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

The wood of Siberian Larch is highly valued for its remarkable properties and performance characteristics. It is strong and durable, possessing especially high levels of resin which give the heartwood a natural resistance to decay. As one of the toughest softwoods in the world, Siberian Larch is comparable to oak in density and strength.

With its lustrous golden-brown colour and striking grain patterns, Siberian Larch is a highly attractive wood species. Its good looks and physical / mechanical properties make it much sought after for exterior applications such as cladding, decks, fences and screens.

This impressive set of natural attributes, combined with excellent environmental credentials and moderate price point, has made Siberian Larch a much sought-after wood species.

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.

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.
