Is it possible to insulate the house with industrial insulation. Is it possible to insulate the walls outside in winter

Residential and non-residential buildings and premises in the "wet way", using wet processes, cannot operate in the winter period, since most materials for facade insulation can only be used at positive temperatures.

Our facade materials will help them bypass the "temporary downtime" and extend the construction season due to the WINTER facade adhesive for all types of insulation: Avangard Zima and Thermobond Zima.

Winter glue for gluing thermal insulation (basalt-based minplate, polystyrene foam - PSBS, extruded polystyrene foam) Avangard Winter and Thermobond Winter are indispensable materials for facade work at low temperatures.

The most acceptable working time with WINTER MIXTURES is at temperatures from -10 to +10 degrees Celsius.

But many builders, manufacturers of facade works and facade insulation works in the “wet way” are afraid to work with “winter mixtures” and treat them with distrust.

There are objective reasons for this.: fear of innovation - used to working the old fashioned way with familiar mat serials, ignorance of the product and its operation, bad experience with cheap winter mixtures,produced in a standard way for the main domestic producers, by adding salts to similar "summer" mixtures. The use of such mixtures leads to the subsequent protrusion of salt, which causes criticism from the Customers of the construction, and the construction workers, it is necessary to remove this salt, as it were, winter additive at their own expense.In addition to the "efflorescence" appearing outside, the mixture made by this method affects the technical characteristics of the materials and changes them for the worse (unlike the same analogue "Summer"), namely: increased porosity of the surface or structure in the section (which affects its strength -decrease!), delayed product strength development, corrosion of building reinforcement, failure in interaction with other polymer additives present in the mixture, which can automatically affect one or more technical indicators (for example, ADHESION may decrease, in other words, the ability of the product adhere/glue to the substrate, or plasticity, etc.). All this also scares off the end consumer (builder, construction customer).

The salt additive or its "work" in combination with other polymeric additives can lead to delamination of the facade mesh, which is indispensable for facade insulation work, because. used to create a reinforcing layer (in particular, this applies to facade glass meshes that have not passed the test and do not have the necessary certification (from RosStroy of Russia) for the use of this material for wall insulation in the “wet way”), which will lead to subsequent peeling from the glued insulation, wet plaster and creating the effect of "walking facade", "sail".

Our adhesives for winter temperatureswere developed according to a unique recipe, based on imported and domestic materials, which significantly reduced the cost of their production, and hence the price for the end user. In data production polymer adhesives for negative temperaturesapply exclusivelyimported winter additives (non-salt) and domestic fractional sand. So these materials, subject to the technology of their application, developed by the company's specialists, allow to avoid the problems inherent in "cheap" similarities of winter adhesives.

IT IS NECESSARY TO KNOW SOMEFEATURES OF APPLICATION OF WINTER BUILDING MIXTURES FOR WORKS AT NEGATIVE TEMPERATURES:

· Do not mix with water at temperatures above +15°C and below 0°C.

· If the material was stored at temperatures below 0°C, before preparing the solution, the bags with the mixture must be kept in a warm room until the temperature of the mixture is above 0°C.

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

When to insulate the house outside? - answer

When is the best time of the year to order insulation of the facade of the house?
The answer to this difficult question is not unambiguous. And there are several reasons for this:

1) The most obvious reason is the availability of funds. No matter how the performers tell you that you need to insulate now and not later, but if you don’t have money, there’s nothing to be done;

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

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

"construction" is a seasonal job

A generally noticeable trend is that people are thinking about warming closer to autumn, and this is understandable, since electricity tariffs are steadily rising. Thanks to the insulation of the house, you will reduce heat loss and, accordingly, heating costs. This is definitely a profitable investment. Insulation of the house is not only the preservation of heat, but also from moisture (condensation), and mold. Plus, foam insulation is an additional soundproofing 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 do not pursue speed and profit, our goal is satisfied customers. Our main activity is the insulation of houses from the outside with foam plastic, with high-quality sealing of the seams.

The specialists of our company are professionally trained and have high-altitude tolerances. All work is carried out to the highest quality. Your facade will be insulated with high quality at any time of the year.

To favorites!

The question "How to properly insulate?" - the undisputed weekly leader of the section "". Timbered and built several decades ago, they are already aging and begin to let the cold through in the winter months.

