ANC- AB23 (2#, 3”) Noise Barrier/Sound Absorber Composite

 

The barrier septum configuration offers the benefits of both sound absorption and noise barriers.  A 2 lb psf loaded vinyl barrier is sandwiched between one 1” and one 2” layer of quilted fiberglass absorbers. Curtain panels are constructed with grommets across the top and hook and loop fasteners along the vertical edges.  Rolls are available 4’ wide up to 25’ long and can be either bound or unbound.

·       Class 1 or A per ASTM E 84

·       STC rating 33

·       NRC rating 0.85

·       Available colors: gray, white, black, or tan

 

Applications:

Typical uses include curtain material in acoustical curtain enclosures.  Also used as separator walls or divider partitions.  Commonly used to line the perimeter walls of a building to significantly increase the transmission loss ability of the wall as well as to add sound absorption inside the room.
