Within the relatively recent past, we have improved our ability to obtain longer pieces of wood that have sufficient strength and meet building codes, allowing for taller and larger buildings to be built. Over the past 40 or 50 years, we have greatly enhanced techniques to produce extended lengths and widths of wood that possess structural characteristics similar to the more conventional steel and concrete products such as greater spans, load-bearing capacity, precision, and predictability. These improvements allow us the ability to build taller, larger, and more complex wood products, often referred to as “mass timbers.” One type of mass timber that is gaining popularity is cross-laminated timber, commonly referred to as CLT.
