Timber Species:
Siberian Larch B
Siberian Larch is the premier softwood when it comes to cladding. Its natural attributes make it ideal for external applications as its durable, stable and dense which provide excellent weatherproof performance.
Siberian Larch is slow grown and a light straw colour with a dynamic grain pattern and is available in two grades, Unsorted and Sawfalling.
We describe our stock as A grade and B grade for ease. A Grade allows for occasional small knots (up to 5p size) but many of the boards can be clear of defect. B Grade allows for frequent knots and some larger knots up to the size of a 50p.

Our Siberian Larch B Cladding Products

18 x 94mm (86mm Cover)
V Grooved Cladding DTC2
18 x 94mm (86mm 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 94mm (78mm Cover)
V Grooved Secret Nail Cladding DTC6
18 x 94mm (78mm Cover)
V-Grooved Secret Nail Cladding works in the same way as a standard V-Groove creating a neat ‘V’ 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 Sleek and contemporary profile free of any visible fixings.

18 x 92mm (86mm Cover)
Vertical Shadow Gap Cladding DTC12
18 x 92mm (86mm Cover)
Our DTC12 profile — Vertical Shadow Gap with 86mm cover — is increasingly popular for those architecturally-lead projects.
Each board is machined to contain a 10mm square gap. Once installed, sunlight and outdoor lighting produce a subtle shadow effect across the cladding.
The result is a contemporary, clean and visually striking profile, ideally at home in any designer outdoor space.

18 x 94mm (78mm cover)
Vertical Shadow Gap Secret Nail Cladding DTC14
18 x 94mm (78mm cover)
Our DTC14 profile — Vertical Shadow Gap Secret Nail — is machined to have a square 10mm gap between each piece once installed on your property. This results in a smart linear shadow appearance, which changes throughout the day as a result of sunlight and outdoor lighting.
Adding to this profile’s designer credentials is its extended top half at the rear, concealing your stainless steel nails. The result is a modern, striking and clean profile free of any visible fixings. The smaller board size of DTC14 results in 78mm of cover.
