Gerband Air Tightness SD2 Control Membrane | 1.5m x 50m

Gerband Air Tightness SD2 Control Membrane is a reliable vapour control layer that enables airtightness and vapour control in roof and wall constructions. During winter, it reliably prevents diffusion of interior humidity into the roof and wall construction. During summer, it allows for back fusion from the insulation as well as the wall and roof construction preventing condensation that facilitates mildew growth and constructional damage.
