A drop ceiling, also known as a suspended ceiling, is a secondary ceiling that hangs below the main ceiling. It consists of a grid system that supports lightweight panels, allowing for easy access to plumbing, electrical wiring, and HVAC systems above. This design is commonly used in commercial buildings, schools, and offices. Drop ceilings can improve acoustics and aesthetics in a room. They come in various styles and materials, making it easy to match the decor of a space. Additionally, they can help with insulation and energy efficiency, contributing to a more comfortable indoor environment.
