Siberian Larch Sawn Timber

Siberian Larch Sawn Timber

With a lifespan of 50 -100 years when correctly detailed and subject to general outdoor exposure, siberian larch sawn timber is similar to Western Red Cedar. Better durability properties can only be achieved with Accoya wood.

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 specified 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 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 more dense wood structure (about 40% higher density than spruce/pine) and 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 external conditions. Over time natural Siberian larch will obtain a grey shade in external conditions without losing its durability. However, if the natural colour of the timber is to be maintained this can be achieved on site by using a UV protection deck oil.

Siberian Larch sawn timber has a high percentage of heartwood and a minimum of sapwood. Dry timber is approx. 628kg / m³ with a moisture content of 18 – 16%. This higher density timber means it is not easily damaged and therefore is ideal for heavier traffic areas or applications where there is the chance of physical damage such as knocks or scrapes i.e. schools, shops, shopping centres. etc.
