Siberan Larch

About Larch

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.
