Warming of attic

The attic is a subterranean non-residential space, which is usually not heated, on the one hand it is limited by a roof, and on the other - by ceilings. There is usually an isolation to cut off the main housing from the street. Since the roof contributes a large part of the heat loss, the insulation of the attic is a very important task, which should be taken as seriously as possible. Qualitatively performed work allows to significantly reduce these losses, as well as expenses for heating the dwelling, contributes to the formation of a normal microclimate inside the building.

Warming of the attic is most often carried out in two ways - the material can be fixed to the roof slopes with insignificant insulation of the attic floor, and only the ceiling can be protected. The difference will be in both technology and air temperature in the attic in winter. The roof slopes are insulated using plate or roll mineral mineral materials. If you insulate the attic floor, then you can use expanded polystyrene, mineral wool, granulated heat insulators. While they are cheap enough, they all require the use of additional hydro- and vapor-insulating layers. These layers are membranes and films fixed with special care throughout the surface, which needs insulation, and their main function is not to let the water get into the layer of the basic protective material.

If the attic insulation is poor quality or incorrect, then the material used can begin to accumulate moisture, which significantly reduces its properties for thermal insulation, leads to a fairly rapid destruction.

Plate and roll materials, which are commonly used, have another drawback, there are seams that can pass a lot of heat. Seams appear in the places where the plates adjoin the structural elements, and where they join. Warming of the attic in this way even with a very high quality of laying leads to the fact that the overall efficiency decreases by 15-25%. This is why all joints and junctions must be treated with a mounting foam.

It is worth remembering about such a feature of mineral wool and granulated heaters, like rapid shrinkage in the first years of operation, which can be 15%. It is important to add another 15% to the required index, which will compensate for this shrinkage. Similarly, it is worth choosing a heater for the ceiling.

It turns out that the apparent simplicity and cheapness of mounting traditional materials that are used for insulation, is nothing more than a myth.

If you observe the technology of their laying, as well as the requirements prescribed in the building codes for calculating the required thickness, it is possible to significantly increase the price of the material itself, as well as provide additional work that involves the installation of special layers of insulation, as well as quality installation. The same can be said about the facade insulation systems.
