A method of forced diffusion treatment for a thermally insulating part (40) made from expanded synthetic foam, comprising: during a discharge step, heating the insulating part to a discharge temperature higher than ambient temperature and simultaneously exposing the insulating part to a gaseous atmosphere having low partial pressures of dinitrogen, dioxygen, carbon dioxide and the gases having a diffusion coefficient in the expanded synthetic foam greater than or equal to that of the dinitrogen, ending the discharge step when the cumulative partial pressures of the dinitrogen, dioxygen, carbon dioxide and gases having a diffusion coefficient in the expanded synthetic foam greater than or equal to that of the dinitrogen in the insulating part is less than a predefined threshold.
