Performance Values

This is a schematic picture of how coating works. It helps to keep the heat indoors, reflects solar radiation, and transmits visible daylight. The values of the above-mentioned characteristics are nominal for the central part of an IGU of the configuration, listed above. The values do not take into consideration the window section profile system or the material of the frames. Heat resistance value is representing only the central part of IGU (Rcenter) and given for Moscow climate region (outside air temperature -25 °C, inside air temperature +20 °C). Deviations are possible due to manufacturing and design tolerances. Calculations, terms and conditions are based on GOST national standard EN 410-2014 and GOST EN 673-2016. The calculations have been acquired with the help of software complex, Guardian online configurator.

Color

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.
