Suspended ceilings are often known as "dropping ceilings" or "fake ceilings." They are hung from the structure above, generally a roof or slab, as the name indicates. This creates a gap between the structure's underbelly and the ceiling's upper surface. Fluid can seep through this gap and into the space below. If it does not escape through venting, then it will cause damage to the building's interior. False ceilings are decorative panels used to cover large open spaces in buildings. They can be made of wood, metal, or plastic and are designed to look like the ceiling of a room. False ceilings are used instead of real ceilings because they are easier to maintain and less expensive to replace if damaged. The main difference between a suspended ceiling and a false ceiling is their use. With a suspended ceiling, there is no floor beneath it except for small obstructions such as light switches and thermostat controls. This means that anyone who walks across it could be injured by a sudden drop-off without warning. A false ceiling is built on a floor that can be made of concrete, ceramic tiles, or any other type of surface that doesn't require padding underneath it. There are several different types of suspended ceilings, including grid-suspended, truss-suspended, tube-shaped, and pyramid-shaped.
