How to warm the walls from the inside, what materials are used
This method of thermal insulation is used to create three -layer walls. In this case, the main supporting wall is connected by steel anchors with the enclosing outer layer (brick, tiles, stone and. T.D.) so that they can hold the enclosing wall from the exposure of the external environment (wind, moisture, temperature difference).
If polystyrene foam is used as a heater, then there is no need to leave a gap between the insulation and facing. If mineral wool is used as a heater, then between them it is necessary to leave a 3 -centimeter ventilated gap.
In buildings with the old structure, the gap was used as “heat -insulating voidness”, if emptiness is sufficient, then you can insulate the building with injection or blowing, but if the gap is not so large, then the insulation will not bring the desired results and you will have to look for other methods of insulation (outside or outside or outside or outside inside).
