Siberian Larch slatted screens are an impressive contemporary alternative to the traditional fence, providing privacy yet allowing air and light to pass through. Slatted screens are very easy to build. They are an effective way to hide an unsightly wall or view and will make a stunning backdrop for a planting area.

Four different widths of board are available. You can either build your screen using one width, or for a different effect use a variety of widths.

Recommended Nails: Flat Head Stainless Steel Annular Ring Nails. 21 x 44m battens - 40mm. All other board sizes - 50mm.

Recommended gap between boards: 21mm

At a glance

A well designed and carefully built screen can provide a wonderful focal point for an outdoor space

SILVALarch™ slatted screen boards are 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 therefore dense with tight grain, and relatively few well interspersed sound tight knots. With immediate access to a plentiful supply of old growth logs from this vast forest area, our supplier is able to provide us with Siberian Larch of an exceptional 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.

SILVALarch™ slatted screen boards are available exclusively through Silva. They are sustainably sourced from well managed forests and supplied with full FSC chain of custody certification.

Widths and Lengths

SILVAlarch™ slatted screen boards are usually available from stock in the following sizes:

Widths: 21 x 44, 21 x 96, 21 x 121 and 21 x 146mm

You can check current stock availability and select your chosen board width and length(s) from the drop-down menu above. Full pack quantities are also available.

Kiln Dried

SILVAlarch™ is kiln dried to a moisture content of 16-18% (+/-2%), the optimal moisture content for external cladding in the UK. Among its many benefits over air drying, the kiln drying process enables the boards to dry uniformly to achieve optimum dimensional stability. It also enables immediate application of coatings and minimises site acclimatisation. For more information on the benefits of kiln dried timber click here.

SILVAlarch™ is re-graded by Silva to meet our own more stringent in-house standards and to reduce site sorting and wastage. Choose from our two grades:


SILVA A is the highest grade (comparable sawn grade ‘Unsorted’).


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

Environmental Information

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.
