WebThe solar heat gain coefficient (SHGC) is an index describing the proportion of light that is let through a window. The larger the SHGC, the more light that can enter through the window. SHGCs range from approximately 0.70 for single clear glass to 0.31 for low emissivity glass (toned or coated glass). For coloured glass the SHGC has to be ... Solar gain is most frequently addressed in the design and selection of windows and doors. Because of this, the most common metrics for quantifying solar gain are used as a standard way of reporting the thermal properties of window assemblies.
