Glazing provided with stacked thin layers reflecting infrared rays and/or solar radiation
First Claim
1. Glazing that comprises at least one transparent substrate S, especially made of glass, provided with a stack of thin layers comprising an alternation of n functional layers A having reflection properties in the infrared and/or in solar radiation, especially metal layers, and of (n+1) coatings B, where n≧
- 1, said coatings B comprising a layer or a superposition of layers made of a dielectric, so that each functional layer A is placed between two coatings B, wherein at least one of the functional layers A is (i) directly in contact with the dielectric coating B placed on top of it and (ii) in contact with the dielectric coating B placed beneath it via a layer C that absorbs at least in the visible, of the metallic, optionally nitride, type.

Abstract
The invention relates to glazing that comprises at least one transparent substrate S provided with a stack of thin layers comprising an alternation of n functional layers A having reflection properties in the infrared and/or in solar radiation, especially metal layers, and (n+1) coatings B made of a dielectric, where n≧1. The stack satisfies the following criteria: at least one functional layer A is (i) directly in contact with the dielectric coating B placed on top of it and (ii) in contact with the dielectric B placed beneath it via a layer C that absorbs at least in the visible, of the metallic, optionally nitride, type.
