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
