Perkins+Will senior sustainable building adviser Rebecca Holt shares insights from the inaugural design and construction guide for the mass-timber product.
Enticed by the aesthetic, sustainability, and versatility of engineered wood, architects, building owners, and developers continue to express interest in mass timber design and construction in the United States. Nail-laminated timber (NLT) is one of the simplest and most accessible products in the growing family of engineered wood products, which also includes cross-laminated timber, glue-laminated timber, and dowel-laminated timber. As its name suggests, NLT consists of stacked dimension lumber nailed together to create a multilayered construction material.
One would be hard-pressed to find a designer in the U.S. who knows more about NLT than Rebecca Holt, a senior sustainable building adviser and associate based in the San Francisco office of Perkins+Will. As co-editor of the first U.S. Nail-laminated Timber Design and Construction Guide, released last May, Holt offers design guidelines and considerations for architects pursuing NLT in their projects. She was also the lead author of the 2014 Survey of International Tall Wood Buildings, which consolidated testimonials and experiences from architects around the world who have worked on high-rise timber structures.
In this podcast episode, Holt shares the benefits of NLT as well as what developments are on the horizon for mass-timber construction in the U.S. since the landmark 2014 survey.
