Scientific name: Intsia spp

Geographic origin: Southeast Asia and Oceania


  • Sapwood: light yellow with greenish light shades
  • Heartwood: orange brown when it is fresh wood that varies from light to dark bronze colour with the lights effects.
  • Fiber: Straight. Slightly intertwined fibers are very frequent..
  • Grain: medium size to rough

Capacity of being impregnated

  • Sapwood: Capable of being impregnated
  • Heartwood: No capable of being impregnated


  • Sawing process: the hardness and high silica contents wear away tools and so makes sawing process difficult. In addition to that, oils can also produce irritation.
  • Drying process: From low to very low speed. Little risk of deformation and crack formation.
  • Planing process: Appart from hadness and silica difficulties, risk of repelling is very frequent due to the intertwined fibers.
  • Gluing process: No difficulties arise excepting on very oily surfaces. In these cases, previous cleaning can be required.
  • Nailing and screwing process: Pre-drilling is required
  • Finish: No difficulties
