A composite material featuring a flexible one-pound per square foot reinforced Foil-faced faced loaded vinyl noise barrier bonded to a 1" thick quilted fiberglass sound absorber adhered to a 1/8" mass loaded vinyl barrier.
Used to wrap noisy pipes, ducts, valves and fan housings. Typical uses include: wrapping noisy pipes and ducts to block the noise that transmits through the walls of the pipe or duct as air or other contents move through it as well as to increase the sound absorption in the cavity. It also provides sound absorption and thermal insulation around the pipe or duct work. The reinforced Foil-faced exterior serves as a protective jacket for indoor or outdoor applications.
