Abstract

Method for making glazing with a high transmissivity in the visible spectral range and with a high reflectivity for thermal radiation as well as low surface resistance. On substrates of mineral glass a system of coatings is built up in the following order: PA1 Coating 1: oxide from the group, tin oxide, silicon dioxide, aluminum oxide, tantalum oxide, zirconium oxide, or mixtures thereof, PA1 Coating 2: alloy of 80 weight-percent of nickel and 20 weight-percent of chromium, PA1 Coating 3: silver or a silver alloy with at least 50 weight-percent silver content, PA1 Coating 4: alloy of 80 weight-percent of nickel and 20 weight-percent of chromium, PA1 Coating 5: oxide from the group tin oxide, silicon dioxide, aluminum oxide, tantalum oxide, zirconium oxide, or mixtures thereof. Thereafter the substrate with the entire packet of coatings is heated to the softening temperature of the glass and bent to the final shape.
