Breathable under roof fabric
Highly breathable, watertight roof underlay with wind barrier.
Breathable, lightweight, non-slip and highly tear-resistant synthetic membrane, composed of three thermally sealed layers.
Top layer: non-woven polypropylene (PP) fabric, non-slip, water-repellent and UV-stabilised.
Middle layer: microporous membrane allowing vapour diffusion, watertight.
Bottom layer: non-woven polypropylene (PP) fabric.
- No heat dispersion;
- Energy saving.
Thermal insulation protected from accidental infiltration of water and atmospheric agents, which could compromise functionality.
- Highly permeable to water vapour;
- Expels excess moisture coming from inside the house;
- No condensation formation in the thermal insulation if used in conjunction with a vapour retarder on the hot side (inside).
- Double-sided adhesive tape built into the overlap area for optimal hermetic sealing;
Avoids the use of additional adhesive tapes to seal the joints.
Does not act as the final roof cover.
Carefully follow laying instructions.
For Wütop 150, watertightness and wind resistance are only guaranteed if the joints are sealed with specific Eurasol® tapes or Wütop WRD adhesive.
For direct laying on the cold side of the thermal insulation on pitched and ventilated roofs.
For the waterproofing and wind protection of walls.
