Four Types of Ceiling Tiles. There are four broad types of ceiling tiles - acoustical, plastic, tin and cork. Within those categories there is a further break down of tiles by design, installation and use. Acoustical ceiling tiles are used to help soundproof a room.
The type of ceiling tile can affect your cost. A basic white acoustic tile with pebbling will be on the lower end of the scale. This will most likely be a simple mineral fiber with minimal fire spread ratings. However, there are other types of tile.
