KRUMBER CONTROL 100 2-layer membrane with a unique non-woven fabric structure based on polypropylene-based hot cast foil. This solution offers product which retains moisture on its surface, preventing moisture condensation from membrane run-off. The retained moisture has longer to evaporate. This ensures maximum partition tightness of all types of roof structures, attic and inside walls. Protects thermal insulation and roof structure against moisture entering from the inside of the building. When it comes to walls structure, it prevents plasterboards from damp and mould.
