ACOUSTICAL BAFFLES
In order to further reduce reflective sound,
baffles can be suspended from the ceiling. Colors and fabric selections are the
same as those for the wall panels to fit with the overall design.
TYPE I BAFFLE
Type I Baffles are comprised of one piece of a
light weight, 7 PCF glass fiber core, covered on all faces and edges with a
fabric finish. They can have square or radius edges and corners, and can be
utilized for additional sound absorption in existing spaces. Mounting is with
eye hooks.
Thicknesses: 1/2", 3/4", 1", 1-1/2", 2".
Absorption Rating: 1" x 48" x 12" -- 6.4 sabins.

are to be furnished by the contractor.
TYPE II BAFFLE
The core of the Type II Baffle is made up of
two pieces of glass fiber. Faces and edges can either have square or radius
edges and corners, and may be covered with perforated vinyl or fabric.
Applications would be for additional sound absorption. Mounting is with
D-Rings.
Thicknesses: 1", 1-1/2", 2".
Absorption Rating: 2" x 48" x 24" -- 12 sabins.
