Frequently asked questions
Which is more durable, Western Hemlock or Kail Blue Pine?
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?
Western Hemlock — outdoor performance combines decay durability with dimensional stability, and it leads on that combination.
Is Western Hemlock harder than Kail Blue Pine?
Yes — Janka 540 lbf vs 460 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.
