According to the Renewal by Andersen website their windows are ENERGY STAR® certified. This means that they meet or exceed energy efficiency guidelines set by the U.S. Environmental Protection Agency.
In order to be ENERGY STAR certified a window must meet certain criteria for energy efficiency. These include criteria for solar heat gain air leakage and U-factor.
Solar heat gain is a measure of how much heat from the sun is let into a home through the windows. The lower the solar heat gain the more energy efficient the window is.
Air leakage is a measure of how much air can pass through a window. The less air that can pass through the more energy efficient the window is.
U-factor is a measure of how much heat is lost through a window. The lower the U-factor the more energy efficient the window is.
Renewal by Andersen windows are designed to be energy efficient. They use Low-E glass which helps to reduce solar heat gain and minimize heat loss. Their windows also have a tight seal that helps to reduce air leakage.
