An In-Depth Look at Window SHGC and Why It Matters

When it comes to choosing replacement windows, the SHGC or solar heat gain coefficient is one factor to consider. Don’t let that fancy term scare you, though. Understanding this energy performance indicator might seem like a minor detail, but it’s crucial in helping you achieve significant energy savings for your home. Read on to learn more about it.

Window SHGC and Why It Matters

What Is a Window’s SHGC?

The SHGC is a measurement that shows the amount of solar heat that can pass through a window or any fenestration like a door or skylight. Essentially, it’s a rating that ranges from zero to one; the lower the number, the better the window is at blocking unwanted heat from the sun. Many people are unaware of this value when choosing new windows, but it’s an important aspect of window performance that needs to be taken into account.

Why Should I Care About a Window’s SHGC?

The SHGC of a window can have an impact on your home’s energy consumption. Lower SHGC means your windows allow less solar heat into your home, reducing the need for air conditioning. This, in turn, results in lower energy bills.

Not only that, but SHGC also impacts your home’s comfort levels. Windows with a high SHGC can make a room feel overly hot in the summer, causing discomfort. That said, such a rating that’s close to one is considered ideal in areas experiencing cold, harsh winters.

"We absolutely love our new windows. We had an awful wind yesterday and the windows keep the breeze and the sound out. Our previous windows did not do that and we are so happy with the quality and the installation was superb. The guys were professional and did a great job. I would recommend this company to any who want to improve their home. "
