The NFRC is a non-profit organization that administers a uniform, independent rating and labeling system for the energy performance of windows. The Department of Energys ENERGY STAR program relies on NFRC tests results to determine whether a window can qualify for an ENERGY STAR label. All ENERGY STAR labeled windows and skylights qualify for tax credit.
Look for manufactures with many windows that have a U-Factor less than or equal to .30 (The Lower the U Factor the better the window insulates). Window manufactures with few tested windows could lead to problems getting your tax credit.
