Advantages & limitations
Ebony
Advantages
- Rated for exterior exposure (EN 350 Class 1)
- Very low movement in service
- Hard wear surface, dent-resistant
- Best flame-spread class (E84 Class A, indicative)
Limitations
- Hard on tooling; pre-drilling recommended
- Heavy — consider structure and handling
Jarrah
Advantages
- Rated for exterior exposure (EN 350 Class 1)
- Very low movement in service
- Hard wear surface, dent-resistant
Limitations
- Hard on tooling; pre-drilling recommended
- Heavy — consider structure and handling
Recommendation
Choose Ebony if…
- You want the stronger all-round engineering profile
Choose Jarrah if…
- Weight matters — ceilings, wall panels, transport
- Its profile matches the application better than a single overall score
Frequently asked questions
Which is more durable, Ebony or Jarrah?
Neither — both carry the same EN 350 rating (Class 1, Very Durable). For outdoor decisions between them, weigh dimensional stability and hardness instead.
Which wood is better for outdoor use?
They are closely matched outdoors — durability and stability come out almost level. Let the application decide: harder surface for decking traffic, lighter weight for cladding.
Is Ebony harder than Jarrah?
Yes — Janka 2430 lbf vs 1910 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.
