Tyvek AirGuard Smart Air and Vapour Control Layer by DuPont – 1.5m x 50m


Tyvek® AirGuard® Smart is an innovative air and vapour control layer which protects structures against environmental damage by adapting to various moisture conditions and regulating the humidity in building elements.
The design of Tyvek® AirGuard® allows for faster evacuation of built-in humidity in new construction elements. It also means avoiding humidity infiltration from living spaces into the building’s structure, minimising the risk of expensive damage from damp and mould.
