Russwood’s SILA boards come in a warm mix of colours, from light reddish brown through to golden browns. When detailed correctly, the weathered timber changes to a beautifully consistent silver grey tone, which is highly desirable in many cladding projects.
With clearly marked annual growth rings, a straight grain and relatively few knots, the overall look is clean, contemporary and, above all, consistent.
For external cladding purposes, Siberian Larch is a naturally durable timber (Class 3 according to BS EN 350-2) due to the presence of tannins in the wood, creating a high resistance to decay and rot. Due to its high density, it’s also more difficult for harmful organisms to penetrate the wood.
The end result is that Siberian Larch is one of the toughest and most durable softwoods in the world, with an expected lifespan of 50-100 years when subject to general outdoor exposure.
As Russwood SILA contains very little sapwood when correctly fixed, it does not require maintenance and, if left untreated, will weather to a silver / grey.
Due to the infrequent knots and tight grain, optimal paint adhesion can be achieved, particularly on sawn surfaces. Consequently, SILA is an ideal timber for vacuum coating with your choice of colour from our extensive range, or with SiOO:X.
