In areas with a very harsh winter in a two-layer wall, it may be advantageous to lay the bearing part of less durable, but more “warm” blocks: aerated concrete, gas silicate, foam concrete or porous ceramics, with a density of 600 – 1200 kg / m 3. This solution will reduce the thickness of the layer of highly efficient insulation, but due to the lower strength of the wall material will have to increase the thickness of the walls.
One square meter of the frame wall contains the maximum amount of highly effective insulation. This is probably the most profitable construction of walls in terms of the recoupment of construction costs.
The frame wall of an inexpensive home for a harsh climate:
- Between the racks of the frame slab mineral wool insulation density of at least 45 kg / m 3. 100-200 mm thick.
- Outside of a plate of insulation from extruded polystyrene foam (EPS) or foam or facade slabs of mineral wool with a density of at least 125 kg / m 3. 40 to 100 mm thick.
- Thin-layer plaster on the insulation.
