Roof conversion with a substructure made of drywall metal profiles (CD profiles) and a room-side planking made of plasterboard, which is applied in one or more layers. The level of the substructure can also serve as an installation level, e.g. for electrical connection cables. In addition, the substructure can also compensate for flatness tolerances of the substrate (e.g. the rafters).
