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 that supports lightweight panels, which can be made from materials like mineral fiber or metal. This type of ceiling is commonly used in commercial buildings, offices, and schools to hide electrical wiring, plumbing, and ductwork. Drop ceilings offer several benefits, including easy access to utilities and improved acoustics. They can also enhance the aesthetic appeal of a room by providing a clean, finished look. Additionally, they can help with insulation and energy efficiency in spaces like offices and classrooms.
