CLT in the US: Manufacturing and Applications

National Partner: DR Johnson

Architects around the world are using mass timber construction systems to build taller wood buildings, incorporate the aesthetic of exposed wood, or increase the amount of prefabrication on their projects. Many use cross-laminated timber (CLT) panels and glue-laminated timber (glulam) beams as the building structure, often as a carbon-friendly alternative to conventional materials such as steel, masonry and concrete. In this presentation by an Oregon-based CLT manufacturer, successful US projects will be highlighted to demonstrate the variety of commercial and multi-family applications available for CLT under today’s building codes. Topics will also include CLT manufacturing, benefits such as structural versatility, and potential future uses.

Founded in 1951, DR Johnson is a second-generation, family-owned wood products manufacturer located in Riddle, Oregon—the heart of Oregon’s timber country. An affiliated company, Riddle Laminators, was built at the same location in 1967 to manufacture glue-laminated timber beams. Going forward, both the glulam beams and cross-laminated timber panels will be manufactured and sold under the business name DR Johnson Wood Innovations.

MORNING SESSION 9:45 AM

Correcting Misperceptions of CLT Fire Performance

David Barber, Arup

This presentation aims to answer questions commonly asked about CLT fire performance, including delamination and fire-resistance ratings, and how these issues relate to low- and mid-rise buildings within the size limits of the current IBC vs. high-rise buildings. Because CLT is relatively new in the US, designers often have to explain the fire design of their structure in much more detail than is required for typical construction materials, even for code-compliant buildings. This session should equip designers with a better understanding of the code requirements, relevant and applicable CLT design methods, test standards and available testing related to CLT fire performance.

David is a Principal with Arup, based in Washington, DC, where he works as a fire protection engineer. He has been involved in the research and design of timber structures for over 20 years, assisting with testing and development of new timber technologies, authoring fire safety design guides for construction, working with wood product suppliers and completing fire safety design for mid-rise and high-rise timber buildings.

Knock on Wood: Acoustical Solutions in Mass Timber Structures

Denis Blount, CTS-D, Arup

The use of mass timber in multi-family and commercial buildings presents a complex set of acoustic challenges. While laboratory measurements of the impact and airborne sound isolation of traditional building assemblies, such as concrete, steel, and light wood-frame, are widely available, fewer resources exist that quantify the acoustic performance of mass timber assemblies, including CLT and NLT systems. Furthermore, acoustical professionals are not typically retained for mass timber projects, placing the acoustic responsibilities on the design team. This presentation will review common mass timber assemblies and acoustical rules of thumb for architects and designers. Topics will include detailing strategies, options for eliminating flanking paths, and best-practices for achieving good acoustic performance in mass timber buildings.
