A method for producing a body component in sandwich construction

A method for producing a body part, particularly a vehicle roof, in a sandwich construction with the following layer structure from the outside inwards: - an outer layer (1) in the form of a metal sheet or a plastic film, - an underlying support layer (2) of a foam material, - a lying under this insulating layer (3) of a further foam material with a lower density, and - an inner layer (4) as a wall covering of the vehicle interior, wherein the support layer (2) not to the inner layer (4) comes into contact; characterized, in that constructed, the individual layers (1, 2, 3, 4) one after the other in a lower tool (5) of a foaming mold starting with the in the lower tool (5) engaged outer layer (1) and through, followed by reaction of the two inner layers (2, 3) connected to each other become.
