Patent ID: 11634264

Abstract:
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 powder or granulate and the air-tight wrapping foil, there is provided at least one intermediate layer of cardboard and/or paperboard, which completely envelopes the core made of powder or granulate in a powder-tight manner and is formed cuboid box which has approximately the same shape as the finished vacuum insulation element, wherein the powder or granulate is filled into the cuboid box in such an amount that the body is completely filled up to its very top, and the shape of the vacuum insulation element 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.
