In our difficult time, payment for energy supply is quite high. One of the methods of savings is the insulation of the house. This method is also effective if your house is connected to a common heat center, and you directly depend on the time and quality of heat supply.
The easiest and most common way of insulation is wall insulation. The insulation of the outer walls is usually performed by slabs of polystyrene foam or mineral wool. For external work, it is worth using polystyrene foam with a density of at least 15 kg/m3, you can use with greater density, for example, 20, but it is more expensive in cost, mineral wool slabs use hard or semi -burning with a density of 80 to 150 kg/m3. There are also lamellas, these are mineral wool slabs with fibers located perpendicular to the plane of the plate.
On average, the thickness of the thermal insulation of the facade should be about 8-15 centimeters, thinner isolation is used to warm door and window openings.
It should be borne in mind that there are differences between the insulation of the old house and the newly under construction. Therefore, for starters, you should get acquainted with various technologies for insulation of the outer walls, which will help to choose the right materials and prepare for work.
