Bradford ThermofoilTM Heavy Duty Foil is a premium strength, heavy duty plain foil often adhered to Glasswool and Rockwool bulk insulation to satisfy the requirements of air conditioning industry to externally wrap ductwork, vessels and (SPI) sectional pipe insulation.
Bradford Thermofoil Heavy Duty Foil is a heavy duty plain aluminium foil often used for facing Glasswool and Rockwool bulk insulation. It consists of two layers of aluminium foil and kraft papers bonded with flame retardant adhesive, with additional strength provided by reinforced fibreglass scrim.
Applications
Bradford ThermofoilTM Heavy Duty acts as a waterproof sarking when installed beneath the primary roofing material, providing a barrier against moisture, wind, heat, and dust penetration. Thermofoil's integral thermal insulation properties also contribute to keeping homes warmer in winter and cooler in summer.
Additionally, installation of Thermofoil Heavy Duty sarking will add to the overall thermal performance of the domestic, industrial and commercial buildings, cold stores and cool rooms when a clear airspace of at least 20mm or more is provided at the reflective side of the foil face. It improves light diffusion and utilisation when used as an exposed internal roof lining.
Due to its unique construction, Thermofoil Heavy Duty has a low water vapour transmission rate making it an excellent vapour barrier for facing bulk insulation and SPI pipe sections. An ideal reflective facing for Glasswool and FibertexTM Rockwool, Thermofoil Heavy Duty is suitable for applications where high tensile strength and impact resistance is required.
