Acoustical Wrap Barriers

Acoustical Lagging Products: Acoustical Wrap Barrier; Acoustical Pipe & Duct Material

Wrap duct lagging around noisy pipe and duct work to dramatically reduce the amount of noise transmitting through the walls or casing of duct-work, steel or PVC piping, valves, sheet-metal enclosures, plenums, VAV units and fans.

Our 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.

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 duct or pipe is already wrapped with standard insulation.

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 acoustical/thermal insulation layer and noise barrier.

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

Duct Lagging Features

• STC ratings fo 26-30
• Easy to cut and install

Installation Instructions:  Use tape or clamps to affix the duct lagging material around the circumference of your duct work or piping. Ask us about a mylar matching tape available to disguise the seams. This is sold in 54″ X 30 ft. roles as an add on product to the duct wrap. Simply wrap standard pipes or vents with this material. Cut to fit and wrap with matching tape. Custom wrap sizing is available upon request.Size: 4’ X 4’ standard.
