Timberlab makes first CLT panels at Oregon plant, starts certification testing

Timberlab has made its first production cross-laminated timber panels at its new plant in Millersburg, Oregon, and samples are now being tested for product certification, Jared Revay, who leads mass timber operations at the company, said in a LinkedIn post.

Specimens cut from the panels were delivered to the APA lab in Tacoma, Washington. Both Douglas fir V-grade and E-grade layups are being tested. CLT must be certified under the ANSI/APA PRG 320 standard before it can be used in buildings under U.S. codes.

The plant, built by Timberlab, a subsidiary of contractor Swinerton, is designed to make 7 million to 9 million square feet of CLT a year, or about 100,000 cubic meters. Construction began in February 2025, and the structure was completed in November 2025. Kallesoe supplied the presses and Scheuch the dust extraction systems.

Timberlab President Chris Evans said last November that within about 12 months the facility would be certified and products would be shipping. The company also bought a sawmill and planing mill in Philomath, Oregon, which it planned to restart alongside the CLT plant.
