Sandwitch roof insulation
This type of roof can be with a frame and frameless base. The base was farac, then the insulation should have ease, for example, like a basalt slabs, mineral wool slabs, URSA and isover. Their density is 70 kg/m3. If the base is still frameless, then the insulation should be dense. In this case, the basalt slabs and mineral wool slabs are suitable, in which the density reaches 100 kg/m3. The insulation in the composition of an extruded polystyrene foam is also suitable.
