Understanding Energy Efficiency Windows

When you get your windows replaced, there are many features you want out of them, including functionality, beauty, affordability, and energy efficiency. According to the best home window replacement installer in Ballwin, MO, energy efficiency is considered the most important feature among windows for many reasons. When you begin looking at energy efficiency windows, there are a few terms you’ll need to understand.  

Energy Star 

While you’re window shopping from the best residential window replacement installer in Chesterfield, MO, any windows that have an Energy Star® 

label means it is Energy Star® certified. To be certified, a window must meet specific U-value ratings according to National Fenestration Ratings Council (NFRC) standards. 

NFRC 

The NFRC is who tests and compares energy efficient windows by performance. Multiple categories determine how energy efficient a window is, including the U-Factor, Solar Heat Gain Coefficient, Visible Transmittance, and Air Leakage. The U-factor measures the amount of heat loss or gain that transfers through a window. Solar Heat Gain Coefficient is what measures how well a window resists unwanted heat gain. Visible Transmittance tells you how well a window will light up your home in the daylight. Air Leakage, as you could probably guess, measures how much air will leak through the window. For more information on specific numbers, ask the best residential window replacement installer in Chesterfield, MO. 

AAMA  

Another easy way to determine whether you have energy efficient windows or not is if they have the AAMA Gold Label.  Windows with this label meet the American Architectural Manufacturers Association’s qualifications that include air leakage, water leakage, and structural strength. The best residential window replacement installer in Ballwin, MO can go over the AAMA Gold Label with you more specifically.
