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.

Mould damage because of trapped moisture (left) -  healthy construction (right)
 

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

TYPICAL APPLICATIONS BENEFITS
New construction

Reduced drying out time.

Drying out by moisture migrating back into the building

Renovations from the exterior Allows continuous installation of AVCL from the outside without risking condensation to the upper side of rafters
Flat and pitched roofs with HR (High Resistance) underlay

Only an adaptive AVCL allows drying out in this type of

application

Use a standard AVCL *    

Why Tyvek® AirGuard® Smart?

  • Reduced drying out time
  • Durability, health and longevity of buildings
