SunGuard® SuperNeutral®

The best of both worlds

It is possible to have the best of both worlds. SunGuard® SuperNeutral® products transmit high levels of light and reduce solar heat gain. While their neutral appearance is strikingly similar to clear, uncoated glass, they provide powerful thermal insulation by reflecting specific wavelengths of solar radiation. As a result, the sun’s heat stays out but natural daylight is welcomed in.

By selectively transmitting natural sunlight, reflecting solar heat and insulating against fluctuating outdoor temperatures, SunGuard SuperNeutral architectural glass will reduce energy consumption and costs for heating, cooling and artificial lighting.

Guardian SunGuard SuperNeutral has several products to meet your high light transmission needs while still blocking solar heat, saving on energy costs and helping projects qualify for LEED® credits. SunGuard SN is available on two float-glass substrates: Guardian UltraClear® low-iron and ExtraClear® glass.


From the Hearst Tower to the Dubai Opera and the Leadenhall Building, many of the world’s greatest buildings rely on SunGuard SuperNeutral to let plenty of natural daylight stream in while refusing entry to solar heat.
