Is it possible to insulate the facade of a house in winter? Proper insulation of a ventilated facade in winter. Use of expanded clay for internal thermal insulation of the base.

When to insulate a house from the outside? Greetings, dear clients and simply readers, the company is with you and today we will answer this seemingly simple question.

When to insulate a house from the outside? - answer

What time of year is it better to order insulation of the facade of a house?
The answer to this difficult question is not clear-cut. And there are several reasons for this:

1) The most obvious reason is the presence Money. No matter how the performers tell you that you need to insulate now and not later, if you don’t have money, there’s nothing you can do about it;

2) On the one hand, it is better to carry out insulation, like any other construction work, in dry, warm weather, it is convenient/easier for builders, but on the other hand, in a humid and cloudy period, unevenness and other flaws are better visible on the surface (wall), which are immediately visible can be corrected.

Any construction specialist will tell you that “construction” is seasonal work. and the price will vary significantly in different seasons. Therefore, the answer to the question “When to insulate a house from the outside” seems to be unambiguous at a superficial glance. Although there are companies that carry out construction work all year round and their price practically does not depend on the season.

A generally noticeable trend is that people think about insulation closer to autumn, and this is understandable, since electricity tariffs are steadily rising. By insulating your home, you will reduce heat loss and, accordingly, heating costs. This is definitely a profitable investment. Insulating a house is not only about preserving heat, but also against moisture (condensation) and mold. The benefit of foam insulation is additional sound insulation of the walls.
This is what happens in our company, we work all year round and the price does not depend on the season. We are not chasing speed and profit; our goal is satisfied customers. Our main activity is insulating the outside of houses with polystyrene foam, with high-quality sealing of seams.

Our company's specialists are professionally trained and have high-altitude tolerances. All work is carried out according to highest quality. Your façade will be well insulated at any time of the year.

can protect residents from the winter cold and reduce bills for heating rooms. In countries with an unpleasant climate, energy supply systems have long been introduced that can save several times on heat consumption.

However, work does not always go according to plan. Sometimes it is not possible to complete insulation in the summer. The owner is faced with a problem: is it worth finishing the work in the winter or is it better to postpone the finishing to the spring.

Work at such times is complicated not only because of negative temperatures, but also because of the high concentration of moisture in the air and frequent precipitation. Rain and melted snow prevent the glue solution and plaster from drying on walls of the building, therefore finishing with some insulating materials is impossible.

Figure 1. External insulation of a house in winter.

To ensure reliable insulation, it is necessary to use alternative installation methods that are protected from weather influences. Winter work is easier to carry out with the installation of a ventilated facade - a structure built from a durable frame fixed to the wall, insulation and cladding, attached without an adhesive solution.

Manufacturing technology allows you to arrange the finishing layer at a distance from the surface so as to protect it from rain and other aggressive weather conditions. At the same time, the façade becomes vapor-permeable. At there are pros and cons to insulating the facade in winter.

What methods allow you to carry out external insulation of a house in winter?

Correct method and quality thermal insulation insulation of a façade house allow you to reduce losses to a lower threshold and build decent sound insulation. At the same time, the rooms will not be stuffy, they will not begin to fill with spores - humidity is not a threat.

If you master the technology correctly thermal insulation ventilated facade, work can be carried out independently at any temperature, even without professional construction skills.

Wet processes at subzero temperatures

A wet façade is a component of a heat saving system (PPS or basalt wool) fixed to wall surface on the adhesive solution or by mechanical force (rarely used).

Above slabs reinforced with fiberglass mesh and covered with plaster. Usually the finish is painted and tiled for beauty. Decorative models already have acceptable appearance, but they can also be painted.

Advantage wet insulation– relatively low cost, variability design solutions(the facade can acquire individual features), ease of restoration and saving of usable space in the room. Resistance coefficient, heat transfer and other properties of the interlayer depend on the choice of material and its thickness.

Use of dry processes

When it is not possible to compensate for the effect of aggressive weather conditions on the treated surface, in case of dangerous temperatures forced to use “dry” processes.

All mechanisms that exclude the addition of water or the application of solutions, viscous adhesives and mastics for fixing materials can be considered suitable for operation.

The simplest option is basalt wool or polystyrene foam pasted over the facade of the building. Any brick, wood or block surface is processed using this technology. For installation use wooden sheathing or pendants. In a frame structure, cotton wool or polystyrene foam is initially installed in the base posts.

Features of a wet facade in winter

The use of technology is recommended only at favorable temperatures. The simplest version is the installation of a thick film along the outer perimeter of scaffolding mounted on the facade. If strong wind exposure is planned, then the use of reinforced film is allowed.

To increase the temperature in such a “greenhouse” they use heat guns. Significant heating is not required - it is enough to provide a favorable environment for facade plastering.

At what temperature should a wet façade be installed?

The situation in winter time is complicated by the presence of water in the fillers of adhesive and plaster substances. It freezes at zero temperature. Special masses contain relatively little water, so they can withstand lower thresholds, but within insignificant limits.

