Abstract
A flexible air duct contains a uniformly-spaced reflective insulation system, with or without bulk insulation, a liner, and an outer jacket that would allow a reduced amount or no amount of bulk insulation to be used to obtain a desired R-value insulation. The flexible air duct can be used to move conditioned air to one or more desired locations.
