07 Assessment
Advantages
- Uses 20% less wood than CLT for equivalent performance
- Superior dimensional stability compared to solid timber
- Predictable structural performance through grading
- Carbon negative - stores approximately 835 kg CO₂/m³
- Excellent seismic performance with high ductility
- Available in large panel sizes (3.6m × 14.6m)
- Multiple structural grades available (F10, F16)
- 100% recyclable at end of life
Constraints
- Not manufactured in Australia - import only
- No Australian Standards compliance testing completed
- Single global manufacturer (monopoly supply risk)
- Requires specialist mass timber connections
- Combustible material requiring fire engineering
- No local technical support available
- Import costs and lead times significant
- Requires weather protection during construction
