REACTION TO FIRE

  • Conventional French classification :
    – thickness > 14 mm: M.3 (moderately flammable)
    – thickness < 14 mm: M.4 (highly flammable)
  • Classification according to Euroclasses: D s2 d0

This default classification applies to solid wood meeting the requirements of standard NF EN 14081-1 +A1 (August 2019). used in vertical walls. In other words, classified structural timber with a minimum average density of 0.35 and a minimum thickness of 22 mm.
