PHYSICAL AND MECHANICAL PROPERTIES

These properties can vary significantly depending on the origin and growing conditions of the wood.

• Density *: 0.72
• Monnin hardness *: 5.2
• Coef. Volume shrinkage: 0.48%
• Stability in service: stable
• Total radial shrinkage: 4.0%
• Fiber saturation point: 25%
• Total tangential shrinkage: 7.0%

(*: 12% humidity)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

• Mushrooms: cl 2 – durable
• Dry wood insects: durable heartwood but indistinct sapwood
• Termites: class D – durable
• Impregnability: 3 – slightly impregnable
• Biological risk class: 3 – out of contact with the ground, not sheltered

The possible presence of poorly differentiated sapwood in the flows may influence the expected durability.

SAWING AND MACHINING

• Blunting effect: normal
• Teeth for sawing: ordinary or alloy steel
• Machining tools: ordinary

Possible difficulties in planing due to the counter grain.

ASSEMBLY

• Nailing – Screwing: good hold
• Gluing: correct

Pilot holes sometimes necessary in particular for small dimensions

USES

Use this wood at a humidity level lower than that generally recommended for the intended use.

REACTION TO FIRE

• French conventional classification: thickness> 14 mm: M.3 (moderately flammable) thickness <14 mm: M.4 (easily flammable)
• classification according to euroclasses: D s2 d0 This default classification concerns solid woods meeting the requirements of standard NF EN 14081-1 appendix C (May 2006), used in vertical walls. Namely structural wood, classified, with a minimum average density of 0.35 and a minimum thickness of 22 mm.
