Diffusion-open, weldable roofing underlay membrane strips

Advantages

  • Reliable seam tightness: 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
  • Protects structural elements against dampness: diffusion-open, rainproof against driving rain, and hail-resistant
  • Can be easily adapted using a knife or scissors

Areas of application

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