Flame-resistant breather membrane (WRB) for open-jointed cladding, gap width up to 35 mm (1 3/8”), with self-adhesive strips

Variant without self-adhesive strips

Advantages

  • Improved safety: 'not easily flammable', fire classification B-s1, d0 as per EN 13501-1
  • Well-protected building structures: highly permeable and, at the same time, maximum protection against driving rain
  • Not visible behind open-jointed cladding: black fleece with printed marking only in the overlap area
  • Highest possible durability and thermostability thanks to the monolithic functional film
  • 6 months of outdoor exposure
  • Quick and reliable sealing thanks to the integrated ‘connect’ self-adhesive strips on the long strips of the membrane

Areas of application

For use as a breather membrane (weather-resistive barrier, WRB) behind closed and open facades (open-jointed cladding up to a gap width of 35 mm (1 3/8”); cladding width = at least 3 x gap width). Installation onto boarding, wood-based panels and all mat or panel-shaped thermal insulation materials.
