With a lifespan of 50 -100 years when correctly detailed and subject to general outdoor exposure, Siberian Larch is similar to Western Red Cedar. Better durability properties can only be achieved with Accoya wood. Siberian Larch is graded to C24, it is a moderatly durable timber with low shock resistance.

Siberian Larch is valued for its tough, waterproof and durable qualities. Siberian Larch Timber is a good choice for a wide range of projects from large-scale construction to small self-builds. It is popular with architects and construction companies alike due to its aesthetic beauty, durability and longevity. Siberian Larch timber has been used for residential and commercial applications—including schools, shops and sports facilities. The timber is resistant to rot when in contact with the ground, and is therefore suitable for use as posts and in fencing.

The remarkable qualities and unique performance characteristics of Siberian Larch have led it to being referred to as “the tree of eternity”.

Compared to spruce and pine, Siberian larch timber is more weather-proof because of its denser wood structure (about 40% higher density than spruce/pine) and its high content of resin. Because of this, Siberian larch sawn timber doesn’t need extra treatment and can be installed in its natural state even in outdoor conditions. Over time, natural Siberian Larch will obtain a grey shade in outdoor conditions without losing its durability. However, if the natural colour of the timber is to be maintained this can be achieved by using a UV protection oil.
