A false ceiling is a secondary ceiling installed below the main ceiling. False ceilings were first used in the Muromachi period in Japan in 1337 for aesthetic purposes and in London in 1596 to aid acoustics. False ceilings are made of various materials like gypsum boards, metal panels, plywood, PVC, and can be installed using exposed grid, concealed grid, semi-concealed grid, or open cell techniques.
