A transparent, heat-insulating coating, neutrally acting in transparency and external appearance, for transparent substrates, more particularly for insulating glass panes, is disclosed. The coating is formed from a bismuth oxide-silver-bismuth oxide multilayer system in which a more electronegative substance, i.e. a substance with a higher normal potential, is added to the bismuth oxide layers to avoid blackening under UV radiation. If manganese is used as the electronegative substance, its oxidation to higher valency states can be prevented by the addition of trivalent substances. The layers may be applied in a conventional way by diode-cathode atomization.
