Method for producing a vacuum insulating body/vacuum insulation panel/VIP with the following method steps: a) A vacuum-tight film or film connection is provided. b) A flat filter material that is permeable to air but not permeable to a powder-like filling material is provided. c) The flat filter material is firmly connected to the vacuum-tight film or film connection at the edges in such a way that the connecting edge between the flat filter material and the vacuum-tight film or film connection is in any case not permeable to the powder-like filling material. d) The vacuum-tight film or film connection on the one hand and the flat filter material on the other hand are arranged in such a way that a receiving space that can be filled with filling material and is closed off with respect to the outside is obtained in between. e) The flat filter material is passed through by means of a filling element of a filling device for the powder-like filling material. f) With high ambient pressure, in particular therefore under normal atmospheric pressure, a desired amount of powder-like filling material is filled into the receiving space through the filling element, preferably under a filling pressure that is higher than the ambient pressure. g) After completion of the filling of the receiving space, the filling element is removed from the flat filter material and the flat filter material is closed again at the location concerned. h) The composite comprising the vacuum-tight film or film connection and the flat filter material and also the filling material located in the receiving space as a whole is brought to a pressure that is considerably lower than the ambient pressure in method step f) (vacuum) and the receiving space and the powder-like filling material located therein are thereby vented through the flat filter material, i) With a sustained vacuum, the vacuum-tight film or film connection is firmly sealed completely around the edges in such a way that this connecting edge is not permeable to air, and thus the receiving space as a whole is sealed in an air-tight manner. a) A vacuum-tight film or film connection is provided. b) A flat filter material that is permeable to air but not permeable to a powder-like filling material is provided. c) The flat filter material is firmly connected to the vacuum-tight film or film connection at the edges in such a way that the connecting edge between the flat filter material and the vacuum-tight film or film connection is in any case not permeable to the powder-like filling material. d) The vacuum-tight film or film connection on the one hand and the flat filter material on the other hand are arranged in such a way that a receiving space that can be filled with filling material and is closed off with respect to the outside is obtained in between. e) The flat filter material is passed through by means of a filling element of a filling device for the powder-like filling material. f) With high ambient pressure, in particular therefore under normal atmospheric pressure, a desired amount of powder-like filling material is filled into the receiving space through the filling element, preferably under a filling pressure that is higher than the ambient pressure. g) After completion of the filling of the receiving space, the filling element is removed from the flat filter material and the flat filter material is closed again at the location concerned. h) The composite comprising the vacuum-tight film or film connection and the flat filter material and also the filling material located in the receiving space as a whole is brought to a pressure that is considerably lower than the ambient pressure in method step f) (vacuum) and the receiving space and the powder-like filling material located therein are thereby vented through the flat filter material, i) With a sustained vacuum, the vacuum-tight film or film connection is firmly sealed completely around the edges in such a way that this connecting edge is not permeable to air, and thus the receiving space as a whole is sealed in an air-tight manner.
