Product Description

Protect A1 can be used for all pitched roof constructions (tiled and slated), whether the insulation is at ceiling joist level or at rafter level. It is a twin-ply construction of polypropylene non-woven spunbond layer and PP film.

Protect A1 is a ‘third-generation’ roofing underlay which has been developed specifically to overcome the disadvantages of traditional Type 1F felts and second generation plastic sheet materials.

Please note this product does not require the joints & laps to be taped but must be battened correctly.

Good value and hopefully will do the job but may have to wait years before we know. Very slippery to walk on pitched roof.
