Vapour check membrane for external insulation and roof refurbishment, with self-adhesive strips

Variant without self-adhesive zones


  • Protects building structures against weathering during the construction phase for roof pitches of 10° (2.1:12) and higher
  • Water-resistant and waterproof, can be walked on
  • Acts as a vapour check and airtight layer simultaneously
  • Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
  • Quick and reliable adhesion thanks to the integrated ‘connect’ self-adhesive strips on the long edges of the membrane

Areas of application

For use as a vapour check and airtightness membrane directly on top of sheathing underneath suitable external roof insulation made of all insulation materials on structures that are open to diffusion on the exterior (roofing underlay with SOLITEX MENTO 3000, for example).

In addition, DA connect can be used as an airtightness membrane and refurbishment vapour check between two layers of insulation. All fibrous insulation materials can be used for insulation installed between rafters; the external roof insulation must be a foam insulation material (e.g. consisting of PUR, PIR or EPS). Please contact Technical Support at pro clima in Germany for assistance with calculating the thickness of the external foam insulation that is required from a building physics viewpoint. If necessary, the outer sealing layer should be implemented using a diffusion-open roofing underlay membrane (e.g. SOLITEX MENTO 3000).
