Glidevale Protect Wunderlay
Application

Protect Wunderlay provides a secondary line of defence against wind-driven rain and snow and resistance to wind uplift. It can be used as a temporary roof covering.

Description

Protect Wunderlay is an alternative to Protect A1 type HR roofing underlay, developed to overcome the disadvantages of traditional Type 1F and 5U felts and second generation plastic sheet materials. It has good strength and nail tear resistance and is independently certified by BM TRADA.


Features and benefits:

  • Completely water and airtight.
  • UV and heat resistant.
  • Good nail tear and tensile strength for its weight.
  • Does not generate nuisance noise under wind loading.
  • CE marked and BM TRADA certified.
  • Absorbent under surface prevents condensate drip off.
  • Embossed dark grey upper surface reduces glare and takes a chalk line marking.
  • Easy to cut and handle.
  • Suitable for wind uplift zones 1 to 4 to BS 5534 (at 345mm batten gauge) in the UK and Ireland.
