Glidevale Protect A1T3 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, as well as the use of a well-sealed ceiling with a separate air and vapour control layer on the warm side of the insulation.


Features and benefits:

  • 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, 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.
