SunGuard® SuperNeutral®

SN 70/35

High on your list for low heat gain

Excellent light transmission is possible without the heat that usually comes with it. SunGuard® SuperNeutral® (SN) 70/35 is a neutral blue glass that offers solar protection while reducing the need for artificial light. Ideal for fully glazed facades and large frame windows, SN 70/35 combines excellent solar protection combined with outstanding thermal insulation.

Energy savings

Through thermal insulation and reduced artificial light

Low solar heat gain

While maintaining high light transmission

Available on laminated glass

For acoustics, security and comfort

Matching appearance

For both annealed and heat-treated applications

Color Disclaimer Color Disclaimer

Displayed colors are intended to represent actual color. Color is a function of light and reflectivity and cannot be accurately portrayed online. Actual glass samples should be used to determine color. Please order a sample and discuss color with your Guardian Architectural Design Manager to ensure you are pleased with your SunGuard selection before ordering glass for your project.

Thermal Stress Disclaimer Thermal Stress Disclaimer

The thermal stress guideline is only a rough guide to the thermal safety of a glazing. Other factors such as large glass areas, shapes and patterns, thick glass, glass damaged during shipping, handling or installation, orientation of the building, exterior shading, overhangs/fins that reduce wind speed, and areas with high daily temperature fluctuations can all increase the probability of thermal breakage. The results shown are not for any specific glazing installation and do not constitute a warranty against glass breakage.
