  • Easy to lay
    The surface structure is especially slip and wear-resistant, making DELTA®-PVG (PLUS) very easy to lay and ideal for laying beneath over-rafter insulation.
  • Vapour diffusion inhibiting
    The diffusion inhibiting material combination with the low Sd value of approx. 20 m means DELTA®-PVG (PLUS) makes a key contribution to dry and healthy roof constructions. The membrane is in accordance with DIN EN 13984: 2013 vapour control layers.
  • Universal application
    DELTA®-PVG (PLUS) can be used as both an air and vapour barrier and as roofing membrane. In both applications it can be used as temporary roofing with the DELTA® system accessories.


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.
