What is Slatted Timber Fencing?

Slatted fencing is created using evenly spaced timber battens (often PAR – planed all round timber), installed either horizontally or vertically to create a modern, linear appearance.

It’s commonly used for:

• Garden boundaries
• Privacy screens
• Outdoor zoning (e.g. separating patio areas)
• Decorative feature walls

Choosing the right timber is essential for both appearance and long-term performance and here are the best timber options for slatted fencing:

• 18 x 38mm PAR

Horizontal vs Vertical Slatted Fencing

Horizontal Slats:

• Most popular modern style
• Creates a wider, more open feel
• Ideal for contemporary gardens

Vertical Slats:

• More traditional, structured appearance
• Can make spaces feel taller
• Often used for feature sections

Choosing the Right Batten Size

The size of your timber battens will impact both the look and performance of your fence.

Common choices:

• Slim profile battens (approx. 18 – 20mm thick, 42 – 45mm wide) create a sleek, modern look
• Narrower battens offer a lighter, more subtle design

Spacing tip:

• 5 – 10mm gap = more privacy
• 20mm+ gap = more light and airflow

Installation Considerations

To get the best results from your slatted fencing:

• Use stainless steel fixings to prevent staining
• Ensure proper spacing for airflow and drainage
• Install on a suitable subframe for stability
• Consider applying a treatment oil to maintain colour over time
