Ways of wood modification
Various ways have been developed to preserve or improve the wood.
Chemical wood modification
Chemical process in which the structure (cell) changes as a result of a chemical reaction. By adding a substance, the water in the cell walls of the wood is replaced. As a result, the wood absorbs less moisture, becomes more stable, is more resistant to UV radiation, is harder and can easily be finished with paint systems. With the correct use of substances (for example acetylation), chemical modification is - contrary to the name - a safe and environmentally friendly process.
Thermal wood modification
Wood is heated in an oxygen-free environment. This can be done, for example, with steam, in vacuum, under water, with gas and with oil. For example, wood is dried in high-tech computer-controlled ovens at an average temperature of 230 degrees Celsius. Heat treatment reduces water absorption and increases water resistance. Reducing moisture increases mold resistance and therefore durability. This ensures that the cell structure changes without damaging the type of wood. In addition, stability also increases. It is completely sustainable and no chemicals are used in the process. This gives the wood a very durable property and makes it extremely stable.
