California's varied climate zones, from the temperate coastal regions to the arid inland areas, demand windows with specific performance characteristics. In Southern California metros like Irvine and Santa Clarita, mitigating intense solar heat gain is paramount, often achieved with advanced low-E coatings and spectrally selective glass.
