I bought this to cover the portable AC vent hose. The duct cover really worked to keep the heat from the hose out of the room. Had to cut the vent cover and wrap it around the hose and secure with duct tape.

Very useful in HVAC duct retro-fits

Used this product on a recent duct retro-fit rather than wrapping the duct with blanket insulation and taping such. Five (5) foot lengths are compatible with the 5 foot lengths of duct pipe and seaming the joints with Premium Foil UL Listed HVAC Tape made for an almost invisible joint. Only cheaper way I found was to buy a 25 foot roll of flexible duct and remove the inner wire duct core, which also gives you the option for insulation lengths longer than five feet. For easier installation be sure to purchase a 'end cap' to place over the duct end which makes installation and sliding of the sleeve so much easier.
