Noise S.T.O.P.™ B-10 Lag/NS QFA-9 & QFA-3 Pipe & Duct Lag
Foil Faced Pipe and Duct Lag
LAG-Series Flexible Noise Barrier

  • Standard Roll is 54″ Wide × 30′ Long
  • Accepts Matching Lag Tape for Easy Installation
  • Class A (or 1) Flammability Rating Per ASTM E-84

B-10 Lag/NS QFA-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.

Quilted Fibrerglass Absorber Pipe and Duct Lag
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.
