Investing in the right replacement windows in Louisville, KY, can add functionality and curb appeal to your home. When it comes to comfort, however, it helps to have an idea of how energy-efficient your window is. This is where energy efficiency ratings come in.

Renewal by Andersen® of Kentucky discusses the energy efficiency standards set by the National Fenestration Rating Council (NFRC).

The NFRC

This non-profit organization helps consumers choose energy-efficient products. They qualify and label fenestration products such as windows and doors through a series of tests and certification processes. The NFRC label will be a good indication if your bay windows offer superior energy efficiency and performance.

Their Energy Efficiency Ratings

Becoming familiar with these standards will help you select the window that will let you enjoy a cozier home and more energy savings.

• U-Factor – This determines the amount of heat leaving your home. The lower the value, the better your window is at trapping heat in your home.
• Solar Heat Gain Coefficient (SHGC) – The value of this rating ranges from zero to one. The lower the number, the better your window is in minimizing heat buildup in your home.
• Visible Transmittance (VT) – This measures the amount of light that enters your living area. The higher the number, the more daylight you will enjoy in your interior.
• Air Leakage – This measures the amount of air that enters your home. The lower the number, the more likely your window will keep drafts at bay.
