Abstract
Abstract An acoustical panel assembly having improved structural, decorative and acoustical properties is disclosed. The panel assembly includes a perimeter frame. A thin septum member is supported in the center of the frame. A fibrous glass layer is positioned adjacent each side of the septum member. A molded, semi-rigid, fibrous glass diffuser member is positioned adjacent each of the fibrous glass layers. The assembly includes means for joining adjacent panel assemblies and, in one embodiment, an outer decorative fabric layer is positioned adjacent each of the outer surfaces of the diffuser members.
