ANC-AB1-112 Noise Barrier / Sound Absorber Composite

The barrier-backed configuration offers the benefits of both sound absorption and noise barrier products in one.  The ANC-AB1-112 consists of a silicone coated fiberglass cloth facing on 2 ” thick quilted fiberglass absorber that is bonded to a reinforced 1-lb psf loaded vinyl barrier. Curtain panels are constructed with grommets across the top and exterior grade Velcro along the vertical edges. Rolls are available 54" wide x 25' long and can be supplied with edges bound or unbound (note: barrier is 54" wide, quilt is held 3" in from each vertical edge and measures 48")

·         Class A (or 1) flammability rated per ASTM E84

·         UV resistant for outdoor applications

·         STC 32, NRC .85

Applications:

Silicon faced sound absorbers/noise barrier composites are typically used to provide maximum noise reduction by both blocking or containing noise as well as absorbing sound energey where the product may be subjected to high temperature, sunlight, water or oil. Also used as a high temperature duct wrap or on an outdoor application where maximum UV resistance is required.
