What Makes an ENERGY STAR®-Rated Replacement Window?

Products that have earned the ENERGY STAR® label consume 20 to 30 percent less energy than other similar products. When it comes to replacement windows, choosing ENERGY STAR products doesn’t just help lower your energy bill; it also results in a more comfortable home.

What Makes an ENERGY STAR®-Rated Replacement Window?

In today’s post, your leading window replacement expert, Renewal by Andersen® of Seattle, discusses the qualities a window needs to have to be ENERGY STAR-rated.

U-Factor – This measures the way heat circulates through a window. Windows with a lower U-factor offer better insulation.

Solar Heat Gain Coefficient (SHGC) – This is a value of the amount of heat and light that can enter your home through the window. The lower the SHGC, the less air travels inside.

Air Leakage (AL) – This measures the amount of air that passes through the frame and joints per square foot of window space. A lower AL rating means less air flow. Renewal by Andersen® casement windows are created from quality materials that create weather-tight and energy-efficient windows.
