What is the difference between tanalised and dipped timber?

Here at Total Sheds, being a supplier of timber throughout the UK, one of the many questions that we get asked is the difference between tanalised and dipped timber.

In this article, we’ll explain the difference between the two as well as the benefits and drawbacks of each. So, let’s take a look.

What is tanalised timber?

Also known as “pressure treated timber” tanalised timber is timber that has undergone treatment known as vacuum pressure impregnation.

This method of treatment forces special preservatives into the grain of the timber to protect it from rot and outside elements.

The process is fairly complicated and involves placing untreated timber into a treatment tank which is then sealed and filled with chemicals.

The tank is then activated and the chemicals are then forced into the timber. Once complete, the tank is emptied and the timber is left to dry out.

If a piece of timber is tanalised, it means that it is highly resistant to fungus and infestations.

Tanalised timber tends to last longer than dip-treated timber, although the process is more costly, which means the timber is slightly more expensive.

What is dip treated timber?

Dip treated timber is a timber that is treated by immersion within a bath of chemicals. Once fully soaked, the timber is removed and left to dry.

As well as protection, the process adds a beautiful golden or dark brown colour. Like tanalised timber, the wood is also protected from fungal decay and insects.

It is worth bearing in mind, however, that dip treated timber will lose its colouring over time and its ability to battle the elements will also fade.

That said, however, dip treated timber is more cost-effective, which means that it is cheaper to buy than pressure treated timber.

Owners of dip treated timber can help by adding further applications of preservative in order to lengthen its lifespan.

Which type of timber is best for me?

The best type of timber for you will depend on your individual situation.

Of course, much of the time, a person will choose a type of timber that better suits their financial situation, as dip treated timber is the cheaper option.

That said, if an individual has a larger budget available, they might choose to invest in tanalised timber, which will last longer and could save them money in the long-run.

There are other factors that come into play too, however, such as environmental ones.

If, for instance, you plan to use the timber in a garden or area that is well covered, and does not encounter strong winds or extreme weather, you could find dip treated timber lasting you many years.

On the other hand, if you live in the countryside, or on a hill, you may require more robust timber that will be in a better position to face the elements.
