ANC-AB110EXT-R Sound Curtains

ANC- AB110EXT-R offers the benefits of both a noise barrier and a sound absorber composite in one product for outdoor applications.  This barrier-backed product consists of an exterior grade, UV resistant heavy-duty faced quilted fiberglass absorber bonded to a one-pound per sq. ft. reinforced loaded vinyl barrier. The heavy-duty facing is a 10 oz per sq yd vinyl-coated polyester (VCP) quilted to the sound absorber rather than the standard 4.5 oz. facing. noise blocking curtains panels are constructed with grommets across the top and bottom, exterior grade Velcro seals along the vertical edges, and are sewn with Gore Tenara exterior grade thread.

Typically used as modular curtain panels on long-term construction projects or permanent outdoor applications such as enclosing HVAC equipment, dust collectors, or similar machinery behind a manufacturing plant where UV and abuse resistance as well as maximum durability, longevity, and noise blocking curtains are required. Also available with a one-inch thick quilted fiberglass absorber, or with a two-pound per sq. ft. reinforced barrier.

  • STC 29 Rating, NRC .70
  • Available facing colors on the quilt: gray, tan, black, off-white
  • Available barrier colors: gray, tan, olive drab or blu
