Picking Windows With Good SHGC Ratings

When shopping for new windows from trusted window installation companies, you might notice that they have SHGC ratings. SHGC stands for solar heat-gain coefficient, which helps describe the energy efficiency of the respective windows. This helps you decide which are the best windows for your home. In this post, Window World of Boston guides you on how to pick windows with good SHGC ratings. 


How Are Windows Tested for Efficiency?

Windows, doors and skylights are tested by the National Fenestration Rating Council (NFRC) based on their energy efficiency performance. The NFRC then sets SHGC ratings on compliant products as part of their certification program. An easy way to spot energy efficient windows is to look for the NFRC label, which can be found in all ENERGY STAR®-certified windows, skylights and doors.

Why Should You Pick SHGC-Rated Windows?

With all of the window options available on the market today, it can be daunting for some homeowners to pick the right one for their home. After all, windows are a significant investment as well. Window installation contractors will tell you that SHGC ratings can help you compare products side-by-side. They can even recommend the products that are best for your budget and situation.

When looking at the SHGC rating, “1” pertains to the maximum amount of solar heat that can pass through a window, while “0” means that only a small amount is allowed through. For example, an SHGC rating of 0.20 means that only 20% of the transmissible solar heat can pass through your window. It’s also worth noting that you need to consider other factors such as air leakage, visible transmittance, condensation resistance and U-factor. All of these factors work together to help you determine the best energy-efficient window for your home.
