Mass timber continues to be crucial in delivering carbon-neutral and energy-efficient buildings that, as the following products attest, rise to match the demands of each project.

The project features glulam columns on a 24-foot by 32-foot grid, topped by large glulam purlins; all in support of curved rafters on 16-foot centers. The roofs sweeping curvature is achieved with laminated deck boards that reach as long as 32 feet.(Courtesy Mercer Mass Timber)CLT 3100 m3Mercer Mass TimberIn California, Google Borregas is a 5-story, 182,500-square-foot office building that uses CLT 3100 m3. The project, led by Michael Green Architecture, features 14-foot cantilevered floor plates made possible by a woodconcrete composite system that connects the CLT panels with concrete.(Courtesy Timberlab)CLT panels atop glulam columnsTimberlabA structural system of CLT panels atop glulam columns and girders was used to build Northlake Commons, a 275,000-square-foot, mixed-use project with 158,000 square feet of mass timber. This system meets one of the most strict vibration requirements in any building type, which can often be difficult to achieve with mass timber.

Almost 75 percent of the wood fiber used in the panels is salvaged from the 2020 Labor Day wildfires in Oregon, and 100 percent of the material was sourced from Oregon fiber.(Courtesy International Timberframes)Curved DLT PanelsInternational TimberframesInternational Timberframes developed curved dowel-laminated timber panels made from hand-cut wood to help better select the best notches and faces. The curved panels offer a greater variety and ease in mass timber designs that are unique to the market.
