Siberian Larch Decking – SLA Profile

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 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 Decking doesn’t need extra treatment and can be installed in its natural state even in external conditions. Over time natural Siberian larch decking 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 Decking 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.
