Hunter Panels offers Cool-Vent, a rigid roof insulation panel composed of polyisocyanurate foam core manufactured as a ventilated nailbase roof insulation panel. Cool-Vent is an environmentally friendly product constructed with a top layer of APA-rated OSB or plywood, a middle layer of wood spacers and a bottom layer of polyiso foam insulation. The vent is ideal for a variety of steep-slope applications, including post and beam construction and log homes. It has a standard one-inch air space, which allows airflow in all directions to give improved cooling and ventilation while decreasing moisture vapor and heat build-up, saving energy in the building.
