A drop ceiling, also known as a suspended ceiling, is a type of ceiling that is hung below the main structural ceiling. It consists of a grid system made of metal channels that support lightweight panels, which can be made from materials like mineral fiber or fiberglass. This design allows for easy access to plumbing, electrical wiring, and HVAC systems located above the ceiling. Drop ceilings are commonly used in commercial buildings, such as offices and schools, because they provide a clean, finished look while also improving acoustics and insulation. They can be easily installed and modified, making them a practical choice for spaces that require flexibility in design and functionality.
