finish ceiling. It is hung on wires from the structure above, some distance below the roof structure. It can hung level and flat.

As for girders, beams, joists, and slabs above, they can be of varying sizes.

Suspended ceilings can be produced of almost any materials. Among them the most widely used are gypsum, board, plaster, and various boards made of fibers. Each of these materials is supported on its own system of small steel framing members. The framing members, in their turn, are hung from the structures on heavy and strong steel wires.

Suspended plaster ceilings are rather popular in modern construc­tions of different kinds. Ceilings produced of fibrous materials are classi­fied as acoustical ceilings. Their most useful property is high absorption of sound energy. As to plaster of gypsum board ceilings, they are highly re­flective of sound energy.
