Protect Wunderlay Membrane Brochure

Protect Wunderlay is a lighter 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. Protect Wunderlay 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.
