VARIO® XTRA

The membrane Vario® Xtra consists of a polyamide-based film paired with a polypropylene non-woven fabric which provides a broader range of water vapor diffusion resistance. 

Vario® Xtra is used in building, for instance loft, sarking, attic floor, massive walls with internal insulation and timber frame wall. With a Sd-value from 0.3 m to 25 m, Vario® Xtra significantly limits the water transfer from the building interior to the construction, while allowing damp materials to dry out effectively depending on the relative humidity.
