Ceiling is part of the construction of a barrier layer between the frame of the building with a roof frame, so it can be as tall buildings or it can be said under the framework of the roof. Ceiling or often called the ceiling is an area on the inside of the building space (home).

Ceiling serves to provide an aesthetic appearance to the home or building. Ceiling can help hide the power plants, such as wires, lights, and roof structure so that the interior space look more beautiful. With the ceiling, the air temperature in the room could be more controllable. For example, the ceiling can reduce the temperature of the heat chamber roof arising from the sun shining on the roof. The hot air in the roof space were retained by the ceiling so it does not directly flow chamber underneath so that the room temperature is maintained. In the installation of air conditioning / air conditioner, ceiling indoor use can make the AC work becomes more efficient, because only the room below the ceiling that need to be 'cooled down' while a space between the roof and the ceiling is not necessary.
