Transparent substrate incorporating a stack of thin layers with reflective properties to infrared and/or solar radiation for glazing applications

摘要

A transparent substrate is provided with a stack of thin layers incorporating at least one functional metal layer, notably silver based, with reflection properties in the infrared and/or solar radiation range, at least one metal blocking layer in contact with the functional layer and at least one upper dielectric layer. At least one blocking layer has a zirconium base and the upper dielectric layer includes at least one layer with a base of zinc oxide in contact with the functional layer or the blocking layer. Independent claims are also included for: (a) low emissivity or anti-sun glazing and notably laminated or double glazing incorporating at least one such substrate; (b) a method for improving the mechanical strength of the transparent substrate provided with a stack of thin layers.
