How to Choose and Install Closeboard Fence Panels – Standard vs Heavy Duty
Closeboard fencing remains one of the most popular and durable choices for residential and commercial garden boundaries in the UK. Known for its classic appearance and impressive longevity, closeboard panels offer privacy, wind resistance, and a solid sense of security—making them the go-to solution for homeowners, landscapers, and contractors alike.
But when it comes to choosing the right product for your project, many customers find themselves weighing up the differences between standard and heavy duty closeboard fence panels. Understanding these options, as well as how to properly install them, can help you make the right investment for your garden or site.
At Clarke Fencing, we supply a full range of closeboard fence panels in pressure treated brown or green finishes. Whether you’re building a private garden boundary, enclosing a driveway, or replacing worn fencing, this guide will help you understand the key differences and how to get the best results.
What Are Closeboard Fence Panels?
Closeboard fence panels are made up of vertically overlapping feather edge boards fixed to horizontal back rails. The panel is usually enclosed in a timber frame for added rigidity, and each one measures a standard 6ft (1.83m) wide.
Why Choose Closeboard Over Lap Panels?
Compared to traditional lap panels, closeboard offers:
-
Far superior strength and wind resistance
-
A more attractive and traditional finish
-
Longer lifespan with proper installation
-
Compatibility with timber or concrete post systems
They are particularly suited to exposed gardens, shared boundaries, and perimeter fencing, where durability and privacy are key.
Standard vs Heavy Duty Closeboard Panels
Standard Closeboard Panels
Standard panels are ideal for everyday residential use where the fencing is not exposed to harsh weather. They are lighter, more economical, and easier to handle—yet still built to a high specification.
-
Constructed from quality feather edge boards and horizontal rails
-
Pressure treated for rot resistance (available in green or brown)
-
Great value for money
-
Suitable for most domestic gardens
Heavy Duty Closeboard Panels
Heavy duty panels are reinforced with additional back rails, thicker framing, and superior fixings. These panels are ideal for high-wind locations, commercial applications, or customers who simply want the most robust fencing possible.
-
Enhanced framing and construction for maximum durability
-
Increased weight and thickness
-
Designed for longevity and harsh environments
-
Commonly used by professional landscapers and developers
What You’ll Need to Install Closeboard Fencing
Installing a closeboard fence takes more than just panels. Here’s what you’ll need for a solid, long-lasting result:
Fence Posts
Posts are the foundation of your fence. You’ll need one post per panel, plus one for the end of the run. Allow for at least 2ft (60cm) burial depth for stability.
Posts should be spaced at 1.83m centres to match panel width.
Gravel Boards
Gravel boards raise the panel off the ground, prevent rot, and give a clean visual line.
Post Mix and Protection
-
Postcrete – Fast-setting concrete mix (use 1.5 to 2 bags per post)
-
Post Saver Sleeves – Prevent timber rot at ground level
Installation Tips for Closeboard Fence Panels
1. Measure Your Boundary
Divide the total length by 1.83m to calculate the number of panels. Add one extra post for the end.
2. Dig Post Holes
Make holes approx. 60cm deep and 20–30cm wide. Use a post level and string line for alignment.
3. Fix Panels Between Posts
-
With timber posts, use brackets
-
With slotted concrete posts, slide the panel and gravel board into place
We recommend:
-
Standard Fixing Clips
Use 4 brackets per panel for security.
4. Use Pre-Fitted Capping
All closeboard panels at Clarke Fencing come with a pre-installed panel cap, giving a finished appearance and protecting the panel from rain. No need to add extra capping.

If you’re working on a typical garden project and want something strong, neat, and budget-friendly, our standard closeboard panels are a great choice.
