FOREWORD

The National Fenestration Rating Council, Incorporated (NFRC) has developed and

operates a uniform rating system for energy and energy-related performance of

fenestration products. The Rating System determines the U-factor, Solar Heat Gain

Coefficient (SHGC) and Visible Transmittance (VT) of a product, which are mandatory

ratings for labeling NFRC certified products, are mandatory ratings for inclusion on label

certificates, and are supplemented by procedures for voluntary ratings of products for Air

Leakage (AL), and Condensation Resistance. Together, these rating procedures, as set

forth in documents published by NFRC, are known as the NFRC Rating System.

The NFRC Rating System employs computer simulation and physical testing by NFRC-

accredited laboratories to establish energy and related performance ratings for fenestration

product types. The NFRC Rating System is reinforced by a certification program under

which NFRC-licensed responsible parties claiming NFRC product certification shall label

and certify fenestration products to indicate those energy and related performance ratings,

provided the ratings are authorized for certification by an NFRC-licensed certification and

Inspection Agency (IA).

The requirements of the rating, certification, and labeling program (Certification Program)

are set forth in the most recent versions of the following as amended, updated, or

interpreted from time to time:

• NFRC 700 Product Certification Program (PCP).

• NFRC 705 Component Modeling Approach (CMA), Product Certification Program

(CMA-PCP).

Through the Certification Program and the most recent versions of its companion programs

as amended, updated, or interpreted from time to time:

• The laboratory accreditation program (Accreditation Program), as set forth in the

NFRC 701 Laboratory Accreditation Program (LAP).

• The IA licensing program (IA Program), as set forth in NFRC 702 Certification Agency

Program (CAP).

• The CMA Approved Calculation Entity (ACE) licensing program (ACE Program), as

set forth in the NFRC 708 Calculation Entity Approval Program (CEAP).

NFRC intends to ensure the integrity and uniformity of NFRC ratings, certification, and

labeling by ensuring that responsible parties, testing and simulation laboratories, and IAs

adhere to strict NFRC requirements.

NFRC 101-2026[E0A2] Page ii

In order to participate in the Certification Program, a Manufacturer/Responsible Party shall

rate a product whose energy and energy-related performance characteristics are to be

certified in accordance with mandatory NFRC rating procedures. At present, a

Manufacturer/Responsible Party may elect to rate products for U-factor, SHGC, VT, AL,

Condensation Resistance, or any other procedure adopted by NFRC, and to include those

ratings on the NFRC temporary label affixed to its products, or on the NFRC Label

Certificate. U-factor, SHGC and VT, AL, and Condensation Resistance rating reports shall

be obtained from a laboratory that has been accredited by NFRC in accordance with the

requirements of the NFRC 701.

The rating shall then be reviewed by an IA which has been licensed by NFRC in

accordance with the requirements of the NFRC 702. NFRC-licensed IAs also review label

format and content, conduct in-plant inspections for quality assurance in accordance with

the requirements of the NFRC 702, and issue a product Certification Authorization Report

(CAR), or approve for issuance an NFRC Label Certificate for site-built or CMA products

and attachment products. The IA is also responsible for the investigation of potential

violations (prohibited activities) as set forth in the NFRC 707 Compliance and Monitoring

Program (CAMP).

Ratings for products that are labeled with the NFRC Temporary and Permanent Label, or

products that are listed on an NFRC Label Certificate in accordance with NFRC

requirements, are considered to be NFRC-certified. NFRC maintains a Certified Products

Directory (CPD), listing product lines and individual products selected by the

manufacturer/responsible party for which certification authorization has been granted.

NFRC manages the Rating System and regulates the Product Certification Program (PCP),

Laboratory Accreditation Program (LAP) and Certification Agency Program (CAP) in

accordance with the NFRC 700 (PCP), the NFRC 701 (LAP), the NFRC 702 (CAP), the

NFRC 705 (CMA-PCP), and the NFRC 708 (CEAP) procedures, and conducts compliance

activities under all these programs as well as the NFRC 707 (CAMP). NFRC continues to

develop the Rating System and each of the programs.

NFRC owns all rights in and to each of the NFRC 700, NFRC 701, NFRC 702, NFRC 705,

NFRC 707, NFRC 708 and each procedure, which is a component of the Rating System,

as well as each of its registration marks, trade names, and other intellectual property.

The structure of the NFRC program and relationships among participants are shown in

Figure 1, Figure 2, and Figure 3. For additional information on the roles of the IAs and

laboratories and operation of the IA Program and Accreditation Program, see the NFRC

700 (PCP), NFRC 701 (LAP), and NFRC 702 (CAP) respectively.
