Grade B Siberian larch VHL1
Siberian Larch (Larix siberica) (durable softwood)
As the name suggests, Siberian larch originates from the coldest and most inhospitable parts of northern Europe.
The wood is a golden yellow colour with a strong grain pattern. The trees are very slow-grown, resulting in tight growth rings. Unlike the British larch, the knots in the Siberian species are light grey in colour and tend to stay solid, even after drying and machining.
Siberian larch is very resinous and extremely hard, making it one of the toughest and most durable softwoods in the world. When used as cladding, Siberian larch is ideal for really exposed elevations or areas where there is likely to be physical damage, such as knocks or scrapes.
Siberian larch is available in two grades.
Grade A (Unsorted) - The majority of boards are clear of any defects with the remaining pieces containing occasional tight knots. Used where a clean contemporary appearance is required.
Grade B (sawfalling or fourths) – Contains regular, sound, tight knots. This is the grade most commonly used for cladding, and the grade used by Vastern Timber as standard.
BS EN350-2 Siberian larch is classed as durable and does not require treatment for external use, as long as the sap is excluded.
Workability: Siberian larch can be machined to a fine finish. Boards are prone to splitting, so fixings should be pre-drilled
