Product Information
Novia® Black+ Supreme Roof and Wall Breather Membrane is a high quality, strong and versatile breather membrane for all pitched cold and warm roofs, as well as insulated wall applications. The material meets EN 13859-1 for pitched roofing and EN 13859-2 for walls.
Novia® Black+ Supreme has excellent water resistance but still provides high breathability. It also complies with EN 13501-1 Fire Classification Class E. The product is completely black on one side, grey on the reverse, with no text or images, except for a 150mm overlap line.