How to make a wet facade in sub-zero temperatures

Folk craftsmen advise adding salt to the mixture. The technology is not particularly effective: during installation and after finishing the cladding, the work looks decent and does not lose heat, but when the weather begins to improve, whitish stains form on the facade.

To provide high-quality insulation outside the house The following mechanism is better suited: the formation of a temporary thermal insulation contour. Work process:

1. Formation of forests. They can be assembled in the summer - there are no significant differences from the usual construction procedure.
2. A moisture-proof film is laid around the outer perimeter, and special thermomats are installed.
3. Heating units are installed in the work area - coal, gasoline or electric. Experts do not recommend using diesel heaters: when heated, soot is released and settles on the material to retain heat (this can make it difficult to adhere to the covering layer).

In this case, a separate microclimate is collected under the canvas. To lay external plaster, it is necessary to maintain a working environment of +8 degrees, and for the final stages of work +5 degrees is enough.

In the language of builders, such a contour is called a “warmhouse”. It is designed to create conditions suitable for installation, regardless of the season. It has other advantages:

• protection from precipitation;
• obstruction to the passage of rays;
• wind limitation;
• reduced exposure to humidity.

During the construction process, all characteristics are maintained at a stable level, which cannot but affect the final quality of the facade. To a small extent, the technology even provides comfort when working: if you drop a tool, you don’t have to go downstairs to get it.

In this way it is possible not only insulate gas silicate blocks and other facade materials, but also masonry, standard insulation. The method is also used in restoration, roofing and other external work. Its disadvantages: high price, duration and technological complexity. The cost of cladding increases by an average of 10%.

Using Modifiers

Over time, many modifiers have appeared on the market - substances that can improve the characteristics of the solution: increase frost resistance, etc.

The effect was achieved by eliminating water as one of the components of the solution. The connecting element is made using acrylic, converted at a partial level.

Interesting! Using Modifiers allows you to perform work in frosty weather (up to -15 Celsius), and the composition is also suitable for storage in cold conditions.

Some masters doubt the promises of the manufacturers of these modifiers. Your opinion about finishing the facade of the house They argue as follows:

• The processes of crystal formation in a mass protected from frost are not well understood. The veracity of claims requires research and practical verification;
• Modifiers cause “side effects”: adjustment of the quality indicators of the mounted facade, reduced durability of the structure, and a weaker ability to retain heat.

Is it possible to leave an unfinished wet façade in winter?

If work becomes so complicated in winter, then many people have a question: is it possible to freeze the process until warmer times. Decorative plaster - This is not only a decorative element, but also reliable protection of the insulation from external influences. It should be applied immediately after insulation, since many materials are not capable of long time withstand the external environment.

Expanded polystyrene vulnerable to sunlight - it cannot be left exposed to ultraviolet radiation for a long time, even in winter. EPS absorbs water minimally, but still absorbs it. If exposed for a long time, the insulation will get wet. PPS also refers to combustible materials. If you leave it open, you will have to worry about fire safety measures.

Household wool is not a flammable material, but has significant hygroscopicity. A wet sheet loses half of its useful characteristics. The impact of mechanical factors on each of the materials in winter time increases significantly due to wind, snow, rain, etc.

Important! It is logical that installing insulation and leaving the walls like that for the whole winter is not best idea. The material will not be able to retain heat, and the work will be in vain.

Methods for covering the area are also not very reliable. plastic film– it does not allow air to pass through, so condensation will begin to accumulate inside. Separate “breathable” hydro-windproof membranes are sold, but to cover the entire area with them you will have to invest a lot.

It is recommended to reinforce the slabs before the onset of cold weather, apply a protective layer of plaster and cover everything with a frost-resistant water-repellent solution. It is possible to use primer paint - it contains acrylic sand. And decorative work can be postponed until the weather warms up.

You need to understand that it is better to apply decorative finishing to the surface after the house has settled - so life time plaster will increase. If a wet façade is being installed in a newly built building, forced downtime can be effective.

Requirements for thermal insulation material

You should focus on the following characteristics:

• Good thermal insulation – thermal conductivity material should be very low. The effectiveness is indicated by the layer (modern polyurethane sheets are up to 20-30% more effective than polystyrene).
• Best before date. There's a championship here insulating the house goes to polyurethanes. According to statistics, they can last up to 60 years or more, which cannot be said about conventional fibrous materials.
• Protection from moisture and other aggressive influences. The facade, being outside, is exposed to wind, precipitation and temperature fluctuations, and sometimes to damage due to vandalism.
• Fire hazard. It is assumed that the correct façade has low flammability and does not contribute to the growth of flames. Using the right material increases the fire resistance of a structure and ensures the safety of all occupants.
• Susceptibility to biological influences. These are insects, rodents, microbes that live in environmental insulation materials (sawdust, mineral wool and others), however, standard industrial substances cannot be considered a guarantee of safety.
• Weight. The façade should not place an increased load on the wall and foundation. Also, materials with a large weight are not convenient for installation.

