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.
Over the past 60 years, Solarban® glass and its precursors have been at the forefront of multiple groundbreaking advancements in glass performance, becoming one of the most trusted and proven solar control, low-e glasses that grace countless COTE® award-winning and LEED® certified buildings and structures.
2025 serves as a significant milestone for several of our Solarban® glass products:
- Solarban® 60 glass – 25th Anniversary
- Solarban® 70 glass – 20th Anniversary
- Solarban® 90 glass – 10th Anniversary
