Duct Lagging and Acoustical Pipe Wrap for Noise and Sound Control by ArtUSA

Acoustic Duct Lagging is a lagging, composite material that is 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.

Specification B-10 LAG QFA 3 our best selling and most most typical pipe wrap

The barrier shall be constructed of a [2 mm (.10")] thick barium sulphate loaded limp vinyl sheet bonded to a thin layer of reinforced aluminum foil on one side. The barrier shall have a nominal density of (4.8 kg/m3) (1 psf) and shall have a minimum STC rating of 28. The barrier shall exhibit minimum flammability ratings of 0.0 seconds for flame out and afterglow and 0.2 inches for char length when tested in accordance with Federal Test Std. No. 191-5903. The barrier shall have a minimum thermal conductivity “K” value of 0.29 and a rated service temperature range of 40°F (-40°C) to 220°F (105°C). When tested for Surface Burning Characteristics per ASTM E84, the barrier will have a Flame Spread Index of no more than 10 and a Smoke Development Index of no more than 40.

The decoupling layer shall be a combination of 1" (25mm) fiberglass batting, non woven porous scrim-coated glass cloth, quilted together in a matrix of 4" (100 mm) diamond stitch pattern which encapsulates the glass fibers. The composite material shall be fabricated to include a nominal 6" (152 mm) wide barrier overlap tab extending beyond the quilted fiber glass to facilitate a leak-tight seal around field joints. Nominal barrier width 54” (1372 mm), nominal decoupler width 48” (1219 mm).

Features ...

Available with a 1" or 2" quilted decoupler
Meets Class A flammability
Suitable for indoor or outdoor applications
Easy to cut and install
ArtUSA flexible lag series combines a loaded vinyl barrier with foil facing on one side. When a quilted fiberglass is added to the lag barrier it acts as a decoupler to form a tight fitting "floating" noise barrier.

Fire Rated Indoor or Outdoor Noise Barrier Material
Barrier Overlap Tab for Fast, Noise-Tight Installation

Designed for indoor or outdoor use, pipe/duct lag material meets Class 1 requirements for smoke development and flame spread when properly installed. The composite material is designed to reduce the sound transmission of piping, ductwork and equipment housings greater than achieved by adding mass alone by combining a fire rated limp mass with a decoupling quilted fiber glass lining. Applications Include: pipeline noise from fluid or gas pulsation in chemical, petrochemical and waste water treatment plants and industrial processes in addition to pressure reducing stations, HVAC duct and mixing boxes and other similar applications. The material is constructed of a rugged reinforced aluminized-faced loaded limp mass vinyl bonded to a scrim-faced quilted fiber glass absorber/decoupler. The vinyl provides mass and flexibility, while the aluminum adds increased mechanical strength, weatherability, attractive appearance and improved fire retardancy. To decouple the mass layer from the noise or vibration source, quilted absorber is used. 1 inch (25 mm) thick absorber layer consists of fine fiber glass batting sewn in a diamond pattern to a non-woven, porous glass fiber scrim cloth to encapsulate the glass.The non-lead composition of the barrier material allows for safe handling and easy installation. When applied with quilted absorber, fire-resistant barrier material is simply cut to length, wrapped around the pipe or duct and fastened with adhesive, tape, mechanical fasteners or bands. Rolls are manufactured with an additional 6" (152 mm) width of barrier on one side to provide an overlap of adjacent application and an improved acoustical seal. In some locations, codes may preclude the use of vinyl materials in this application.
