CRRC WALL RATING PROGRAM
Last Updated December 3, 2021
Beginning January 17, 2022, the CRRC will offer product ratings for companies interested in having their exterior wall products listed and labeled with information about the product’s surface radiative performance (solar reflectance and thermal emittance). The ratings will be published on the CRRC Rated Wall Products Directory and CRRC Product Labels.
The ratings will enable end users to identify eligible products for compliance with various codes and programs that require or promote the use of solar-reflective walls for reducing building energy use and/or mitigating the impacts of the urban heat island effect.
CRRC WALL RATING PROGRAM OVERVIEW WEBINAR
Any exterior wall product can be rated as long as it is in compliance with the CRRC-2 Wall Product Rating Program Manual. This document contains the details for program participation and the detailed requirements for the testing, weathering, and rating of exterior wall materials.
INTERESTED IN GETTING A PRODUCT RATING?
A company must first apply to become a Licensee in the CRRC Wall Rating Program before applying for a product rating(s). Since the CRRC Wall Rating Program is separate and distinct from the CRRC Roof Rating Program, companies must become a Licensee in the program regardless of whether they are also licensed to participate in the Roof Rating Program.
To apply as a CRRC Wall Licensee, please download and complete the following documents:
Please send the completed Licensee Application (CRRC WF-1) to [email protected]. The Licensee Agreement is not due until the program opens in January 2022.
Applicants will be provided with information about completing the Licensee application process and how to apply for a product rating(s) when the program is open in January 2022. Payment of the Licensee fee is not due until the program opens. The relevant fees can be found in the CRRC Wall Rating Program Fee Structure.
INTERESTED IN BECOMING AN ACCREDITED MANUFACTURING TESTING LABORATORY (AMTL)?
CRRC Wall Licensees with their own testing facilities have the opportunity to become a CRRC Wall Rating Program Accredited Manufacturing Testing Laboratory (Wall AMTL). Wall AMTLs are able to submit radiative property data for Color Family Additional Element Applications in the Wall Color Family Program. Becoming an AMTL can also aid in demonstrating ISO 17025 compliance through participation in the biennial CRRC Interlaboratory Comparison Study. The requirements for Wall AMTLs and the Wall Color Family Program can be found in the CRRC-2 Wall Product Rating Program Manual.
To apply as a CRRC Wall AMTL, please download and complete the following documents:
- Wall Rating Program Accredited Manufacturing Testing Laboratory Application (CRRC WF-2)
- Wall Rating Program Accredited Manufacturing Testing Laboratory Agreement
Please send the completed AMTL Application (CRRC WF-2) to [email protected]. The AMTL Agreement is not due until the program opens in January 2022.
Applicants will be provided with information about completing the AMTL application process when the program is open in January 2022. Payment of the AMTL fee is not due until the program opens. The relevant fees can be found in the CRRC Wall Rating Program Fee Structure (AMTL fees on page 2).
Wall AMTL Training
Wall AMTL applicants are required to participate in a CRRC Laboratory Training and complete testing on a set of CRRC-provided specimens to demonstrate compliance with the program requirements. The first Wall AMTL Training will be held virtually in November 2021. Please contact [email protected] for more information.

CURRENT FOUNDING MEMBERS
The CRRC has been working in collaboration with industry and end users on the development of a third-party rating program for exterior wall products for the past few years. The CRRC Wall Rating Program will be similar to the CRRC’s Roof Product Rating Program, with product ratings based on the surface radiative properties of exterior wall products. The CRRC Wall Rating Program and Rated Wall Products Directory will launch on January 17, 2022.
- June 17, 2019: The CRRC membership amended the organization’s bylaws to include the rating of exterior wall products
- July 2019–August 2020: A Wall Rating Steering Committee (WRSC) of 30 members representing manufacturers, government, utilities, building enclosure experts, and other interested parties evaluated the technical aspects of the program; developed the program financial model; and conducted an initial marketing campaign to solicit interest and support. The WRSC submitted a program proposal to the CRRC Board of Directors for the approval of the Wall Rating Program
- September 24, 2020: The CRRC Board of Directors approved the Wall Rating Program
- November 12, 2020: The CRRC Board of Directors approved the roster of appointed members to the Wall Rating Program Committee (WRPC)
- September 9, 2021: The CRRC Board of Directors approved the launch date of the Wall Rating Program and program rules, including testing and weathering requirements
- January 17, 2022: The launch of the Wall Rating Program and Rated Wall Products Directory
