Abstract
The invention relates to a method for manufacturing vacuum insulation panels with a fiber core, comprising the steps of: providing a core blank of fibers, compressing the core blank to a predetermined final thickness for forming the core, evacuating a foil sleeve enclosing the core up to a pressure of ≦1 mbar, and sealing the foil sleeve. The method according to the invention is characterized by the fact that, in the compression step, the core blank is arranged between two cover elements and is mechanically compressed therebetween, that the core is kept under compression pressure until the foil sleeve is sealed, and that the compression step is performed at the place of manufacture at room temperature without thermal impact. Thus, a method for manufacturing vacuum insulation panels with a fiber core can be improved such that it can be performed with reduced energy requirement and yet the insulating effect of the vacuum insulation panels does not suffer therefrom.
