Solar Control Low-E Glass

Formerly Solarban® R67 Glass

Solarban® R67 Solar Control Low-E Glass

There’s a completely new vision in transparent solar control, low-e window glass for your home. Solarban® R67 glass, the latest addition to the Solarban® family of products, is made with a soft, virtually imperceptible, neutral coating that lets your windows accurately reflect exterior light and color, while presenting a crisp, clear outdoor appearance.

Solarban® R67 glass adds brawn to its beauty, too. In the summer, it blocks more than 70% of the sun’s radiant heat energy when used in a standard ¾-inch, dual-pane residential window. In the winter, excellent insulating performance (signified by a U-value of 0.25) helps trap furnace heat. Combined, this performance contributes to year-round energy savings.

As an added bonus, Solarban® R67 glass has a Tdw-ISO rating of 0.41. That means, compared to standard dual-pane windows with clear glass, Solarban® R67 glass cuts the risk of fading damage to your furnishings, fabrics and carpeting by nearly half.

If you want the look of brilliantly clear windows that flood your home with natural light, reduce its seasonal cooling and heating demands and protects its most colorful treasures from sun damage, ask for Solarban® R67 glass by Vitro Glass.

Glass Comparison

Solarban® R67 insulating glass unit vs. standard insulating glass unit
Solar Heat Gain Coefficient
Visible Light
Ultraviolet Energy
Winter Furnace Heat
Standard Insulating Glass Unit Solarban® R67 Insulating Glass Unit Benefits
Solar Heat Gain Coefficient 0.75 0.29 Transmits 63% less solar energy to help keep homes cooler in the summer and reduce cooling energy costs
Visible Light Transmittance 81% 55% Allows high level of visible light transmittance and exterior clear glass appearance
U-Value 0.48 0.25 Insulates as much as 48% better than standard clear insulating glass
Ultraviolet Energy 58% 13% Blocks 45% of UV energy, a common contributor to fabrics, carpet and furniture fading
Damage Weighted Transmittance * 0.74 0.41 Minimizes the total potential for fading damage by 45%
*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.

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® R67 insulating glass. Actual glass performance may differ due to glass thickness, gas fill and glass to frame ratio.
