Russwood’s VG SILA boards come in a warm mix of colours, from light reddish brown through to golden browns. The grain of the wood is exceptionally straight and the annual rings are close together. Growth rings mainly run in straight lines on the surface which means minimum risk of surface checking and minimum risk of splinters forming as a result of delamination between the growth rings. When exposed to the elements and sunlight, the colour of the deck will change to an even shade of grey. If used in a project alongside SILA cladding, the weathering of both products will ensure consistency of the overall look over time.
VG SILA is supplied as a mix of the highest Siberian larch grades with approximately 70% being virtually clear grade (knot free), resulting in a clean, contemporary timber decking option.
VG SILA is comprised of vertical and semi-vertical grain boards. Cut from the heartwood with growth rings ranging from 30 - 90°, VG SILA is more stable than flat sawn boards.
The way a decking board is fixed and detailed can have a major effect on its lifespan. We have teamed up with Austrian fixings specialists, Sihga, to provide a system that makes decking look better and last longer. We can write these systems into the NBS Q55 specification. The VG Sila decking can be secret fixed with DielenFix® or face fixed with L-Go Fix stainless steel screws and Kompefix. DielenFix® provides an ultra clean look with face free of fixings and enhanced durability due to all four side ventilation.
GripDeck® is a highly effective slip-resistant insert which is applied in-house to our SILA decking. The specially bonded aggregate inserts provide an attractive and long-lasting solution to slippery decking, being rated as “extremely low potential for slip” (BS7976:2002 Part-1 3 using the Stanley Pendulum Test). GripDeck® is particularly desirable for bridges, stairs, ramps, forest walkways and commercial environments such as cafes, pub gardens, shopping centres and parks.
GripDeck® can be applied with two strips per decking board and will provide excellent slip resistance in both wet and dry conditions.
One of the primary benefits of SILA as a decking material is that it is one of the toughest and most durable softwoods. Unlike most commonly available decking timbers, it is naturally durable, being rated as Class 3 according to BS EN 350-2.
This means that it does not require any chemical treatment and, in comparison to pressure treated decking, has enviable environmental credentials.
This natural durability is the result of resin and extracts in the wood, combined with a high density, which reduces the wood's vulnerability to rot, decay and insect damage. This is of key importance when considering a decking material, since a hard-wearing timber is required in order to ensure the long-term safety of the deck, regardless of its environment and level of footfall.

Russwood's VG SILA is more dimensionally stable than standard flat sawn offerings. Flat sawn boards can move up to 50% more than vertical grain boards. This reduced propensity to move means minimal shrinkage and expansion.
SILA is a dense timber, classified by BS EN 350-2 as approximately 628 Kg/m3 at a moisture content of 18%. As such, it is not easily damaged and therefore is ideal for high traffic areas such as bridges, hotels, retail outlets and other commercial properties.
Due to the natural durability and beauty of SILA decking, it is generally left untreated to weather to a consistent shade of silver / grey. SILA is suitable for coating in SiOO:X, a breakthrough silicone technology, to provide a genuine silver lustre. SiOO:X creates a weathered appearance at an accelerated rate. Following application, all areas, regardless of protection and exposure, take on a consistent tone which provides a solution to differential weathering.

Russwood’s SILA is FSC®-certified, meaning that it is sourced from well-managed forests.
The standard Vertical Grain / Semi Vertical Grain SILA decking profile is a 27 x 92mm square dressed with bevelled edges.
VG SILA decking is supplied in running meters in various lengths up to 5.1m. Please note that decking is supplied as a linear meterage based on random stock lengths at time of picking order. Other sizes may be available on request.
SILA is one of our mid-range decking products, with prices starting at £40.71m2 for the standard profile.
