As a homeowner, understanding solar heat gain coefficient (SHGC) could make a big difference to the comfort and energy efficiency of your home. In this post, we share essential information about window SHGC and why it matters when choosing windows.
What Is SHGC?
Window SHGC is a rating that shows how well a window blocks heat from the sun. The lower the SHGC, the less solar heat the window transmits. As a result, you can maintain your home’s energy efficiency and indoor comfort.
How Are SHGC Ratings Determined?
SHGC ratings are based on the ability of the glass to transfer solar heat. The rating is determined by testing the window’s ability to absorb and transmit solar radiation. The rating is then assigned on a 0-1 scale, with 0 denoting the lowest possible SHGC and 1 representing the highest SHGC possible.
Why Should I Care About Window SHGC?
So, why should something as technical as SHGC matter to you? Well, if you live in a hot climate, a window with a low SHGC can keep your home cooler by blocking more heat from the sun. This can significantly reduce your cooling costs, making your home more energy-efficient. Plus, in a city like Findlay, OH, where summers can get pretty warm, understanding and considering SHGC when choosing your windows can make a big difference.
What Is the Difference Between SHGC and U-Factor?
SHGC is often confused with U-factor, another term used to describe the energy efficiency of window units. U-factor measurements, on a scale of 0-1, indicate the rate of heat conduction through the window. Lower U-factor ratings indicate a more energy-efficient window unit. However, while both ratings measure the effects of sunlight on your home’s energy efficiency, the U-factor measures all forms of heat while SHGC only accounts for solar radiation.
