Abstract: The present invention relates to a process for the production of 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 application of a reaction mixture (R1) for the production of a rigid polyurethane foam onto the first outer layer, bringing the lower side of a vacuum insulation panel into contact with the unhardened reaction mixture (R1), application of a reaction mixture (R2) for the production of 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 unhardened reaction mixture (R2), and finally hardening of the two rigid polyurethane foam systems (R1) and (R2) to give the composite element. The present invention further relates to composite elements thus obtainable, and also to the use of a composite element of the invention or of a composite element obtainable by a process of the invention, as component for refrigeration equipment or as construction material.

Abstract: The present invention relates to a process for preparing an insulating element for a tank comprising the steps of covering at least two surfaces of a mold with a metal foil; introducing a foam forming composition in the mold; and allowing a foam to form between the metal foils. The present invention further relates to the insulating element as such, an insulating assembly for a tank comprising insulating elements which are designed to fit closely to the periphery of the tank, wherein the insulating element is obtained or obtainable according to the process of the present invention; and also the use of said insulating assembly to insulate a tank, a tank wagon or a container.
