DA connect
Vapour check membrane for external insulation, with self-adhesive zones
Advantages
- 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 zones on the long edges of the membrane
Areas of application
For use as a vapour check and airtight membrane on roof decking 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).
