Coffered ceiling
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.
Coffered ceilings can be found in columned halls of antiquity and later mainly in buildings from the Renaissance and Baroque periods .
