Sandrift ClimaPlus acoustical ceiling panels are medium, uniquely textured acoustical panels that produce sag-resistant, custom ceiling designs. They are made with a cast process that enhances the surface appearance and provides excellent sound absorption and durability. The cast process also results in integral color throughout each panel, a quality that masks nicks and scratches. Their long-lasting, abuse-resistant surfaces resist scrapes and clean easily with a brush or vacuum. These panels also feature Superior Performance which means they contain a patented broad-spectrum antimicrobial standard formulation that inhibits and retards the growth of mold and mildew. The panels feature high noise reduction coefficients (NRC) and Ceiling Attenuation Class (CAC) values. A backing acts as a sound barrier and resists breathing (air passing through the surface), so the surface stays cleaner longer. The panels are classified as zero-emitting. Class A fire rated. In addition, the panels offer a ClimaPlus 30 year system warranty to withstand temperature and humidity conditions up to 104 deg. F. (40 deg. C.)/95% relative humidity without visible sag when used with a USG DONN Suspension system. Class A. Size: 2 Ft. x 2 Ft. x 3/4 In. Edge: shadowline. Medium texture. 8 pieces or 32 Sq. Ft. per case.
