What do you do when you need insulation and ventilation outside of a structural roof deck, such as vaulted and log home applications, post-and-beam construction and cathedral ceilings?
Hunter Panels, Portland, Maine, offers one of the many products on the market to address these issues. Cool-Vent is a rigid roof insulation composed of a closed-cell polyisocyanurate foam core manufactured as a ventilated nailbase roof insulation panel. The product is constructed with a top later of APA-rated 7/16-inch OSB, a middle layer of wood spacers and a bottom layer of polyisocyanurate foam insulation. It has a standard 1-inch ventilation space that allows for airflow in all directions, helping to decrease moisture vapor and heat build-up, thus improving the overall efficiency of the building.
