Mass Timber and CLT Construction: The Wood Structure System Expanding Into Taller Commercial Buildings

Mass timber construction — CLT (cross-laminated timber), glulam, NLT, DLT — has moved from European specialty into mainstream North American commercial construction. IBC 2021 authorizes Type IV-A/B/C construction up to 18 stories. Mass timber offers distinctive aesthetics, faster erection, and carbon benefits. Coordination specifics differ substantially from steel or concrete structures.
