A glass article with a solar-control function includes at least one glass substrate and a stack of layers deposited on at least one face of the substrate. The stack of layers includes a layer of titanium oxynitride of general formula TiNO, in which 1.00&#x3c;x&#x3c;1.20 and in which 0.01&#x3c;y&#x3c;0.10. The stack of layers further includes layers of dielectric materials and optionally of metallic or nitrided layers based on chromium, nickel, titanium, niobium or a mixture of at least two of these elements.

Glazing with solar protection properties comprising a titanium oxynitride layer

A glass article includes at least one glass substrate on which a stack of layers is deposited. The stack includes at least one layer consisting of a layer of silicon nitride of formulation SiN, in which x is less than 1.25. The physical thickness of the SiNlayer is between 5 and 50 nm. The light reflection of the glass article, measured on the side of the substrate on which the stack is deposited, is greater than 20%.

Reflective glazing comprising a thin layer of silicon-rich silicon nitride

A material includes a transparent substrate coated with a stack of thin layers successively including, starting from the substrate, an alternation of three silver-based functional metallic layers and of four dielectric coatings, so that each functional metallic layer is positioned between two dielectric coatings. The thicknesses of the three functional layers and the thicknesses of the dielectric coatings are selected in order to give the materials solar factor values of less than 20% for a light transmission of the order of 40%.
