Wet-Felted Acoustical Ceiling Tile and Panels

Expanded perlite (40-50%) is also present in a unique wet-felted acoustical tile and ceiling panel composition. It has been presented that expanded perlite is favorable in the production of ceiling tiles and panels to reduce the tendency to retain water in a composition containing expanded perlite, mineral wool, and a secondary binder such as starch or clay.
