Our high performance breather membranes, for use in construction and roofing, are fully certified and guaranteed to offer the best protection against condensation. Permavent breather membranes were fully certified for use in all roofing applications.
Permavent breather membrane is good at controlling condensation that it is the only 3 layer roofing membrane to pass the air permeability test from the Building Research Establishment (BRE) and will offer the best option for use as a better alternative breather membrane to our rival brand leaders such as Tyvek, Klober and Roofshield (when used as roofing felt).

Easy Roof Systems - Low Pitch Slating
We have used our roofing and production expertise to develop the `Easy Roof Systems' which will considerably enhance the performance of a slated roof. The Easy Roof System allows any slate roof to be installed at a low pitch, as well as increasing the air permeability, eliminating wind slate rattle and improving the look of any slate roof.
"The Permavent Easy Slate system significantly improves the resistance of both natural and fibre cement slates to wind driven rain."
