Diffusion-open, weldable roofing underlay membrane strips

Advantages

  • Reliable seam sealing: homogeneously weldable as part of the SOLITEX WELDANO 3000 system
  • Can be used flexibly: also suitable for large counter battens
  • Easy to work with: robust with extremely high tear-resistance
  • Maximum protection: diffusion-open, rainproof against driving rain, and highest hail-resistance HR 5 (Swiss VKF/AEAI directive) and as per EN 13583
  • Can be easily cut to shape using a knife or scissors

Areas of application

For reliable sealing around counter battens as part of the SOLITEX WELDANO 3000 system.
