Abstract:
A vacuum insulated panel comprises a filler and a vacuum-tight high-barrier film envelope, with an air-permeable sheet element that serves as a filter material for dust, wherein the sheet element consists of the same material as the sealing layer of the high-barrier film enveloping the vacuum insulated panel and passes through the sealing seams of the high-barrier film, and to a method for producing such a vacuum insulated panel, wherein the sheet element, in the form of a strip preferably folded along a central axis, is placed between two sealing films and is thermally adhesively bonded to the inwardly disposed sealing layers of the sealing films such that a joint is formed between the two sealing films which are sealed together by means of a respective seam on each of perpendicular sides, the strip-shaped sheet element being co-sealed into the seams.
