FORTIS 190 Breathable Roof Membrane – 75m² Roll (Red)

FORTIS 190 Breathable Roof Membrane is a three-layer, highly vapour-permeable roofing membrane designed for pitched, insulated and ventilated roofs.

With excellent tear resistance and a membrane weight of approximately 190 g/m², FORTIS is suitable for professional roofing applications, new-build construction and roof renovation projects. It can be used under concrete tiles, ceramic tiles, metal roofing tiles, aluminium sheets and natural slate.

The membrane can be installed directly in contact with thermal insulation such as mineral wool or glass wool, without requiring a ventilation gap between the membrane and insulation. It is also suitable for roofs with full boarding. The finished roof covering should be installed using battens and counter-battens.
