Siberian Larch Cladding

Siberian larch is a hard and naturally durable softwood that offers a cheaper alternative to cedar. Siberian larch cladding is hardwearing but it is unstable and prone to movement.

Siberian Larch Cladding Features

Siberian larch trees grow very slowly and consequently the larch wood is extremely dense and strong when compared to other softwoods such as spruce and cedar. The high resin content found in Siberian larch makes it one of the most durable softwoods in the world.
Siberian larch, which is a straw colour, should not be confused with the European larch growing in Britain, which is pink in colour.
Siberian larch cladding is generally available in two grades, which in the trade, are confusingly named ‘Unsorted’ and ‘Fourths’ (or sometimes ‘Sawfalling’). For ease, we describe our stocks as either Grade A or Grade B. Grade A allows for occasional small knots, although many boards will be clear of defects. Grade B allows for frequent and larger knots.
For a comparison between British and Siberian larch watch our video.

Characteristics

Appearance
Siberian larch is a golden yellow colour with a strong grain pattern, similar to pine. Depending on the grade, the boards may include occasional, or many, sound knots.

Weathering
Siberian larch cladding weathers relatively slowly, often taking two years to reach a silver-grey patina. Larch is quite consistent and is not reactive, and as such, will weather relatively evenly. Northerly elevations may weather to a darker grey than those facing South. In damp areas or near trees Siberian larch does sometimes grow a fine black mould on the surface.

Desired service life
Occasionally wet 30 yrs. Frequently wet 15 yrs.

Movement class
Large

Resistance to impact
High

Working properties
Good workability. Takes fixings satisfactorily although can be prone to splitting.

Density
570 – 650 Kg / Cm3

Extractives
Siberian larch contains resin rather than oil or tannin. The resin is fixed by kilning and does not tend to bleed. The resin is not reactive.

Installation

How to fix
Pre-drill and hand nail with stainless steel nails through the face. Do not attempt to secret nail through the tongue. We do not recommend first fix nail guns because the nails are unsightly but the method does work.

** Be sure to leave an expansion gap between boards**
