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
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

Why Tyvek® AirGuard® Smart?
• Reduced drying out time
• Durability, health and longevity of buildings
• Greater energy efficiency
• Additional drying capacity for unplanned humidity infiltration
• Enhanced interior comfort
• Trusted Tyvek® brand: robustness and durability
• Part of the Tyvek® system
Variable sd AVCL: the broader the range, the more efficient the humidity control

Choosing the right air and vapour control layer for a building project is critical to ensure full functionality of the insulation and its optimum performance, thus resulting in greater energy efficiency and more comfortable internal climate.
DuPont™ Tyvek® solutions can significantly improve home energy efficiency. The combination of low-emissivity, vapour-open Tyvek® Reflex and AirGuard® Reflective is particularly effective.
