Acoustical Duct and Pipe Wrap for HVAC Noise Control, Sound Barriers, Absorber-Barrier Combination, Mass Loaded Vinyl.
Duct and Pipe Wrap is used to wrap ductwork and pipes to dramatically reduce the amount of noise transmitting through the walls or casing of ductwork, steel or PVC piping, valves, sheet metal enclosures, plenums, HVAC units, and fans.
Pipe & duct lagging is easy to cut, trim and install on any site and is ideal for industrial and residential noise alike. Simply wrap this acoustical pipe barrier around any cylinder containing noisy air or liquid flow, and tape the seams shut: you will see 15 to 20-decibel level drop in unwanted noise.Size: 54″ X 30’ 1″ thick.
