ISO 3™
ISO 3™ is a rigid roof insulation board composed of a closed cell polyisocyanurate foam core bonded in the manufacturing process to universal fiber glass reinforced facers.
ISO 3 utilizes an environmentally compliant blowing agent containing pentane hydrocarbon to enhance the thermal performance of the foam insulation. This hydrocarbon has zero ozone depletion potential and conforms to the Montreal Protocol established in 1987.
ISO 3 meets the physical property requirements of ASTM C 1289-02 Type II, Class I, Grade 2 and CAN/ULC S 704. ISO 3 specialty products are also available as tapered panels, pre-cut miters and pre-cut crickets.
