Roofshield is a unique, three-layer, nonwoven, spun-bonded, polypropylene breather membrane with a patented melt – blown core. It is intended for use as a pitched roof underlay (breathable roofing felt) and is fixed beneath tiles and slates.
Roofshield provides a secondary barrier to the ingress of rain, wind and snow. It has a low vapour resistance and is air-permeable.
Additionally, it eliminates the incidence of interstitial condensation in pitched roofs.
The product provides the most cost-effective solution for controlling interstitial condensation in a pitched roof.
