Winter. Spring. Summer. Fall. Four reasons to pick 70/36.

Maintaining a comfortable indoor environment is a challenge when temperatures fluctuate, sometimes dramatically, throughout the day, between seasons, and across climate zones. ClimaGuard 70/36 from Guardian Glass is designed for all seasons. It insulates in the winter, blocks heat in the summer and makes homes more comfortable and energy efficient all year long.

All-season comfort

Saves money on utility bills in the cooler and warmer months

Thermal insulation

50% more insulating than standard clear glass

Solar control

Blocks up to 40% more unwanted solar energy than dark-tinted float glass

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.
