What Solar Heat Gain Coefficient means
Solar Heat Gain Coefficient means a rating that measures how much solar heat passes through a window or glass assembly.
Solar Heat Gain Coefficient is one of the most useful energy terms for Arizona building glass and film decisions. A lower SHGC means less solar heat enters through the glass. This matters for west- and south-facing glass, rooms that overheat, storefronts with sun exposure, and customers evaluating window film or replacement glass.
This term helps customers understand why glass selection is not only about size and price; safety, comfort, performance, and building requirements can also matter. Use this term when a customer is comparing comfort, code, safety, energy, or sound-control requirements.
