Cellar walls 

and foundation walls

Due to their high compressive strength, termPIR boards successfully play the role of thermal insulation of underground storey walls. In addition, by using a glass veil lining boards impregnated with bituminous binder (termPIR® BWS), you can glue the waterproofing layer to the thermal insulation using bituminous glue.
