Acoustical Pipe and Duct Lagging:
2B Lag
A flexible two pound per square foot reinforced Mylar faced loaded vinyl noise barrier used to wrap noisy pipes, ducts, valves and fans 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 reinforced foil exterior readily accepts a matching lag tape for easy installation and also serves as a protective jacket for indoor or outdoor applications.

Acoustical Pipe and Duct Lagging:
1B LAG/QA-3
A composite material featuring a flexible one pound per square foot reinforced-foil faced loaded vinyl noise barrier bonded to a 1 thick quilted fiberglass sound absorber. Used to wrap noisy pipes, ducts, valves and fan housings.
-
Easy to cut, wrap and install with matching lag tape
-
Class A (or 1) flammability rating per ASTM E-84
-
Standard roll is 48” wide x30’ long
|
 |
|
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 as well as to provide sound absorption and thermal insulation around the pipe or ductwork. The reinforced foil facing on the barrier readily accepts a matching lag tape for easy installation and also serves as a protective jacket for indoor or outdoor applications.

Acoustical Pipe and Duct Lagging:
1B Lag/QA-9 Pipe and Duct Lag
IES - 2000s 1B Lag/QA-9 is a composite material featuring a flexible one-pound per square foot reinforced-foil faced loaded vinyl noise barrier bonded to a 2 thick scrim faced quilted sound absorber / decoupler. Used to wrap noisy pipes, ducts, valves and fan housings.
-
Standard roll is 48 wide x 30 long
-
Accepts matching Lag Tape for easy Installation
-
Class A (or 1) flammability rating per ASTM E-84
|
|
|
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 as well as to increase the sound absorption in the cavity. It also provides sound absorption and thermal insulation around the pipe or ductwork. The 2 thick quilted fiberglass absorber improves low frequency acoustical performance. The reinforced-foil exterior readily accepts a matching lag tape for easy installation.

2B Lag/QA-9 Pipe and Duct Lag
IES - 2000s 2B Lag/QA-9 is a composite material featuring a flexible two pound per square foot reinforced-foil faced loaded vinyl noise barrier bonded to a 2 thick quilted fiberglass decoupler/sound absorber. 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 also provides sound absorption and thermal insulation around the pipe or ductwork. The two-pound per sq. foot barrier and the two-inch thick quilted fiberglass absorber improves overall acoustical performance, especially at low frequencies. The reinforced-foil exterior readily accepts a matching lag tape for easy installation and also serves as a protective jacket for indoor or outdoor applications.
