Roofshield®: The Benchmark for Breathable Roofing Membranes
Roofshield® is Don & Low’s flagship roofing underlay, recognised as a market leader in air and vapour-permeable membranes.
Manufactured exclusively by Don & Low in Forfar, Scotland, Roofshield® has been at the forefront of air and vapour-permeable roofing underlays for nearly three decades. It's advanced design offers a combination of strength, breathability, and ease of installation.
Key Features and Benefits of Roofshield®
Vapour Permeability: 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.
Air Permeability: Facilitating air movement and moisture diffusion, Roofshield prevents condensation, dealing adeptly with higher moisture levels during building drying periods.
No Vapour Control Layer (VCL) Required: Uniquely, the BBA explicitly states that a vapour control layer is unnecessary for non-ventilated cold-pitched roof constructions using Roofshield.
Enhanced Weight and Strength: At 196 grams per square metre, Roofshield offers durability and robust performance.
Certified Performance: Roofshield is fully certified by the BBA for use in both non-ventilated warm and cold roof applications. It is also endorsed by the NHBC, and is BS5534 compliant.
Water Resistance: 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.
Uniform Airflow: Roofshield's air permeability ensures consistent airflow through non-ventilated roofs compared to roofs ventilated per BS5250, without elaborate ventilation hardware.
Trusted Across Projects and Climates
Since it's launch in 1996, Roofshield has been specified for a wide range of projects, from heritage restorations to new builds. It has proven its reliability in diverse climates, including the challenging conditions of the Antarctic. Its flexibility and robust performance make it suitable for both non-ventilated warm and cold roof applications.
