Permeable, homogeneously weldable roof lining membrane

 

Advantages

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

Application

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