Noise S.T.O.P.™ LAG-Series Flexible Noise Barriers

LAG-Series acoustic pipe and duct lagging 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. This acoustic insulation is used for noisy HVAC systems, pipes, ducts, valves and fan housings.
  • Standard Roll is 54″ Wide × 30′ Long
  • Accepts Matching Lag Tape for Easy Installation
  • Class A Fire Rated per ASTM E84
Our acoustic pipe insulation and duct lagging 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. This acoustic insulation is used for noisy HVAC systems, pipes, ducts, valves and fan housings. Acoustic Lagging Applications: This acoustic pipe insulation and duct lagging is 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. This HVAC insulation wrap is suitable for both indoor and outdoor applications. The reinforced foil exterior readily accepts a matching lag tape for easy installation.
