Novia Black+ 112GSM Roof and Wall Breather
Our lightweight 112gsm breather membrane, with excellent water resistance which meets EN 1928 W1 Class.
Novia® Black+ Roof and Wall Breather Membrane is a high quality, versatile, low cost, 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 EN113859-2 for walls. Novia® Black+ has excellent water resistance but still provides high breathability; it is strong yet lightweight and also complies with EN113501-1 fire classification grade E. The product is completely black on one side, grey on the reverse, with no text or images on, except for a 150mm overlap line.
Novia® Black+ meets the requirements for UKCA marking, originally introduced under the 2013 Construction Products Regulations with CE marking. Under this European directive, all products covered by a current hEN (harmonised European Norm) must comply with the new standard. Third party accreditation is no longer sufficient. This has been adapted to UKCA following the UK departure from the EU.
Novia® Black+ is suitable for use in BS 5534 wind uplift applications. Following successful tests, Novia® Black+ can be used in zones 1 without additional tapes (≤345mm battens), and in zones 1-5 using our Breather Membrane Lap Tape.
For a material with higher fire rating, please see Novia FR Breather Membrane which is Class B-s1,d0 fire rated.
