Abstract:
1. A heat insulated wall product made by a process comprising: providing a connecting profile, an evacuable heat insulating material, two outer covering layers each having a pass-through aperture, and a tube section including a hollow bore and two end sections with at least one of the two end sections having a circumferentially positioned flange-shaped expanded and flattened region; connecting the two outer covering layers to the connecting profile with a vacuum-tight seal and with a disposition of the two outer covering layers at a spacing from one another with their pass-through apertures generally aligned with one another, the two outer covering layers together with the connecting profile delimiting an intermediate space; disposing the tube section relative to the two outer covering layers with the pass-through aperture of each outer covering layer being in communication with the hollow bore of the tube section and with the at least one flange-shaped expanded and flattened region in facing relation to an interior surface of a selected one of the two outer covering layers that faces toward the other outer covering layer; connecting in a sealed manner the selected one outer covering layer to the flange-shaped expanded and flattened region of the tube section; disposing the evacuable heat insulating material in the intermediate space delimited by the two outer covering layers and the connecting profile; and disposing the intermediate space delimited by the two outer covering layers and the connecting profile in an evacuated condition.
