AudioSeal™ Absorber/Barrier Combination Blanket ABSC-25 Data Sheet
The barrier septum configuration offers the benefits of both sound absorption and noise barriers. The ABSC-25 consists of a non-reinforced 1 lb. psf loaded vinyl barrier sandwiched between two layers of vinyl-coated fiberglass cloth-faced 1" quilted fiberglass absorbers. 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 supplies with edges bound or unbound.
Typical uses include curtain panels in acoustical curtain enclosures as well as separator wall or divider partitions. The ABSC-25 blankets are commonly used to line the perimeter walls of a building.
