Yakisugi

What is Yakisugi?

Yakisugi is a traditional Japanese shiplap or square-milled plank wall cladding that has been heat treated on the outward face.  In Japan it is commonly used in combination with white stucco in various ratios for exterior wall surfaces, each region having a slightly different aesthetic.

 

Some regions clad the entire structure with siding, some only wainscoting under a stucco upper wall, and some regions clad up to the shadow line below the roof overhang.  It is installed vertically or horizontally, and is also often used as a cosmetic roof deck on exposed eaves.  Please see our historical gallery of pics below to see how it weathers.

The process
Wood charring involves a few relatively simple steps:

  • Wood is treated with fire, until even texture is achieved;
  • The planks are brushed away to remove small particles;
  • Wood is washed with water;
  • The planks are treated with natural oils to ensure longevity.

 

Even though this technique has been around for centuries, this timeless wood preservation method is perfectly adaptable for interior and exterior design solutions nowadays. The result of wood charring is especially practical and also aesthetically pleasing. What is more, wood treatment with fire not only adds a beautiful colour and texture to the planks, but also ensures preservation from environmental factors (fire, decay, insects). Yakisugi technique is usually applied when working with conifer wood (pine tree, fir tree, cedar, cypress, larch). Wood treated by fire is not only aesthetically beautiful, but also lasts for decades.
