Advantages & limitations
Paulownia
Advantages
- Very low movement in service
- Easy to machine, glue and fasten
- Lightweight — easy handling and installation
Limitations
- Not durable outdoors untreated (Class 4)
- Soft surface — dents under point loads
Bamboo Structural Engineered
Advantages
Limitations
- Not durable outdoors untreated (Class 4)
- Noticeable seasonal movement — allow for it in design
Recommendation
Choose Paulownia if…
- You need minimal movement (doors, decking, panelling)
Choose Bamboo Structural Engineered if…
- You need the harder wear surface
- Its profile matches the application better than a single overall score
Frequently asked questions
Which is more durable, Paulownia or Bamboo Structural Engineered?
Neither — both carry the same EN 350 rating (Class 4, Slightly Durable). For outdoor decisions between them, weigh dimensional stability and hardness instead.
Which wood is better for outdoor use?
Paulownia — outdoor performance combines decay durability with dimensional stability, and it leads on that combination.
Is Paulownia harder than Bamboo Structural Engineered?
No — Bamboo Structural Engineered is harder (Janka 1380 vs 300 lbf).
How we score. Each wood gets a weighted composite of the verified figures shown above: durability 22%, stability 18%, hardness 12%, bending strength 12%, machining ease 12%, stiffness 8%, flame spread 8%, lightness 8%. The Library Score is that composite's percentile rank within our 60-species library — 50 means the library median, 90 means it outperforms nine of every ten species we cover. No price data is scored — cost guidance is qualitative. The score summarises the data; it does not replace judgement about your specific application.
