Mass Timber From Paulownia Wood Unique Material

Paulownia wood has some properties that make it an interesting material for mass timber. The little known hardwood! What is paulownia wood?

Consider this, the paulownia tree is now grown in over 60 countries around the world to increase environmental & economic prosperity.

What is Mass Timber?

Mass timber can be produced in slabs as large as 18-feet-long by 90-feet wide and up to a foot thick. These large panels are created by layering and laminating wood boards such as pine, fir, spruce, birch, ash, and beech together so the grain of each layer faces against the grain of the adjacent layers.

Advantages of Paulownia wood for mass timber:

• Lightweight: Paulownia is one of the lightest hardwoods available, which makes it easier to transport and handle during construction.
• Fast-growing: Paulownia trees grow rapidly, making them a potentially sustainable resource for timber production.
• Stable: Paulownia wood is relatively stable and resistant to warping, shrinking, and cracking, which are important qualities for structural materials.
• Fire-resistant: Paulownia has a higher ignition temperature than other woods, making it more resistant to fire.
• Rapid regrowth: Paulownia trees can regrow from cut stumps within a few weeks, reaching a height of 15-30 feet in just one growing season.

Disadvantages of Paulownia wood for mass timber:

• Strength: Paulownia wood is not as strong as other species used for mass timber, such as spruce. This could limit its use to certain applications or require additional engineering to ensure structural integrity.
• Durability: Paulownia is relatively soft and may not be as durable as other woods in high-traffic areas or harsh weather conditions.
• Cost: Currently, paulownia wood can be more expensive than traditional mass timber materials, with increased supply, this could change as production increases.
• Availability: While paulownia grows quickly, it may not be widely available in all regions.

Paulownia Strength Compared Birch & Pine

Paulownia Mass Timber Overall:

Paulownia wood has potential as a mass timber material due to its lightweight, stability, and fire resistance. If the cost and availability of paulownia wood improve, it could become a more viable option for sustainable mass timber construction.

It's important to work with structural engineers and building professionals to determine if paulownia wood is a suitable material for your specific mass timber project.

However, its lower strength and potential durability issues may require additional engineering and careful consideration for specific applications. A sandwich approach can offer a paulownia core with a birch exterior further increasing the strength of the structure while saving weight.
