National Fenestration Rating Council
Purchasing windows, doors, and skylights is a significant investment and complex purchase decision. Everyone wants attractive and efficient products, but very few know what to look for at the shelf. That’s where we come in.
The 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
- Delivering friendly, expert support
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 the NFRC with questions about how we establish our ratings, or how to get certified in the NFRC Certified Product Directory.
Mission : The NFRC serves the public by driving widespread usage of fair, accurate, and credible energy performance ratings, serves members by giving them a voice in the ratings development process, and serves the industry by creating an environment of competition that drives energy performance.
Vision : We envision a future where every window, door, and skylight purchase decision is made using the NFRC label to evaluate energy performance.

AAMA-American Architectural Manufacturers Association
Since 1962, AAMA Product Certification, the original third-party window performance program, has provided manufacturers with the means to independently demonstrate product performance to their customers. The program went on to raise the bar even higher by earning ANSI-accreditation in 1972 – a credential still maintained today. The AAMA Certification Label tells customers that a sample of the product has been verified as conforming to the standards’ requirements through independent laboratory testing and follow-up on-site inspection of the manufacturer’s production line. Products authorized for certification and their manufacturers are also listed in the online AAMA Certified Products Directory, the industry’s preeminent resource for window and door products.
