The selection funnel
Every count is the engine’s own. Two gates eliminate species — durability and hardness.
Engineering properties
Continuous properties show Rank #N of 60. All 7 carry into the PDF report.
Qualified alternatives
Tap a row to view. Tick to compare.
Decision trace
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.
Implementation guidance
Installation and handling rules triggered by this species’ measured properties.
Scenario comparison
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.
Properties shown — durability class, hardness, density, movement, thermal conductivity and fire class — are drawn from published sources wherever available. Where a specific figure lacks a published source it is flagged in the decision confidence and treated as indicative rather than presented as a sourced value. We never present an estimate as a measurement.
