TRANSPARENT SUBSTRATE WHICH IS COVERED WITH A STACK OF THIN LAYERS HAVING REFLECTION PROPERTIES IN INFRARED AND/OR SOLAR RADIATION

摘要

The invention relates to a transparent substrate which is provided with a stack of thin layers comprising: at least one functional metallic layer which is based, for example, on silver, and which has reflection properties in infrared and/or in solar radiation; at least one metallic blocking layer which is in contact with the functional layer; and at least one upper dielectric layer. The invention is characterised in that at least one blocking layer is based on zirconium, and in that the upper dielectric layer comprises at least one ZnO-based layer which is in contact with either the functional layer or the blocking layer.
