US Patent 8722210 Low emissivity glass and method for manufacturing the same

The present invention relates to low emissivity glass and to a method for manufacturing the same. The low emissivity glass comprises: a low emissivity layer; and a dielectric layer formed on the low emissivity layer, wherein the glass has an emissivity of 0.01 to 0.3 and a visible transmittance of 70% or more. According to the present invention, low emissivity glass having good emissive performance while also exhibiting high visible transmittance can be provided. Further, according to the present invention, the manufacturing process for the above-described low emissivity glass can be simplified, and initial investment amount can be reduced.
