Low-emissivity (low-e) glass coatings were developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted. A microscopically thin transparent coating allows low-e glass to reflect exterior heat in warm temperatures and hold in heat during cold temperatures, making buildings light, bright and energy-efficient.
Vitro Architectural Glass (formerly PPG glass) offers two types of low-e coated glasses: Solarban® solar control low-e glasses and Sungate® passive low-e glass.
