OSU & D.R. Johnson Work Together To Produce Cross-Laminated Timber

Thanks to a partnership with the Oregon State University College of Forestry, D.R. Johnson Wood Innovations in Riddle, Oregon, recently became the first U.S. certified manufacturer of cross-laminated timber.

Cross-laminated timber (CLT) is a massive structural composite panel product usually consisting of three to nine layers of dimensional timber arranged perpendicular to each other, much like layers of veneer in plywood and can be used as prefabricated wall, floor and roofing elements in residential, public and commercial structures. It is extremely strong and flexible, making it resilient to seismic activity.

Lech Muszyński, assistant professor of wood science and engineering, first saw CLT in production during his 2009 sabbatical in Austria. He says those facilities were unlike anything he had ever seen.

“I decided to visit as many as I could because the diversity was astounding,” Muszyński says. “I learned that you don’t need to be a big operation to make a difference in the market.”

Once back at OSU, Muszyński began making the rounds to industry partners to gauge their interest in constructing CLT test panels. He had little success until a meeting of the college’s Board of Visitors. Valarie Johnson, president of D.R. Johnson Lumber was in the room.
