Glidevale Protect A1 T3 Plus

Application

Suitable for all cold and warm pitched roofs, it can also provide a secondary line of defence against wind driven rain and snow with unrestricted wind uplift use across the UK and Ireland. It can be used to provide temporary protection during the period the roof covering is applied.

Description

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. The product 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.


Features and benefits:

  • Fourth generation high performance underlay originally developed to overcome disadvantages of traditional Type 1F and 5U felts and second generation plastic sheet materials.
  • Regularly used for new build and re-roofing schemes.
  • Completely air and watertight, achieving >2.0 m hydrostatic head of water resistance.
  • Has ‘unrestricted’ wind uplift resistance across the UK and Ireland at 345mm batten gauge (2094Pa) without the need for additional sealing tapes.
  • Excellent nail tear and tensile strength.
  • Easy to cut and handle, saving time on installation over traditional felts.
  • Does not generate nuisance noise under wind loading.
  • Absorbent under surface prevents condensate drip off.
  • UV and heat resistant.
