    DELTA®-VENT X PLUS in der Anwendung


  • Highly tear-resistant
    Thanks to its four layers, DELTA®-VENT X PLUS offers a higher-than-average tear strength of approx. 520/520N/5cm lengthwise and also in a transverse direction. The membrane creates the highest level of security during processing - even on roofs with large batten widths according to DIN 4426.
  • Bonding with future-oriented strip system
    DELTA®-VENT X PLUS enables a reliable moisture protection through the 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 so can create additional security. It is not necessary to cover the adhesive areas down to the centimetre.
  • Product may also be used as temporary cover
    DELTA®-VENT X PLUS meets all the requirements of the ZVDH regulations and can be used as a temporary cover in combination with the system accessories of DELTA®.


DELTA®-VENT X (PLUS) is a robust universal membrane that can be used as a roofing membrane to protect roofs with covering and as a separation 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.

The membrane also increases work safety on roofs with large battens according to DIN 4426.
