Solar controlled glazing and method of producing glazing
First Claim
1. A method of producing glazing having a transmission of between 5 and 40% in the visual spectrum range and heat-reflection properties, comprising the steps of applying at least first and second coating layers to a transparent substrate by cathode sputtering, said first layer comprising an oxide layer having an optical thickness of between 20 and 280 nm and applied by cathode sputtering directly to the substrate in an oxygen-containing atmosphere, and said second layer comprising a chromium nitride layer having a geometric thickness of between 10 and 40 nm applied by cathode sputtering in an atmosphere consisting of an inert gas and nitrogen.

Abstract
Solar-controlled glazing having a transmission of between 5 and 40% in the visible spectrum range and having heat-reflection properties is produced by applying an oxide layer having an optical thickness of between 20 and 280 nm directly to a transparent substrate by cathodic evaporation in an oxygen-containing atmosphere to form a first layer. A chromium nitride layer having a geometric thickness of between 10 and 40 nm is then applied in an atmosphere consisting of inert gas and nitrogen to provide a second layer. An optical third dielectric layer may be applied to the second layer. The oxide layer is selected from oxides of tin, titanium and aluminium.
