A lightweight breathable roof underlay for cold and warm roof applications which give major benefits over traditional roof underlays.
A triple layer fabric, high performance breather membrane, made fromhigh tensile spun bonded polypropylene layers, around a micro‐porous polypropylenefilm. Designed for use in a fully supported or unsupported tiled, slated or metal roofsystem.
The high vapour permeability and waterproof nature of the membrane, combined withexcellent tensile/tear strength and high wind uplift resistance make it theprofessional’s choice as the ultimate breather membrane.
It is equally suitable whetherdraped unsupported over rafters or laid directly over insulation. The outer layer forms the functional waterproof surface, the middle layer is thebreathable waterproof membrane, and the inner layer protects the membrane from abrasion and damage, also giving additional strength. This enables the fabric to allowmoisture vapour to pass through, whilst remaining fully waterproof.
