BBC-
EXT-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. Curtain 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.
