Product description

Inexpensive vapour check membrane

171 Alfa Rufol varia E is a simple, light vapour barrier for the creation of an airtight building shell. The red auxiliary lines help you create exact overlaps. The membrane allows moisture to escape - if necessary (in summer) even back to the inside of the building (re-drying). This process keeps the insulation dry and prevents damages to the building.
Suitable for insulations between rafters (internal or external) as well as over rafter insulations. Alfa varia E is a lighter version (lower grammage) of 171 Alfa Rufol varia with all its essential characteristics.
