A cassette is typically a flat case or cartridge that can be easily installed or removed. It is derived from the Old North French word ‘casse’, meaning box.

In the construction industry the word ‘cassette’ refers to components of building services systems such as chilled water cassettes, or to modular construction components such as facade cassette panels, floor cassettes, wall cassettes, roof cassettes and so on, which may include timber or metal frame, cladding, insulation and so on in a single unit. Typically cassettes are prefabricated in a factory setting and then installed quickly on site, reducing the need for working at height. They may also be removable without being damaged so they can be re-used.
