Roofshield® is a three-layer, non-woven, spunbonded, polypropylene breather membrane with a patented melt-blown core. Installed beneath tiles and slates, it provides a secondary barrier to the ingress of rain, wind and snow while it also has a low vapour resistance and is air-permeable.
It is intended for use as a pitched roof underlay and eliminates the incidence of interstitial condensation in pitched roofs.
The combination of low vapour resistance and air permeability eliminates the need for low- and high-level ventilation. It also means that a vapour control layer or air barrier does not need to be fixed at ceiling level. This is a basic requirement with other inferior performing products, which are air-impermeable and have a significantly higher vapour resistance.
Roofshield provides a cost-effective solution to controlling interstitial condensation in a pitched roof. The exclusion of ventilation and a vapour control layer eliminates the additional expense of buying extra components and paying installation costs.
