Novia Black 115GSM Roof and Wall Breather
Our most popular standard grade roof and wall breather membrane
Novia Black Breather is a low weight, high performance breather membrane suitable for use as a breathable roof underlay. It has excellent water resistance and is suitable for direct installation over insulation, boarded roofs or rafters. The product is suitable for all pitched cold and warm roofs, and may also be used as a high specification wall breather. The roll is black on one side, with lines for lapping over, and white on the reverse.
Novia Black has been introduced to comply with new mandatory CE marking requirements, introduced under the 2013 Construction Products Regulations. Under this new 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. Any affected products manufactured after the implementation date in July 2013 must conform to the new CPR standard.
Novia Black is suitable for use in BS 5534 wind uplift applications. Following successful tests, Novia Black can be used in zone 1 without additional tapes, and in zones 1-5 using our Breather Membrane lap tape.
