Embodiment Construction

[0035] For the sake of clarity, figure 1 The glass in is presented in section without respecting the proportions of the different components. The glass sheet 1 is covered with a set of layers comprising a layer 4 based on infrared-reflecting silver. This silver layer is arranged between two sets of dielectric layers which protect it and give it good light transmission with good reflection neutrality.

[0036] The silver layer 4 is advantageously deposited on the layer 3 based on zinc oxide. Layers of zinc oxide and layers based on doped zinc oxide are known to contribute to the formation of a good interface with the silver layer without being rough. They improve the performance of the latter overall. For the same amount of silver per unit area, the conduction and thus emissivity of the layers is improved when they are deposited in this way. Only small thicknesses of zinc oxide may be involved, the thickness being no greater than 15 nm.

[0037] When the thickness of the z...

Abstract

The invention relates to an essentially transparent glazing including an assembly of thin layers deposited in a vacuum with a magnetron, and having sun-proof and / or low-emission properties, wherein the surface protection layer comprises a layer containing titanium oxide and at least one other high-hardness metal oxide selected from the group including ZrO2, SiO2, Cr2O3. The glazing of the present invention is capable of withstanding a thermal treatment at 550 DEG C for 5 minutes without generating optical defects such as discolouring or iridescence. These glazings are hardenable.

Description

technical field [0001] The present invention relates to vitrages comprising a set of thin layers imparting solar protection or low emissivity properties and capable of withstanding bending / tempering type heat treatments. Background technique [0002] The coating most commonly used for the glasses in question is achieved by magnetron-assisted deposition techniques (so-called "magnetron sputtering") under vacuum. [0003] Layer systems deposited in this way make it possible to achieve excellent properties both thermally and optically. They can in particular be very selective, in other words constitute a strong filter for infrared rays, while allowing visible wavelengths to pass. In the best case, they provide ideal reflection neutrality, thereby avoiding, inter alia, undesired coloration. [0004] In addition to the properties sought, the glasses in question should also have sufficient resistance to the various attacks to which they may be subjected. This concerns in partic...
