Protect A1

Protect A1 is a ‘third-generation’ roofing underlay.  It is developed specifically to overcome the disadvantages of traditional Type 1F felts and second generation plastic sheet materials.  Therefore you can use Protect A1 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 spun-bond layer and PP film.
