Mass Timber
We are advancing mass timber construction by modernizing building codes and accelerating adoption of innovative wood products like cross-laminated timber (CLT) as sustainable alternatives to concrete and steel.
What is Mass Timber and Why Does It Matter?
Mass timber refers to a family of engineered wood products, such as cross-laminated timber (CLT) and glue-laminated timber (glulam), that are used to construct buildings, bridges, and other structures. By combining layers of wood into strong, durable building materials, mass timber is a faster, more efficient, and lower carbon alternative to concrete and steel.
Supporting Mass Timber Growth
For more than a decade, the Endowment has worked with partners to advance mass timber adoption across the United States. These collaborations helped inform the adoption of building code provisions for taller timber structures. This work included extensive fire and structural testing, technical research, and education efforts that helped demonstrate the safety, performance, and market potential of mass timber construction.
The Endowment also supports efforts to strengthen mass timber supply chains and expand market opportunities across the value chain. Through partnerships and initiatives such as the Softwood Lumber Board’s Mass Timber Accelerator Program, the Endowment helps support funding, technical assistance, and educational resources that enable developers, architects, engineers, and project teams to advance mass timber buildings from concept to construction. The program has supported projects in cities including Boston, New York City, Atlanta, Portland, and Santa Monica, helping expand awareness, local expertise, and adoption of mass timber construction.
