What is Cross Laminated Timber?

cross laminated timber

Developed in Europe in the 1990s, CLT technology is slowly gaining a foothold in North America as gains are made in fabrication. Cross laminated timber walls are constructed from small pieces of wood that have been joined together using glues, hardware, or wood joinery. Large planks of wood can also be used by butting them together into sheets that are then laminated at 90 degrees to each other. Typical panels consist of three, five or seven layers of dimensional boards. Using these methods, panels of almost any size can be created.

Mass Timber Workshop 2019

Background: Twenty-four industry professionals attended Utah’s first Mass Timber Workshop on September 5, 2019 in Heber City, Utah. This workshop included presentations on mass timber from forest to frame, beginning with a discussion of sustainable forest management and the positive impact of regionally-sourced materials on Utah communities. It covered design topics related to codes and applications, fire resistance, and wind and seismic resilience, the use of wood in USU Botanical Center, and legislative efforts to further mass timber in the state. Attendees gained a top to bottom understanding of the status of mass timber in Utah and beyond, and left with the design knowledge needed to pursue a mass timber project. This workshop was sponsored by WoodWorks Wood Products Council.