Mistakes when warming a wooden house

So it is very important to avoid possible mistakes, which regularly occur with unskilled wooden insulation with modern materials. Let's look at the most common of them.

Mistake #1. Log house insulation without wood inspection

As a rule, already “old” log cabins are insulated. On the one hand, it is technologically convenient: the log house has finally settled down and the dimensions of the structure remain unchanged. However, the past years could not but leave traces on biologically living material -.

Therefore, before the planned insulation, which implies that there will be no access to the logs for many years, it is necessary carefully examine all crowns and reject defective fragments. If a devouring wood is wound up in the logs, I will make a cautious assumption that it is no longer advisable to insulate the house. A cardinal cure for such a case, except for a week of forty-degree frost, has not yet been invented. Read more about this problem in the articles: Good wood should be impregnate with a fire-fighting and antiseptic composition and dry thoroughly. Performing insulation on raw wood is a mistake.

Mistake #2. Inattentive attitude to the caulk

Traditional caulking is performed, strictly speaking, not to insulate the log house, but to prevent it from blowing, which ultimately affects the preservation of heat in the house.

Deciding to insulate log facades, pay attention to the condition of the caulk on all crowns. Do not dismiss this operation. Perhaps it is due to 2-3 defects in this natural insulator that it is cold in your house in winter.

At the beginning of 2016, a reader turned to the editorial office with a request to help with modern insulation. Word for word, it turned out that cunning birds had long been pulling caulk fibers from her log house into their nests.

It seems that after this fact was clarified, our esteemed reader's craving for total warming weakened somewhat.

Without plunging into the basics of building heat engineering and without delving into the meaning of the obscure phrase "" (which underlies the choice of location), take the craft postulate on faith: insulation of buildings is carried out from the outside. Such an installation improves the operation of both the wall bearing material (wood crowns) and the insulation itself. Otherwise, both the insulation and the wood of the logs will get wet from wet vapors, which are inevitably found in the atmosphere of human habitation. Of course, we are not striving for this at all. You can read more about the features of warming the outer walls of a wooden house in the article of the same name.

Mistake #4. Rough choice of thermal insulation material

Construction markets in the literal and figurative sense are inundated with a variety of heat insulators.

However, if we introduce a strict systematization into this abundance, it turns out that everything dominates 3 types of materials suitable for log cabins. These are heaters:

from ,
from glass wool
- cellular and extruded.

Let's talk about the latter first. This is an excellent heat insulator, which has better thermal insulation qualities than the first and second ones. It practically does not absorb moisture and does not pass water vapor. It would seem that there is nothing more to dream about. However, the biggest “but” is that upon contact with an open fire, that is, when, polystyrene foam does not just burn, but only melts, but with the release of truly dangerous gaseous chemical compounds. For those readers who take these words lightly, I recommend recalling the tragedy in the Perm Lame Horse, which claimed one and a half hundred lives due to the fact that the combustion products of the insulation got into the lungs of visitors to this "tavern".

I am not opposed to the use of this material, but I vote with both hands for the thoughtful use of it. There, for example, where the fire will never reach - in the foundation, in the basement, in the blind area. He truly has no value here.

Choosing between glass wool and a mineral counterpart is more difficult. Both are perfect for warming a log house. You will learn about which thermal insulation materials are preferable from the point of view of safety from the article.

Mistake #5. Careless attitude to the transportation and storage of material

Thermal insulation materials must be dry. Only in this case they "keep" heat. And if the material gets wet, then its thermal insulation ability decreases landslide.

Remember the common "kitchen" situation: with which potholder will you grab the metal handle of a hot frying pan - dry cloth or wet / wet? I am sure that after a moment's thought, you will choose the dry option. So the insulation must always be dry. At factories during production, it is packaged in a packaging (often in shrink) film and is quite well protected from climatic moisture. But it’s worth removing the film ... Therefore:

Unpack the insulation a day before use and definitely under a canopy, and even better - in a warm house.
After fixing the insulation on the wall go directly to its lining plastering method or safety panels (etc.).
Do not leave heaters open for a long time, risking getting them wet "to the skin" with summer slanting rains.

