R-8 HVAC Duct Wrap Insulation - 4' x 50' (200 Sq Ft)

EcoFoil R-8 HVAC Duct Wrap Insulation is specifically designed to reduce radiant heat gain/loss in residential and commercial duct applications. The insulation also helps control condensation by providing an airtight thermal break around the HVAC ducting. All seams must be taped so the insulation acts as a vapor barrier.This 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 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 Wrap Insulation 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.Important - You must tape the seams of the insulation with EcoFoil Premium High Tack HVAC Tape, this way it acts as one sheet and maintains the moisture barrier.
