Title
(EN) TRANSPARENT SUBSTRATE WITH A MULTILAYER THIN FILM AND MULTIPLE GLAZING UNIT COMPRISING THE SAME
(FR) SUBSTRAT TRANSPARENT COMPORTANT UN FILM MINCE MULTICOUCHE ET VITRAGE MULTIPLE LE COMPRENANT
Abstract
(EN)
There is provided a transparent substrate provided with a multilayer thin film, including: a transparent substrate; a first stack positioned on the transparent substrate and including at least one dielectric layer; a first metallic functional layer positioned on the first stack and having an infrared reflective property; a second stack positioned on the first metallic functional layer and including at least one dielectric layer; a visible light absorbing layer positioned on the second stack; a third stack positioned on the visible light absorbing layer and including at least one dielectric layer; a second metallic functional layer positioned on the third stack; and a fourth stack positioned on the second metallic functional layer and including at least one dielectric layer. A ratio of a thickness of the third stack to a thickness of the second stack is 2.5 or more.

L'invention concerne un substrat transparent pourvu d'un film mince multicouche, comprenant : un substrat transparent ; un premier empilement positionné sur le substrat transparent et comprenant au moins une couche diélectrique ; une première couche fonctionnelle métallique positionnée sur le premier empilement et présentant la propriété de réfléchir les infrarouges ; un deuxième empilement positionné sur la première couche fonctionnelle métallique et comprenant au moins une couche diélectrique ; une couche absorbant la lumière visible positionnée sur le deuxième empilement ; un troisième empilement positionné sur la couche absorbant la lumière visible et comprenant au moins une couche diélectrique ; une deuxième couche fonctionnelle métallique positionnée sur le troisième empilement ; et un quatrième empilement positionné sur la deuxième couche fonctionnelle métallique et comprenant au moins une couche diélectrique. Le rapport entre l'épaisseur du troisième empilement et l'épaisseur du deuxième empilement est égal ou supérieur à 2,5.
