Featured applications

Timber cladding is being used increasingly as a priority choice amongst architects and designers for use as a protective skin for buildings. This is a reflection of the natural and unique quality that wood provides. Whether the project is a large scale development or a small private dwelling, timber cladding gives greater flexibility in design, is versatile, attractive and environmentally friendly. Having made a significant investment in timber cladding the question of how it is best protected arises. SiOO:X gives long life, all round even protection and a light surface which ages beautifully. Featured in exterior cladding and engineered timber structures.

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.
