Frequently asked questions
Which is more durable, Balau or Shisham Sissoo?
Neither — both carry the same EN 350 rating (Class 2, 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 Balau harder than Shisham Sissoo?
Yes — Janka 1700 lbf vs 1660 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.
