Bradford ThermofoilTM Medium Duty Foil is designed for use under both tiled and metal deck roofs in commercial applications and also as a wall system for domestic, industrial and commercial buildings.
Bradford ThermofoilTM Medium Duty sarking acts as a waterproofing membrane and vapour barrier when installed beneath the primary roofing material, providing a secondary barrier against moisture, wind, heat, dust penetration and condensation control under metal deck roof. Thermofoil's integral thermal insulation properties also contribute to keeping homes warmer in winter and cooler in summer.
Additionally, installation of Thermofoil Medium Duty sarking will add to the overall thermal performance of the roof and wall when a clear airspace of at least 20mm or more is provided at the reflective side of the foil face.
Thermofoil Medium Duty has a green anti-glare coating when installed to the outside of the building reduces reflection to acceptable levels. Due to its unique construction, Thermofoil Medium Duty sarking has a medium water vapour transmission rate making it suitable for light weight wall cladding applications that are batten fixed, batten thereby providing the required air space of 20mm in between cladding and the Thermofoil.
