What’s a Good SHGC Rating for Replacement Windows?

Appeal and durability are not the only factors you should consider when choosing windows. You also want to invest in units that can help you save on heating and cooling costs. Checking solar heat gain coefficient (SHGC) ratings is one way to determine how energy-efficient a window is. 

Continue reading to discover the ideal SHGC rating for your new windows. 

What Is SHGC?

SHGC ratings pertain to the amount of solar radiation that can penetrate windows, skylights or doors. They are expressed in a value between 0 and 1. The lower the SHGC, the better the ability of a product to keep heat from entering indoors. Moreover, SHGC ratings can guide you in choosing replacement windows suitable for your climate. 

What Is the Ideal SHGC Rating for Your Windows?

Your location will determine the ideal SHGC rating for your new windows. People in southern or warm climates often benefit from products with an SHGC rating below 0.27. It’s because they can aid in reducing indoor temperatures. 

Do you live in a colder location? If so, look for replacement windows with an SHGC rating between 0.30 and 0.60. They can help keep your humble abode warm, especially during winter months. As a result, your living space will remain comfortable. When your HVAC system doesn’t need to work as hard to heat your home, you’ll enjoy more savings on your energy bills.
