Waermedaemmendes Schichtsystem fuer transparente Substrate

Heat insulating layer system for transparent substrate consists of one or more metallic reflection layers applied on a dielectric base layer on the substrate, a metallic blocking layer applied on the reflection layer or additionally below it, and an intermediate layer on the blocking layer. The novelty is that the intermediate layer is 5 nm thick and is a metal oxide, nitride, or oxynitride. A dielectric covering layer of oxide, nitride, or oxynitride of a further metal other than of that of the blocking layer. The layer composite made of intermediate layer and covering layer is applied once on the blocking layer. USE - For glass of buildings and vehicles. ADVANTAGE - The layer system has high transmission in the visible region and high reflection in the I.R. region.
