Glidevale Protect A1 T3 is a high performance impermeable heavy-duty type HR roofing underlay, developed to overcome the disadvantages of traditional Type 1F and 5U felts and second generation plastic sheet materials. It has an ultra tough 4 ply construction with heavy-duty non-slip reinforcing grid on the upper surface for maximum damage resistance.

Glidevale Protect A1 T3 provides a secondary line of defence against wind driven rain and snow and resistance to wind uplift. Being entirely waterproof it can be used as a temporary roof covering during the period the roof covering is applied.
