R-12 Insulation Flyer
Internally Lined Duct is ALWAYS going to have superior Acoustics/Sound Attenuation than Externally Wrapped Duct. The standard Duct Liner used in the majority of commercial jobs is referred to as a Fiberglass insulation. It has always been the only method to achieve sound absorption performance.
John’s Manville’s Linacoustic® RC insulation is a preferred product in this space due to it’s superior backing on the airstream side and it’s ease of cutting during the fabrication process. Made from strong glass fibers bonded with a thermosetting resin and an airstream surface protected with JM’s exclusive Permacote® acrylic coating, it’s sold in 1/2″ thru 3″ thick and in various width increments of 3 ft, 4 ft and 5 ft to match the Galvanized metal to which it is mating.
