|After extensive testing at UMaine, the tree is the first new species accepted for commercial and residential building in roughly 80 years.
Members of Maine’s forest products economy are hailing the certification of Norway spruce as construction lumber – the first new species to be added to the list of approved lumber in about 80 years.
The pretty evergreen with its gently sloping boughs was named to the list after five months of testing at the University of Maine. Researchers tested more than 1,300 pieces of lumber milled from Norway spruce grown in Maine, Vermont, New York and Wisconsin. On Oct. 20, the American Lumber Standards Committee approved the inclusion of Norway spruce for home construction and industrial applications.
