Abstract
The invention relates to a load-bearing vehicle roof of so-called sandwich construction, wherein the material layer included in the vehicle roof comprises polymeric materials, laminate materials and/or metal layers. Furthermore, the invention relates to a method for manufacturing such a vehicle roof. The load-bearing vehicle roof according to the invention comprises an outer cover layer (1), a core (3) and an inner cover layer (4) which together form a load-bearing structure. The load-bearing vehicle roof according to the invention is characterized in that at least one insulating layer (5) and/or a decorative layer (6), intended to be visible from a passenger compartment within a motor vehicle, is/are provided inside the inner cover layer (4), and that the insulating and/or the decorative layers (6) are provided as layers of the load-bearing vehicle roof before mounting onto the motor vehicle. Accordingly, the load-bearing vehicle roof according to the invention comprises both the outer and inner roof before being mounted onto a vehicle body, for which reason no separate inner-roof has to be post-mounted. The invention has its main application within the field of ground-based motor vehicles, such as passenger cars of commercial vehicles.
