Deposition of pyrolyzed layers with improved performance and a glass pane coated with such a layer.

摘要

Deposition of pyrolysed layers with improved performance. The invention provides a glass substrate (5) coated with such layers, with properties imparted by these layers, especially low emissivity, which are equivalent to those of thicker layers manufactured under the usual conditions. For this purpose a process is provided for manufacturing these particular layers, consisting in providing, before the deposition of the pyrolysed layer, a stage of superheating (10) without homogenisation of temperature within the thickness of the substrate. Application to the manufacture of glazing for motor vehicles and the building industry in particular. <IMAGE>
