still have to work in winter, then there are two options for insulation.

Use of antifreeze additives

Conventional building mixtures can only be used at positive temperatures of at least 5 degrees. Otherwise, they will simply stop drying, and the structure will turn out to be unreliable.

However, now there are anti-frost additives that allow construction work to be carried out even at sub-zero temperatures, usually down to -8, and sometimes down to -15 degrees. Their use will allow you to not interrupt work even in severe frosts, and the solution will quickly harden, ensuring proper strength and reliability.

This method also has significant disadvantages. First of all, this high price additives Insulating all external walls will require quite a lot of material, and this will lead to a significant increase in costs.

In addition, not only low temperatures, but also precipitation and high humidity prevent the adhesive mortar and plaster from hardening. Rain, snow and strong winds may eventually cause the coating to crack, and the work will still have to be redone in the spring.

Arrangement of a warm circuit for work

Another affordable, but somewhat labor-intensive option is to create warm circuit around the construction site, which will bring the temperature to a level acceptable for any construction work, and at the same time protect the wall from the adverse effects of weather. With its help, you can insulate facades both in rainy autumn and cold winter.

Thermal contour on the facade of the building

Thermal circuit (popularly "warm") is created as follows: around scaffolding a layer of reinforced film is installed that can withstand gusts of wind and keep cold air out.

Installed inside the circuit heat guns taking into account their power according to the heating scheme. Thermometers are placed on the walls so that the temperature can be maintained at approximately the same level. We have to organize 24/7 duty, so that it does not change and does not fall below 0.

Wet façade insulation scheme

After installing such a system, you can install insulation on the walls according to the same principle as in the summer:

The walls are leveled and thoroughly cleaned of remnants of old coating, dust and dirt. The smoother the wall, the more reliable the insulation layer will be. It is convenient to use expanded polystyrene (foam plastic) as a material; it is very easy to process and provides good thermal insulation;
Diluted in a bucket glue solution from a dry mixture and clean water. The mixture is applied to the foam board around the perimeter, leaving gaps to allow air to escape. The slabs begin to be glued from the corner, pressing them tightly against the wall;

Applying glue to foam board

The panels are additionally attached to the walls using special dowels with mushroom-shaped tips. They are attached in the center and in the corners for more secure fastening;

Scheme of additional fastening of foam plastic with dowels

Another layer of adhesive is applied on top of the insulation, and a reinforcing mesh is applied to it, which will become the basis for the future coating. It is laid from top to bottom, the joints should be overlapped. The mesh is completely “recessed” into the adhesive solution, and it is covered with another layer on top;

Fastening the reinforcing mesh

The solution must be allowed to harden, this takes about two days. All this time it is necessary to maintain a positive temperature. After the solution has completely dried, you can begin finishing and laying a layer of plaster.

Wet façade scheme

This is one of the options for insulating a house in winter, using the technology of creating a “wet” facade. The result will be no worse than in summer, but heating will inevitably require additional costs.

How to insulate a loggia in winter?

Insulation of the loggia in winter has to be carried out according to the same principle, but here it is much easier to carry out insulation. First, the loggia needs to be glazed, for which it is most profitable to use two-chamber plastic double glazed windows. All seams are treated with foam, this must be done especially carefully under the window sill. With the help of foam, all seams in the walls and near the floor are closed.

A wooden sheathing is installed on the walls, between which slabs of foam plastic or other insulation are inserted, which are then nailed with special fasteners. They are covered with a layer of foam rubber or other moisture-proof material on top, and after that you can install any finishing coating, be it lining or siding.

Such insulation will allow you to turn the loggia into a warm and comfortable room, which can easily be turned into an additional living room. However, you need to remember that insulation work is carried out on all surfaces: not only on the walls, but also on the floor and ceiling.

Conclusion

A ventilated facade will reduce heat loss many times, and it can be installed at any time. Other technologies require special equipment, but they can also be implemented.
