A false ceiling is a secondary ceiling that is suspended below the main ceiling of a room. It is also known as a drop ceiling or a suspended ceiling. False ceilings are often used to hide electrical wiring, pipes, and ductwork, and to reduce the height of a high ceiling. They can also be used to create an acoustic barrier or to add an aesthetic element to a room by incorporating decorative elements such as lighting or 3D tiles. False ceilings are usually made of lightweight materials such as gypsum board, mineral fiber, or metal. They are supported by a framework of metal or wooden beams and are suspended from the main ceiling using wires. False ceilings can be easily installed and removed, making them a popular choice for commercial and residential buildings.
