Cross Laminated Timber’s Role in North American Construction


Published on

In the context of wood-based building systems, cross laminated timber has a unique position. This presentation from the first US CLT Symposium examines the role of CLT, mass timber and other wood building systems in North American construction. It also provides an overview of the newly released US version of the CLT Handbook, available at
