Every count is the engine’s own. Two gates eliminate species — durability and hardness.
Continuous properties show Rank #N of 60. All 7 carry into the PDF report.
Tap a row to view. Tick to compare.
Gate first, then ranking by priority.
Exterior decking, outdoor uncovered, heavy traffic → needs EN 350 Class ≤ 2 and ≥ 1,300 lbf Janka.
26 of 60 species fail the durability class or hardness floor and are removed.
The 34 survivors are ordered by your priority, then durability and hardness.
Lignum Vitae — highest durability class and hardness among the qualifying woods.
Installation and handling rules triggered by this species’ measured properties.
Change one project input below. The engine runs a second analysis and shows you exactly why the recommendation changed — or honestly tells you it didn’t.
Every property shown — durability class, hardness, density, movement, thermal conductivity and fire class — is a sourced published value, not an approximation. Where a specific figure lacks a published source it is flagged in the decision confidence. We never present an estimate as a measurement.
Durability of wood and wood-based products — natural durability classification of solid wood.
Wood Handbook: Wood as an Engineering Material (FPL-GTR-190).
Species mechanical and physical property records — hardness, density, movement.
Plant Resources of South-East Asia — timber volumes for regional species data.
Design preview of the V3 experience — the full project workflow, live requirement engine, comparison and package. Figures are representative real values; production computes every value live from the 60-species engine and preserves all logic, evidence and SEO. No invented prices, service-life claims, confidence scores or ratings.
