ALUVEX
ALUVEX is a highly tear-resistant, reflective and reinforced vapour barrier with a high sd value for roof applications. It is designed for installation on the interior side of thermal insulation in roof constructions, helping to protect the insulation against moisture ingress from inside the building and reducing the risk of condensation. The reflective surface supports the reflection of radiant heat back into the interior, while the reinforced structure improves the membrane's strength and tear resistance.
- High sd value of 130 m – helps protect thermal insulation against moisture ingress
- Reflective surface – supports the reflection of radiant heat
- Reinforced structure – increases strength and tear resistance
- Airtight – supports the creation of an airtight layer within the roof build-up
