Vented Nailboard™
Vented NailBoard™ is a rigid roof insulation board composed of a closed cell polyisocyanurate foam core attached with spacers to 7/16" (11 mm) or 5/8" (16 mm) oriented strand board (OSB) on one side and a universal fiber glass reinforced facer on the other. The polyiso component of Vented NailBoard 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.
Vented NailBoard meets or exceeds ASTM C 1289-02 Type II, Class I, Grade 2 and CAN/ULC S704.
