Siberian larch is becoming extremely important and valuable material in the European market. Customers highly appreciate this kind for its strength and density (650 kg/m3), marking special durability and resistance of timber to the extreme external influences. Moreover, larch differs with good colouring and structure.
The given breed is widespread almost on all territory of Russia, but only larch growing in Siberia is valued. As the climate on the European territory is softer, timber of the European larch much more friable and can be compared with the usual pine. The Siberian larch reaches
Larch timber is one of the best materials if judged by resistance to external influence. Owing to a combination of high density and high content of pitch, this breed defies rotting more then others. Kernel larch firmness twice surpasses that of oak, ash and pine, whereas sap wood is associated with the average firmness group and is comparable to a fir-tree. Thus, larch will serve
Historically, larch wood was used in elements and products intended for long exploitation at significant loadings. For many centuries larch was used for construction of bridges and moorings, erection of telegraph poles and creation of miner racks, wooden designs and ship parts. As a classical example, one could introduce the construction of city of Venice on larch piles in the
Siberian larch has a lot of potential, as in the case of highly resistant material for the production of windows and door boxes, as well as ladders and furniture. The given type of timber is widely used for floor manufacturing, mainly due to its slow pace of wearing out.
Larch has 12 shades in colour scale and surpasses in it breeds like oak, beech, ash, maple. A spectrum of painting is from light yellow up to orange and golden-brown shades. Timber has silky shine. Radial and tangential cuts remind a composition of ash-tree, but with sharper transitions from early to late timber. Siberian larch has a beautiful texture, and colour of wood does not demand furnish or additional processing.
The ecological cleanliness, the natural shine, rich scale of shades of wood and warm tones create a cosiness and healthy natural atmosphere in houses, in construction and furnish, where Siberian larch is used.
