Question

Quizplus · Accepted Answer

The NFRC label on a window must include the U-value and solar heat gain coefficient. While other factors such as visible transmittance and air infiltration may also be included on the label, the U-value and solar heat gain coefficient are specifically required by the NFRC. The shading coefficient, for example, is no longer used in the NFRC rating system.
