NFRC Compliance Investigation Form
NFRC labels are an essential component of Energy Code enforcement in determining if window, door,
and skylight products meet local code requirements for U-factor and Solar Heat Gain Coefficient. They
may also be required to receive incentives from utilities or tax breaks.
Consumers, code officials, and other stakeholders may use this form to report to NFRC any labeling or other concerns.
Please provide the information requested below and remit to the NFRC for review and
possible investigation. NFRC will contact you if needed after a course of action is determined.
