4 Things to Know about North American Mass Timber Standards

On-Demand Webinar

This webinar provides a comprehensive introduction to engineered wood products, with a focus on mass timber and its growing use in projects across North America. Participants will explore glue-laminated (glulam) timber and cross-laminated timber (CLT), including manufacturing processes, design specifications, and real-world case studies highlighting performance and environmental benefits. The webinar also covers the North American CLT standard (ANSI/APA PRG 320) and what it means for design professionals working with code-recognized CLT products.

What you’ll learn:

  • How mass timber — including glulam and CLT — is manufactured and specified for use in building projects

  • The performance and environmental benefits of mass timber through real-world North American case studies

  • The requirements of the ANSI/APA PRG 320 standard and how CLT compliance provides quality assurance for owners, designers, and builders

  • How code recognition of PRG 320-compliant CLT helps mitigate risk across the design and construction process

What you’ll earn

  • A downloadable certificate of completion is available after completing a brief quiz

  • Participants who complete the quiz qualify for 1 AIA HSW/LU

  • CEUs and certificate(s) received upon course completion are transferrable and may be applied towards PDHs or other general CEUs/certifications, such as PE

Offered by APA — The Engineered Wood Association.
