Cross-laminated timber, or #CLT as it is known in the industry, is a form of mass timber that can replace concrete with wood in construction. These buildings are faster to construct, more energy efficient, and comprised completely from #RenewableMaterials
CLTs are typically engineered as "large wooden panels, consisting of 3, 5, or 7 layers of dimensional lumber, oriented at right angles, glued together. The panels will average 8 feet tall and 38 feet long at 3 ¼ and 3 ¾ inch thickness." Using a crane, the panels are lifted into place and fitted by hand to the supporting timber frame.
