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.
