DuPont™ Tyvek® AirGuard® Smart
Protection against structural damage with variable vapour resistance
Tyvek® AirGuard® Smart prevents structure damage and loss of insulation efficiency by smartly adapting to various moisture conditions and regulating the humidity in building elements.
DuPont™ Tyvek® AirGuard® Smart adapts:
• to allow faster evacuation of built-in humidity in new constructions elements (e.g. wet rafters)
• to avoid humidity infiltration from the living space into the construction elements during winter
• to allow moisture trapped in the structure to escape into the inside
