The perimeter insulation, that is thermal insulation of the external basement wall, reduces heat loss in both heated and non-heated cellars. The Austrotherm XPS insulation boards provide good thermal insulation, are water-repellent and able to resist high compression strength. Therefore mounted on the outside cellar walls, they reduce the cost of finishing works. Furthermore, the pink thermal insulation boards are excellent vapour barrier. The specified heat insulation value of perimeter insulations is U (k) = 0.40 [W/m2K].
The standard low energy building requires insulation at least 100 mm thick. When it is attached to the outside wall of the basement, useful space inside can be saved and thermal bridges avoided. To the products:
