Roof Pitched
The high performance pitched roof system featuring PAVATEX woodfibre complies with the most stringent of standards – from baseline building regulations through to Passivhaus.
Excellent thermal performance, high protection from summertime overheating, humidity regulation, acoustic insulation and superior sustainability credentials. This low embodied carbon solution is the first choice for specifiers and homeowners alike. Woodfibre roofs are the simple, sensible system for zero carbon homes of the future.
The system features insulation both above and between the rafters and is suitable for most external finishing options, including metal, clay and slate tiling.
