Abstract
Abstract A substantially square frame made of wire is covered on one side or both sides with a skin of metal foil or thin metal sheet, preferably aluminum, or thin plastic film. The skin is secured on the frame by adhesive means, such as heat sealing. The surface of the skin may be treated by wrinkling, embossing, perforating, printing, coloring or other suitable decorating process. The thus obtained lightweight tile is usable for decorating ceilings, either suspended below or in conjunction with sound absorbing materials such as glass fiber or mineral wool.
