What is pressure-treated timber?
Pressure-treated timber, also known as preservative-treated timber, goes through a preservation process where chemical preservatives are infused into the wood fibres. This is undertaken to enhance the timber’s durability and resistance to various environmental factors, including decay, insects, and moisture. By selecting the right use class of treated timber, you can ensure the longevity of your fencing or decking project while maintaining resistance to decay and insect damage. Choosing the right type of pressure-treated timber is vital, as it can impact the performance and lifespan of your installations, helping them to last and overcome environmental challenges. Treated timber also promotes sustainability by prolonging the lifespan of wood products and reducing the need for frequent replacements, therefore minimising environmental impact.
What are the different levels of treated timber?
Pressure-treated timber is classified into several categories depending on the level of protection it provides against decay and insect damage. The most common classification system includes Use Class 3 and Use Class 4, each representing levels of treatment and suitable applications. These use classes are a key factor when choosing timber for outdoor projects, such as fencing or decking. They highlight the treatment necessary to protect the wood based on its exposure to environmental challenges like moisture and rot. Higher use class levels indicate a greater need for enhanced protection to ensure the timber remains durable in more challenging conditions.
Class 4 Timber Treatment
Class 4 timber treatment, also referred to as UC4, provides a high level of resistance against fungal decay and insect attacks. This treatment method involves infusing preservatives deep into the wood fibres under high pressure. By penetrating the wood effectively, UC4-treated timber offers long-lasting protection against rot, termites, and other wood-damaging organisms. UC4-treated timber is typically used in external applications that come into direct contact, or close proximity, with the ground or freshwater such as garden fencing, including fence posts and decking posts.
Other uses for UC4 timber include:
- Agricultural timbers
- Retaining walls
- Playground equipment
- Joists and sub-structures
Class 3 Timber Treatment
Class 3 timber treatment, known as UC3, offers a moderate level of protection against decay and insect damage. This treatment process involves applying preservatives using pressure and vacuum techniques. UC3 timber is available in two types: coated and uncoated, both suitable for external above-ground applications such as fence panels, rails and boards and decking boards. UC3 timber provides good resistance to normal weather conditions, direct ground contact should be avoided.
Other uses for UC3 timber include:
- Cladding (including battens) and fascias
- Gates
- Agricultural timbers (not in-ground or manure contact)
- Roof soffits and fascias
- Bargeboards
- Valley gutter timbers
- Specialist external joinery (such as window frames and doors)
- External load-bearing timbers

The Benefits of Pressure-Treated Wood for Fencing & Decking
Whether you’re a homeowner or professional embarking on a fencing or decking project, ensuring that you use the right type of timber is essential to the project’s success. Here are some of the many benefits of using pressure-treated timber for your fencing or decking project…
- Improved Durability
Pressure-treated timber is built to last, which is hugely beneficial for installations like fencing and decking that you plan to use for years. Treated timber is resistant to damage from moisture, rot and pests, all of which are common challenges in outdoor environments. Unlike untreated wood, pressure-treated wood retains its structural integrity, making it an ideal choice for fencing and decking.
- Weather Resistant
Outside structures such as fencing and decking need to be able to face the elements without damage or excessive wear. Pressure-treated timber goes through a preservation process where chemical preservatives are infused into the wood fibres to help the wood withstand harsh weather conditions such as heavy rainfall, frost, UV rays and more.
- Cost Savings
A well-built fence or decking with treated timber components will require fewer repairs and replacements over its lifespan, reducing maintenance costs and inconvenience. By choosing pressure-treated timber, you can minimise the need for costly repairs or early replacements, ultimately saving you both time and money in the maintenance of your fence.
- Versatility
Pressure-treated wood is highly versatile and comes in many formats. It can be used for a range of applications including decking boards and posts and fencing rails, posts and panels. At Timber Pro, we offer a vast selection of pressure-treated timber so we’re confident that we will have the products you need to help your project succeed.
- Sustainable
If you are conscious of your impact on the planet, then seeking out sustainable ways of living is likely a priority. At Timber Pro, we work alongside certified suppliers who provide sustainably sourced timber. What’s more, all pressure treatments use environmentally friendly preservatives, making it a sustainable choice.
- Aesthetics
Pressure-treated timber can also enhance the visual appeal of your fencing or decking. With a wide range of options available, including different wood species and finishes, you can enjoy results that complement your property’s style while still meeting performance requirements.
- Minimal Maintenance
Pressure-treated wood requires minimal maintenance compared to untreated wood. While you may need to wash it once in a while and reseal it occasionally, pressure-treated wood needs little more than that to keep it looking great for years. If you’re looking for low-maintenance decking and fencing, pressure-treated timber is the way forward.
- Added Safety
If you have children or pets, pressure-treated timber is a smart choice for your decking or fencing. Pressure-treated wood is less likely to splinter, crack or weaken over time. This means that you can relax with the peace of mind knowing that your fencing or decking isn’t a risk to anyone in your household.
- Longer Lifespan
On average, pressure-treated wood can last for over 20 years, even in challenging outdoor conditions. This extended lifespan is a key reason why it’s such a popular choice for outdoor projects such as decking or fencing. What’s more, high-quality, treated fencing and decking can add long-term value to your property.
Using pressure-treated timber for your fencing or decking comes with a huge range of benefits.
