Technical Documents

One of NFRC's main functions is to promulgate technical standards that establish uniform procedures for determining the various energy performance ratings: including U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance (VT), and Condensation Resistance.

2017 (Current Document Cycle) - Revised July 2017

NFRC 2017 documents have been approved by NFRC membership and The Board of Directors for publication.

For NFRC Certification of fenestration products, either WINDOW5/THERM5 or WINDOW6/THERM6 may be used for the simulation of those products. However, after July 1, 2011 only WINDOW6/THERM6 will be authorized for NFRC Certification.

By accessing and downloading NFRC documents from this webpage, the user agrees to abide by the terms of use. To request a previous edition of an NFRC document, please complete the form HERE.

Note: Errata or addendums will be noted in the footer of each documents. e.g. [E1A0] would mean that there is one errata published to the original document.
