If you would like to improve your home’s energy performance, you should learn about Solar Heat Gain Coefficient (SHGC.) Through energy-efficient windows that are equipped with SHGC values, your energy consumption could be reduced. 

The Importance Of Shgc Ratings For Your Home

What Is SHGC?

SHGC is a standard that measures how well a window blocks heat from the sun. The SHGC value is rated through a number between 0 and 1. In energy-efficient windows, glasses have SHGC values. It acts as a protective barrier that prevents the heat from getting inside. The SHGC helps your window’s insulation, preserving your home’s conditioned temperature.

SHGC Rating’s Importance

The SHGC rating is important for your home’s energy efficiency. A low rating is preferred, it means less solar heat is transmitted inside your home. The ideal SHGC rate for your home is 0.25 or less. When your window replacement contributes to a lower SHGC rate, it means that its insulation is great. With a low SHGC rating, your energy consumption will lower, too.

However, your SHGC rating still depends on the climate, location of your home and the shading outside. The placement of your window can affect your home’s SHGC rating. It’s important to maintain a low SHGC rating since sunlight can fade your walls, floor and furniture. Also, when the temperature constantly changes inside your home, your HVAC system tends to overwork, increasing your chances for an expensive utility bill. It’s best to hire a window contractor to guide you with your SHGC windows replacement.
