Solar radiation passes through the window. Some windows can do a better job of reducing solar heat gain and this capacity is often measured using the solar heat gain coefficient (SHGC).
Windows with low SHGC ratings are better at preventing excess heat from entering your living space. On the other hand, those with high SHGC ratings allow more heat into your home, making them useful during winter or in colder regions.
Learn more about SHGC and find the ideal rating for your home using these tips from a reputable window and exterior renovations expert.
Southern parts of the country have warmer climates that make windows with a low SHGC rating ideal for keeping their spaces cool and energy consumption low. Windows that can let natural sunlight in rooms without much heat should have an SHGC rating of at least 0.27.
Colder regions in the country usually receive limited sunlight, so getting as much heat from outside is a top priority for homeowners in these locations. During window replacement, window professionals recommend windows with SHGC ratings of 0.30 to 0.60 to keep houses toasty during the colder seasons.
The northeastern and midwest parts of the country rely both on heating and cooling. For homes in these regions, windows with an SHGC rating lower than 0.40 is recommended. Meanwhile, southeast regions in the country have hot, humid summers and freezing winters, so windows with an SHGC rating of 0.30 or below work well for properties in these places.
