Abstract

A glass pane is provided with a multilayer system having metallic reflection and a high thermal resistance. The multilayer system comprises a dielectric base layer, a metal layer having a high reflection, made of chromium or a metal alloy containing at least 45 wt % chromium, and a nitride top layer. The dielectric base layer is composed of at least one oxide partial layer made of SnO2, ZnO and/or TiO2, close to the surface of the glass, and a nitride partial layer, close to the metal layer.