Advantages of winter facade insulation

Winter insulation is possible. Moreover, the procedure can be completed faster, since you do not have to wait for the walls to heat up and dry out - in cold weather this happens faster (the dew point moves outside).

Other benefits:

• Price;
• Light weight;
• Wide choose;
• Durability;
• Vapor barrier.

Disadvantages of winter facade insulation

The process also has its disadvantages and weaknesses:

• Temperature conditions;
• Air humidity;
• Excessive heat.

It is possible to carry out insulation in winter, although it is quite difficult. If the facade does not retain temperature well, it is recommended to insulate it. Despite the complexity of the process, winter finishing can be reliable and durable.

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?

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(). 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;

• – 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 Valterm 100 winter insulation. Since air conducts heat very poorly, breathable material provides good ventilation and at the same time protects from 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 Houses.

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 instruction as follows:

• Vertical lathing 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 installation plane is leveled using a building level;

• It fits into the sheathing - in 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 mineral wool from moisture and caking, but at the same time it 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;

• 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 metallic profile. It is much stronger and lasts longer;
• After this, you can install siding or any other finishing coat. 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 interfere with the hardening of the adhesive mortar and plaster, but also precipitation, and high humidity. 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 a warm loop around the construction site, which will bring the temperature to a level acceptable for any construction work, and at the same time it will protect the wall from the adverse effects of weather. With its help, you can insulate facades both in rainy autumn and cold winter.

Thermal circuit (popularly "warm") is created as follows: a layer of reinforced film is installed around the scaffolding, capable of withstanding gusts of wind and not allowing cold air to pass through.

Heat guns are installed inside the circuit, 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 round-the-clock 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;
• An adhesive solution from the dry mixture is diluted in a bucket 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;

• 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;

• 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;

• 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.

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 advantageous to use double-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 on top with a layer of foam rubber or other moisture-proof material, 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

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, but they can also be implemented.

In the video presented in this article you will find additional information on how to insulate a house in winter using ventilated facade technology.

When to insulate house facades: choose the time of year

Now, after another jump in energy prices, private houses have become an urgent need for millions of Ukrainians. After all, as calculations confirmed by practice show, if these thermal insulation works are carried out correctly, heating costs can be reduced by forty percent or more!

What and how insulation is done

In order to choose the right time of year for insulation, we will consider existing technologies for thermal insulation of homes. Let's first consider the option as the most popular. After all, improving the thermal insulation of walls immediately leads to savings in the fuel on which the boiler operates autonomous heating– gas, electricity or solid fuel.

Insulation of a private house is done in two ways:

• Using expanded polystyrene or polystyrene tiles.
• Using special thermal panels.

Insulation of the facade with polystyrene foam or polystyrene tiles

Consists of the following steps:

1. Preparatory work– sealing cracks in walls, leveling the surface, cleaning from dirt and old coatings.

2. Installation of tiles is done using special adhesives, and now mainly with polyurethane foam adhesives.

3. Wall reinforcement and finishing work - applying an adhesive composition to the tiles, then laying a plastic reinforcing mesh, then again applying a layer of glue and finally finishing walls (, plaster, finishing artificial stone etc.).

From the point of view of weather conditions, the most critical is the application of the adhesive composition. Polyurethane adhesives and facade adhesives allow operation at temperatures of –5 – +35 degrees Celsius.

Insulation of the facade with thermal panels

This method differs from the previous one in that the heat-insulating material is not glued to the facade, but is attached using a supporting frame. That is, after preparing the surface of the walls, a frame is mounted on them, and mineral insulation, moisture and vapor barrier are already attached to it. Then the whole thing is covered with metal sheets.

As can be seen from the description, this method is even less critical to the ambient temperature.

Insulation of apartments

This type of work is carried out similarly to the first method of insulating private houses. There are several differences:

• At the first stage, when preparing the walls, if the house is panel, then it is done;
• At the third stage of diversity in choice finishing materials No. Thermal insulation tiles are plastered, primed and painted with facade paint.

In principle, it is produced in a similar way.

So when is it better to insulate the facades of houses?

As can be seen from the description above, starting from March you can safely insulate houses and apartments. Moreover, in the summer, when high temperatures(and this is no longer uncommon) the adhesive properties of adhesive compositions will deteriorate (above + 35 degrees Celsius).

One more argument can be made in favor of spring - companies performing insulation work are not yet loaded with orders. This will have a positive impact on the quality of work and their cost.

The main task of external wall insulation is to save material resources on utility bills by preserving 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. This is about reliable design with a fairly rigid frame, which must be attached to external 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:

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

In addition to the selection of materials, builders should definitely study the main features of insulating external walls in winter period 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 if the process is properly organized, 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 special type fabric that protects basic 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 done using, 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's also difficult to create warm contour 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 positive result It is imperative that you 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.
