About the product

Yakisugi, also called shou sugi ban, is a Japanese technique that burns
the surface of the wood in a controlled way to create a protective layer
naturally. This improves durability and resistance to moisture, UV rays, insects
and fungi, while creating a distinctive finish.

We follow the traditional method:
1. Charring: controlled burning that forms the protective layer.
2. Brushing: cleaning or smoothing depending on the finish.
3. Oiling with natural oils: fixes the colour and improves durability

Pine/spruce, larch, Thermo-D and Accoya in brushed or unbrushed finishes.
We also offer an exclusive collection of premium woods; please ask about
availability.

It depends on the climate and application:
● Thermo-D Yakisugi: highly stable in climates with sharp changes in
temperature.
● Larch Yakisugi: highly moisture-resistant and historically used in
shipbuilding.
● abeto yakisugi: gran relación peso-resistencia en climas secos o
temperate climates.
● Accoya Yakisugi: maximum durability.

With minimal maintenance (removing dust and re-oiling with natural oils if you
desea mantener el color), el yakisugi ofrece 50–100 años de vida útil. El color
naturally evolves towards grey or brown tones depending on orientation and exposure.

Yes. It is safe, non-toxic and free from smoke odour after oiling with natural
naturales. Es perfecta para paredes, techos y elementos decorativos

Our finishes achieve D-s2,d0 under European standards. The final classification
depends on the finish, the complete facade system and the project.

● Thickness: 20 mm (facades) and 28 mm (terraces).
● Widths: 95, 120 and 145 mm.
● Lengths:
○ Larch: 3, 4, 5 and 6 m (fixed lengths).
○ Pine/spruce and Thermo-D: 3–6 m in 30 cm increments.
○ Accoya: subject to availability.

Applications

On facades, terraces, fences, interior cladding and custom projects.

Yes, especially with brushed finishes. Oiling with natural oils helps
preserve texture and colour. Near a swimming pool, ask for the recommended
brushing specification.

Yes. It is an excellent solution for exterior fences: larch and thermally modified wood
offer the best resistance to moisture and decay.
Abeto funciona muy bien en climas secos o templados.
For marine areas or premium projects, Accoya provides maximum durability (subject to availability).

Installation and maintenance

Like any solid exterior cladding: on a ventilated facade, with fixings
that remain visible and accessible. Installation can be horizontal, vertical or diagonal.

Tornillos o clavos inoxidables a2 o a4. rastreles a 40–60 cm (ejes) y 2 fijaciones por
support.

El aceite natural fija el hollín en carbonizados profundos, estabiliza el color y
extends UV protection.

Yes, provided it is installed on a ventilated facade and follows the
recommendations of the selected fixing system. Thermally modified wood (Thermo-D) is particularly suitable for this method.

● South-facing facades: 5–10 years
● Fences: 3–8 years
● Terraces: 1–3 years
si se acepta el envejecimiento natural (torna a grises/marrones), el reaceitado es
optional.

After installation and cleaning with water, natural-oil treatment prevents
significant residue in normal use.

Yes, we can apply a fire-retardant treatment for projects that
require it, in accordance with current regulations. With this treatment, the wood
may achieve B-s1,d0 under European standards. The final classification
will depend on the complete facade system and the materials used.
