NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

  • Mushrooms: cl 2 – durable
  • Dry wood insects: durable; distinct sapwood (risk limited to sapwood)
  • Termites: class S – susceptible
  • Impregnability: 4 – not impregnable
  • Biological risk class: 3 – out of contact with the ground, not sheltered

BOSSÉ clear is moderately durable against fungi. Dark Bossé is durable.

SAWING AND MACHINING

  • Blunting effect: quite significant
  • Teeth for sawing: stellate teeth
  • Machining tools: tungsten carbide

The silica content of G. Cedrata can be high to very high. Irritating dust.

ASSEMBLY

  • Nailing – Screwing: good hold
  • Gluing: correct

Pre-boring may be necessary for G. Thompsonii due to its hardness. Bonding G. Cedrata can be difficult due to resin exudation.
