A drop ceiling, also known as a suspended ceiling, is a secondary ceiling that hangs below the main structural ceiling. It consists of a grid system made of metal channels that support lightweight panels, often made of mineral fiber or fiberglass. This type of ceiling is commonly used in commercial buildings, schools, and homes to hide electrical wiring, plumbing, and ductwork while providing easy access for maintenance. Drop ceilings can improve acoustics by reducing noise levels and can also enhance the aesthetic appeal of a room. They come in various styles and colors, allowing for customization to match the interior design. Additionally, LED lighting can be integrated into the grid, providing efficient illumination.
