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. %.
