HVAC Duct Insulation Wrap, R8, 4' x 50' (200 Sq Ft)

Increase the efficiency of your HVAC system with Ecofoil duct insulation wrap. Our R8 duct insulation is easy to install and effectively seals HVAC ducts.
EcoFoil Big 8 HVAC Duct Insulation Wrap (R-8) is specifically designed to reduce radiant heat gain and loss in residential and commercial duct applications. This insulation wrap also helps control condensation by providing an airtight thermal break around the HVAC ducting. Important - All seams must be taped so the insulation acts as a vapor barrier. We recommend taping the seams of the HVAC duct insulation with EcoFoil Premium High Tack HVAC Tape, so the product acts as one continuous sheet. Big 8 duct insulation is constructed of a triple layer of polyethylene single bubble insulation, with each layer of single bubble insulation bonded to two radiant barrier metalized sheets. The insulation is (9/16 to 5/8) thick with a large single bubble insulation in the center, sandwiched by two thin layers of single bubble insulation. Each roll of insulation duct wrap includes two rolls of spacer strips. In order to achieve the R-8 value the spacer strips must be used and placed every 2' on the ducting. This provides an additional air chamber for the insulation. When combined with the spacer strips the finished thickness is 11/16 to 3/4 thick. EcoFoil R-8 HVAC Duct Insulation Wrap is meant to be used around any duct work in your home or building. This includes round, rectangular or square ducting. It is NOT rated for exterior use.
