Abstract (en)

[origin: WO2006097513A1] The invention concerns a low-emissivity glazing. The inventive glazings comprise an assembly of thin layers including at least one metal layer reflecting infrared rays between one or more dielectric layers located between the metal layer and the glass sheet and on the metal layer, the light transmission for one clear float glass sheet 4 mm thick coated with said layers being not less than 83 %, the metal layer being selected such that the emissivity is not higher than 0.042.
