Vapour check membrane for external insulation

connect variant 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

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).
