Abrégé
(EN)
The invention relates to glazing comprising at least one transparent substrate, such as glass, which is provided with stacked thin layers. The aforementioned stacked layers comprise, from the substrate upwards, at least: (a) one first dielectric layer comprising a layer forming a barrier to the diffusion of oxygen, which is selected from among silicon nitrides; (b) a lower stabilising metal layer which is made from a metal or alloy X; (c) a functional layer with reflecting properties in infrared and/or solar radiation, in particular a metal layer; (d) an upper blocking metal layer which is made from a metal or alloy Y; (e) a second dielectric layer comprising a layer forming a barrier to the diffusion of oxygen, which is selected from among silicon nitrides; and (f) optionally a protective oxide layer. According to the invention, the metal or alloy X of the lower stabilising layer is different from the metal or alloy Y of the upper blocking layer.

L'invention concerne un vitrage comprenant au moins un substrat transparent, notamment en verre, muni d'un empilement de couches minces comportant, dans cet ordre à partir du substrat, au moins (a) une première couche diélectrique comportant une ouche barrière à la diffusion de l'oxygène choisie parmi les nitrures de silicium, (b) une couche métallique inférieure stabilisatrice faite d' n métal ou alliage X, (c) une couche fonctionnelle à propriétés de réflexion cans l'infrarouge et/ou dans le rayonnement solaire, notamment métallique, (d) une couche métallique supérieure de blocage faite d'Ln métal ou alliage Y, (e) une deuxième couche diélectrique comportant une couche barrière à la diffusion de l'oxygène choisie parmi les nitrures silicium, et (f) éventuellement une couche protectrice d'oxyde, empilement dans lequel le métal ou alliage X de la couche inférieure stabilisatrice est différent du métal ou alliage Y de la couche supérieure de blocage.
