As you browse for new windows, you might have noticed certain terms like “SHGC rating” or “U-value” in several products. These are indicators that can help you determine which replacement windows are beneficial for your home in terms of indoor comfort and overall energy efficiency.
But what’s the difference between the two?
What Is SHGC?
The solar heat gain coefficient (SHGC) rating measures how much solar heat gets inside the home as soon as it reaches the glass. It’s measured between zero and one, with lower ratings indicating that the glass allows less solar heat to enter your home. It means that windows with higher SHGC ratings are beneficial in areas that experience harsh winters. Meanwhile, those with lower ratings are more effective in regions with warmer climates.
What Is U-Value?
U-value, meanwhile, measures the rate of heat loss as it passes through a window. In other words, it is a perfect indicator of a window’s ability to insulate. U-value, which is also known as the U-factor, has a rating that falls between 0.20 and 1.20. Like SHGC, lower values mean the window assembly, which includes the glass and the frames, has better insulation properties. It is an important rating that you shouldn’t disregard when planning your window replacement project.
Which Rating Is Best for Your Home?
When choosing new windows, you should consider your local area’s climate as well as your preferences. The SHGC ratings and U-value must be well-suited to your environment to maximize your home’s energy efficiency and comfort. If you want to keep your home naturally cool during the summer, consider windows that have SHGC ratings of 0.25 or lower and U-value of 0.30 or lower. With these, your windows will not only ensure efficient energy performance for your home but also minimize your HVAC requirements.
