Air Permeable Roofing Underlays

Air permeable Roofing Underlays, manufactured by Don & Low under the brand name Roofshield are unique, three-layer, nonwoven, spunbonded, polypropylene breather membranes with a patented melt - blown core.

Roofshield 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 vapor resistance and is air - permeable; additionally, it eliminates the incidence of interstitial condensation in pitched roofs.
