Second-generation low-E coatings improve light transmission in glazing without compromising mechanical value performance

The popularity of glass with highly reflective coatings continues to decline as architects increasingly make go round to the use of clear glass substrates in combination with spectrally selective coatings.

To contract energy use, low-emissivity coatings are being used in lieu of glass that is either uncoated or has a highly reflective coating.
