What’s a Good SHGC Rating for Your Windows?

It can be noted that when replacing your doors, skylights or windows, experts would always advise checking the solar heat gain coefficient (SHGC) ratings of the products you’re getting. This allows you to understand how much solar radiation can pass through your home features. Many may still ask whether it’s really necessary. We’ll explain here why.

 Good SHGC Rating For Your Window

What Are SHGC Ratings?

SHGC ratings of window products are determined by the National Fenestration Rating Council® (NFRC) following the necessary tests the organization runs. The U.S. Department of Energy and the Environmental Protection Agency (EPA) use the SHGC ratings in assessing the energy efficiency of the windows for product certifications and federal incentive and rebate programs. 

These classifications are used to guide people in choosing the right windows, like energy-efficient windows. Along with other information, such as condensation resistance, visible transmittance and U-factor, these are indicated on product labels so that people can easily refer to them and make comparisons of the different window items.

The Ideal Rating for Your Windows

  • Southern climates relying on cooling, their windows should have an SHGC rating of less than 0.27.

  • In the mixed climates of the south and central regions, windows and skylights should have an SHGC rating of less than 0.30.

  • In the mixed climates of the North and Midwest, the SHGC rating for windows and skylights should be below 0.40.

  • In the colder climates of the North, a window’s SHGC rating is actually not as important as the U-factor. Remember that if air conditioning is used from time to time, the SHGC rating of windows should be less than 0.40. If air conditioning is not used, windows should have an SHGC rating of 0.30 to 0.60.

"I'm getting ready to do my 2nd round of window installation with Anderson Windows. I really appreciate the great financing options that they offer! They have top notch sales and installation experts who are very kind and considerate of their customers' wishes. The windows I have installed look great and I am so excited to get the next group of windows put in. My house looks so much brighter with my new windows. I definitely recommend Renewal by Andersen of St. Louis."

"We recently contracted with Renewal by Andersen to replace 5 windows in our home. First of all, we were very delighted that the time from contract to installation was less than two months. Joel and Craig arrived precisely at the agreed-upon time and spent less than four hours from start to completion of installation, including time to demonstrate opening/closing the windows and any questions we had. We were very pleased with the knowledge and professionalism of Joel and Craig, and, of course, we’re very pleased with the windows and how nice they look. We definitely recommend Renewal by Andersen."

"I replaced my front door and several windows. The install team did a great job with installation and clean up. Even covered floors and stairs. The team was very courteous and did a very professional job. Now our windows look great and we love our new door. I would recommend Renewal by Anderson in a heartbeat."

"We had a wonderful experience with Renewal by Anderson of St. Louis. From sales to office staff communication to installation everything was great. Our new windows are great quality, look amazing and improved the overall look of our house. We had four installed in August and will definitely be purchasing from Anderson for the rest of our windows in the future. I highly recommend! ❤️ Now it just needs to cool off outside so I can open them. 😃"
