ABSTRACT OF THE DISCLOSURE 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 sputtering 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.
