FLAMESTOP® 138 is an 8-layer double sided aluminium foil laminate with superior radiant heat reflective properties for use as roofing insulation and as a highly effective vapour barrier with air-conditioning ductwrap.
FLAMESTOP® 138 is manufactured by extruding 2 layers of high strength kraft paper and 2 layers of aluminium foil and heat-welding them together with a 3-way fibreglass reinforcing scrim and 3 layers of copolymer resin to form a perfectly sealed, scratch resistant laminate.
