Abstract
A flexible HVAC duct is made with a support structure-containing duct liner, insulation layer, and reinforcing layer-containing vapor barrier. At least the duct liner and vapor barrier are constructed of polymer materials that enable them to be placed in the same recycling stream once the flexible HVAC duct is removed from its installed location. The insulation layer can also be made of a polymer material compatible with that used for the duct liner and vapor barrier so that the entire duct can be recycled once removed.
