Abstract/ Summary

Cross-laminated timber (CLT) is an engineered wood product made of three or more orthogonally bonded layers of lumber that are glued together with structural adhesives to form a panel intended for roofs, floors, or walls.

Currently, there are no CLT manufacturers in the Northeastern U.S. despite the region having vast forestlands of commercial softwood timber. Sitting atop one of the planet’s largest population centers, Maine is the region’s primary wood basket, the most heavily forested state in the nation (as a percentage of land area) containing over 27 billion cubic feet of wood, i.e., live trees, on its forest land (USDA Forest Service, 2002). For CLT manufacturing in the Northeast, spruce-pine-fir-south (SPF-S) is the target grouping, with five major sawmills in the region producing 500 MMBF of dimensional lumber each year.
