Siberian Larch timber is a species of tree grown in arctic conditions and under much duress, although Larch grows faster than most coniferous trees from the same area. Native to western Russia, it is a timber that is held in high esteem by the timber trade and used predominantly for construction work as a hardy cladding material. It carries much natural resin and is especially resistant to decay . It is extremely hard making it one of the toughest and
strongest softwoods in the world.
Properties
Siberian Larch Drying Difficult to dry due to its high resin content. Therefore it should be dried slowly to prevent checking and other drying defects. Strength Likely to be similar to European larch which is about 50% harder than Scots pine and slightly stronger in bending and toughness. The strength values for slow grown Larch material are likely to be slightly higher than for faster grown plantation sourced material. Working Qualities Similar to European larch in that it saws, machines and finishes well but it tends to split on nailing and therefore drilling is ecommended particular at board ends.
Durability
Durable. The heartwood is moderately resistant to preservative treatment and the sapwood is permeable. Especially resistant to decay.
Treatability
Extremely difficult
