Pro Breather Membrane 1 x 50 m
BBA-approved breathable membrane with integrated tape. 122 GSM.
Suitable for:
High performance roofing membrane that is vapour permeable, water resistant and airtight. They allow vapour to escape from the inside whilst repelling rainwater from the outside, helping to minimise condensation in the roof space.
The membranes are available with or without integrated overlap tap.
Weight: 122 GSM

Wind Zone Suitability
The wind uplift resistance figures for Easy-Trim breather membrane applies in the geographical wind zones stated on the datasheet, where a well-sealed ceiling is present and the roof has a ridge height of ≤15m, a pitch between 15° and 75°, and a site altitude of ≤100m, and where the topography is not significant.
The required uplift resistance for other roofing projects should be determined using BS 5534: 2014 +A1: 2015 and the declared wind up lift resistance which can be made available through our technical department.
