Wood type: | Siberian larch (Larix sibirica) |
Treatment: | None |
Timber density: | In dry state approx. 628 kg m³ |
Lifespan: | Proven life expectancy of 50+ years |
Quality class: | A or B |
Humidity: | Dried up to approx 16-18% (+/- 2%) |
Purpose: | Outdoor use |
Panel dimensions: | H: 180cm x W: 90 or 180cm |
Batten dimensions: | 20 x 55mm |
Gap: | 14mm |
Larch origin: | Sustainable forests of Northern Russia (Siberia) |
Appearance: | The wood come in a warm mix of colours, from light yellow brown through to golden browns with a strong grain, similar to pine. Depending on the grading, the boards may contain a few dark knots. |
Weathering: | When the boards weather, the color changes to beautifully consistent silver gray, which is highly desirable in many projects. |
Insect attack: | Resistant |
Treatability class: | Resistant |
Impact resistance: | High |
Scratches and abrasion: | Resistant |
Fire treatment: | Possible by impregnation. Can be treated to achieve fire classification: Euroclass B-s1,d0 |
Extracts: | Siberian larch is more likely to contain resin than oil or tannin. The resin is fixed by firing and does not tend to bleed out. Larch is fairly consistent and non-reactive and, as such, becomes relatively evenly weatherproof. |
Siberian Larch wood is naturally durable (Class 3 according to BS EN 350-2) – and therefore ideal for outdoor purposes – due to a combination of factors:
- The chemical composition of the wood creates a high resistance to rot and decay, which makes Siberian Larch one of the hardest and most durable softwoods.
- High density – this means that it is more difficult for decaying organisms to penetrate the wood.
- Long lifespan – lifespan of approx. 50-100 years with correct detailing and general outdoor exposure. Better durability properties can only be achieved with Accoya wood.
The natural durability of Siberian Larch means that no treatment of the wood is required and any coatings applied are for aesthetic purposes only.
Due to the high percentage of heartwood (75-90%) and the minimal proportion of sapwood, Siberian Larch is an extremely dense timber, which is classified by BS EN 350-2 as approximately 630 kg / m3 with a moisture content of 18%. As such, it is not easily damaged, making it ideal for highly exposed elevations, or applications where there is a likelihood of damage such as bumps or scratches.
The extreme continental climate in Siberia (Russia) produces a high proportion of late wood, which provides enhanced dimensional stability and enables a smoother machine finish.
In addition, our Siberian Larch is kiln-dried to around 16-18% (+/- 2%), the optimal moisture content for outdoor use. This moisture level is retained until delivery on site, so your Siberian Larch wood can be installed immediately. The benefit of kiln drying Siberian Larch, as opposed to air drying it, is that the timber dries uniformly and therefore achieves optimum stability.
Improved dimensional stability performance can be achieved by using narrower widths, for example 45mm or 70mm.
Siberian larch panels quick tips
Measure your workng area. Make sure your panel will sit neat and tight between the wooden or concrete posts.
Siberian larch is very hard and dense wood. Use professional equipment for best results.
We recommend using only high quality stainless steel screws to avoid corrosion and stains on the wood.
