What Is a Good SHGC Rating for Your New Windows?

When it comes to door installation or replacing windows and skylights, it is critical to check the solar heat gain coefficient (SHGC) ratings of the products you are considering purchasing. This way, you are able to know how much solar radiation can pass through the windows. To learn more about the basics surrounding this topic, read further.

The Importance of SHGC Ratings

It can be noted that the SHGC ratings of window products are determined by the National Fenestration Rating Council (NFRC). They run tests on the windows so that they can assign appropriate ratings. Furthermore, the U.S. Department of Energy and the EPA use the SHGC ratings in assessing the energy efficiency of the windows for product certifications and federal incentive and rebate programs. 

These ratings basically help people choose the right replacement windows. Along with other information such as condensation resistance, visible transmittance, and U-factor, these are indicated on product labels so that homeowners or consumers can easily refer to them and make comparisons of different window products.

The Ideal Rating For Your Windows

  • For Southern climates that rely on cooling, 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.
