Reflects heat—and the future

Almost everyone on earth has seen SunGuard® Solar Silver 20. Guardian supplied 167,000 square metres of it for the Burj Khalifa, the world’s tallest building. This reflective glass not only helps architects achieve futuristic designs, it immediately delivers energy savings. The glass reflects heat and solar radiation, making it a great product for hot environments and super-tall buildings.

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.

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.
