Mouldings suitable for building refrigerators have an inner and an outer covering layer, as well as an intermediate core which consists to a large extent of an open-pore polyurethane hard foam. The covering layers are pressed by the outer atmospheric pressure against the hard foam core but do not adhere to the core. Also disclosed are a process for manufacturing these mouldings and refrigerators which contain at least one of said mouldings.

Ces éléments moulés utiles comme éléments constitutifs de réfrigérateurs comprennent une couche extérieure et une couche intérieure de revêtement, ainsi qu'un noyau intermédiaire constitué dans une large mesure d'une mousse dure de polyuréthanne à pores ouverts. Les couches de revêtement sont comprimées contre le noyau en mousse dure par la pression atmosphérique extérieure et n'adhèrent pas au noyau. L'invention concerne également un procédé de fabrication de ces éléments moulés, ainsi que des réfrigérateurs qui contiennent au moins un des éléments moulés décrits.
