Ceiling tiles, also known as ceiling panels, are lightweight construction materials, which are used to cover ceilings, but are usually designed to improve the aesthetics and acoustics of a room. Wooden ceilings have long been regarded as the elite choice for ceiling design, due to their infinite variety and adaptability. For centuries the wooden ceiling has been a mainstay of homes and public buildings around the world, and today’s styles are no exception. Coffered ceiling is a pattern of indentations or recesses in an overhead surface. In architecture, a “coffer” is a sunken panel in a ceiling, including the interior surfaces of domes and vaults.
