Arrangement of thermal insulation on heavy structures
If there is a need to ensure thermal insulation, but the weight of the structure is large, mineral wool is used, which has good heat -insulating properties.
To prevent the cold bridges, you do not need to save on mineral wool. The more multi -layer the roofing isolation is obtained, the more maximum protection from the cold will be. Along with Minvata, the already mentioned windproof membranes and vapor barriers should be used. By the way, instead of foamed polyethylene, foam polyethylene can be used. It is attached in the same way – on the base of the structure. To ensure a more effective withdrawal of water vapor, the gap between foam polyethylene and finishing material should be provided. There will be enough gap of about 15-20 cm.
