Abstract: front page image
(EN)The invention relates to an insulating double glazing comprising a sheet of glass which has on the face (2) an assembly of layers known as low-emissivity layers, produced by sputtering and comprising at least one infrared-reflecting metallic layer, the other glass sheet comprising on the face (4) one or more metal oxide layers deposited by gas pyrolysis, the space located between the sheets being sealed and filled with insulating gas composed of krypton for at least 86% by volume and at most 5% of air, this glazing having a light transmission which is no less than 60% (for thicknesses of the clear glass sheets of 4 mm).
(FR)L'invention concerne un vitrage double isolant comprenant une feuille de verre qui présente sur la face (2) un ensemble de couches dites basse-émissives, produites par pulvérisation cathodique et comprenant au moins une couche métallique réfléchissant les infrarouges, l'autre feuille de verre comportant sur la face (4) une ou plusieurs couches d'oxydes métalliques déposées par pyrolyse gazeuse, l'espace situé entre les feuilles étant clos et rempli de gaz isolant composé de krypton pour au moins 86% en volume et au plus 5% d'air, ce vitrage présentant une transmission lumineuse qui n'est pas inférieure à 60% (pour des épaisseurs des feuilles de verre clair de 4mm).
