Product glass substrate provided with a low emissivity layer.

摘要

The invention relates to a glass substrate by a functional transparent conductive, low emissivity BASED OXIDE LAYER (S) METALICO (S) ON WHICH DEPOSITS an "external" coating with a thickness OPTICO IS APPROXIMATELY ONE PART FOUR OF WAVELENGTH MIDDLE COUNTRY BELONGS TO THE VISIBLE, and preferably centered on 550 nm. It is also expected an "internal" liner between functional layer and the substrate, said coating having AN OPTICAL THICKNESS between 50 and 75 NM.
