Luna ClimaPlus acoustical ceiling tiles are long-lasting, fine-textured acoustical tiles that resist sagging. They are manufactured using a unique process that maximizes sound and anti-sag performance, producing high sound absorption and sound blocking properties. High light reflectance values translate to fewer light fixtures, lower energy costs, and reduced eyestrain. They clean easily with a soft brush or vacuum. These tiles also feature Superior Performance which means they contain a proprietary broad spectrum antimicrobial standard formulation that inhibits and retards the growth of mold and mildew.
