Abstract

A multipane insulating glass for appliances having an inner-chamber temperature which is lower than the ambient temperature, in particular for viewing doors of refrigerators and freezers comprises at least two panes which are of approximately equal size and are arranged at a distance from one another. The distance is maintained by a spacer which runs continuously around the vicinity of the edge. One of the two outer panes is provided with an electrically conductive, transparent coating on its side which faces towards the space between the panes. In this glass, the coating, which is applied to the entire surface, is deactivated in the peripheral area of the pane, containing the contact surface for the spacer. Also, a process for producing coated flat glass materials for such insulating glass materials, as described above.
