Over the years, technological advancements in the manufacturing of windows have helped homeowners to reduce their heating and cooling costs while improving their comfort. However, shopping for new windows can be a daunting task, especially with several considerations you need to make.

For instance, you should check the U-value and SHGC ratings of windows to know if the units are energy-efficient. But what are U-value and SHGC?

Continue reading to learn more about them.

What Is SHGC?

SHGC, or solar heat gain coefficient, is the amount of heat that passes through the window glass from outside. It includes sunlight that is absorbed by the glass and then radiated into the room. The lower the SHGC, the less heat the window allows into the home.

Windows with a higher SHGC will benefit you if you live in a cold climate. They allow more heat into your home, making your space easier to heat during winter. The less strain on your HVAC system, the more energy you save.

What Is U-Value?

U-value is a measurement of a window’s insulating capacity. It represents the rate at which heat from the air passes through the glass. The better the insulation, the lower the U-value. Windows with a low U-value are commonly used to keep the heat in the room in cold climates or during the night.

When purchasing new windows, it’s important to choose products that are suitable for your climate. Always consult local experts so that you can be properly guided when making a decision.
