Recently, the relevance of facade heat insulationapartment buildings are increasing. This is due to the increase in prices for utility tariffs and energy, which explains the need to save money. The problem is that the majority of apartment buildings that are currently in use were built almost 50 years ago, their insulation is not as effective as the owners would like.
As statistics show, heat loss throughthe wall comes to 50% of the total heat loss. This is very significant. This indicator depends on the design features of the house. So, if we are talking about panel buildings, the heat loss is maximum, and in the case of brick houses, this figure is somewhat less.
But the insulation of facades of apartment buildingsprofitable from any angle. If property owners use autonomous heating, they will be able to save approximately 20% of the amount spent previously on gas consumption. If the apartment is connected to central heating, the average indoor temperature will increase by an average of 4 ° C.
Warming of facades of apartment buildings is usually carried out using one of the following materials:
Each type of insulation hasits pros and cons, which determines the relevance of the use of a particular material in a particular situation. If you want to save, you should use foam. It has a low price, which is why it is most common. It can be used anywhere, the effectiveness of thermal insulation will be enough. However, the pursuit of cheapness is not always justified. If the walls initially have a normal class of insulation, the insulation foam will allow you to achieve the desired result. When choosing this material should take into account its density. The higher it is, the less its heat-conducting properties.
Warming facades of apartment buildings is prettyoften carried out using expanded polystyrene. It is quite inexpensive, and its heat-insulating properties are better, compared to foam plastic. Among the advantages can be identified low weight, ease of installation, hydrophobicity and long service life. Styrofoam is excellent for facing corner apartments. The material almost does not absorb moisture.
If you are planning to carry out facade insulationapartment buildings using polystyrene foam, it should also take into account its shortcomings. They are expressed in low resistance to fire and the absence of sound-insulating abilities. The first quality requires the installation of fire bridges. However, styrofoam is great for thermal insulation of walls inside and outside the house.
This material is one of the mosteffective, but its cost exceeds the price of analogues. For this reason, this material is used quite rarely for thermal insulation of facades. Among its advantages it is necessary to single out fire safety, excellent sound insulation properties and hydrophobicity.
It should be noted, and one drawback that is a lot of weight, as a result of which its installation on the facade is carried out with a large number of fasteners (dowels are used as the latter).
When a thermal insulation material is selected forinsulation of the facade of an apartment building, quite often foam glass is also considered. It is quite expensive, but if you are not limited in means, then preference should be given to him, because this insulation has excellent thermal insulation properties, hydrophobicity and durability.
Foam glass is not combustible material on itssurfaces can not form mold and fungus, as well as other microorganisms. If you use this insulation material, you will need to purchase a large number of related products:
For fixing used dowels, you will needfor work also liquid foam. To level the surface you need to stock up on plaster. For additional waterproofing, a primer is applied to the walls, which improves the adhesion quality of the plaster with paint. For fixing the plaster layer is needed mesh for reinforcement.
Warming of old houses can be done byone of several technologies. Quite often for this are used polystyrene plates. At the first stage, the facade is prepared, dry mixes and necessary materials are purchased. In the next you can proceed to the gluing of heat-insulating sheets on the walls.
Дополнительно скрепить полотна можно пластиковыми dowels The surface of polystyrene foam is reinforced with a polymer mesh, after which you can begin to apply one or two layers of plaster. Polystyrene plates, the price of which is quite acceptable, can achieve good results. Such pasting of facades is carried out at the stage of construction of buildings.
The above technology providesthe need for wet work. An alternative solution is another method, which is to install siding with thermal insulation. First, a frame is erected using a steel profile. For this apply dowel-nails, screws and suspensions.
Следующим шагом станет установка минеральной ваты on the wall, it will be especially convenient to use plates of basalt fiber. Such a system of insulation provides for the installation of a steam and water barrier, as it usually acts as a windproof membrane that reduces the blowing out of heat from the house. At the final stage is installed siding.
This technology has several advantages.Among them it is necessary to highlight the absence of the need for the master to have special skills for plastering and painting works. In addition, if you use high-quality PVC-siding, then when properly installed, it will be ready to serve at least half a century.
Довольно часто в последнее время используется patchwork insulation of facades of apartment buildings. It involves the point of thermal insulation. If you apply siding and mineral wool, then finishing does not require additional care during the entire period of operation.
При наступлении теплого сезона достаточно будет just wash the surface of the walls, which then re-gain an attractive appearance. For insulation can also be used polystyrene plates, the price of which is 1130 rubles. per pack.
