  • Bonding with the future-oriented strip system
    DELTA®-NEO VENT PLUS offers a reliable moisture protection through an innovative strip system in the upper adhesive area. Each individual strip creates a barrier against running water or possibly ascending humidity in the overlap area and thus can create additional security. It is not necessary to cover the adhesive areas down to the centimetre.
  • Vapor-permeable
    Thanks to a combination of vapor-permeable materials that create a low Sd value of approx. 0.02 m, the membrane ensures dry and healthy roof structures.
  • Easy to apply
    The membrane is easy to apply thanks to its low weight of 135g/m². The surface structure is very slip resistant and therefore very easy to apply.


DELTA®-NEO VENT PLUS is a robust universal membrane that can be used to protect roofs with covering and as a roofing membrane (separating layer) under metal coverings, slate, fibre cement roof panels or shingles.

It can also be used as a façade membrane behind façade cladding with closed joints.
