Hidden Fix vs Face Fix for Thermo Ash Decking

Jun 23, 2026 6 min read Southgate Timber

When customers choose a premium decking board such as Thermo Ash, the conversation often moves quickly beyond the timber itself and into how the boards will actually be installed. One of the most important decisions is whether to use a hidden fixing system or a face-fixed installation.

In this article

  • What hidden fix means
  • What face fix means
  • Which looks more premium
  • Which suits the project best

What Is Hidden Fix?

A hidden fixing system secures the decking boards without visible screws across the face of the deck. This creates a cleaner and more seamless finished appearance, which is often a major advantage for premium timber decks.

What Is Face Fix?

Face fixing means the boards are fixed directly through the top face of the decking board, typically with visible screws. It is a more traditional method and may still be right for certain projects where practicality comes first.

Why Hidden Fix Often Suits Thermo Ash

Thermo Ash is frequently selected because of its premium visual appeal, and customers choosing it are often looking for a high-end deck with clean lines and a refined finish. Hidden fixing helps support that cleaner, more architectural look.

Final Thoughts

For many premium Thermo Ash decking projects, hidden fix will be the preferred option because it supports the clean and polished result customers often want. Face fix still has its place, particularly where practicality is the priority.
