About NFRC

NFRC is an independent non-profit organization that establishes objective window, door, and skylight energy performance ratings to help you compare products and make informed purchase decisions in the following ways:

• Communicating the energy performance of products using the NFRC label
• Helping you understand the different categories of energy performance
• Providing tips, tools, and educational resources
• Narrowing your product search through our NFRC Certified Product Directory

The NFRC does not do the following:

• Sell, service, or recommend products, or endorse manufacturers. It simply provides objective energy performance ratings so you can make more informed decisions
• Install or guarantee the performance of improperly installed NFRC-certified windows, doors, and products
• Service warranties, provide rebates, or tax incentives
• Establish or enforce building codes

Contact NFRC with questions about how we establish our ratings, or how to get certified in the NFRC Certified Product Directory.

Mission: NFRC is committed to advancing continuous improvement of windows, doors, and skylights, contributing to making buildings more comfortable and energy efficient.
