Acoustical Lagging is wrapped around the outside of duct or pipe to reduce the radiated noise transmitting through the
walls of the ductwork or piping. It is different from, and often used in conjunction with, a duct liner that is installed inside
a duct to reduce noise exiting from downstream registers and vents.
