AirGuard® Sd23
AirGuard® Sd23 is a vapour controlling and waterproof membrane composed of DuPont Typar® spunbond coated with Polyproplylene. AirGuard® Sd23 is used to prevent moist air from penetrating the insulation layers of the wall and roof construction from the inside. This prevents condensation and ultimately mold from forming in the insulation. The membrane has exceptionally high tear resistance and is easy to process.
