TechNote 23 Cross Laminated Timber (CLT)  


Cross laminated timber (CLT) is an engineered wood building system used to complement light‐and heavy‐timber framing options. Layers of lumber are laminated together in alternating directions to form a solid wood panel with high strength and dimensional stability.  Manufactured panels are typically 8’ to 10’ wide, up to 20” thick, and up to 64’ long.  75% lighter than concrete, they can be used as an economical alternative to concrete slabs, masonry and steel in many building types. The manufacturing process has been standardized, but the panels are fabricated as needed to custom dimensions.
