Our acoustical pipe & duct lag flexible noise barriers are a composite material featuring a flexible, reinforced, foil-faced mass loaded vinyl noise barrier bonded to a scrim-faced quilted decoupler/sound absorber. They are used to wrap noisy pipes, ducts, valves and fan housings. Applications: Typically used to wrap 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. The quilted fiberglass decoupler improves the performance of the noise barrier and provides sound absorption and thermal insulation around the duct or pipe. Suitable for both indoor and outdoor applications. The reinforced foil exterior readily accepts a matching lag tape for easy installation. Noise S.T.O.P.™ B-10 Lag/Noise S.T.O.P. QFA-3
