Cool-Vent is a venting composite insulation board that consists of a panel of rigid polyiso, a top layer of APA/TECO rated OSB or plywood, a middle layer of solid wood spacers creating a standard 1" air space. When Cool-Vent is manufactured with H-Shield F it performs as a radiant barrier. Cool-Vent is the environmentally intelligent choice for steep slope roofing applications and is viable in green and sustainable building designs.
