What is Mass Timber?

Mass timber is a category of engineered wood products such as cross-laminated timber (CLT), glue-laminated timber (glulam), and nail-laminated timber (NLT) - that are manufactured by bonding layers of wood together to create strong, structural panels and beams. These large-format wood components can replace steel and concrete in many mid- and high-rise buildings, offering comparable strength and fire performance while significantly reducing embodied carbon.

Because wood stores carbon and is renewable when responsibly sourced, mass timber is often used in sustainable construction strategies focused on lowering a building’s overall environmental impact.
