Timber Species:
Siberian Larch A
Beauty, durability and stability — Siberian Larch is a premier softwood for exterior cladding.
Our range covers many different horizontal and vertical profiles across V-groove, shiplap, shadow gap, rainscreen and feather edge.
A pale yellow-golden brown timber with a characterful grain pattern, Siberian Larch is available in two grades — A (unsorted) and B (sawfalling).
Siberian Larch A consists of 1st, 2nd and 3rd grade boards, with no nominated percentage of each included, but consistently tested to meet the recognised unsorted grade.
1st grade boards are virtually clear with sound pin knots; 2nd grade can contain 5–6 sound or dead knots up to the size of a 5 pence piece; 3rd grade boards can contain up to 10–12 mixed size knots up to 10p size, some of which can be dead or loose.
Our Siberian Larch A Cladding Products
18 x 144mm (136mm Cover)
V Grooved Cladding DTC3
18 x 144mm (136mm Cover)
V-Grooved Cladding is the most popular choice of profile, both on small and large scale projects. When the easy fit tongue and grooves butt together they make a neat ‘V’ shape that creates a faint yet effective shadow line. A clean, uniform and contemporary profile.
18 x 144mm (128mm cover)
Vertical Shadow Gap Secret Nail Cladding DTC15
18 x 144mm (128mm cover)
Our DTC15 profile — Vertical Shadow Gap Secret Nail — creates a pronounced 10mm square gap when installed. Lighting visually enhances the finished structure, producing smart, subtle shadow lines.
This profile is modified to have an extended top half to the rear of the piece, allowing for stainless steel nails to be concealed after installation. A modern, striking and clean profile free of any visible fixings, the larger board size of DTC15 results in 128mm of cover.
18 x 144mm (128mm Cover)
False Double Vertical Shadow Gap Secret Nail Cladding DTC47
18 x 144mm (128mm Cover)
A unique profile with twice the impact and half the fuss! This profile provides a dynamic, false central shadow gap on a single board. Narrower, sharper profile definition with half the fitting time, a spin on this popular trending choice of cladding. Vertical Shadow Gap Secret Nail Cladding works in the same way as standard creating a pronounced 10mm square shadow gap which uses natural sunlight to visually enhance the building but is modified to have an extended top half to the rear of the piece allowing for a nail to be covered over after fixing. A modern and striking profile free of any visible fixings.
18 x 144mm (128mm Cover)
Horizontal Shadow Gap Secret Nail Cladding DTC19
18 x 144mm (128mm Cover)
Horizontal Shadow Gap Cladding works in the same way as the standard profile creating a softer 10mm wide V shape shadow line but is modified to have an extended top half to the rear of the piece allowing for a nail to be covered over after fixing. A modern and striking profile free of any visible fixings.

Featheredge Rebated Cladding DTC25
18 x 144mm (128mm Cover)
Featheredge Rebated Cladding is a variation of a standard Featheredge but has a rebate in the rear of the board for easy of fixing. The most traditional profile very much associated with agricultural buildings, this is still a very popular choice for barn conversions and out building renovations as it retains their rural roots yet provides clean lines and great weather proofing. A smart and timeless profile.
