If you’re in the market for new windows, then you might notice that they have solar heat gain coefficient (SHGC) ratings. SHGC helps describe the energy efficiency of windows. This provides a guide so you compare products and decide which are the best windows for your home.
How Are Windows Rated for Efficiency?
Different products like windows, doors and skylights are tested by the National Fenestration Rating Council® (NFRC) based on their energy efficiency performance. The NFRC applies SHGC ratings on products as part of their certification program. One of the easiest ways to spot energy-efficient windows is to check the NFRC label, which can be spotted on all ENERGY STAR® certified windows, skylights and doors.
Why Should You Install SHGC-Rated Windows?
There are numerous window options available on the market. As such, it can be overwhelming for some homeowners, especially new ones, to pick the right windows for their home. Fortunately, window companies would state that SHGC ratings can help provide an easy side-by-side comparison of products. In fact, they could help recommend windows based on your current needs.
To find out if a product has a good SHGC rating, one means that it allows the maximum amount of solar heat to pass through a product while zero means that minimal heat passes through. For instance, a window with an SHGC rating of 0.30 means that only 30% of the sun’s heat can pass through your window. This is especially helpful if you live in warm areas as it doesn’t allow too much heat inside.
