Vent and Duct Insulation
Insulation products for vent and duct systems keep the cooled or heated air in HVAC ducts closer to the intended temperature, and help to ensure greater energy efficiency by preventing air leaks. This insulation covers the exteriors of ductwork and other HVAC components. Duct insulation varies by thickness and width, as well as by format, such as board or roll. It also varies by material, such as fiberglass, cotton, or polyester. Other notable distinctions between products concern which standards they satisfy, their R value, and their jacket material. Supplement your insulation efforts by sealing your ductwork first with duct sealant or duct tape to ensure the most energy-efficient insulation of vents, ducts, and other HVAC components.
