Naturally durable Siberian Larch cladding

SILVALarch™ Tongue & Groove V-Joint Profile

Sure to stand the test of time while looking great on any contemporary façade, SILVALarch™ V-Joint cladding profile is durable, stable and dense, while being incredibly easy to install without visible nails thanks to the tongue and groove joint.

The bevel, where two boards meet, creates a neat v-shaped shadow line effect along the joint, making it the perfect timber cladding choice for a contemporary look, whether installing horizontally or vertically on residential or commercial buildings.

Quality Raw Materials from Certified Forests

The long, cold winters and short summers of the Irkutsk region of Russia produces slow growing Siberian Larch with dense, tight grain and few tight knots. With a plentiful supply of old growth logs from this vast forest area, our supplying sawmill can provide us with a quality that far exceeds the official 'GOST 26002-83' grading standards.

It is important to note that Siberian Larch (Larix sibirica) is not to be confused with European Larch (Larix decidua, Larix europaea), which grows mainly in continental Europe and also here in the UK. Although related, Siberian Larch has different physical properties and is widely regarded to be a superior material. Notably it has a different appearance, it is more dimensionally stable, denser and more durable (due to its growing conditions) than its European cousin.

Kiln Dried to Optimise Dimensional Stability

SILVALarch™ boards are kiln dried to a moisture content of 16-18% (+/-2%), perfect for the immediate application of coatings and suitable for installing with minimal site acclimatisation. Read more about the importance of kiln drying.

SILVALarch™ is graded numerous times at source and then again at Silva Timber during the production process.


SILVA A is the highest grade (comparable sawn grade ‘Unsorted’) containing the largest amount of mostly clear timber.


Our most popular grade SILVA B (comparable sawn grade ‘Sawfalling’) allows slightly more knots and other natural characteristics than A.


SILVA C (comparable sawn grade ‘Fourths’) is an economical grade that includes more frequent knots and a greater number of larger knots.


This product is FSC certified.

FSC is a world-wide, independent, non-profit, non-governmental organisation representing environmental and social groups and the timber and forestry industry. It aims to generate certification of forestry activity that incorporates clear guidelines and standards covering social, environmental and economic aspects of forest management.

Established in 1993 as a response to concerns over global deforestation, FSC is widely regarded as one of the most important initiatives of the last decade to promote responsible forest management worldwide.

The FSC label provides a credible link between responsible production and consumption of forest products, enabling consumers and businesses to make purchasing decisions that benefit people and the environment as well as providing ongoing business value.

Chain of Custody (CoC)

The FSC Chain of Custody (CoC) certification system provides an audit trail from forest to final use. The rigour of the system is ensured by regular independent inspection at all stages in the supply chain.

FSC chain of custody (CoC) tracks FSC certified material through the production process - from the forest to the consumer, including all successive stages of processing, transformation, manufacturing and distribution.

Only FSC CoC certified operations are allowed to label products with the FSC trademarks. The FSC label thus provides the link between responsible production and consumption and thereby enables the consumer to make socially and environmentally responsible purchasing decisions.
