If you’re in the market for new windows for your home then you’ve probably heard your contractor talk about SHGC ratings at one time or another, especially in the context of energy efficiency. SHGC stands for solar heat gain coefficient. It may sound pretty technical but it’s actually quite easy to understand. In today’s post, wood window installation experts Homecraft Inc. gives you the lowdown on SHGC ratings so you can be better informed when purchasing new windows.
What is Solar Heat Gain Coefficient?
Simply put, the solar heat gain coefficient represents the amount of solar radiation that is admitted through your windows, doors and skylights – either directly or absorbed and subsequently released inside your home.
It is measured by a number between 0 and 1 and the lower the numerical value is, the less solar heat is admitted or transferred. Most modern replacement windows will have an SHGC rating prominently displayed so buyers can make an informed decision when shopping around for new windows.
Why Is the SHGC Rating Important?
As mentioned above, the lower the SHGC rating is, the less solar heat it admits and the greater its shading ability. While a window with a low SHGC rating is more effective in collecting solar heat during the winter, it may cause the interior of your home to overheat during the summer.
To determine the optimal SHGC for a particular window, you will need to think about the climate where you live, the location of your windows, and even the shade directly outside the window. For best results, it is always best to consult with your window installer.
