    Abstract: The present invention relates to a method for producing composite elements comprising a first and a second outer layer, a vacuum insulation panel between the two outer layers, rigid polyurethane foam in contact with the first outer layer and the underside of the vacuum insulation panel and also rigid polyurethane foam in contact with the second outer layer and the upper side of the vacuum insulation panel, comprising applying a reaction mixture (R1) for producing a rigid polyurethane foam to the first outer layer, bringing the lower side of a vacuum insulation panel into contact with the uncured reaction mixture (R1), applying a reaction mixture (R2) for producing a rigid polyurethane foam to the upper side of the vacuum insulation panel, bringing the second outer layer into contact with the layer of the uncured reaction mixture (R2), and finally curing the two rigid polyurethane foam systems (R1) and (R2) to obtain the composite element. The present invention also relates to composite elements obtainable in such a way, and to the use of a composite element according to the invention or of a composite element obtainable by a method according to the invention as components for cooling devices or as building material.
