Abstract
The invention relates to an insulating double glazing comprising a sheet of glass which has on the face () 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 () 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), wherein said metal oxide layers comprising a doped tin oxide layer having haze of less than 0.3%, Rof less than 10 nm, and thickness of not less than 200 nm.
