Based on recent fire test results, mass timber groups have adjusted product certification standards to require the use of cross-laminated timber with structural adhesives tested to demonstrate better fire performance.
Though the new CLT standards are not going to be published and adopted by jurisdictions until 2021 or later, wood interests are “actively” working with adhesive suppliers and CLT manufacturers to implement the new requirements in the next few months, according to Borjen Yeh, technical services director for APA-The Engineered Wood Association.
