{{main|Ceiling tile}}
Ceiling tiles are lightweight tiles used inside buildings. They are placed in an aluminium grid; they provide little thermal insulation but are generally designed either to improve the acoustics of a room or to reduce the volume of air being heated or cooled.

Mineral fiber tiles are fabricated from a range of products; wet felt tiles can be manufactured from perlite, mineral wool, and fibers from recycled paper; stone wool tiles are created by combining molten stone and binders which is then spun to create the tile; gypsum tiles are based on the soft mineral and then finished with vinyl, paper or a decorative face.{{Citation needed|date=March 2015}}

Ceiling tiles very often have patterns on the front face; these are there in most circumstances to aid with the tiles ability to improve acoustics.{{Citation needed|date=March 2015}}

Ceiling tiles also provide a barrier to the spread of smoke and fire. Breaking, displacing, or removing ceiling tiles enables hot gases and smoke from a fire to rise and accumulate above detectors and sprinklers. Doing so delays their activation, enabling fires to grow more rapidly.<ref>[https://purl.fdlp.gov/GPO/gpo16742 Missing Ceiling Tiles.] {{Webarchive|url=https://web.archive.org/web/20210416003903/https://permanent.fdlp.gov/gpo16742/fastfacts_ceilingtiles.pdf |date=16 April 2021 }} Washington, D.C.: [[United States Congress Office of Compliance]], 2008.</ref>

Ceiling tiles, especially in old [[Mediterranean Basin|Mediterranean]] houses, were made of terracotta and were placed on top of the wooden ceiling beams and upon those were placed the roof tiles. They were then plastered or painted, but nowadays are usually left bare for decorative purposes.

Modern-day tile ceilings may be flush mounted (nail up or glue up) or installed as [[dropped ceiling]]s.
