DELTA®-PVG PLUS: Vapour Control Layer for Over-Rafter Insulation
DELTA®-PVG PLUS is a vapour-permeable roofing underlay for pitched roofs. Laid over rafters or sarking boards, it protects the roof and insulation from wind-driven rain, snow and dust, while letting moisture from inside the building escape.
Supplied in Ireland by Commons House Design, the official Dörken DELTA® partner in Ireland, with a showroom in Athy, Co Kildare.

Advantages
- Easy to lay
The slip- and wear-resistant surface makes installation simple, especially beneath over-rafter insulation.
- Vapour diffusion inhibiting
Its material combination and Sd value support dry, healthy roof constructions and conform to DIN EN 13984:2013 vapour control layers.
- Universal application
Works as both an air and vapour barrier and a roofing membrane, and can provide temporary roofing when used with DELTA® system accessories.
Where to Use
Primarily used as an air and vapour barrier beneath over-rafter insulation. Its vapour control value and non-slip surface make it suitable for all common types of over-rafter insulation. In ventilated roofs, it can also act as a base layer under slate, fibre cement or shingles.
