Roofshield® continues to lead the way in roofing innovation, delivering high-performance solutions trusted by thousands of customers. Whether it’s safeguarding historical buildings or meeting the demands of modern construction, Roofshield® consistently exceeds expectations.
With a vapour resistance of 0.065 MNs/g and an Sd-value of 0.013m, Roofshield stands out as one of the most vapour-permeable membranes available.
Fully certified for both non-ventilated warm or cold roof applications since 1996, Roofshield maintains its position as the first membrane certified for use in cold, non-vented roofs.
Facilitating air movement and moisture diffusion, Roofshield prevents condensation, dealing adeptly with higher moisture levels during building drying periods.
With a certified air permeability of 34.4m3/m2 h.50Pa, Roofshield eliminates the need for additional high-level ventilation on NHBC-approved projects, ensuring consistent specifications across diverse projects.
Roofshield's air permeability ensures consistent airflow through non-ventilated roofs compared to roofs ventilated per BS5250, without elaborate ventilation hardware.
Uniquely, the BBA explicitly states that a vapour control layer is unnecessary for non-ventilated cold-pitched roof constructions using Roofshield.
Rated W1 under EN13859-1, Roofshield can endure a water column of over a meter without leakage, providing temporary weather protection to the building envelope for up to 3 months when exposed.
Independently tested and compliant across the UK, Roofshield, without the need for high-level ventilation or a vapour control layer, remains the simplest and most cost-effective method to meet regulatory standards.
