METHOD FOR MANUFACTURING VACUUM INSULATION PANELS
The invention relates to a method for manufacturing vacuum insulation panels (1) with a fiber core (3), comprising the steps of: providing a core blank of fibers, arranging foil sections on large faces of the core blank, compressing the core blank to a predetermined thickness for forming the core (3), wherein in the compression step the core blank is arranged between the foil sections, wherein the mechanical compression of the core (3) is maintained until the foil sleeve (2) is sealed, and wherein the compression step is performed at the place of manufacture at room temperature without thermal impact, connecting the foil sections for forming the foil sleeve (2), wherein a partial section of the foil sleeve (2) still remains open, evacuating the foil sleeve (2) enveloping the core (3) up to a pressure of <1 mbar, and complete closing of the foil sleeve (2), wherein the foil sleeve (2) is made of a plastic composite foil. This method distinguishes itself by the fact that the mechanical compression is carried out at a pressure of greater than 1 bar. Thereby a vacuum insulation panel (1) is obtained which can be manufactured with low expenditure and without the insulation effect suffering therefrom.
