Suspended ceilings, also known as drop ceilings, are a type of ceiling that hangs below the main structural ceiling of a room. They consist of a grid system made from metal or other materials, which supports lightweight panels. This design allows for easy access to plumbing, electrical wiring, and HVAC systems, making maintenance simpler. These ceilings are commonly used in commercial buildings, such as offices and schools, due to their versatility and aesthetic appeal. They can improve sound insulation and can be customized with various materials and colors to match the decor. Additionally, suspended ceilings can help with energy efficiency by providing insulation.
