Solar heat gain coefficient (SHGC) isn’t something most homeowners consider. It is very technical sounding and seems like something that is better left to professional window experts. But in order to truly understand your windows and how well they perform, it is important that you have a working understanding of SHGC.

What Is the Solar Heat Gain Coefficient?

To put it in the simplest of terms, the SHGC measures how well a window blocks heat from the sun. This means that a window with a low SHGC rating will reduce the amount of unwanted heat from the sun that comes in through your windows. SHGC is measured by a number between 0 and 1. The closer a window’s SHGC rating is to zero, the less heat it absorbs and transmits.

If you live in a climate with punishingly hot afternoons, especially during the summer months, window contractors recommend getting replacement windows with low a low SHGC rating to help manage your interior temperature and reduce air conditioning costs.

SHGC Performance Testing and Labeling

The National Fenestration Council® (NFRC) is a non-profit organization that offers an energy efficiency certification and labeling not just for windows, but for doors and skylights as well. Its aim is to provide consumers and builders with a reliable way to determine a product’s energy efficiency so that they can compare brands and make informed decisions when it comes to a home’s overall energy performance.
