(Shou Sugi Ban)
CHARRED TIMBER CLADDING
YAKISUGI CHARRED TIMBER CLADDING
Yakisugi also known as Shou Sugi Ban was devised 500-600 years ago to make wood less susceptible to fire, to keep away insects and rot, and improve the timber's life span. Yakisugi is a traditional Japanese method involves charring the face of Cypress timber at 1260 degrees C. The charred timber cladding is long-lasting and hauntingly beautiful. With yakisugi the char protects the timber from rain, decay and UV, over time the char erodes away to reveal the stunning textural timber grain below.
Below are some of the benefits of using Yakisugi
*Maintenance Free Timber Cladding
This is the most practical feature of yakisugi charred timber cladding, *maintenance is not required.
The improved characteristics of yakisugi charred timber allow this product to resist UV and the environment never requiring maintenance. The yakisugi charring of timber case-hardens the cells giving improved UV and weather resistance.
In Japan yakisugi charred timber cladding was traditionally never oiled, and many examples can be seen that have lasted over 80 years. Todat yakisugi best practise is to oil stain once prior to installation and again within 6 weeks on installation. Then enjoy the evolution your charred timber cladding will show.
The yakisugi charred timber is stronger than natural timber cladding and most homeowners agree yakisugi improves its look over time due to the natural ageing process. Some home-owners choose to stain thier yakisugi once every 3-5 years to keep that fresh new colour look, but this is not necessary.
*Although Yakisugi charred finishes are maintenance free, and we stand by our finishes, the timber manufactures conditions of warranty may require a maintenance cycle. Where this is the case this requirement takes priority.
Stronger Stable Timber.
The Japanese developed charring timber cladding as a way of improving the strength and performance of timber homes.
The process of charring timber cladding case-hardens the outer cell layers through high heat conditioning. The timber becomes both stronger and more stable from being exposed to high temperatures, much like the process used by Abodo Wood.
Stability in timber is critically important when reducing cupping and shrinking caused by weather changes. With our charred timber cladding we choose naturally strong stable timbers and then improve their characteristics with fire.
Improved Natural Resistance
Charring timber cladding causes an important reaction making our timber more unattractive to bugs and fungi.
The cell structure of timber is 65 to 90% Hemi-cellulose which is a tasty sugar to bugs and fungi. The charring process causes this food source to be burnt off leaving strong, but not tasty, lignin behind.
No food source means the timber is of no interest to fungi or bugs. Additionally, the charred timber is now case-hardened making it more difficult for unwanted pests to penetrate.
The charred surface is also a natural hydrophobic protection against weathering, at the same time as being fire retardant.
What we make today our children will live amongst tomorrow, and good planets are hard to find.
The Blackwood Project believes in a clean healthy future, which is why we improve the stability, durability and life span of timber without the use of chemicals.
We select naturally durable timber species that require no chemicals to last and improve them with fire.
Additionally, our flash firing process has a small carbon footprint, when compared with the high energy consumption kilns needed for thermally modifying timber.
Timber on your home locks away carbon, carbon the trees removed from the atmosphere. Timber is deemed to have absorbed the equivalent of 1.7 tonnes of CO2 for every tonne of its weight.
Using Yakisugi timber that is chemical free, with a low carbon footprint means your kids and grandchildren can enjoy this timber for a lifetime.
Making Yakisugi a healthier, cleaner, non-toxic natural cladding, and the correct environmental choice.
You can sleep easy knowing you have contributed positively to the planet.
