For centuries, mankind has witnessed the unique performance of structures built out of Siberian Larch. Their experiences led them to refer to Siberian Larch as “The Tree of Eternity”. Some homes and churches in Russia have been estimated to be in existence for over 800 years. Perhaps the most famous example of its longevity is its use in the construction of the ancient city of Venice. Due to proximity, Europeans have been able to take advantage of this material. Architects in Sweden, Norway, Finland, Austria, and Japan are specifying the use of larch in the construction of residential homes and commercial spaces such as schools, museums, stadiums, and bridges.
Benefits are an impressive dimensional stability, low cost of installation, low maintenance, high manufacturing standards, and an aesthetically beautiful timber. However, the most amazing feature of Siberian Larch is its natural resistance to decay. The following properties are responsible for its durability.
Siberian larch is a tree with exceptionally rare qualities. This wood is one of the most weather-resistant tree species, being at least two times more durable than spruce or pine. Over time, rot resistance of larch-wood is increasing- it gains strength and durability.
Siberian larch durability is determined by its growth conditions and special resin composition. In extreme weather conditions a slow-growing tree has a very dense structure, which makes the wood harder and more resistant to external shocks. Larch resin is evenly divided between wood fiber and works as a good antiseptic: protects wood against moisture, fungal diseases and insects – pests.
In a long term larch retains all the characteristics of high-quality wood even without chemical treatment. Larch planks used in external applications without any treatment may eventually change the color, but will not lose its properties. Deep yellow, reddish color can be maintained using natural protective oils on wood. Siberian larch is irreplaceable if the chemical treatment of wood structures is not allowed, but resistance to weathering is necessary, for example, building children playgrounds.
