Abstract: The invention relates to a method for producing composite profiled elements comprising at least two metal shells which are connected by connecting pieces made of a thermoplastic material and comprising a core made of rigid polyurethane foam. The method has the steps of introducing the starting components of the rigid polyurethane foam into a cavity formed by the metal shells, wherein the rigid polyurethane foam is formed, and subsequently coating the outer surface of the composite profile using a powder coating or a baking enamel, said rigid polyurethane foam being obtained by reacting the following components: A) at least one polyisocyanate, B) at least one multifunctional compound which is reactive towards isocyanates, C) one or more propellants at least comprising formic acid, D) optionally one or more flame retardants, E) optionally one or more catalysts, and F) optionally other auxiliary agents or additives. The starting components of the rigid polyurethane foam do not contain inorganic fillers.
