* Board widths are subject to change in response to changes in moisture levels. Decking is kiln-dried to approx 16-18% prior to machining, but may vary between production and installation on site. Decking is dispatched from our swawmill at given sizes, but a margin of error should be used when producing decking layout drawings for expansion and contraction in the timber.

Siberian Larch Decking Sinus Profile

Siberian larch is very resinous and extremely hard wearing, making it one of the toughest and most durable softwoods in the world. Siberian Larch Decking Sinus Profile makes excellent decking for both residential and commercial projects. This timber benefits from impressive dimensional stability, low cost of installation, low maintenance and high manufacturing standards. It has a natural resistance to decay! Siberian larch decking doesn’t need extra treatment and can be installed in its natural state.

This Sinus Profile is reversible due to it being Ribbed on both sides, the length has eased corners. Siberian Larch is valued for its tough, waterproof and durable qualities. Siberian Larch Decking 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 decking 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 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 Sinus Profile 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.
