Recommendation
Choose Western Hemlock if…
- Roof decking, laminating stock, mouldings and architectural trim, general construction where the higher hardness, bending strength and stiffness are what the piece must deliver and the shared Class 4 durability and Class C fire class are the baseline
- Doors and windows, joinery, flooring, veneer and plywood where the documented Western Hemlock role is what the project is specifying
Choose Kail Blue Pine if…
- Internal fittings of houses — planking, door and window frames, panels — where the working properties are sufficient and the documented Himalayan pine role is what the project is specifying
- Furniture, camp furniture and drawing boards (after treatment) and packing cases where cost or the resinous character of the timber is the working consideration
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 work the separation is movement, not decay: Kail Blue Pine moves 5.2% tangentially against 7.8%, which decides board width and fixing spacing more than the durability class does.
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. The Library Scores are percentile ranks against the other 59 species we cover — durability and stability carry the most weight, and no price data enters the calculation. Full weighting and what it excludes.
