Duct Lagging

Duct Lagging

Duct Lagging is typically used to wrap noisy pipes and ducts, and thus help to block the noise contents moving through he pipes. From air flow to liquid content, duct lagging helps to increase sound absorption in the cavity and provides thermal insulation as well.

Types of duct lagging that include a foil-faced reinforced exterior will readily accept a matching lag tape for easy installation. The foil-face also serves as a protective jacket for indoor or outdoor applications. The 2# per sq. foot barrier and the 2″ thick quilted quilted fiberglass absorber improves overall acoustical performance, especially at low frequencies.
