Frequently asked questions
Which is more durable, Hem-Fir 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?
Hem-Fir — outdoor performance combines decay durability with dimensional stability, and it leads on that combination.
Is Hem-Fir harder than Kail Blue Pine?
Yes — Janka 500 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.
