What is Mass Timber?
Mass timber is a type of engineered wood product made from several layers of lumber boards that are glued together to create large structural elements such as columns, beams, and panels. Mass timber is a renewable and sustainable building material that is gaining popularity in the construction industry due to its many benefits, including its strength, durability, and aesthetic appeal.
There are several types of mass timber:
- Cross-laminated timber (CLT). CLT is the most common type of mass timber and consists of several layers of lumber boards stacked perpendicular to each other and bonded with adhesive.
- Nail-laminated timber (NLT). NLT is similar to CLT but is made by nailing the layers of lumber boards together instead of using adhesive.
- Dowel-laminated timber (DLT). DLT is similar to NLT but uses wood dowels to join boards instead of nails or screws.
- Glue-laminated timber (glulam). Glulam is made by gluing several layers of lumber boards together in parallel, creating a strong and durable beam or column.
Mass timber has several advantages over traditional building materials such as concrete and steel. It is lightweight, yet strong and durable, and can be used to build tall buildings without the need for a steel or concrete core. Mass timber also has a lower carbon footprint than traditional building materials, as the production process generates less greenhouse gas emissions. Additionally, mass timber is easy to work with and can be cut and shaped on-site, allowing for faster construction times.
In recent years, mass timber has become increasingly popular in the construction industry, with several tall buildings being constructed using this material. The use of mass timber is expected to continue to grow as more architects and builders recognize the benefits of this sustainable and innovative building material.

Cross-laminated timber (CLT)
Cross-laminated timber (CLT) is a wood panel system that is rapidly gaining popularity in the U.S. after being widely adopted in Europe. The strength, dimensional stability, and rigidity of CLT allow it to be used in mid- and high-rise buildings.
NAIL-LAMINATED TIMBER (NLT)
Nail-laminated timber (NLT or nail-lam) is a century-old construction material that is undergoing a design renaissance. Its structural performance and design elegance come together to create inspiring spaces in many historical buildings as well as modern new projects of all sizes.
DOWEL-LAMINATED TIMBER (DLT)
Dowel-laminated timber (DLT) is common in Europe and is gaining traction in the U.S. for its ease of use with computer-controlled (CNC) machinery—such as lathes, routers and mills—and its all-wood composition. DLT is similar to nail-laminated timber (NLT). Instead of nails or screws, however, DLT uses wood dowels to join laminations.
GLUED-LAMINATED TIMBER (Glulam)
Glued-laminated timber (glulam) is a structural engineered wood product commonly used for beams and columns in residential and commercial applications. It is a highly visible form of mass timber in contemporary projects, with long spans framing signature designs left exposed to take advantage of wood’s natural aesthetic.
