High-quality air and vapour barrier for use beneath on-roof insulation.
Can also be used as three-layer roofing membrane for ventilated roofs.
The membrane can be used in ventilated roof constructions as base layer, for example below slate, fibre cement roofing or shingles.
DELTA®-PVG (PLUS) can be used as an air and vapour barrier beneath over-rafter insulation in particular. The combination of the Sd value of approx. 20 m and the non-slip surface structure makes the membrane especially suitable for laying beneath all kinds of over-rafter insulation.
