This is a self-adhesive roll of double-bubble foil insulation, 5 inches wide and 16.5 feet long. The aluminum foil faces reflect radiant heat while the trapped bubble layer slows conductive loss, and the peel-and-stick backing lets one person wrap an AC exhaust hose without extra tape. It suits portable AC owners, HVAC duct work and anyone sealing attics, garages or windows against heat and drafts. Compared with plain foil tape it adds real bubble thickness; compared with foam pipe sleeves it is thinner and more flexible but offers less R-value per inch.

This is a self-adhesive reflective foil insulation tape made of aluminum foil bubble wrap. It has a double-bubble design and an adhesive backing, so one person can install it without extra glue or tape. The thickened build helps reduce heat loss in ductwork and blocks light from reaching the pipe.
It is used to wrap portable AC hoses, water pipes, heat exhaust ducts and HVAC ducts that need insulation. It also works in metal buildings, attics, roofs, pole barns, basements and other places that need a vapor barrier. When wrapping, overlap the tape about every 1/2 inch so the pipe is fully covered.
