The USG Ceilings Tabaret ClimaPlus 209 2 ft. x 4 ft. Lay-in Ceiling Tiles (3-Pack) are medium-textured, vinyl face-laminated, fiberglass acoustical panels that resist sagging. They offer excellent sound control performance by providing high sound absorption. A lightweight fiberglass base mat makes installation easy. The moisture resistant, vinyl surface is washable, making them suitable for high humidity areas. Additionally, these panels feature inherent performance which means that due to the fiberglass substrate these panels inherently resist the growth of mold and mildew.
