Because of its strength and inherent fire resistance, mass timber offers an alternative to fossil fuel-intensive materials for many applications—including high-rises—and an opportunity to reduce the carbon footprint of the built environment. Often associated with Type IV buildings, mass timber can be used in any construction type that allows wood structure. The mass timber family of products includes cross-laminated timber (CLT), nail-laminated timber (NLT), dowel-laminated timber (DLT), glue-laminated timber (glulam or GLT), and some types of structural composite lumber (SCL). Learn how to efficiently design and construct these buildings, while creating innovative projects with significant market appeal.
