ABSTRACT:
A method for producing thermo-insulating elements wherein porous, powdery insulating material is thermally degassed and poured into an evacuated casing. Getter material is mixed with insulating material to form a mixture. The mixture is then thermally degassed. The degassed mixture is poured into an evacuated casing, which is then sealed. The getter material may comprise powdery or pellet-shaped molecular sieve, a zeolitic material, or a metal alloy. The method may be performed by degassing the mixture in a vacuum drier, and feeding the mixture in continuous vacuum into a permanently evacuated container.
