ABSTRACT:
Heat insulation is provided for a refrigerator or freezer. The insulation includes a closed cell material, which is placed in a hermetically closed space (13) surrounded by a diffusion-tight shell. The space communicates with a vacuum source, and a gas diffuses through the cells five times faster than air gasses. The material does not achieve its full insulating properties until the refrigerator has been used.
