A suspended ceiling, also known as a drop 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. This type of ceiling is commonly used in commercial buildings, schools, and offices to hide electrical wiring, plumbing, and ductwork while providing easy access for maintenance. Suspended ceilings can improve acoustics and reduce noise levels in a room. They are available in various materials, colors, and designs, allowing for customization to match the interior decor. Additionally, they can enhance energy efficiency by providing insulation and reducing heating and cooling costs.
