HIGH-REFLECTION GLAZING

The invention relates to a glazing that comprises at least one layer deposited by cathodic spraying under vacuum, said layer containing one or more oxides and a proportion in weight of titanium oxide of at least 40% and not exceeding 95%. The thickness of the layer in question and optionally the thi...

Beschreibung
Zusammenfassung:	The invention relates to a glazing that comprises at least one layer deposited by cathodic spraying under vacuum, said layer containing one or more oxides and a proportion in weight of titanium oxide of at least 40% and not exceeding 95%. The thickness of the layer in question and optionally the thickness of the other layers containing metal oxide is/are selected so that on a clear "float" glass sheet having a thickness of 4 mm, said layer(s) would yield a reflection of at least 15% and a light transmission of at least 60%. The layer or layer system in question further has a mechanical and/or chemical resistance comparable to that of layers produced by pyrolysis for obtaining products having the same kind of optical properties.
