Vitro Architectural Glass

Solar Control and Passive Low‑e Glasses

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.

Solarban® Acuity® Series

With the Solarban® Acuity® Series, you can upgrade from coated clear glass for just a fraction of the total installed façade cost.
