This installation is able to integrate projectors of various different types in the ceiling. The required space for the projector, wiring and ventilation is created by means of a formal articulation in the ceiling surface. The size of the opening in the ceiling articulation enables easy replacement of the individual pieces of equipment as its inclination is adapted to the projector cone. The ceiling elements are made of CNC-processed polystyrene, finished with a plaster and a dispersion coating.
