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.
Tegular: A functional edge detail. Tegular suspended ceiling panels have a rabbeted/reveal edge design that allows them to extend below the supporting grid, making the grid less conspicuous. Tile: Acoustical ceiling board, usually 12 x 12, which is stapled, cemented, or suspended by a concealed grid system. Edges are often kerfed and cut back.
