DuPont™ AirGuard® Reflective
Verified by manufacturer 1 month ago
Internal airtight vapour control layer (AVCL) offering high vapour resistance and low emissivity.
Application
Suitable for use in SFS, timber, CLT and masonry wall systems, pitched and flat roofs. Suitable for installation behind internal linings of wall or roof assemblies or on cement particle board behind insulation in rain screen-cladding systems.
Description
A 100% airtight vapour control layer (AVCL) with very high
vapour resistance and low emissivity reflective surface.
Features and benefits:
- Chlorine resistant.
- Significantly boosts thermal performance when used with a services void/ batten space.
- Highly vapour resistant.
- Airtight and water resistant.
- CE-conformity for plastic and rubber vapour control layer (EN 13984).
- Reflects ca. 95% of radiant heat.
- Reduces heat loss by increasing R-value of the airspace to 0.75 m²k/w.
- Good mechanical strength.
- Reaction to fire: Class E.
- Considerably reduces risk of condensation.
