Fence boards are wooden boards that are an essential component for a fencing project. They make up the fence panel or fencing run itself and provide security and aesthetic appeal.
Whether you're planning to install a new fence or replace existing boards, it's important to choose the right materials for long-lasting performance. Below, we answer some of the most frequently asked questions about fence boards, covering what to look for, timber treatment options, and how to use them effectively.
1. What Should I Look for When Choosing Fence Boards?
When selecting fence boards, consider the following factors:
- Timber Quality - Opt for high quality timber from well managed forests to ensure correct species and growth time frame. This will affect their appearance, as fewer knots are present in high quality sources.
- Treated timber – Choose timber that has been pressure treated - vacuum pressure treated if possible. This ensures deep penetration of treatment and therefore better protection from rot and insect attack.
- Thickness – Thicker boards provide better durability and resistance against weathering. Avoid thin, low-quality alternatives that may warp or break easily.
- Moisture Content – Kiln-dried timber is preferable as it reduces the risk of shrinkage and warping after installation.
- Sustainability – Choose responsibly sourced timber, ideally from FSC-certified forests, to support sustainable practices.
2. Why is Timber Treatment Important?
Timber treatment extends the lifespan of fence boards by protecting them from moisture, insects, and decay. The most common treatments include:
Pressure Treatment – This process forces preservative deep into the wood, offering long-term protection. It is ideal for fencing that will be exposed to the elements.
Dip Treatment – A more surface-level treatment that requires regular retreatment to maintain effectiveness.
3. How Can I Use Fence Boards Effectively?
Fence boards are part of a fence panel, but can also be bought separately and can be used in various fencing styles and applications, including:
Traditional Featherboard Fencing – Individual boards are fixed to horizontal rails for a strong, classic look. Overlapping boards provide excellent privacy and security.
Customisable designs – Kit form fencing gives end users freedom during installation to customise fences to specific lengths and follow the gradient of the ground, which is ideal for steep boundaries and makes changes in heights easier.
4. How Long Do Fence Boards Last?
The lifespan of fence boards depends on the wood type and treatment applied. Properly pressure-treated timber should make the fence boards last upwards of 25 years, while untreated or dip treated wood may deteriorate within 5-10 years. Also invest in quality fence boards with a long lifetime guarantee to ensure longevity.
5. Can Fence Boards Be Painted or Stained?
Yes, fence boards can be painted or stained as with most timbers, but it's not always the best option. To maintain a good look, fence boards will need to be repainted every 2-3 years which adds to garden maintenance.
If a painted look is desired, it is recommended to:
- Use a breathable, weather-resistant stain or paint.
- Ensure the wood is dry before application.
- Reapply coatings every few years for best results.
6. Can I Replace Individual Fence Boards?
Yes, individual fence boards can be replaced if they become damaged. That's one huge benefit of kit form fencing. Ensure that the new board matches the existing fence in size, thickness, and treatment level. Secure the replacement with appropriate fixings to maintain structural integrity. The colour will of course not match straight away, but as the timber ages it will.
7. Should I Use Nails or Screws for Installing Fence Boards?
Both nails and screws can be used, but screws offer a stronger hold and make it easier to replace boards in the future. Stainless steel or galvanised fixings are recommended to prevent rust.
8. How Far Apart Should Fence Boards Be Spaced?
The spacing of fence boards depends on the design:
Featherboard or Featheredge Fencing – Boards are installed with a 20mm overlap to get the traditional feather edge design.
Picket Fencing – Typically, there is a 25mm to 75mm gap between boards.
Decorative Fencing – Spacing varies based on the aesthetic and functional needs of the fence.
Choosing the right fence boards, ensuring proper timber treatment, and using them effectively will help create a long-lasting and attractive fence. Investing in high-quality materials and regular maintenance will save you time and money in the long run. If you're unsure about which fence boards to choose, consult a reputable supplier for expert advice on the best options for your project.
