Foil-wrapped vacuum insulation element

A foil-wrapped vacuum insulation panel having a core, and an air-tight envelope in the form of a wrapping foil surrounding the core made of powder or granulate, wherein between the core made of a loose powder or a loose granulate and the air-tight wrapping foil, there is provided at least one intermediate layer of cardboard and/or paperboard, which completely envelopes, in a powder-tight manner, the core made of powder or granulate and which intermediate layer of cardboard and/or paperboard is formed as a cuboid box which has approximately the same shape as the finished vacuum insulation panel and comprises a body with a filling opening which is closed by a lid, wherein the loose powder or the loose granulate is filled into the cuboid box in such an amount that the body of the cuboid box is completely filled up to its very top, and the shape of the vacuum insulation panel is acquired only via the cuboid box and not by the powder or granulate, while the structural integrity of the core is not sufficient to retain the shape of the core on its own without the surrounding cardboard or paperboard box, because the loose powder or the loose granulate of the core is filled into the cardboard and/or paperboard cuboid box in the powdered state, without active mechanical pressing, wherein the loose powder or the loose granulate is made of pyrogenic silica, and the core has a density between 140 kg/m3 and 160 kg/m3.
