16 in. x 12 ft. Insulated Flexible Duct with Metalized Jacket - R8

A:  I used it on an attic exhaust fan, because my fan was located above the garage....but I wanted to suck the hot air from the house attic....not the garage attic....so I ran this duct to the area from which I wanted to pull the hot air. Commercial furnace installers put a similiar product in my shop building 25 years ago as heat ducts on a natural gas furnace....so, I would guess it would work for your application....

A:  Yes it connected to furnace, we have to replaced our because the person who live it the house it use to smoke so replaced all the duct in the house.

A:  I used this duct tape as a return duct because the unit was subdimensioned with the old one ( 14" ) and was whistling. Not anymore!

A:  Previous answer is wrong, if total diameter is 20" less 2" of insulation all around this means inner diameter is 16"
