Abstract
Methods of providing flexible duct are provided. The methods include the steps of providing an inner core, the inner core having a cylindrical shape and an outer surface, providing a layer of insulation having a constant uncompressed thickness, fiber diameter and density, wrapping the layer of insulation around the outer surface of the inner core thereby forming a layered assembly, selecting an outer jacket from a set of outer jackets of different diameters, the selected outer jacket configured to compress the layer of insulation to a desired thickness and inserting the layered assembly into the selected outer jacket thereby forming flexible duct. The thickness of the compressed layer of insulation provides a desired insulative value. The outer jackets included in the set of outer jackets are configured to compress the layer of insulation into a plurality of flexible duct having different insulative values from each other.
