Abstract
A flexible insulation material and method for using such an insulation material with an HVAC duct to provide noise suppression and thermal protection. The insulation material includes a lofted substrate and a facer sheet laminated thereto. The substrate contains nonwoven lofted fibers and the insulation material is attached to the duct such that a first surface of the substrate faces a wall surface of the duct and the facer sheet is on the opposite surface of the substrate. The facer sheet includes a polymeric film bonded to the substrate, a metallization layer on the polymeric film, and optionally a protective coating on the metallization layer. The insulation material can be used as an external duct wrap or an internal duct liner. In the former application, the insulation material preferably includes a second facer sheet on the first surface of the substrate.
