Abstract:
1. A solar control glazing panel, having a solar factor (FS) of less than 70% and an emissivity of less than 0.4, comprising a soda-lime float glass substrate carrying a coating which comprises a plurality of coating layers: a first coating layer formed pyrolytically by chemical vapor deposition or by spray on the substrate, comprising tin and antimony oxides and having a Sb/Sn molar ratio ranging from 0.03 to 0.15, and a second coating layer positioned over the first coating layer and comprising tin oxide doped with fluorine, wherein the coating excluding the second coating layer is such as to confer on a 4 mm thick sheet of clear soda-lime glass a solar energy transmission (TE) measured according to the CIE standard ranging from 27 to 54.3%.
