Spotlight On Soundboard One
Soundboard One
The Performance Layer Behind Timber FFT-1 Floating Floor Systems
On timber separating floors, consistency is everything.
Unlike concrete, timber structures are lighter and more responsive to vibration. That makes the acoustic floor layer critical — not only for meeting performance targets, but for ensuring that results are repeatable across multiple plots.
Soundboard One has been developed as the primary acoustic floating floorboard within JCW systems. It forms the structural and acoustic performance layer above resilient battens or cradle systems, delivering predictable results in real site conditions.
It is most commonly used within timber FFT-1 floating floor types, including:
- E-FT-1
- E-FT-3
- E-FS-2
In these constructions, Soundboard One plays a defined and measurable role.
What Soundboard One Actually Does
Soundboard One is not a surface treatment or an add-on overlay. It is a structural floating floorboard designed to function as part of a complete acoustic system.
Its role within the build-up is to:
- Add controlled mass to improve airborne sound insulation
- Provide a stiff, stable deck above resilient supports
- Distribute loads evenly across battens or cradles
- Contribute to the reduction of impact sound transmission
Because its density and performance characteristics are consistent, it can be specified with confidence across different timber floor constructions without redesigning the acoustic layer each time.
Why It Is Paired with Acoustic Batten 80T in FFT-1 Floors
In FFT-1 floor types such as E-FT-1, E-FT-3 and E-FS-2, the requirement is clear: create effective separation from the timber structural deck while maintaining structural integrity above.
Acoustic Batten 80T introduces resilient isolation between the floating deck and the timber joists below. That separation reduces the direct transfer of impact energy into the structure.
Soundboard One then forms the floating deck above the battens.
This pairing works because:
- The battens provide isolation
- Soundboard One provides mass and rigidity
- The system behaves predictably when installed as tested
Generic flooring boards may appear similar in thickness, but variations in density and stiffness can influence impact and airborne performance and long-term deflection. Soundboard One is designed to operate as part of a tested system, not as a substitute component.
In compliance-led builds – particularly those following a Robust Details route – that predictability matters.
One Board, Multiple Applications
Although frequently associated with Acoustic Batten 80T in FFT-1 constructions, Soundboard One is not limited to a single configuration.
It is also used above acoustic cradle systems where:
- Sub-floors are uneven or stepped
- Height adjustments are required
- Levelling and acoustic performance must be achieved together
In both cases, Soundboard One performs the same function: it provides the consistent acoustic and structural layer above the isolation system.
For contractors, this simplifies specification. Once the supporting system is selected, the acoustic deck remains the same.
Designed for Real Installation Conditions
Soundboard One has been developed with practical site conditions in mind.
Key characteristics include:
- Consistent board dimensions for repeatable layouts
- Compatibility with standard installation sequencing
- Suitability for both new-build and refurbishment projects
- Availability in 18mm and 22mm thicknesses to suit loading and batten centres
On multi-plot residential developments, reducing variation between plots can significantly lower the risk of failed tests and remedial work. A consistent floating deck layer contributes directly to that reliability.
What Soundboard One Is Not
Understanding its purpose also means understanding its limits.
Soundboard One is:
- Not a standalone acoustic solution
- Not interchangeable with generic chipboard
- Not a thin resilient overlay
Its performance depends on correct integration within the full acoustic floor system.
A Defined Role in Timber Compliance
Within FFT-1 floating floor constructions such as E-FT-1, E-FT-3 and E-FS-2, Soundboard One provides the mass and structural integrity required above resilient battens.
When combined with Acoustic Batten 80T, it forms a floating floor solution that is:
- Designed for timber build-up
- Tested within defined build-ups
- Repeatable across multiple plots
- Suitable for compliance-driven residential developments
At its core, Soundboard One exists to make the acoustic layer of a timber floor predictable – not theoretical, but dependable on site.
