Part of The Specialist membrane range, Extreme is the UK's leading low pitched roof underlay. This makes it the perfect solution for complex roofs, whilst it is also fitted with self-adhesive tape.
Part of The Specialist membrane range, Permo Extreme is a tear-resistant roof underlay designed for use on low pitched roofs, down to a minimum roof pitch of 12.5° for interlocking tiles, 15° for slates and 22.5° for plain tiles. This makes Permo Extreme roof membrane the perfect solution for extensions and lean-tos, particularly as the roll is available in a half-size for smaller projects. The membrane is fleece lined to control condensation, whilst it’s fitted with self-adhesive tape, which provides a permanent seal of overlaps and immediate weatherproofing protection against wind, rain and snow. Permo Extreme is also highly temperature resistant from -40°C to +100°C and can be deemed as a primary barrier when installed with Klober accessories and covered by a UV protected layer such as tiles or slates.
When the right membrane solution is specified and installed correctly, a low pitch roof can be constructed without concern for future performance.
