Roofshield, launched in 1996, is a vapour- and air-permeable underlay (VPU) for pitched roof applications. It is a unique, three – layer, nonwoven, spunbonded, 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. Fully certified for use in non-ventilated warm or cold roof applications.
