Gerband sd VARIO Membrane is a multi-layered vapour barrier with a moisture-variable sd value. It’s used indoors to create an airtight barrier and a vapour control layer for the protection of the construction according to DIN 4108.
Gerband sd VARIO Membrane is a reliable airtight and vapour control layer. During the winter it reliably prevents diffusion of interior humidity into the roof and wall construction. As a result – during summer it allows for back fusion from the insulation as well as the wall and roof construction. It also prevents condensation that facilitates mildew growth and constructional damages.
