Abstract: A ceiling panel having an upper face, a lower face opposite the upper face, and first through fourth edges having a first edge portion adjacent the upper face and a second edge portion below the first edge portion. Each of the first and second edges may have a tongue and each of the third and fourth edges may have a groove. The first edge portion of each of the third and fourth edges may include a first flange having a distal surface. The first edge portion of each of the first and second edges may include a first recess having a first recess wall surface. The first flange may nest within the first recess of an identical adjacent ceiling panel with the distal surface of the first flange of the ceiling panel being spaced from the first recess wall surface of the first recess of the identical adjacent ceiling panel.

Abstract: A panel which may be used as a part of a surface covering system, such as that for a wall or a ceiling, and which is useful to provide easy installation, durability, beneficial fire preventive performance, resistance to mold growth, and resistance to moisture. The panels may have a first major surface, a second major surface opposite the first major surface, and a side surface extending between the first and second major surfaces. The panel may be formed from polyvinyl chloride present in an amount from about 45 to about 70 wt. %; carbonate present in an amount from about 10 to about 31 wt. %; stearate present in an amount from about 1 to about 6 wt. %; and aluminum hydroxide present in an amount from about 10 to about 30 wt. %.
