Cool-Vent is a venting composite insulation board that consists of a 4'x8' panel of closed cell rigid polyisocyanurate, a middle layer of solid wood spacers, creating a standard 1" air space and a top layer of APA/TECO rated OSB or plywood. Cool-Vent is theenvironmentally intelligent choice for steep slope roofing applications and is viable in green and sustainable building designs. Hunter Cool-Vent is a high-performance roof insulation system designed for superior thermal efficiency, ventilation, and structural strength. Each panel features a durable 3/4 in plywood sheathing factory-bonded to rigid foam insulation, creating a single product that is strong, moisture-resistant, and energy-efficient. Multiple thickness options are available to suit different R-values and project needs. Key Features Factory-laminated 3/4 in plywood to rigid foam insulation Provides continuous insulation and integrated ventilation Enhances energy efficiency and reduces heat transfer Protects roofing systems from moisture damage Available in various thicknesses for different performance levels Easy to install, saving time and labor on-site Total Thickness Panel Size Plywood Thickness Foam Thickness Sheets/Pallet Total Sq Ft/Pallet 2.7 in 4 ft × 8 ft 3/4 in 1 in 17 544 sq ft 3.2 in 4 ft × 8 ft 3/4 in 1.5 in 14 448 sq ft 3.7 in 4 ft × 8 ft 3/4 in 2 in 15 480 sq ft 4.2 in 4 ft × 8 ft 3/4 in 2.5 in 11 352 sq ft 4.7 in 4 ft × 8 ft 3/4 in 3 in 10 320 sq ft 5.2 in 4 ft × 8 ft 3/4 in 3.5 in 9 288 sq ft
