The ENERGY STAR label

The ENERGY STAR label is widely recognized as the official mark of energy efficiency. Consumers and businesses alike rely on this easily identifiable blue label to make informed decisions that are based on reliable and unbiased information. But how do you understand ENERGY STAR Labels & Specifications? Energy Star-certified window labels must include at least four performance value ratings: ER, VT, U-factor, and SHGC. However, only the U-factor and Solar Heat Gain Coefficient are required for door labels. Manufacturers can include ratings for condensation resistance (CR), air leakage (AL), and information on CSA certification. In this article, we will take a look at the energy star labels and specifications so you can make a sound decision while buying windows.
