Air Tightness Membranes

Gerband SD Variable Control Airtight Membrane 10.5m x 40m enables airtightness and vapour control in roof and wall constructions. During the winter it reliably prevents diffusion of interior humidity into the roof and wall construction whereas during summer it allows for back fusion from the insulation as well as the wall and roof construction.

The Vario KM Duplex UV is an intelligent, reinforced, laminated water vapour retardant climate membrane with a moisture-variable sd of 0.3 m to 5 m. Supplied in a 40m x 1.5m roll.
