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.
Clay-based tiles have been used in and around homes for centuries. As various cultures developed techniques for producing tiles and technologies advanced, different types of clay tiles, each with its own characteristics, emerged. Included in this grouping are ceramic tiles and quarry tiles. Both are made-man from clay baked to high temperatures, but their similarity ends there.
