A new kind of engineered lumber is being tested at the University of Maine. This new “plywood on steroids” could compete with other construction materials like concrete and steel, and this new industry may help add value back into Maine’s forests.
“It would be a new market, it would be a new factory, sort of like making furniture, except it’s really big pieces,” said Steve Shaler, director of the School of Forest Resources at UMaine.
The new market would be for cross laminated timber, an engineered plywood created and tested at the University of Maine. CLT is made with different types of wood from Maine’s forests. It’s then pressed into a strong construction material, ready to use at construction sites.
“They come out as large panels, solid panels with windows and door openings pre-cut, maybe utility locations pre-cut, and they’re swung into place and connected together and they go up very very quickly with very little cutting on site, very little waste on site,” said Bill Davids, professor and chair of the Department of Civil and Environmental Engineering.
“This is for taller structures, four stories, 10, there are buildings now that are made out of wood that are 10 stories tall,” said Shaler. The blocks of spruce, pine and fir were stress tested and broken under 10,000 pounds of force, which is stronger than normal lumber, but lighter than other building materials like steel and concrete.
