Abstract
The invention relates to triple glazing comprising at least one glass sheet that has a system of layers on one side which are produced using sputtering and include at least one metal layer that reflects infrared radiation. The at least one glass sheet has a set of low-emission layers on the other side, said set of layers comprising one or more oxide layers that are deposited using gas phase pyrolysis. The disclosed glazing has a minimum light transmittance of 60 percent (standard EN 410, illuminant D65 at 2°) with 4 mm thick glass sheets.
Claims20
A triple building glazing comprising:
- a glass sheet, wherein:
- a first face of the glass sheet comprises a system of layers produced by sputtering and comprising an infrared-reflecting metal layer,
- a second face of the glass sheet comprises a set of low-emissivity layers comprising an oxide layer deposited by gas pyrolysis, and
- wherein,
- the glazing has, for a 4 mm thick glass sheet, a light transmission which is not less than 60%,
- the oxide layer is on a glass surface designed to face an inside of a building and the system of layers is on a face of the glass sheet facing an interior of the triple glazing,
- the oxide layer has a surface roughness Ra of less than 10 nm,
- the system of layers produced by sputtering comprises a silver-based layer having a thickness of between 10 and 15 nm.
