Ceiling types refer to the various styles and designs used in the upper interior surface of a room. Common types include flat ceilings, which are simple and easy to install, and vaulted ceilings, which create a sense of height and spaciousness. Other options include tray ceilings, featuring a recessed center, and coffered ceilings, characterized by a grid of beams that add depth and elegance. Additionally, suspended ceilings, also known as drop ceilings, consist of tiles hung below the main structure, allowing for easy access to plumbing and electrical systems. Acoustic ceilings are designed to reduce noise, making them ideal for offices and schools. Each ceiling type serves different aesthetic and functional purposes.
