Maintenance Free Timber Cladding 

This is the most practical feature of charred timber cladding, maintenance is not required. 

The improved characteristics of charred timber allow this product to resist UV and the environment never requiring maintenance. The charring of timber case-hardens the cells giving improved UV and weather resistance.

In Japan charred timber cladding traditionally was never oiled, and lasted 80 - 120 years. Current best practise is to oil stain once at the start of its life.

The charred timber is stronger than natural timber and most home owners agree Yakisugi improves over time due to the natural ageing process.  Some home-owners choose to stain once every 7-10 years to keep that fresh new colour look, but this is not necessary.

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.

Environmentally Correct.

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.