Mistake #6. Choice of flexible mats instead of rigid slabs

In the construction market, you can find 2 options for thermal insulation materials - flexible mats and rigid plates. At first glance, these are exactly the same materials. So what to choose for facade insulation?

If you decide to opt for mats, you will be mistaken, because over the years, the insulation in a vertical position begins to sag in some places, forming cracks into which cold air rushes - the same ones that disavow all the consumer charm of modern heaters.

Rigid plates keep the sizes invariable during all term of operation. It is quite possible to walk on the slabs laid on the roof structure without losing the quality of thermal insulation.

Why, then, are flexible mats produced? - They are irreplaceable when insulating horizontal surfaces- underground space and floors. There, in principle, they cannot sag and form gaps for heat consumption.

Mistake #7. Incorrect determination of the thickness of the thermal insulation layer

To the question: “How thick should the heat-insulating layer be?” you will find a reasoned answer in a recently published article.

Here we can only confirm that when insulating a log house, two layers of material 50 mm thick will suffice placed one on top of the other. I will make a reservation that two layers are enough for the climatic conditions of central Russia. In the North, three layers of insulation will have to be placed on a wooden wall, and in the southern regions it will be possible to limit one to one.

In conclusion, I would like to give a photograph of a truly unique structure.

What is its originality? The house was built at the end of the 19th century. The house is log, but the logs, united by horizontal dowels, are installed vertically. It was insulated in the spring of 2016 with mineral wool insulation (100 mm) and lined with chipboard panels. And the entrance group is made of monolithic reinforced concrete. Truly, technologies from three different centuries have merged on a tiny spot of development.

The main task of external wall insulation is to save material resources on utility bills by preserving and concentrating more heat inside the room. Having once thought 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, such energy saving measures have long been used, which can significantly reduce heat costs.

Working with a ventilated facade

This method of building insulation is the simplest and most common today. We are talking about a reliable design with a fairly rigid frame, which must be attached to the outer wall. The construction also includes high-quality insulation, as well as facing material. In this case, it is not necessary 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 provided. 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 the construction industry will be able to produce insulation. Work can be carried out at any time of the year.

The main materials for insulation:

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

In addition to the selection of material, builders should definitely study the main features of the insulation of external walls in the winter and learn how to correctly apply them 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, the installation of a ventilated facade can be carried out at any time of the year. Winter is the hardest time to work because of the cold weather. Although with the correct organization of the 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 the winter, it should be noted that a maximum thickness of sheets of materials of 5 centimeters will be enough. Such a layer will be able to protect the premises from the negative effects of the weather even in the most severe winters.

Wall insulation is a process consisting of several most important stages. First of all, a vertical crate should be applied to the surface of the outer walls. In this case, a small wooden bar 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 laid on the surface of the crate. Dowels-umbrellas are suitable for fixing it.

On top of the insulation, it is necessary to use a special type of fabric that protects the main materials from the negative effects of moisture. At the same time, the vapor permeability of the insulation does not decrease at all, because the protective fabric is characterized by the presence of a wind and hydroprotective layer. Then comes the stage of creating the so-called diffusion gap. To do this, the crate is again superimposed. Only after completing this stage, you can safely proceed with the installation of siding. Alternatively, you can give preference to other types of topcoat.

Additional features of the work

In the process of warming, certain difficulties may arise. In many situations, thermal insulation in winter is made using, which is absolutely justified. The fact is that the material presented 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 the insulation of a wet facade is real. True, the corresponding procedure becomes more complex and costly from a financial point of view. Many companies that offer their customers a "wet" method of insulation prefer to work exclusively in the warm season. In this they differ from experienced professionals who can cope with this task even in winter. True, they can not do without the use of antifreeze additives. It is also difficult to create a warm contour around the entire construction site.

Summing up

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

In our climate, a favorable warm time for building a house is not always enough. And it seems that the construction of the house was completed by the fall, but the insulation of the walls, and less often the roof, has to be done already with the onset of cold weather.

To insulate or leave until spring is, of course, up to the owner, but if you plan to use heating or even live in a house, then the unequivocal answer is to insulate! When heating an uninsulated house, heating costs increase sharply, structures may freeze, increase humidity, low indoor temperatures and an unhealthy microclimate. Therefore, despite the difficulties of winter insulation, it is still highly desirable to complete these works as soon as possible.

