Siberian Larch

Siberian Larch of Izbarus

Siberian larch is a unique creation of nature. At the base, this tree may reach the diameter of 2.5 m,  and 50 m in height. Age of commercial wood is 700-1000 years, and in some areas there are trees older than 1300 years.

Larch can be found all over Russia, but only the larch growing in Siberia is much valued. It has large, tall straight trunks with low knottiness. Since the European climate is milder, larch wood there is much looser and is comparable with common pine.

In the Irkutsk region, from where the material for Izbarus houses is delivered, harsh winters and short vegetation period (approximately 2 months) make larch wood dense and solid.

Main properties of the Siberian larch

STRENGTH
All strength parameters of the larch wood are 30-60% higher if compared to pine. In addition, due to the special composition of resin, larch only grows stronger with time. Larch timber in its strength is comparable to oak wood. Hardness of larch - 109 units, of oak - 110 units (as per Brinnel's scale).

FIRE RESISTANCE
Fire resistance of larch wood, according to findings of the research conducted by Moscow State Forest University, is about twice higher than that of pine wood.

DURABILITY
Larch does not get rotten and does not turn blue, because presence of gum (natural substances) that protects the wood against natural deterioration.

Why Siberian larch does not turn blue?

Larch has the unique composition of resins, which inhibits formation of practically all kinds of fungi (molds).

Thanks to the peculiarities of the resin impregnating its wood, larch is not affected by rodents, wood-engravers, humidity and even salt water. Siberian larch can stand in water up to a thousand years. Now, judge it by yourself.

They are made of Siberian larch:

  • piles on which the gorgeous city of Venice stands,
  • Decembrists' houses in Irkutsk,
  • underwater foundations of the old houses (15-18 centuries) in Amsterdam.

THERMAL CONDUCTIVITY
Siberian larch provides for good thermal insulation. Volumetric heat capacity of larch wood is higher than that of pine wood. This means that a house made of larch correspondingly has more accumulated heat. This manifests itself in the fact that, during the heating period, the temperature in the heated rooms is more evenly distributed in the house throughout the day (the house cools down more gradually), and in the heat of the summer there remains a sense of coolness.

BEAUTY
Natural wood of larch in the interior is unique due to the richness of its natural texture, and brings special warmth to the house. Here are just some of its aesthetic characteristics:

  • natural shine (because of high gummosity)
  • warm colors and rich range of wood shades (from amber to soft burgundy)
  • annual rings are clearly expressed and are well seen on all cross-sections of wood.

So, there is no need to "strengthen" the wooden texture of larch with paint.
