SiOO:X Impregnation has an extensive range of application. It is used across all wood types – softwoods, hardwoods and engineered woods. It has and is being specified by architects, end users, developers, constructors, contractors and consumers. SiOO:X is used in the public space and on commercial and private projects.

Typical applications are decking and terracing, cladding, jetties and bridges, artwork and landscape furniture.

Because of its environmental strengths and aesthetically pleasing natural appearance SiOO:X has been chosen by world leading architects particularly in highly sensitive and protected environments. In the most demanding and testing locations such as coastal locations SiOO:X has a proven record. 

Appearance and weathering

All too often the appearance of new timber clad buildings is ruined by uneven weathering (see Wood weathering). It is quite common to see buildings where the shaded areas are still unweathered whereas the exposed areas have already changed to the silvery-grey colour associated with exposed wood. Aesthetics is hugely important in the built environment and this patchy weathering puts people off from specifying timber as a cladding material. 

The SiOO:X products prevent uneven weathering and react with the wood to produce a pleasing even grey natural looking surface within a few months of application. This accelerated weathering takes place through a chemical reaction of the SiOO:X system within the top few millimetres of the wood surface and so it is a permanent change - see Sioo Wood Protection - a new wood modification for the UK
