Glidevale Protect A1 T3 1.5m x 30m

Glidevale Protect A1 T3 Roofing Underlay 1.5m x 30m

Protect A1 T3 Plus is a heavy-duty type HR roofing underlay, designed for all cold and warm pitched roofs in conjunction with the provision of ventilation at eaves and ridge. Protect A1 T3 Plus can be used with a well-sealed ceiling and a separate air and vapour control layer on the warm side of the insulation or where the ceiling is not well-sealed as in a re-roofing application.

Now in its fourth generation, this four ply, high performance underlay is best in class, originally developed to overcome the disadvantages of traditional Type 1F and 5U felts as well as second generation plastic sheet materials.

With an increased product weight of 190gsm, the robustness of Protect A1 T3 Plus ensures it can provide a secondary line of defence against wind driven rain and snow with unrestricted wind uplift use across the UK and Ireland. Being entirely waterproof, it can be used to provide temporary protection during the period the roof covering is applied.
