Making the most of this renewable resource, cross-laminated wood makes lumber even greener. Dimensional timber is stacked on top of one another perpendicularly to create this material.

A steel-framed building that has suffered significant damage frequently has no choice but to be completely torn down and rebuilt. On the other hand, workers may dismantle a single portion of a CLT construction, saving time, energy, and resources.
