SILVALarch™ Siberian Larch Decking

From £32.52 £27.10 per sqm

The wood of Siberian Larch is highly valued for its remarkable properties and performance characteristics. It is strong and durable, possessing unusually high levels of resin, which give the heartwood a natural resistance to decay.

With its lustrous golden-brown colour and striking grain patterns, SILVALarch decking has a highly attractive appearance. Its good looks and physical/mechanical properties make it much sought after for exterior applications such as decking.

SKU: SL DECKING

SILVALarch decking is produced from the highest quality slow-grown Siberian Larch from the Irkutsk region of Russia, an area that experiences long cold winters and short summers. Wood from this harsh climate is much sought after for its natural growth characteristics – exceptionally slow-growing and, therefore, dense with tight grain.

Product Details

Size: 27 x 140mm.

Grades: SILVALarch decking is available in two grades. Each is hand-selected from the highest quality slow-grown Siberian Larch to meet our own stringent in-house quality standards. 

Profile: Deck board with rounded edges.

Surface texture: Smooth.

Moisture content: Kiln-dried at source to 16–18% (+/-2%). 

Key Properties

Colour: The overall colour of Siberian Larch is a lustrous golden-brown. However, closer inspection will reveal a range of colours varying from the creamy white of the narrow sapwood to the straw-coloured or dark, reddish-brown of the heartwood. 

Durability: Decay resistance of ‘Class 3 Moderately Durable’.

Stability: Siberian Larch has low permeability, so it can cope with varying levels of humidity without absorbing much water. Thus, it will not shrink or swell excessively in service.

Density: Siberian Larch is an extremely dense and hard timber, therefore able to withstand knocks and scrapes. Weighs 570 to 650 kg/m3 when dried to 12% moisture content.

Kiln-dried: SILVALarch decking is kiln-dried, giving it many advantages. The process improves dimensional stability, permits the immediate application of a coating, and enables installation with minimal site acclimatisation.

Grading: SILVALarch decking is available in 2 grades. SILVA A grade offers a clean, relatively knot-free appearance and is ideal for design-led projects. SILVA B grade displays well-interspersed knots with some boards free or practically free of knots. 

Sourcing/certification: SILVALarch decking is sourced from sustainable forests in the Irkutsk region of Eastern Siberia, Russia, and comes with full FSC chain-of-custody certification. 

Optional Extras

Coatings: The application of a coating is necessary to protect the wood and optimise its appearance over time. The coating should be applied to all surfaces, including ends, before installation. Choose from our wide range of high-performance wood coating systems.

Factory coating service: SILVALarch decking can be supplied factory coated. Having the coating pre-applied on all sides enables it to be installed at any time of year, regardless of the weather or temperature. Please Contact Us for a quotation.
