Common Name(s): Siberian Larch Scientific Name: Larix sibirica Distribution: From near the Finnish border
east to the Yenisei valley in central Siberia Average Dried Weight: 36 lbs/ft 3 (575 kg/m 3 )
Janka Hardness: 740 lb f (3,290 N) Shrinkage: Radial: 4.2%, Tangential: 8.2%, Volumetric: 12.5%, T/R Ratio: 2.0 Color/Appearance: Light reddish to golden brown. Narrow
sapwood is nearly white and is clearly demarcated from
the heartwood. Flatsawn sections can exhibit a lot of
character and interesting patterns in the growth rings. Grain/Texture: Grain is generally straight with few knots.
Texture is medium to fine with a greasy or oily feel.
Rot Resistance: Very durable regarding decay resistance. Workability: Most hand and machine operations produce
good results. However, natural resins in the wood have
a tendency to gum up saw blades. Also, because of the
disparity between the soft earlywood and the hard latewood,
sanding can create dips and uneven surfaces.
Odor: Siberian Larch has a distinct resinous odor when being
worked. Allergies/Toxicity: Although severe reactions are quite
uncommon, wood species in the Larix genus have been
reported to cause skin irritation, as well as hives and skin
lesions. Pricing/Availability: Siberian Larch is used
for construction lumber, particularly siding / cladding and
decking. Prices should be moderate within its local range. Common Uses: Veneer, utility poles, fence posts, flooring,
boatbuilding, and construction lumber. Comments: Even though Siberian Larch is a conifer, it is
deciduous and loses its leaves (needles) in the fall.
Ammonia fuming larch produces a darker colored wood
surface; “fumed larch” veneer is sometimes used as
a decorative veneer.
