Sumii Dune
Charred + Brushed + Coated
Traditional charred Yakisugi (Shou Sugi Ban) Japanese cedar, double-brushed and coated for a neutral sand‑beige finish with soft grey undertones
Product Overview
Sumii Dune pairs authentic double-brushed Yakisugi texture with a breathable protective coat that produces a calm, sand-beige tone softened by subtle grey undertones. The aggressive brushing reveals strong grain and fibre relief, while the coating stabilises colour and improves cleanability, making Sumii Dune ideal for modern, minimalist cladding where a neutral, durable backdrop is required. It is one of several finishes available within the Sumii Yakisugi range.

Specifications
Our boards are supplied in two profiles, tongue and groove or shiplap.
Species, thickness and length are the same across both; only the cover width differs:
- Species: Cryptomeria japonica (Japanese cedar / sugi), density 350 to 420 kg/m3
- Board width: 140mm total. Cover width 122mm for tongue and groove, 129mm for shiplap. Use the cover width for take-off, not the 140mm face.
- Thickness: 21mm
- Length: 3,930mm
- Serviceable life: 30+ years
- Moisture content: 14% or lower at installation
The low density that makes sugi easy to handle and quick to install is the same property that gives genuine shou sugi ban its character. It is a cladding board, designed and milled for the wall.
Installation Tips
Always include a ventilated back cavity (min 20 mm), stainless steel fixings (use 316/A4 in coastal zones) and leave a 6–10 mm expansion gap to accommodate seasonal movement. Pre-finish cut edges with the supplied breathable hydrophobic coating and avoid non-breathable sealers; expect recoats roughly every 2–3 years in coastal exposure and 3–5 years inland.

FAQ
Sumii is a Yakisugi a.k.a Shousugiban charred timber cladding made from premium Japanese cedar (sugi), featuring a distinctive hard-brushed finish that brings bold texture and depth to the wood’s surface. Each board is handpicked for colour and grain consistency, offering a striking and tactile aesthetic for both interior and exterior applications.
Unlike smoother profiles such as Hakuu or lightly brushed finishes like Benii, Sumii’s hard-brushed surface creates a more pronounced texture, enhancing the visual impact and tactile quality of the timber. This makes it ideal for projects that prioritise strong, architectural statements while still benefiting from Yakisugi’s durable charred surface.
Sumii is perfect for exterior cladding, architectural facades, feature walls, and high-end interior applications. It is suitable for both vertical and horizontal installation and complements contemporary, rustic, and traditional design styles that require a textured finish.
Coated boards feature a breathable, non-film-forming finish with hydrophobic protection, resisting UV, moisture, and dirt build-up. When installed without oil, Sumii will develop a natural patina over time; re-oiling can be done later to maintain or enhance the colour. Regular gentle cleaning is recommended to preserve its bold texture and refined appearance.
