Cassette door
The door leaf of a cartridge door , sectional door , frame door or door frame construction consists of a peripheral frame which may optionally also have internal transverse and longitudinal joints. The inner edges of the frame wood are often beveled or profiled and grooved in the middle to accommodate the so-called filling . The filling itself can also be profiled and decorated in various ways and is also known as a cassette .
The load-bearing frame is made up of at least two vertical bars and two horizontal wooden frames, which are traditionally connected and glued together using mortise-and-tenon or web-wedge connections .
Traditionally, the filling consists of glued boards that taper towards the edge so that they can be fitted into the groove in the timber frame. In the simplest case, a sheet of plywood can also serve as a filling. Fillings made of glass or other materials can also be used.
Panels glued together from boards must not be glued to the frame boards during assembly. They should be free to move around in moisture-induced expansion to avoid or shrinkage of wood cracking and warping. Glass fillings are only inserted after the frame has been completed and fastened with putty or nail strips .
Inexpensive cassette doors are no longer necessarily composed of a frame. In some cases, the cassettes are only hinted at by milling profile grooves in a continuous, solid laminated wood or plywood panel in order to give the impression of a handcrafted cassette door.
The time and place of manufacture can sometimes be deduced from the number, arrangement and profile of the cassettes for historic doors.
