If you are planning to install new windows, you’ve probably heard the term solar heat gain coefficient (SHGC) being thrown around by your contractor. You may have even seen it on a label when canvassing for a new window. But what does it mean, and why is it so important that you get a good rating?
What Is SHGC?
SHGC may sound pretty technical, but it really is just a simple measurement that can help you achieve the desired increase or decrease in the amount of solar radiation passing through, absorbed or transmitted through your windows.
This measurement is expressed in numbers between 1 and 0, with 0 being the least amount of heat being allowed through a window, and 1 being the most.
Solar heat gain can help keep your room warm during the winter and provide free heating, but also cause that same room to overheat in the summer. This is why it is important to find the perfect SHGC value that depends on your climate and window orientation as well as shade, such as trees or blinds. Your window contractor can help you in this regard.
Understanding SHGC ratings and utilizing them properly is a great way to keep heating and cooling costs down, and picking the right balance will help keep your family comfortable throughout the year.
