A Beginner’s Guide to SHGC

Let’s face it – windows can cost a lot. That said, you want to make sure you’re getting the most value out of your money when choosing windows. This is why it’s very important to pay attention to certain factors that dictate your window’s efficiency. One of these factors is the SHGC or solar heat gain coefficient. What is it and why is it important for you? Our window replacement experts give you a rundown of the matter.

SHGC In a Nutshell

When the sun shines on your windows, part of the heat is reflected away from the window, another part is absorbed, and another part passes through the glass and into your home. The SGHC refers to the third part of solar heat radiation. This means the higher the SHGC, the greater part of heat radiation gets through.

How to Measure SHGC

SHGC is often rated on a scale of 0 to 1. 0 means heat is completely reflected or absorbed by the window, while 1 means every bit of heat passes through. Window and roof replacement experts say that a window should have an SHGC of around .3 to .6 to be considered efficient enough for the average household.

How Does Good SGHC Affect Your Home?

Windows with good SHGC can have a big impact on your home’s energy efficiency and the level of comfort in your home. This is especially true for homes in areas known to have very hot summers, where every bit of heat reduction helps the HVAC conserve energy while keeping the home cool enough.

Getting Windows With Good SHGC

Although you may be tempted to purchase your own high SHGC windows, you’re much better off working with certified exterior renovations experts. A certified contractor will have better access to high-quality windows and will most likely have the tools and experience necessary to ensure that your windows are installed according to manufacturer’s specifications.
