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.
Successful performance in fire tests of three types of off-the-shelf metal connectors for glue-laminated-timber column-to-beam assemblies will make it easier for designers to get approval for GLT structural systems in buildings up to 85 ft in height, says the Softwood Lumber Board, which sponsored the tests.
Good performance of the cross-laminated timber panels, made by the first certified CLT supplier in the U.S., is expected to have a positive impact on domestic production.
