For exterior wood fencing and louver applications, our Gendai and Pika-Pika S4S profiles are heat-treated on both faces. They can also be machine-coated with your choice of exterior-grade oil finishes on both sides.
When using one of our S3S profile products in an installation where the back side would be exposed, the uncharred backs can be stained with any dark color to blend in with the burned faces.
For structural elements (e.g., fence rails, posts), standard framing lumber can be used to support visible cladding of sugi or yakisugi “shou sugi ban” plank products.

Sorting:
Our Gendai® yakisugi “shou sugi ban” products receive a single brushing to remove some of the delicate soot layer–leaving a smooth, consistent, and dark surface. Unoiled Gendai is suitable for exterior applications. This is a great option for owners who appreciate the natural beauty of wood and siding with a unique, ever-changing patina. Leaving the charred wood unoiled allows it to naturally weather in response to the local climate. The yakisugi heat treatment process hardens and protects the siding against pests, moisture, and fire. Available burned on both faces (S4S) for fencing or louver applications.

Sugi is often left unoiled in clean interior applications, or in exterior applications where a patina is desired. It can also be coated by the customer with standard tradecraft before or after installation. Leaving the wood unoiled in exterior applications allows it to weather naturally, according to the local climate.

Charred, unbrushed, and unoiled yakisugi “shou sugi ban” is as traditional as it gets. Unoiled Suyaki® provides a visual and cultural benchmark for our products. Used mostly for exterior applications, though it has also been used in Japan for interior ceilings as an air purifier. This is a great option for owners who appreciate the natural beauty of wood and siding with a unique, ever-changing patina. Leaving the charred wood unoiled allows it to naturally weather in response to the local climate. The yakisugi heat treatment process hardens and protects the siding against pests, moisture, and fire.

Yes. Our Gendai and Pika-Pika S4S profiles are heat-treated on both faces and can be machine-coated with oil on both faces. For S3S board installation where the back side is exposed, the back of the boards can be stained with any dark color to blend in with the burned faces.
For structural elements (e.g., fence rails, posts), standard framing lumber can be used to support visible cladding of sugi or yakisugi “shou sugi ban” plank products.
Yes—we do offer stock for batten and louver applications. Please see our product profiles for current availability.
Alternately, our plank products can also be ripped using a table saw into the desired width for various styles—such as board-and-batten or board-and-board. Touch up oil is provided with each lumber order and can be used to stain any ripped edges prior to installation.

Our wood products are frequently used in soffits or cosmetic roof decks. Pika-Pika and Joko clear grade Sugi (whether unoiled or with a transparent oil finish) are both commonly chosen for this purpose.
This gallery showcases work from an architect renowned for this aesthetic in Japan.
For fascia installations, we recommend either using our 5/4″ x 8″ S3S profile, or a structural subfascia under our 1×6” or 1×8” S3S profiles. Please plan on recoating the yakisugi surfaces with fresh oil every few years.
While occasionally seen in Scandinavian design, we do not recommend using wood plank products for roofing or other horizontal applications. Thin plank wood materials are prone to checking, twisting, and premature aging due to natural expansion and contraction.
Roofing applications require shorter-length shakes or shingles that allow for longitudinal expansion and contraction. If yakisugi is used on a roof or other horizontal application, plan on recoating yearly and eventually replacing the wood after several years.
