Solar Control Low-e Glass

High-performance glass lets the natural light in and keeps the heat energy out.

SOLARBAN® 70XL Solar Control Low-e Glass

Windows made with Solarban 70XL glass give today’s homeowners the ultimate solar control glass on the market. Solarban 70XL glass is the industry’s first triple silver low-e coating and is still the most advanced low-e coating available today. Solarban 70XL glass blocks nearly ¾ of the sun’s heat energy while allowing more than 60 percent of daylight to pass through. This winning combination helps cut summer cooling costs and reduce energy expenses related to indoor lighting while simultaneously protecting furniture, fabrics and carpets from fading.

But, the potential energy savings don’t stop there. Even in cold climates—nighttime or daytime—the performance of Solarban 70XL low-e glass with its improved u-value helps to cut winter heat loss from residential windows in half compared to ordinary clear glass.

When you want windows that provide the ultimate in energy savings—with a clear glass view that lets the natural light in and reduces solar heat gain—ask for Solarban 70XL glass by PPG.

Glass Comparison

Solarban 70XL insulating glass unit vs. standard insulating glass unit
Solar Heat Gain Coefficient
Visible Light
Ultraviolet Energy
Winter Furnace Heat
Standard Insulating Glass Unit Solarban® 70XL Insulating Glass Unit Benefits
Solar Heat Gain Coefficient 0.75 0.27 Transmits 64% less solar energy to help keep homes cooler in the summer and reduce cooling energy costs
Visible Light Transmittance 81% 64% Allows high level of visible light transmittance and exterior clear glass appearance
U-Value 0.48 0.24 Insulates as much as 50% better than standard clear insulating glass
Ultraviolet Energy 58% 6% Blocks 94% of UV energy, a common contributor to fabrics, carpet and furniture fading
Damage Weighted Transmittance * 0.74 0.43 Minimizes the total potential for fading damage by 42%
*Damage Weighted Transmittance is calculated according to a function called Tdw-ISO, developed by the International Standards Organization (ISO) and published by the International Commission on Illumination (CIE), the world’s leading technical organization on lighting and illumination. The Tdw-ISO calculation measures fading risk from solar radiation across the entire solar light spectrum, from UV light (280-380 nanometers) through visible light (390-780 nanometers). According to the CIE standard, which is considered more comprehensive than UV rating alone, Solarban 70XL glass can minimize fading damage across the entire solar spectrum more effectively than glass designed primarily to block UV light.
