How to insulate the brusade house

Question: Warming of a brusade house. The construction company made a project at home 6x8 m with an attic (frame), and the same company built a house, 1st floor, a thickness of 150 mm thick. What thickness should be the insulation (minvat) and what is better to be wintering?

Possible option: Foil foil foil to the wall, then 2 layers of 50 mM minerals and again foofol foil outward, counterbask, siding? Although some builders argue that the counterpart is not required.

Answer:It follows from this that the house is already cooked, covered in roof. The latter means with the insulation of the attic of the attic, you have already been late, - at least without removing the roof it will do it difficult. Therefore, we will dwell on the insulation of the walls, and necessarily outdoor. The real coefficient of heat transfer resistance (the main consumer indicator of thermal insulation) of the existing wall fence with you is about 0.8-1 W / mx ° C. Although according to modern requirements for PMG, it should be about 3.5 about 3.5. But this concerns only houses built on the urban order. It is really necessary to have a wall with a thermal resistance of about 3 VG / MX ° C. So, 2 units of thermal insulation must be reached due to the insulation.

This is about 15 cm thickness of mineral wool slabs. It is plates, since mats from the same material with time can coach and organize completely unnecessary cold bridges. Internal vapor barrier from the beautiful foam material is removed: it creates a greenhouse effect for your bar, as a result of which the latter can start rotting.

The wetting of Minvati because of the location of the dew point in its thicker during the siding outdoor trim, there is no reason. The counterproof does not prevent, as it creates an additional ventilation gap, which will leave moisture from the insulation. The scheme of laying insulation and foams of laying is reasonably used with the mandatory insulation of the floor and the ceiling.
