Cooler in the Summer
The total solar energy transmitted through Solarban® 60 (2) glass is almost 50% less than that transmitted by standard clear insulating glass. With the Solarban® 60 (2) glass:
Warmer in the Winter
The winter night time U-Value (insulating value) of Solarban® 60 (2) glass is almost 50% better than standard clear insulating glass. Lower U-values mean higher performance, reduced furnace heat loss, and reduced heating energy costs.
Transmits Visible Light/Appearance
The Solarban® 60 (2) window transmits almost 90% as much desirable visible light as standard clear insulating glass. It provides:
o An exterior appearance similar to clear glass
o Glare control in bright, sunny climates
While Solarban® 60 (2) glass blocks 79% of damaging UV energy, it also blocks other contributors to fading, making it 24% better than standard clear insulating glass. It also helps protect interior furnishings, fabrics, and carpets from fading.

Note: Tdw-ISO represents potential fading damage caused by both UV and visible light. It is considered by the U.S. Department of Energy and the International Standards Organization (ISO) to be a more accurate barometer of fade resistance than UV transmittance alone. All comparisons are taken from the centre of glass based on an insulating unit containing 3/4″ insulating units, two 1/8″ (3mm) glass lights, and a 1/2″ (12mm) air-filled space for the standard clear insulating glass and argon gas-filled space for the Solarban® 60 insulating glass. Actual glass performance may differ due to glass thickness, gas fill, and glass to frame ratio. Solar Heat Gain Coefficient (SHGC) represents the solar heat gain through the glass relative to the incident solar radiation. It is equal to 86% of the shading coefficient. Figures may vary due to manufacturing tolerances. All tabulated data is based on the National Fenestration Rating Council (NFRC) methodology using the Lawrence Berkeley National Laboratory’s Window 5.2 software.
