Part of the process of finding the best replacement windows for your home is learning about their energy performance. The ratings that come with these products are vital in understanding which ones are the best fit for your home or for the region where you live. Among the many energy performance ratings you need to know about is the SHGC, or the solar heat gain coefficient. Window replacement service expert Renewal by Andersen® of Boise explains more below.
Understanding Window SHGC
A window’s SHGC refers to the fraction of solar radiation admitted through a window, both directly transmitted and absorbed, and subsequently released inward. In simpler terms, it measures the ability of a window to block the sun’s heat. This energy performance rating ranges between 0 and 1; the lower the number, the less solar heat is transmitted through the window.
The Importance of Window SHGC
You might be asking, “Why does this matter?” A window’s SHGC rating has a significant impact on your home’s energy efficiency and comfort level. A window with a high SHGC allows more solar heat to pass through, which can be great during cold winters when you want to make use of the sun’s warmth. On the other hand, a low SHGC is beneficial for hot summers, as it can help keep your interior cool by blocking out excessive solar heat.
When planning your house window replacement, it is important to discuss the matter of energy performance ratings with your contractor. According to ENERGY STAR®, the ideal SHGC for windows in this part of Idaho can be up to 0.42, provided that another energy performance rating, the U-factor, is between 0.27 to 0.30. Apart from this, you also have to consider your home’s orientation relative to the sun and any existing external shading to help you determine the desirable SHGC rating for your windows.
