A ceiling is part of a building that encloses a space and is exposed overhead. Ceilings help create enclosure of and separation between spaces, they help to control the diffusion of light and sound around a room, and help prevent the passage of sound between rooms. They have fire resistant properties and may also accommodate building services such as vents, lighting, sprinkler heads and so on, as well as being able to conceal other services such as ducts, pipes and wiring.
There are a number of ways of finishing a ceiling.
 Plasterboard and skim
- Can create a void for services.
- Good fire-resistance.
- Smooth seamless finish.
- The grid is convenient for housing lighting and other services.
- Good acoustic qualities.
- Variety of tiles available.
- Good for covering roof voids.
- Individual tiles can be easily replaced.
- Very hygienic and surfaces can be kept clean.
- No decoration required.
- It can be used as a suspended ceiling.
- Larger panels can start to sag.
- Not very good fire rating.
- Heat can cause damage; lighting installations need to be considered.

- Can be aesthetically pleasing.
- Sustainable material.
- Can have a low fire rating.
- Requires sealing and maintenance to prevent timber deterioration.
- Can be troublesome in high humidity areas like bathrooms and kitchens.
In some buildings, it is possible to omit a 'finished' ceiling completely and simply expose the structural and mechanical components of the building to the interior. This offers the advantages of economy and ease of access for maintenance, and can also expose the thermal mass of the building. The thermal mass of exposed ceilings can be further exploited by the installation of heating or cooling elements such as chilled beams.
