What is mass timber?

An overview of mass timber products and their applications, providing detailed descriptions of CLT, glulam/GLT, DLT, NLT, SCL, and timber-concrete composite systems. Covers product characteristics, typical dimensions, manufacturing processes, code paths, and applications for each mass timber type. Explains hybrid system benefits combining mass timber with other materials, sourcing guidance through manufacturer directory, and resource access for design and construction teams. Includes product-specific code references (ANSI/APA PRG 320 for CLT, ANSI 190.1 for glulam, etc.) and practical information about dimensional ranges, species options, and manufacturing capabilities. Features project examples and visual references for each product category.
