We supply various treated timber sizes suitable for a variety of building projects; this type of timber is available in a wide variety of thicknesses, with a range of widths and lengths to choose from. Our treated timber ranges from pressure treated timber all the way to sawn timber, all ready for use in your next construction job. Our treated timber prices are calculated per linear metre so you can be sure to get the best price for the amount you purchase. We also supply C16 and C24 joists for treated and sawn timber, for additional sturdiness and weight support. Check out the above products for a wide range of treated timber, suitable for many building projects.
What is treated timber?
Treated sawn timber is timber that has had chemicals forced into the wood, usually using a vacuum cylinder. The wood treatment takes place in a pressurised environment, so the chemicals can penetrate deeply into the fibres of the wood and provide extra strength throughout.
This is done by placing the wood into a special vacuum cylinder which is then drained of oxygen, drying out the wood. Then, a chemical preservative is flooded through the cylinder at high pressure, forcing it deep into the fibres of the wood. The chemicals used may vary depending on the size of the wood, but the finished product is usually one of two colours: green or brown.
Both types of treated timber offer the exact same durability and performance, with the only variation being aesthetic. To learn more check out our treated timber guide.
What are the main benefits of using treated timber?
The main benefit of treated timber is the increased durability the wood receives as a result of treatment. You can think of timber treatment as a kind of toughening process, similar to how certain types of concrete are also treated to achieve maximum strength, impact resistance and scratch resistance. This is useful because it makes treated timber ideal for large-scale building projects or even garden decking.
Strength and durability aside, the following are some wonderful benefits of choosing treated wood for your building project:
- Treated timber helps prevent rot: A rotten piece of wood could be disastrous in a structure. As a result, treated timber can help mitigate these risks and to create an extremely sturdy construction that stands the test of time.
- Treated timber helps prevent decay: Insect attacks such as woodworm can thrive in the warm and dry conditions of a wood frame in a roof, wall and any other areas where wood is present. However, the wood preserving effects of the treatment process can help prevent decay, even in the case that insects become an issue.
- Treated timber lasts longer: High-quality treated timber lasts longer than wood that has not been treated, such as rough sawn timber. You will get a long term performance with treated timber, with a low chance of any replacements or repairs being necessary.
For example, to prevent deterioration of the wood in damp buildings or when using wood outdoors, our treated carcassing timber has received a pressurised treatment with a minimum-hazard preservative, such as TANALITH E. This helps to inhibit rot with no negative effects from the chemical.

Is treated timber environmentally friendly?
Due to treated timber being involved in a chemical process, you might be concerned about the potential environmental or health impacts it could pose. However, treated timber is perfectly safe when used in building structures as it will often be covered up.
Additionally, all treated timber planks that we offer have been responsibly sourced, meaning they carry an eco-friendly footprint with them. Both the chemical processes and the sourcing of the timber itself are done with sustainability in mind.
What is the best treated timber?
For pressure treated timber, we recommend CLS timber, which is kiln-dried for impressive levels of strength. When used for outdoor applications, CLS treated timber can help protect against rotting, moisture and environmental damage that can soften the wood exterior.
For structural projects, it is a good idea to use special structural timber products for the best results. For a very clean and neat finish, you can use our planed square edge timber (PSE), which will give you durability with a very aesthetically pleasing appearance, ideal for all kinds of indoor or outdoor work.
