A new generation of wood from OrganoWood
Silicium HT has evolved from our unique ecolabelled silicon technology, where we further enhance the durability of wood using a gentle, energy-efficient heat treatment.
The combination of both silicon and heat provides the wood with even better protection than is seen in wood treated solely with either silicon or heat. This is new technology for a new era. A non-toxic alternative to the usual pressure impregnated timber.
We continue to be inspired by nature’s own method of fossilising wood, which makes it immensely durable. To manufacture Silicium HT we have combined a number of tried-and-tested technologies: silicon minerals, heat and a vacuum process.
We use silicon, which is one of the most common elements in the earth’s crust, and a method called organocatalysis to enhance the durability of the wood and create a mineralisation deep inside it. We use heat and a vacuum process to dry the wood and improve the ability of silicon to penetrate deeper into it. Heat has, to a certain extent, a positive effect on the durability of wood. It both removes nutrients from the wood, which makes it more difficult for rot and fungi to take hold and spread, and reduces cracking in the wood’s surface. Use of vacuum technology enables us to lower the boiling point of the process, which gives us the positive effects associated with heat treatment but without us having to expose the wood to detrimentally high temperatures. It also makes the process more energy efficient.
A perfect synergy. That over time produces a beautiful silver grey hue.
