A glazing panel having beneficial anti-solar properties comprises a vitreous substrate carrying a tin/antimony oxide coating layer containing tin and antimony in a Sb/Sn molar ratio of from 0.01 to 0.14. In one application the coated substrate has a solar factor FS of less than 70% and the panel is formed by chemical vapor deposition from a reactant mixture comprising a source of tin and a source of antimony. In another application it is particularly suitable for use in vehicle glazing, in particular in vehicle roof windows, and the coated substrate has a spray-formed pyrolytic tin/antimony oxide coating having a thickness of at least 400 nm and, whereby the coated substrate has a luminous transmittance (TL) of less than 35% and a selectivity (TL/TE) of at least 1.3.

Glazing panel having solar screening properties

A transparent coated substrate with high reflectance, especially for use as in exterior glazing panels for buildings, is provided by a substrate carrying a coating stack comprising a pyrolytically-formed main layer containing oxides of tin and antimony, in which the main layer has a geometric thickness of at least 250 nm and the stack includes an outer reflective layer having a geometric thickness in the range 30 to 150 nm and a refractive index in the range 2.0 to 2.8, whereby the so-coated substrate has a reflectance (RL) of more than 10%.

Coated substrate with high reflectance

A method of manufacturing a glazing panel having a solar factor (FS) of less than 70% and being composed of a vitreous substrate and a tin/antimony oxide coating layer provided on the vitreous substrate and having a Sb/Sn molar ratio ranging from 0.01 to 0.5, preferable 0.03 to 0.5, the method including the steps of providing reactants in gaseous phase which comprise tin and antimony compounds, which are present in an amount effective to form the tin/antimony oxide coating layer; and forming the tin/antimony oxide coating layer pyrolytically on the vitreous substrate from the reactants in gaseous phase to provide the glazing panel having a solar factor (FS) of less than 70%.

Method of manufacturing a glazing panel

The invention concerns glass panels comprising thin layers in particular for providing them with solar protective or low-emissive properties, and also comprising other thin layers for correcting rainbow effects induced by the former. The invention is characterized in that said glass panels comprise a glass substrate coated with an aluminum oxynitride layer, deposited by gas phase pyrolysis, and whereof the characteristics of thickness and refractive index are selected so as to attenuate colors reflected by the layer providing the glass panel with low-emissive and/or solar protective properties, layer which is deposited on the aluminum oxynitride layer.

Pyrolytic layer of aluminium oxynitride and glazing comprising same

A solar control coated substrate with high reflectance (RL) and comprises a pyrolytically-formed coating layer containing oxides of tin and antimony in a Sb/Sn molar ratio of from 0.03 to 0.16, characterized in that the coating layer further contains additives comprising at least one element selected form the group consisting of aluminum, chromium, cobalt, iron, manganese, magnesium, nickel, vanadium, zinc, and zirconium and is free from fluorine, whereby the so coated substrate has a reflectance of at least 10%. The invention covers a process for making such a coated substrate and a glazing panel incorporating such a coated substrate.

Solar control coated substrate with high reflectance

A glazing panel having a solar factor (FS) of less than 70% includes a sheet of glass; and at least two coating layers provided on the sheet of glass including first and second coating layers, the first coating layer being composed of tin and antimony oxides and having a Sb/Sn molar ratio ranging from 0.01 to 0.5 and being one of (A) pyrolytically formed from reactants in a gaseous phase or (B) pyrolytically spray formed, and the second coating layer being composed of tin oxide doped with fluorine.

A glazing panel produced by pyrolytic coating of a substrate is described. One absorbent coating layer comprises at least one metal oxide selected from the oxides of chromium, cobalt and iron. A non-absorbent coating layer, in contact with absorbent layer comprises a material having a refractive index n(.lambda.) within the range 1.4 to 3.0. The glazing panel exhibits a color purity of greater than 16%, as measured by reflection from the coated side; and a solar factor of less than 70%.
