A window replacement project is not just about looking for the style that best fits your home’s aesthetic. It also about choosing replacement windows that are specifically designed to thrive when faced with the demands of your local climate.
Here’s what to look for:
A Deep Look at the Energy Performance Labels
When shopping for new windows, you will notice that the products have labels that indicate different levels of performance. These are created by the National Fenestration Rating Council (NFRC), and serve as an industry-standard rating system for not just windows, but also entry doors and skylights. These ratings are helpful in narrowing down your choices for the best windows.
As you examine these energy performance labels, it is important that you take note of two ratings that measure the window’s thermal performance: the U-factor and solar heat gain coefficient (SHGC).
The U-factor measures how quickly heat passes through windows. Its value ranges between 0.20 to 1.20. The lower the rating, the better the windows are in terms of insulation. Units with low ratings will help reduce indoor cooling requirements, especially in the summer.
Meanwhile, the solar heat gain coefficient measures the heat gained from direct sunlight. Its value ranges between 0.0 to 1.0. The lower the rating, the better the window is at resisting heat from sunlight. Your windows should also have the necessary low-emissivity (low-E) coatings to make this possible. With this, you can enjoy natural light without worrying about comfort issues.
