Spectrally selective glazings that reduce the amount of solar energy entering a vehicle have been developed by PPG to enhance overall passenger comfort and help automotive designers and engineers manage the thermal environment in vehicles. That environment is being affected by such factors as the use of larger glass surfaces, smaller engines, fuel economy goals and refrigerant issues. To quantify the effects of a variety of solar control glazings on passenger comfort and thermal environments, PPG has conducted in-vehicle tests in Arizona evaluating the following glazing systems: the SUNGATE® Automotive windshield, which uses a transparent infrared-reflective coating; SOLARGREEN® Glass, a special composition that reduces infrared energy transmittance, and GL-20™ Glass, a deep-tint privacy glass.
