DECKING & FLOORING
Grows in a Harsh Climate – Siberian Larch can reach a height of 25m to 40m and a diameter of 60cm or more. The tree grows in the East and partly in Western Siberia (Lake Baikal area). The climate in which Siberian Larch grows is defined as extreme continental, meaning short hot summers and long cold winters. The area in Siberia in which our larch is grown has an average temperature in January of 5 degrees Fahrenheit and in July it is 64 degrees Fahrenheit. This harsh climate gives Siberian Larch its unique qualities as a superior building material.
Durability. Latewood is denser and mechanically better than the earlywood. This higher proportion of latewood equates into a more naturally durable wood. Siberian Larch wood is the one of the hardest and strongest commercial softwoods available in the market with an extremely high density of 41 lbs/ft3. High density makes it more difficult for decaying organisms to penetrate the wood. In its durability larch is equivalent to the oak. Other than Ipe, Siberian Larch is denser than all the other most commonly used decking materials, such as Southern Yellow Pine, Redwood or Cedar. Therefore, Siberian Larch can be classified as one of the most valuable building materials.
Longevity. In a scientific study on the properties of Siberian Larch, it was concluded that larch trees are composed of 75-90% heartwood in their natural existence. Heartwood is denser, less permeable, and more durable than the surrounding sapwood. Very few species possess such a large percentage of heartwood. European Standard EN 350-2016 classifies Siberian Larch among the most durable species and the most resistant to biological attack (rot, fungal attack, destruction of insects), ranking on this indicator first place, since the presence of natural fungicide arabinogalactan protects the wood from damage, while pine has only moderate decay resistance. Thus, larch will serve 4—5 times longer than other species without impregnation by special antiseptics. Use of non-treated larch wood in the construction reduces the risk that a person could get poisoned with chemical (antiseptic, impregnants) vapors.
