Abstract
The invention relates to a method for producing a diffusing sheet of cork for an isothermic container, characterised in that a starting sheet of cork with an initial density is compressed so as to laterally increase the density, and to form hardened outer skins with a higher level of diffusion compared to the initial level, and thereby control the diffusion of the compressed sheet.
