SOLITEX WELDANO
Diffusion-open, weldable roofing underlay membrane
Advantages
- Reliable seam tightness: homogeneously weldable
- High degree of occupational safety: non-slip and abrasion-resistant surface
- Protects structural elements against dampness: diffusion-open and rainproof against driving rain
- Easy to work with: robust with extremely high tear-resistance
- Suitable as a roofing underlay to meet the most stringent requirements
- Also keeps structural elements dry during the construction phase: excellent protection against driving rain thanks to 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. timber sheathing, wood-based panels and wood-fibre underlay panels.
