Abstract
The invention relates to a transparent glass substrate having a coating including, in order: a first reflected color neutralization layer; a low-emissivity second layer essentially made up of SnO2:F and having a thickness between 455 and 800 nm; and a third layer that is essentially made up of SiOx, x being less than or equal to 2, and has a thickness between 40 and 65 nm or between 140 and 180 nm. The invention also relates to a double glass sheet and a triple glass sheet, manufactured from such a glass substrate, and to a window comprising said glass sheets.
