Abstract
Abstract A decorative acoustical ceiling panel is disclosed comprising a rigid rectangular frame member having a rectangular layer of carpeting material held peripherally therein and provided with a backing of fire-resistant reinforcing composition including integral reinforcing members to provide a flat, sag-proof panel. The panels are adapted to be assembled with other like panels in edge-to-edge relationship in a suitable ceiling installation and provide the appearance of a blanket of carpeting covering the ceiling. Mounting means in the form of hook members comprising extensions of the reinforcing members extend from the upper edges of the frame member for mounting the panels on support members suspended from a ceiling. A method of fabricating the panels is also disclosed which imparts the desired rigidity without buckling and with the use of the least amount of reinforcing cement.
