Brea, Calif. — The ICC Evaluation Service (ICC-ES) and APA – The Engineered Wood Association (APA) released their first joint evaluation report for cross-laminated timber products (CLT). This program certifies CLT products for compliance with ICC-ES Acceptance Criteria for Cross-Laminated Timber Panels for Use as Components in Floor and Roof Decks (AC455) and ANSI/APA PRG 320 Standard for Performance-Rated Cross-Laminated Timber. The joint evaluation report, ESR-3631, was issued in September 2018 to Structurlam Mass Timber Corporation for its Structurlam CrossLam CLT panels.

Verifying that the CLT panels are in compliance with building, residential, and green codes and standards, ESR-3631 also provides information about the acceptance criteria used to evaluate the product and how the product should be identified and installed. The evaluation report authorizes Structurlam to add the ICC-ES mark of conformity to their product packaging and identification, and the company may now list their panels as certified by ICC-ES and APA.

“As experts in product evaluation and certification, we take immense pride in the research behind our evaluation reports,” said ICC-ES President Shahin Moinian, P.E. “We evaluate cutting edge products and technology in the built environment quickly and efficiently. We are pleased to be working with the experts at APA to verify the highest quality and safest CLT products in the market today.”

“APA is pleased to collaborate with ICC-ES in offering CLT manufacturers with the high-quality joint evaluation reports that support the cross-laminated timber used in the demanding mass timber construction,” said Dr. BJ Yeh, P.E., director of the Technical Services Division at APA.

Manufacturers may apply separately to ICC-ES for a product listing under the new Product Listing Program. For more information about the ICC-ES Product Listing Program, visit https://icc-es.org/evaluation-report-program.
