Benefits of Yakisugi
Yakisugi is used today to not only create a dramatic and highly chic elegant visual with an often-reptilian texture but also has some incredible scientifically proven benefits as well.
Durable and long lasting
The life expectancy of Yakisugi is estimated at more than 80-90 years when properly maintained. You can still see some old Japanese houses with over 120 years old Yakisugi structure.
The carbon layer produced by charring the wood is resistant to weathering and fading very much the same way that stains or sealants would. The sun’s rays do not fade. Resistant for all kind of climate which can be humid or dry with extreme temperature fluctuations between seasons. This charring technique provide a cost-effective way of weatherproofing homes.
By slightly charring the surface of the wood, you essentially get rid the wood of its softer outer layer. When the wood is being burned, the porous material within the wood’s inner layer starts to close its’ pores and becomes much more stable and durable. This first step of the process will also make the wood more stable and stronger overall. This carbonization process of the outer layer of the wood, creates a layer of carbon that prevents the wood from burning quickly, which is what makes the Yakisugi flame-retardant.
When the wood is being charred, the pores within the wood start to shrink and close. What this means, is that it becomes much more difficult for the board to soak up and take on water.
Burning the wood is another choice for preserving the wood from decay since carbon does not rot.
Termites and other wood-consuming insects hate the layer of carbon produced by charring. Indeed, this process gets rid of soft wood cellulose, turning it to char. As a result, Yakisugi resists bugs without pesticides or other potentially harmful chemicals.
Striking. Very eye catching. A fusion of the modern and the elemental. Highly chic and elegant, enigmatic with a touch of drama and a kind of matteness and fineness of grain in the charring that is unlike anything else in the building industry.
You can get a variety of beautiful colors out of it depending on how deep you burn and how deep you brush, to further alter or enhance colors - and it can be stained as well.
If the intended use is to have it outside and exposed to weather (siding, fences, etc.), it should be oiled about every 10-15 years, which is fairly standard for exterior wood treatment. It will retain its colour better and will remain water-resistant longer if it is well-maintained.
For interior purposes where it will mostly be seen and not touched, it will require virtually no maintenance.
