Low emissivity coated glass

Low-e glass is produced by Vaccum sputtering layers for coatings,including one or two layers of silver on glass.silver is the material with lowest emissivity which is a measure of a material's ability to radiate energy.ordinary clear glass has a surface emissivity level of 0.84,meaning 90% of the absorbed heat is emitted from the low-e coatings are applied to glass,the surface emissivity is reduced to less than 0.1.double silver low-e is a product with high light transmittance which dramatically reduces infrared transmission and solar heat is an exnt product choice for both warm and cold climates.
