Timber Species:
Siberian Larch A
Beauty, durability and stability — Siberian Larch (Larix sibirica) is a premier softwood when it comes to exterior cladding.
Our extensive 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.

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.

Rainscreen Cladding DTC28
18 x 144mm (136mm cover)
Rainscreen cladding (also known as splayed or rhombus cladding) is made up of rhomboid-shaped boards equally spaced apart.
When installed, it provides a smart, design-led shadow slat appearance — a stunning exterior finish for any property.
As a purely decorative profile, the boards are not interconnected or interlocked. This means it should only be applied to a waterproofed surface.

Angle Bead or Corner Trim is a great way to finish off edges to your cladding project.
