Siberian Larch


The wood is moderately durable and subject to insect attack. The heartwood is resistant and the sapwood moderately resistant to preservative treatment.

Mechanical Properties:

Air dried timber is about 50% harder than Baltic redwood, and slightly stronger in bending strength and toughness, and similar properties in crushing and impact strengths.


Larch dries fairly rapidly with a tendency to distort and for knots to split and loosen. It may be kiln dried very satisfactorily. There is small movement in service.


  • Pit props, posts, transmission poles, piles, boat planking, exterior work in contact with the ground
  • Door and window frames, flooring, staircases, ship building
  • As larch is harder an tougher than most conifers, it is used in preference where durability and strength are prime requirements
  • Sliced as decorative veneers
