Roofshield is a low vapour resistant, air permeable and highly watertight breather membrane designed to be fixed beneath tiles and slates as a pitched roof underlay creating a secondary barrier to rain, wind and snow. Roofshield eliminates the need for a vapour control layer or ventilation hardware fitted to the roof.
Roofshield’s unique and patented meltblown core enables high levels of airflow and transport of moisture vapour from the roof space, making the formation of condensation virtually impossible and therefore eliminating the occurrence of interstitial condensation in pitched roofs.
