An infrared radiation reflecting transparent layer system on a transparent substrate and a method for producing same is provided. The infrared radiation reflecting layer system comprises an infrared radiation reflecting layer sequence which includes a selective function usually consisting of a noble metal, mostly silver, or an alloy thereof and having a good selective reflectivity in the infrared range. The layer sequence is supplemented by at least one transparent dielectric layer of an oxynitride of a metal, a semiconductor or a semiconductor alloy having a low to moderate refractive index arranged directly on the substrate or above the infrared radiation reflecting layer sequence.

Infrared reflecting layer system for transparent substrate

A layer system that filters sun and heat can be applied to glass by a vacuum coating process. The system comprises at least one series of metal layers in addition to a respective series of lower dielectric layers and a respective series of upper dielectric layers. At least one series of metal layers and one series of upper and lower dielectric layers are configured as a sandwich system, wherein one metal layer is encapsulated by an upper and a lower intermediate layer consisting of hypostoichiometrically nitrided or oxidized metal of the metal layer and sandwich systems of the series of layers contain individual sandwich layers of a stoichiometric and hypostoichiometric oxide or nitride of a metal or semiconductor. An oxygen or nitrogen deficit of the sandwich layers increases towards a neighboring sandwich system and the oxide and nitride layers are produced in a vacuum coating process.
