Glass is one of the most popular and versatile building materials used today, and it provides a dramatic aesthetic. But the beauty of glass is pointless if the people inside the building are uncomfortable or if energy inefficiency makes the building too expensive to operate.
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. Learn about low-e glass and how it works in the Glass Education Center.
Solarban® glass is a spectrally selective glass option which reduces long (ultraviolet) and short wave (infrared) radiation, while at the same time allowing visible light to be transmitted through the glass. Solarban® glass products by Vitro Glass let you specify larger spans of glass that maximize natural daylighting without sacrificing thermal efficiency.
With a range of options, the Solarban® family of glass products features a clear aesthetic and among the highest light-to-solar gain (LSG) ratios in the industry and can be combined with tints for even better performance.
