- organic material benefits
- 01 organic material benefits
- 01 Durability Class 1 per AS 5604 but rated for above-ground use only without preservative treatment — in-ground contact requires H4/H5 treatment
- 02 High density (~900–1100 kg/m³) makes long boards heavy for cladding; boards over 3.6 m typically require two-person handling
- 03 Premium supply cost $80–180/m² installed — approximately 2–3x the cost of equivalent pine cladding profiles
- 04 Tangential shrinkage ~8–10% means only seasoned timber (MC <15%) per AS/NZS 2796 is suitable; green timber risks significant movement and cupping
- 05 High Janka hardness (9.1 kN) makes machining and nail-driving difficult — carbide-tipped tooling required; standard HSS blades blunt rapidly
