Our Technology

Made by Earth

The natural evolutionary process has shaped and created our environment, it is unique solutions and structures providing us with an endless source of inspiration and learning. Sioo:x patented wood protection is the result of our having observed, imitated and added to nature’s intelligent protection techniques.


Sioo:x essentially consists of a unique combination of silicon and potassium – two natural substances found all around us and which together create a natural shield similar to nature’s own wood protection.


Sioo:x Wood Protection is inspired by how nature protects itself using silicon. Trees and plants absorb silicic acid from the soil, which dissolves in water and is then transported in trunks and stalks, precipitating out in the organisms and making them stronger.


This is the process that gives vitality to both aspens in Nordic forests and teak trees in the rainforest. And it’s the same silicon that makes straw and reeds strong and rigid. Silicon also preserves the wood. You can see this in trees with petrified wood, which can be found in many places around the world. The cellulose in these trees have been replaced by silicon, which has protected them against all types of weather for millions of years.

Provides effective multi-protection

The silicon shield provides effective multi-protection against the forces of nature, regardless of climate.


Sioo:x is a proven water based silicate treatment which, if correctly applied and cared for, provides long life and a beautiful natural finish. It can be applied to most timber surfaces.


Sioo:x works with the wood to protect against:

  • 01 Sunshine and UV rays
  • 02 Rain, frost and snow
  • 03 Rot
  • 04 Algae and mould
  • 05 Termites other unwanted insects

A natural symbiosis

Patented technology

The patented silicon technology in Sioo:x protects and works with the wood in a process created by two products – wood protection followed by surface protection. The initial treatment with Sioo:x Wood Protection opens up the wood and penetrates deeply into the structure of the material, unlike old silicate-based products which remain on the surface of the wood and easily crack and flake off.


After this, Sioo:x Surface Protection is applied. This protects the wood protection, but still allows the right amount of moisture to enter, ensuring optimum conditions for the continued process of hardening and mineralisation. The silicon molecules then grow and expand in the cells and around the wood fibres, deep into the wood, creating a network. The network fuses the silicon to the wood, strengthening it and offering a unique silicon shield that protects and gives the surface a natural grey tint. Sioo:x wood and surface protection simulate nature’s own protective process and last for up to 15 years.
