ISOGARD™ GL polyiso insulation boards have a glass-reinforced facer on both sides of the foam core and are designed for use in a range of commercial roofing installations. This versatile insulation is especially suited for FM Approved and UL Classified direct-to-deck applications and assemblies, without an additional thermal barrier in most installations.
ISOGARD GL can be attached with hot asphalt or low-rise foam adhesive to various substrates, or mechanically fastened with Elevate fasteners and plates. Because the board can be installed direct-to-deck in many applications, it may help reduce the need to adhere it to another insulation layer.
