Abstract
A rigid lightweight surfacing panel for providing a new surface for existing panels in acoustical panel ceiling systems, the surfacing panel having a degree of flex so to allow it to be pushed into place in a support system in underlying matched relation with an existing panel whereby a new decorative surface to impart a change in the existing decor or to decoratively replace damaged, worn or soiled surfaces can be provided without need for removing the existing panel. In a preferred embodiment porous surfacing panels are each made by combining a pair of flexible strand mats under heat and pressure with an interposed lightweight fibrous web of heat meltable binder and providing the combination with a decorative exposed surface layer which allows transmission of sound through the combination to an overlying existing ceiling panel. When called for, a concave shape can be molded into the exposed side of the panel to permit it to bear the load of an existing panel which might otherwise cause the surfacing panel to sag.
