A high-quality semi-self-adhesive underlay for gently pitched roofs with a minimum slope of 2°. Due to its semi-self-adhesive nature, there is no need to apply the underlay with a roofing torch. Just stick it on. When heat welding the top layer, the heat is sufficient to heat weld the underlay as well. The underlay has a peel-off film, making installation quick and easy. This underlay is made from high-quality elastomers and bitumen and has a polyester-glass combination insert. The pressure-distributing stripe pattern makes blistering impossible. The top of the underlay is finished with a burn-off film. When heat welding the top layer, the film spreads out and acts as an adhesive.
- Quick and easy to apply
- Pressure-distributing stripe pattern
- Prevents blistering
