Shou Sugi Ban: Charred Timber Cladding

Shou Sugi Ban charred timber cladding brings an elegant, timeless aesthetic to any project. Also known as Yakisugi or Japanese burnt timber cladding, Shou Sugi Ban is a traditional Japanese method of charring timber with fire. The process results in a black carbon layer on the timber boards which protects the material and reduces its maintenance requirements. Shou Sugi Ban is machined to the same profile as our Trendplank T&G Timber Cladding and will fit all Trendplank Corner Trims and End Stops.

Profile & Sizes

  • 120mm x 19mm
  • 70mm x 19mm


Our Shou Sugi Ban burnt timber cladding can be installed as vertical or horizontal wall cladding in timber frame construction or masonry construction. Cladding will require pre-drilling and screw fixing through the tongue. The next board groove should cover the screw in the previous board. Shou Sugi Ban is end-matched, end matching is applied to the ends of the boards so that they can be joined off the stud. End matching is a tongue and groove profile that improves waterproofing and eliminates the need to measure and trim the ends of the boards. This will enable you to save time and minimise waste during installation.

What is Charred Timber Cladding?

Charred Timber(also known as Yaki Sugi and Shou Sugi Ban) is a centuries-old Japanese method of wood preservation. The literal translation is ‘burnt timber board’, the product is used for cladding, screening, and timber ceilings.

Charred timber cladding is highly valued for not only its stunning looks but also its ability to repel rot & insects and it’s fire resistance due to the layer of carbon created through the burning process. Charring the timber also strengthens the timber resulting in a more durable cladding.

What is charred Timber and what does charring wood do?

Charring Timber means you have a protective carbon layer of charcoal on the surface timber. This protective burnt wood layer increases the lifespan of the timber. Charred timbers can last up to 5-10 years without maintenance however it is recommended re-coating the timber more often to keep it hydrated and water resistant.

Can Charred Timber used internally?

As the Shou Sugi Ban is exposed weather the loose particles that causes this issue will wash off the timber from the wind and rain over a few months and the rubbing off will stop.

What is the R value for charred timber cladding?

The R-value for 19mm hardwood timber cladding is R 0.12.

ATFA states that all timber products have a material R-value. The thermal conductivity of kiln-dried hardwood (across the grain) is 0.16 W/mK. The R-value of a material is determined by dividing the thermal conductivity of the material (in metres) by the thickness so the R-value of 19mm thick kiln-dried hardwood is R 0.12. R = Thickness (m) / Conductivity (W/mK) =0.019 / 0.16 = 0.12 (m²·K/W).

Charring timber does not change the R-value.
