Displayed colours are intended to represent actual colour. Colour is a function of light and reflectivity and cannot be accurately portrayed online. Actual glass samples should be used to determine colour. Please order a sample and discuss colour with your Gujarat Guardian Representative 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.
