The invention relates to a method for producing a vacuum insulation panel (12), wherein a film (5) is inserted into a cavity (7) of a molding tool (6) and an open-cell PUR mixture is applied. Protruding regions of the film are folded and the PUR mixture is completely surrounded by film. The molding tool closes, the PUR mixture foams and presses the film against the walls of the cavity. This results in the formation of an open-cell rigid PUR foam structure with a compact skin which is surrounded by film. A step of evacuating the open-cell (rigid) PUR foam structure creates a vacuum insulation panel. In order to improve the process integration and for efficient production of vacuum insulation panels, all the steps of the method can be carried out directly one after another.
