Diffusion-open, weldable roofing underlay membrane


  • Homogeneously weldable
  • Non-slip and abrasion-resistant surface
  • Diffusion-open and, at the same time, rainproof against driving rain
  • Extremely high tear-resistance
  • As a roofing underlay with the most stringent safety requirements
  • Monolithic membrane

Areas of application

As a 3-ply diffusion-open, homogeneously weldable, rainproof/watertight roofing underlay. Suitable for installation on pressure-resistant subsurfaces, e.g. wooden decking, wood-based panels and wood-fibre underlay panels.
