Spectrally Selective Glazing

Spectrally Selective Glazing is high-performance glazing that admits as much daylight as possible, while preventing transmission of as much solar heat as possible.

By controlling solar heat gains in summer, preventing loss of interior heat in winter, and allowing occupants to reduce electric lighting use by making maximum use of daylight, spectrally selective glazing significantly reduces building energy consumption. Glazing’s with a selectivity factor greater than 1.25 can be considered as a “Spectrally Selective Glazing.” The calculation of spectrally selective glazing follows the formula described in the “Selectivity” definition.
