Decoustics Combines Products to Optimize Acoustics and Beauty at Middle Tennessee State University. For a new 840-seat ballroom at the Middle Tennessee State University student union in Murfreesboro, Tenn., the architect specified a ceiling consisting of large, two-tones arched rectangular panels in a variety of sizes. To create the custom panels, Decoustics merged two products – Claro, a fiberglass acoustical panel with a smooth white surface with Quadrillo, a cut-out wood acoustic panel serving as a border around the fiberglass. To achieve the challenging arc pattern, Decoustics constructed a physical mock-up of the design to ensure the grid and panels followed the exact radius, and worked closely with ceilings contractor for installation.
