Sonora® Sound Shim™

Application
Sonora® Sound Shim™ wall panels are used for acoustical absorption or directed reflection combined with strong design elements. Sound Shims™ are suitable for recording and broadcast studios and other critical listening environments.

Construction
The core construction is a ¾” dimensionally stable 6-7 PCF glass fiberboard attached at an angle to an MDO plywood backer and ribs, covered face and edges with a layer of 16-20 PCF molded fiberglass for absorption, or 1/16” un-perforated copolymer face sheet for high frequency reflection. Finishes are completely adhered to the face of the panel and returned to the back for a full finished, fully tailored edge.

Edge Detail
All edges are square and covered with molded fiberglass.

Standard Mounting
Standard mounting is Z-Clip to Wall Bar. Wall Bar to Wall Bar or a combination of Wall Bar on the top, and Velcro® on the bottom is also available.

Acoustical Performance

Fire Rating
Components, with the exception of the MDO plywood, have been tested according to ASTM E 84 and have a flame spread of 25 or less
