Abstract

The heat insulation wall is a sandwich formed by two outer, at least substantially vacuum-tight, spaced-apart surface layers and a thermal insulation in between. The outer surface layers are connected to one another in vacuum-tight fashion by a connecting profile that extends along their contour. The connecting profile has an essentially U-shaped cross section and it is composed of a plurality of profile sections. The connecting profile and the surface layers together enclosing an evacuable space that is filled with the evacuable thermal insulation material. The profile sections of the connecting profile include corner sections which enclose the corners of the heat insulation wall in one-piece form.
