This invention provides glazing comprising a transparent substrate (1), for example glass, with a functional transparent conductive and/or low emissive layer (3) comprised of one or more metal oxides, an inner coating (2) with a geometric thickness ranging from 70 nm to 135 nm and a refractive index ranging from 1.65 to 1.90 disposed between the functional layer (3) and the substrate (1), and an outer coating (4) with a geometric thickness ranging from 70 nm to 110 nm and a refractive index ranging from 1.40 to 1.70, disposed on the functional layer (3).
L'invention concerne un vitrage comprenant un substrat (1) transparent, notamment en verre muni d'une couche (3) fondtionnelle transparent, conductrice et/ou basse émissive à base d'oxyde(s) métallique(s), d'un revêtement "interne" (2) d'épaisseur géométrique comprise entre 70 nm et 135 nm et d'indice de réfraction compris entre 1,65 et 1,90 qui se trouve disposé entre la couche fonctionelle (3) et le substrat (1) et d'un revêtement "externe" (4) d'épaisseur géométrique comprise entre 70 et 110 nm et d'indice de réaction compris entre 1,40 et 1,70 qui se trouve disposé sur la couche fonctionelle (3).
