Noise S.T.O.P. Soundproof Blanket

Noise Barrier/Sound Absorber Sound Blanket

BBC-EXT-R-2 Noise Barrier/Sound Absorber Sound Blankets

BBC-EXT-R-2 offers the benefits of both a noise barrier and a sound absorber composite in one product. This BBC exterior sound absorbing blanket 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 outdoor soundproofing panels are constructed with grommets across the top and bottom and exterior grade Velcro seals along the vertical edges.
