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.
Wrap Barrier

ANC-WB21

Acoustical Pipe

Acoustical lagging is the same product as above with a one-inch thick quilted fiberglass insulation bonded to the back of the barrier. This quilted fiberglass layer acts as a decoupler/sound absorber to improve overall noise reduction performance, as well as to offer thermal insulation (R-value = 5_. This version allows one-stop installation of the acoustical/thermal insulation layer and noise barrier.

ANC-WBV – Wrap Barrier

Acoustical Pipe

This lagging is loaded vinyl noise barrier featuring a reinforced-foil facing (aluminum faced mylar) which readily accepts a matching tape. It is supplied in 4′ wide rolls, 30′ or 60′ long. Often specified or used when the duct or pipe is already wrapped with standard insulation.

Wrap Barrier

ANC-WB42

Acoustical Wrap

This lagging is the same product as above except with a two-inch thick quilted fiberglass decoupler/absorber. This increases noise reduction performance even higher, especially for low-frequency noise problems. This version also improves the R-value to 9.
