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.
