A Brief Guide To Tanalised Timber

Whether you’re hunting for a shed, fencing or natural building materials, it’s likely that you’ll have come across the term ‘tanalised timber’. This type of wood is used all over the world and is favoured for its range of enhanced properties.

If you’ve heard the term thrown around, but are unsure exactly what it means, or whether it lives up to its reputation, we’re here to help.

Read on to discover all you need to know about tanalised timber.

What Does It Mean?

So, let’s start with the basics. Tanalised timber is a term used to describe wood that has been treated with a chemical preservative called Tanalith. This treatment process protects the wood from a number of common issues such as rot, decay, and insect attack. Owing to its range of practical benefits, Tanalised Timber is ideal for a wide range of outdoor and exposed applications.

Tanalith is a water-borne solution that is applied to the wood in a pressure treatment process. The chemical is forced deep into the pores of the wood, providing long-lasting protection against rot and decay. The process is environmentally friendly and safe for use in construction and furniture-making.

Benefits Of Tanalised Timber

Why do so many people use tanalised wood? Put simply, pressure-treated wood offers a huge range of practical benefits, making it perfect for construction work. Below, we’ll outline a few key features of tanalised timber.


One of the key benefits of tanalised timber is its durability. Unlike untreated wood, tanalised timber can withstand exposure to the elements and resist moisture, making it ideal for outdoor applications. This makes it an excellent choice for fencing, decking, garden furniture, and other outdoor structures that are exposed to the elements.

Insect Resistance

Another benefit of tanalised timber is its resistance to insect attack. Wood-boring insects such as termites and wood beetles can cause significant damage to untreated wood, leading to costly repairs. Tanalised timber is treated with a chemical that acts as a deterrent to these pests, making it an ideal choice for areas that are prone to insect attack.

Aesthetic Appeal

In addition to its practical benefits, tanalised timber is also an attractive material for use in construction and furniture-making. The natural beauty of wood is preserved with the treatment, and the wood retains its warm, natural appearance. This makes it a popular choice for use in outdoor furniture, garden structures, and decks.
