The Process of Tanalising Wood
So, what is tanalised wood and how do we create it? Tanalised wood, also known as pressure-treated wood, undergoes a distinctive process that enhances its durability and resistance to insects, decay, and various weather conditions. This treatment process is called ‘tanalising’.
The process begins with selecting the type of wood. Softwoods are usually chosen because they absorb the treatment chemicals better than hardwoods. However, any wood that will be in contact with moisture or soil, such as that used for outdoor furniture, decking, or fence posts, can benefit from tanalisation.
Once the wood is selected, it is then placed into a large cylindrical holding tank known as a pressure treatment vessel. The tank is sealed, and all the air inside it is vacuumed out. This step makes the wood’s cells expand and opens its pores to absorb the preservative more efficiently.
After the vacuum stage, a solution comprising waterborne preservatives is then introduced into the tank under high pressure. The solution primarily contains copper (acts as a fungicide) and biocides (to repel insects). The high pressure forces the solution deep into the pores of the wood. The amount of preservative absorbed by the wood depends on several factors including the type of wood, its moisture content, and how long it’s subjected to pressure.
Following this stage, another vacuum cycle is performed to remove any surplus preservative solution from the tank. The final stage is allowing the treated wood to dry naturally or in controlled kilns depending on its end use.
This entire process ensures that not only does the surface of the wood get treated but that preservatives penetrate deeply into it. It makes tanalised wood much more durable and resistant than untreated timber. As a result, it can last up to 30 years or more, depending on the conditions it’s exposed to.
In conclusion, the question ‘What is tanalised wood?’ can be answered simply: it is wood that has been enhanced through a special process to stand the test of time and weather, making it an excellent choice for outdoor use.
