≈ approximate = a figure for the trade group or plantation-grown timber, not a test result for this species itself · MC = moisture content at testing · Real values vary with the source of the timber, its age and how it was kiln-dried
Durability and working properties
- Durability
- Moderately durable · prone to insect attack · resinous
- Machining / working
- Workable, but silica and resin interfere with tooling · considerable movement in service
Sustainability and sourcing
Yang Na grows and is planted in Thailand. Using timber with a traceable local source keeps transport short and helps protect trees in natural forest.
WisutWood uses legal timber, can issue sawn-timber control documents, and kiln-dries to 12% moisture content or less, so the woodwork lasts and does not have to be torn out and replaced.
