The Main Differences Between SHGC and U-Value

When shopping for new windows, take note that there are window performance requirements that need to be met to ensure optimal energy efficiency. For example, a specific solar heat gain coefficient (SHGC) rating and U-value will help determine whether a window is a good fit for your home and local climate. Such information may sound daunting for those who aren’t familiar with it, but we’ll help you gain a better understanding of these things through simple explanations.

Read on to learn more about SHGC and U-value.

U-Value

The U-value refers to the amount of heat transferred through a window. As a general rule of thumb, the lower the U-value, the better the insulation of the window — which means the window is capable of doing a good job of keeping the heat or cold out. A window with a lower U-value and good insulating properties can contribute to your home’s indoor comfort.

SHGC

The SHGC rating is an important consideration when looking for new windows. It tells you how much solar heat passes through the window. For households in cold-climate regions, a high SHGC rating is often ideal as it allows more solar radiation to pass through the window, providing free heating for the home.

But before you select any windows for your home, consult local professionals who are knowledgeable and familiar with the weather conditions in your area. Local contractors will know which windows would work best for your home.
