The barrier septum configuration offers the benefits of both sound absorption and noise barriers. The ABSC-26 consists of a non-reinforced 1 lb. psf loaded vinyl barrier sandwiched between two 1" thick absorbers with a silicone-coated fiberglass cloth. Curtain panels are constructed with grommets across the top and Velcro along the vertical edges. Rolls are available 4' wide x 25' long and can be supplied with edges bound or unbound.
Silicone faced quilted fiberglass absorbers are typically used to reduce reverberant noise energy within a piece of equipment, room or building where the product may be subjected to high temperature, sunlight, water or oil.
