Solar Heat Gain Coefficient: Why SHGC Matters to Your Home

There are a lot of technical terms attached to modern windows and doors because of the technological advancement in recent years. One such term you may have read about is “Solar Heat Gain Coefficient” (SHGC). Now you may be wondering what this means for your home and why it should matter if you’re thinking of replacing your windows and doors.

SHGC refers to the fraction of solar energy transferred through the glass of windows and doors. This is rated by the National Fenestration Rating Council (NFRC) between 0 and 1. The lower the rating, the better the product is at reducing the amount of solar heat that gets into the house.

Now, why should this matter for your home in Atlanta?
