A cassette ceiling (also field ceiling ) has box-shaped recesses (cassettes) on its underside in a regular arrangement. Such a ceiling is formed by intersecting ribs or beams . The preferred materials are traditionally wood , stone or stucco . But there are also coffered ceilings imitated by illusionistic painting ( trompe-l'œil ).
Cassette ceilings were originally created by applying the rather thin and flat filling of the fields to the top of the thick, high beams. A hanging fixation was more difficult, and the recesses brought technical advantages (acoustics) and an optical structure of the ceiling. The construction of the ceiling could be load-bearing, as in the Pantheon, where this construction was also advantageous for weight reasons. Heavy wooden coffered ceilings e.g. B. were non-load-bearing components that were attached to the ceiling or roof structure. With greater distances (great room depths), the weight of these ceilings then had to be borne by reinforced roof structures.
Examples of coffered ceilings:
- Pantheon (Rome)
- Diocletian's Palace , Split
- Jever Castle
- Leiben Castle , Lower Austria
- Hospital church in the courtyard
- Golden Hall in Augsburg
- The cedar hall in the Fugger Castle in Kirchheim / Swabia
- Palacio de los Zúñiga y Avellaneda in Peñaranda de Duero , Spain
- Santa Maria Maggiore Basilica , Rome
- Basilica of San Paolo Fuori le Mura , Rome
- Pisa Cathedral
- Church of St. Martin in Zillis .
- Parish church of St. Regina in Drensteinfurt
- Heihsgut , Lungau Salzburg
- Hoflößnitz mountain and pleasure house

A type of suspended ceiling is now also referred to as a coffered ceiling in which square panels (coffers) made of wood (materials) , mineral (fiber) boards , plasterboard or gypsum fiber boards are inserted into a suspended support system made of metal . These ceilings are inexpensive and easy to dismantle (for maintenance work in the space). Mostly they are also acoustic ceilings .
