Thermofoil heavy duty foil is a heavy weight plain aluminium foil often used for facing Glasswool, Rockwool and polystyrene insulation. It consists of two layers of aluminium foil and paper laminate, bonded with a flame retardant adhesive and reinforced with fibreglass woven in a square pattern to provide high strength and serviceability.
Installation of Thermofoil heavy duty foil will add to the overall thermal performance of the commercial and industrial buildings and it acts as an excellent vapour barrier for facing bulk insulation or pipe section insulation.
