Airtightness systems

Vapour check and airtight membranes with humidity-variable diffusion resistance provide the best protection against moisture and mould-infested components. In combination with moisture-active wind-sealing membranes on the exterior, they significantly improve the protection of building components and facilitate a healthier, mould-free indoor environment.
