Mass Timber- A Durable Choice

Recent developments in wood technology have generated a range of mass timber products that are strong, durable, and fire-resistant. The versatility and strength of mass timber products continue to draw the attention of architects, builders and industry partners across North America.

Wood’s natural flexibility and toughness make it a resilient building material, capable of providing centuries of durability. One reason behind this is that timber can absorb and release moisture from the air and is resistant to many of the conditions and chemicals that can harm steel and concrete. Coupled with quality design and routine maintenance, mass timber structures can have an astonishingly long service life.

A study from Wood and Fiber Science in 2019 noted that a cross-laminated timber (CLT) structure withstood over 90 minutes of burning before the loss of integrity. In contrast, a single-story wood frame home in the same study only withstood 17 minutes before the collapse. The reason behind mass timber’s remarkable fire resistance lies in how it reacts to flames. When exposed to fire, it forms a layer of char on the surface. This char layer creates an insulator for the core, protecting it from the flames. This attribute makes mass timber a safe choice for homes and mid-rise apartments because it allows the occupants much more time to escape in the event of a fire.

In 2007, a team of Japanese and Italian scientists used a ‘shake table’ to test a seven-story CLT building. The results showed it could withstand the equivalent seismic forces of the 1995 earthquake in Kobe, Japan. Since mass timber elements are flexible, lightweight, and strong, they’re less affected by side-to-side seismic motion than similarly sized steel or concrete structures.

When building your next project, it’s important to consider the durability and resilience of your materials. Using mass timber adds strength and safety. At the same time, wood’s natural qualities make it a visual joy. Cornerstone Timberframes is proud to offer mass timber frames built to last generations.

Mass Timber – A Construction Revolution for 2023

Mass Timber – A Construction Revolution for 2023

Considering construction trends and consumer interests in 2023, mass timber will be at the forefront of innovative and sustainable construction this year. Its strength, durability, and beauty have already captured the attention of architects and industry leaders in Europe, North America and Asia. Its popularity will only grow as more customers ask for sustainable building materials.

What is Mass Timber?

Mass timber (short for ‘massive timber’) is a building material that joins layers of timber together with glue, dowels, or nails to form a single product. A variety of products fall under this label. For example, cross-laminated timber (CLT) is made by layering timber boards crosswise at 90° angles and gluing them into place. The strength and versatility of these materials allow them to span farther and be used as columns, beams, floors, building envelopes, and demising walls.

On The Rise.

Over the past decade, mass timber has seen extreme growth in demand. In 2015, global mass timber production only reached 500,000 m³. Since then, production has skyrocketed. In 2020, global production reached 2.8 million m³; more than 40% year-on-year growth. Considering these rates, mass timber could account for 0.5% of all new urban buildings by 2050, an impressive feat for a relatively new material.

Why is it So Popular?

Although once considered an emerging building technology, mass timber has quickly gained wider market acceptance. This is due mainly to the urgent need for low-carbon buildings. “Wood sequesters carbon,” reports Kristen Mosier, “removing it from the atmosphere and storing it.”

Mass timber allows architects and designers to reduce their building’s carbon footprint without sacrificing quality.
Mass timber products perfectly combine safety, beauty, affordability, and durability. It’s no wonder why they’re at the forefront of sustainable construction.

At Cornerstone Timberframes, we are proud to work with mass timbers and the design ideas that are changing how we build. Interested in mass timber for your project? Reach out to us by phone at (204) 377-5000 or email us at info@cstf.ca.
