Hunter Panels – Cool-Vent

Cool-Vent is a ventilated insulation product that is comprised of a bottom layer of polyiso insulation, a middle layer of wood spacers with a 1”, 1.5” or 2” airspace and a top layer of OSB or plywood. The length of the rise and run determines which airspace will be the most efficient for your roofing system. Hunter Panels provides a roof ventilation calculator that takes all of these measurements and desired R-Value into account to determine the most efficient system for your building. The finished roofing system – shingles, shakes, metal or tile is installed over the Cool-Vent panels.

Cool-Vent also features cross directional airflow keeping the roof temperature constant, further eliminating hot and cold spots on the roof where ice dams are formed.