The greatest difficulty in winter insulation is created by low air temperature, at which it is difficult to work on the street, especially with numerous small or fragile parts, which are very numerous when attaching wall cladding. In winter, the wall surfaces will also be cold, which is critical when carrying out “wet” work with cement mortars, such as when performing a plaster facade. In addition to cold, negative factors are precipitation in the form of snow or rain, which will prevent the drying of mortar mixtures, and can also get inside the structure.

ECOVER basalt slabs are made from stone wool with a small amount of polymer binder. At low temperatures, the properties of the insulation practically do not change: the plates do not become brittle, do not change their elasticity, unlike plastic insulation - polystyrene or polyurethane. Due to the properties of stone fiber and water-repellent impregnations, the material is practically not affected by atmospheric moisture, and in the event of wetting or freezing, stone wool slabs are easily dried due to the highly porous structure and completely restore their thermal insulation properties.

Often the developer is faced with the question of whether it is possible to leave the insulation uncovered until spring. It should be remembered that mineral wool insulation is intended for insulation in structures provided that it is protected from moisture and ultraviolet radiation. The stone base of the material is not afraid of such influences, however, the binding and modifying components, like any organic substances, will be destroyed under the influence of the sun and moisture. Of course, in winter, the intensity of solar radiation and the ingress of liquid moisture are limited, but still, the faster the insulation is covered, the higher its performance and durability will be.

Mechanical fastening of insulation and frame structures

With the “dry” method of fastening, that is, using dowels or when installing plates by surprise, there are no special requirements for winter installation, except for an amendment to frozen hands and increased fragility of the plastic parts of the dowels. It is necessary to avoid getting snow under the insulation and into the joints between the plates, and also try to close the heat-insulating layer with a cladding or windproof membrane as soon as possible. By the way, with external insulation of the main walls, no films are laid between the wall and the insulation, and vapor barrier is not applied from the inside. Outside, a hydro-windproof membrane can be used (in the assortment of many domestic film manufacturers it is marked with index A), although due to the low compressibility and low air permeability of ECOVER boards, it is allowed not to install any combustible films. When insulating frame walls, as well as in the case of wall insulation from the inside and in any ceilings and floors from the side of a warm room, it is necessary to use vapor barrier barrier films (usually marked with indexes B, C or D).

Stucco facades

The so-called "wet" processes are associated with the insulation of these facades. The gluing of the insulation boards is carried out on a cement adhesive containing water, and a reinforced preparatory and then textured decorative layer is applied on top. The plastering technology of facades implies significant financial expenses for mixtures, more durable insulation, fasteners, work, so it is better to postpone the installation for the warm season. If, nevertheless, winter work cannot be avoided, then you can act in two ways: apply antifreeze additives or make a warm contour around the building.

Antifreeze additives in cement mixtures can reduce the freezing point of water and accelerate the setting of the mixture in the cold. Such additives can be purchased separately and independently introduced when mixing mixtures. In this case, there is a risk of not keeping the proportion or getting the incompatibility of the additive with polymer modifiers of plaster mixes. Antifreeze additives can be introduced into the compositions during their production - these are special "winter" mixtures. Nevertheless, this method with antifreeze additives has the possibility of white efflorescence, cracking and obtaining less strength as a result of hardening of the mixtures. In addition, the "painless" temperature range for the use of additives is usually limited to -10°C.

A more reliable, but also costly method is the creation of a "green house", that is, the installation of scaffolding with a protective film stretched around the perimeter. Under the veil, atmospheric precipitation is not terrible, and due to heat guns, it is possible to maintain the temperature above +5 ° C around the clock.

Preservation of the plaster facade for the winter (up to 6 months) is possible according to the technical regulations at the stage of completion of the preparatory reinforcing layer, which will protect the insulation from the effects of precipitation and the sun, and after priming it will remain a reliable basis for applying decorative plaster in warm weather.

Winter insulation, of course, requires higher costs from the developer compared to summer, but these costs will still be covered by increased payments for heating the house. The most economical is to insulate the house in traditional ways with the creation of ventilated gaps. Plastering technology will require significant investments and skills, therefore, if possible, it must be transferred to the warm season.
