Roofshield
NHBC accept Roofshield without ventilation.
Roofshield 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 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 combination of low vapour resistance and air - permeability eliminates the need for low and high level ventilation. It also negates the need for a vapour control layer or air barrier 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.
The product provides the most 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 for the labour to install them.
