Abstract

A thermally insulating coating system for curved and/or hardened glass panes includes at least one layer of noble metal enclosed by a lower and an upper blocker layer. An underoxidic NiCrO.sub.x layer with a thickness between one .ANG. and two nm is embedded into the noble-metal layer. The advantage is that the optical qualities of the coating system are not influenced by the tempering and curving of the glass pane.
