Abstract: This invention is related to a lightweight composite panel and a method of making the same. The lightweight composite panel is used in the construction of cabinets and furnishings where weight must be kept to a minimum. The lightweight composite panel includes a top skin panel, at least one core frame, a bottom skin panel, and a lightweight material. The core frame is assembled from flat members that form the perimeter of the lightweight composite panel, while the top and bottom skin panel form the planar sides of the panel. The lightweight material is shaped to fill the cavity created by the top and bottom skin panels and the core frame. The components of the lightweight composite panel are pressed between corresponding mold halves, thereby taking the shape of the mold halves and forming a contoured lightweight composite panel that has the appearance of a traditional solid panel.

Abstract: An acoustical divider panel and a frame for such panel are provided in which top and bottom frame members of equal length and opposed side frame members of equal length are joined at their ends by a miter joint to form a rectangular frame. Each of the four members are formed of a U-shaped channel opening outwardly from the frame and each of the edges of said channels are provided with an outwardly facing grooved channel extending along its length for receiving the edges of a sheet of fabric. The interior of the grooved channels contain an undercut portion adapted to secure the edges of said fabric and welting. The frame is preferably formed with one of the frame members at each of said miter joints having an extended outer edge, whereby the amount of offset between said adjoining members can be adjusted.
