Claim:
An automotive vehicle having an exterior surface, a passenger compartment and comprising a plurality of body parts, wherein two of said body parts are a roof and a door and each of said roof and said door having a longitudinal dimension that will extend in the direction of the length of the vehicle and a transverse dimension perpendicular to the longitudinal dimension and parallel to the exterior surface, and each of said roof and said door comprising: an outer sheet having an outer surface that will form a part of the vehicle exterior surface; an inner part disposed between said outer sheet and the passenger compartment when each of said roof and said door is assembled to the vehicle, said inner part having a surface that faces said outer sheet; a first infrared radiation reflecting layer on said outer surface of said outer sheet; and a second infrared radiation reflecting layer on said surface of said inner part, wherein: said inner part comprises a body of thermal insulation material; said outer sheet and said inner part delimit an air flow path for supporting a flow of cooling air adjacent said outer sheet and in the direction of said longitudinal dimension, said air flow path extending, or being distributed, over said transverse dimension for transporting heat convectively away from the vehicle; said air flow path having an air inlet and an air outlet, both communicating with air outside the vehicle when said roof and said door are assembled to the vehicle; and said air flow path is permanently isolated by said inner part from the passenger compartment.
