NFRC Meetings
The NFRC holds two meetings per year: a Spring Committee Week and a Fall Membership Meeting.
At each meeting subcommittees and committees convene to debate and move forward important issues relating to the energy ratings
of the fenestration industry.Visit our Meetings page for more information.
NFRC ANS Standards
NFRC is an American National Standard Institute (ANSI) Accredited Standards Developer (ASD) and develops and administers
comparative energy and related rating programs for fenestration products.

Why is it Important to Vote?
Throughout NFRC’s history, improvements have been made by those who organized, networked, joined forces, expressed their opinions openly – and voted.

Get your product certified!
NFRC has developed and operates a uniform national rating system for the energy performance of fenestration products, including windows, doors, skylights, and similar products.
The linchpin of the Rating System is a procedure for determining the thermal transmittance ("U-factor") of a product. The U-factor rating procedure is supplemented by procedures for rating products for solar heat gain coefficient ("solar heat gain" or "SHGC"), visible transmittance ("VT"), air leakage ("AL"), and condensation resistance ("CR"). Together, these rating procedures, as set forth in documents published by NFRC, are known as the NFRC Rating System.
Guidelines for requesting product certification
NFRC's Component Modeling Approach
The Component Modeling Approach (CMA) Product Certification Program enables whole product energy performance ratings for commercial (non-residential) projects.
The concept behind component modeling is performance data from the three primary components that make up a fenestration product are used for obtaining an overall product performance rating.
