Protect A1 ‘Third-Generation’ Roofing Underlay

Protect’s leading ‘third-generation’ roofing underlay has been developed specifically to overcome the disadvantages of the traditional Bitumen based Type 1F felts and second generation smooth plastic sheet materials.

Protect A1 can be used for all pitched roof constructions (tiled and slated), whether the insulation is at ceiling joist or at rafter level. It is a twin-ply construction of polypropylene non-woven spunbond layer and PP film giving it an excellent nail tear and tensile strength properties. It has an absorbent undersurface which prevents condensation drip-off.

The membrane is completely waterproof, UV and heat stable and can be used as a temporary covering for up to three months before the permanent roof covering is laid. It’s easy to cut, clean and is light to handle and does not generate noise under wind gusting. The embossed dark grey upper surface reduces glare and takes a chalk line marking and is unaffected by temperature changes.

Protect A1 is BM TRADA Independently certified for all applications having a wind uplift performance of 2.5kPA at 343mm batten spacing enabling unrestricted use in all exposure conditions in the UK and Ireland.
