PIPE & DUCT LAGGING

Pipe & Duct Lagging

 

Pipe & Duct LaggingAcoustical Pipe and Duct Lagging is the best solution for wrapping noisy pipes, ducts, valves and heat exchanges in a variety of indoor and outdoor applications.

Acoustical pipe and duct wrap combines a 1 lb per sq. ft. or optional 2 lb per sq. ft. mass loaded vinyl noise barrier with a scrim reinforced foil facing on one side, and commonly bonded to a 1 inch or 2 inch thick quilted fiberglass decoupler/absorber to improve acoustical performance. The reinforced pipe wrap facing accepts a matching tape for quick and easy installation. The quilted fiberglass decouples the loaded vinyl noise barrier from the noise emitting surface, creating a floating noise barrier to achieve optimum noise reductions.

Not to be confused with duct liner, acoustical lagging is wrapped around the outside of a pipe or duct to reduce noise that transmits through the walls or skin of that pipe or duct. Duct liner is different; it is used inside of ductwork only to absorb the noise that comes out of any vents or openings in the duct.
