Over the past couple of decades, the construction industry in America has begun incorporating a structural material that is both old and new: mass timber. As this building technology has proliferated, New Energy Works has evolved alongside it and incorporated mass timber into our work. We’re obviously huge fans of building with wood for a wide variety of reasons. Now with mass timber, there are more possibilities than ever. Here’s what it is, why it matters, and why so many architects and developers are embracing it.
What Is Mass Timber?
Mass timber refers to a category of engineered wood products made by bonding layers of wood together to create large, solid structural panels, beams, and columns. Unlike traditional “stick framing,” which uses small pieces of lumber assembled on-site, mass timber components are manufactured in a controlled environment and delivered ready to install.
Common mass timber products include:
- Glue-Laminated Timber (Glulam) – Beams or columns formed by gluing together layers of lumber with the grain aligned in the same direction. Glulam members can be straight or curved.
- Cross-Laminated Timber (CLT) – Large panels made by layering boards in alternating directions and bonding them with structural adhesives.
- Nail-Laminated Timber (NLT) and Dowel-Laminated Timber (DLT) – Panels assembled using nails or hardwood dowels instead of adhesives.
- Mass Ply Panels (MPP) – Similar in concept to common plywood, these panels are built out of many layers of wood veneer and adhesive.
These products create structural elements that rival steel and concrete in strength and stability, while offering unique architectural and environmental advantages.
