The ultimate contemporary profile

SILVALarch™ Channel Profile

Hugely popular in contemporary architecture thanks to its combination of durability and style, SILVALarch™ channel cladding will add a sense of depth and texture wherever and however you use it.

Whether indoors or out, or installed horizontally or vertically, the tongue and groove joint makes for easy installation, and the bold shadow line of the channel profile adds an element of modernity to almost any façade.

Made From Only the Finest Siberian Larch

Produced from the highest quality Siberian Larch from the Irkutsk region of Russia, the slow growth of the trees in the region makes for a very tight grain, and relatively few, well-interspersed tight knots. SILVALarch™ is produced from consistently high-quality wood fibre that far exceeds the official industry '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 a Uniform Moisture Content

In kiln drying SILVALarch™ to a moisture content of 16-18% (+/-2%), the boards dry uniformly which not only makes them more dimensionally stable, but lets you immediately coat them and install with minimal acclimatisation on site. Find out about the benefits of kiln drying.

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.

Silva Timber Products meets the requirements for FSC Chain of Custody Standard FSC - STD - 40 - 004 (2004) within the BM TRADA Certification Limited Scheme for TRADA - Trak chain of custody certification.
