Solarban® 70 Solar Control Low-E Glass

Windows made with Solarban® 70 glass give today’s homeowners the ultimate solar control glass on the market. Solarban® 70 glass is the industry’s first triple silver low-e coating and is still the most advanced low-e coating available today. Solarban® 70 glass blocks nearly ¾ of the sun’s heat energy while allowing more than 60% of daylight to pass through. This winning combination helps cut summer cooling costs and reduces 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® 70 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® 70 glass by Vitro Glass.

IGU		 Benefits
Solar Heat Gain Coefficient 0.75 0.26 0.24 Transmits either 64% less (double) or 68% less (triple) solar energy to help keep homes cooler in the summer and reduce cooling energy costs.
Visible Light Transmittance 81% 63% 57% Allows high level of visible light transmittance and exterior clear glass appearance
U-Value 0.48 0.24 0.18 Insulates as much as 50% better (double) or 62.5% better (triple) than standard clear insulating glass
Ultraviolet Energy 58% 4% 4% Blocks 94% of UV energy, a common contributor to fabrics, carpet and furniture fading
         
Damage Weighted Transmittance * 0.74 0.43 0.44 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® 70 glass can minimize fading damage across the entire solar spectrum more effectively than glass designed primarily to block UV light.

All comparisons are center of glass based on an insulating unit containing 3/4" insulating units; two 1/8" (3mm) glass lites and a 1/2" (12mm) air-filled space for the standard clear insulating glass and 90% argon gas-filled space for the Solarban® 70 insulating glass. Actual glass performance may differ due to glass thickness, gas fill and glass to frame ratio.
