Everything begins and is centred around exposing the Siberian Larch to scorching flames of 1100 degrees Celsius. Those flames carbonise the surface, shrink and seal wood pores while also forcing carbohydrates to evaporate. These results have many different pros. A burnt Shou Sugi Ban Siberian Larch plank is fire resistant. Due to a small outer layer of charcoal (soot) covering the plank, it is much more retardant when compared to any kind of regular dry wood.
Pore sealing acts as waterproofing. Those same pores were primary absorbers of moisture in the first place. If they’re shrunk and enclosed, H2O has nowhere to go, and timber becomes much more waterproof. With that being said, even though the charred Yakisugi Siberian Larches are more or less waterproof, due to the natural processing, they remain breathable.
And finally, with the evaporation of carbohydrates, the threat of vermin and parasites also fades away. Most common pests like Termites, Slugs and other parasites are not attracted to processed Shou Sugi Ban timber.
Japanese artisans perfected and refined this technology to the best of their ability. However, Degmeda takes it to the 21st century. By using modern, state-of-the-art technology and fusing it with the savoir-faire of experienced personnel, we can turn any piece of unprocessed Siberian Larch timber into top-notch naturally charred Siberian Larch which should last for decades on out.
After fire treatment, the planks are then smoothed and brushed to remove all roughness that might still be present. The final step in the whole process is treating the Siberian Larch with either hybrid water-based or natural oil. Oil applications improve looks and act as ‘longevity insurance’ for the product.
