Steep Slope Applications
- 3:12 and greater - Cool-Vent, a vented, nailable polyiso insulation panel
- 3:12 and smaller - H-Shield NB, a non vented polyiso panel bonded to OSB
- Below is a pdf of the installation and design criteria guide for each product.
Cool-Vent is a venting composite insulation board that consists of a 4'x8' panel of rigid polyiso, 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 the environmentally intelligent choice for steep slope roofing applications and is viable in green and sustainable building.
