FFT 1 resilient composite deep battens systems can be used in E-FC-1, E-FC-2, E-FC-7, E-FS-1, E-FS-2, E-FT-1, E-FT-2, & E-FT-3 separating floors.
When used on concrete or steel separating floors such as Robust Detail E-FC-1, E-FC-2, E-FC-7 & E-FS-1, the acoustic battens must achieve a minimum laboratory performance of rd∆Lw=17dB.
When used on timber separating floors such as Robust Detail E-FT-1, E-FT-2, E-FT-3 & E-FS-2, the acoustic battens must achieve a minimum laboratory performance of rd∆Rw+Ctr=13dB and rd∆Lw=15dB.
Resilient battens must have a continuous pre-bonded layer with a minimum height of 70mm.
One advantage of the advantages of the FFT-1 Resilient Composite Deep Batten systems is that services can be installed between battens. However they must not bridge the resilient layer on the battens.
In most instances Robust Detail FFT-1 resilient composite deep battens must be overlaid with an 18mm (min) tongued and grooved board. This is usually chipboard but can be plywood or engineered hardwood flooring. However for Robust Details E-FS-2 a min 22mm flooring board must be used.
A 5mm (min) resilient flanking strips is required around the perimeter of the flooring board to isolate the floating floor from walls and skirting.
It is important that the manufacturers recommendations are adhered to for batten centres.
In timber separating floors such as Robust Detail E-FT-1, E-FT-2 & E-FT-3 a 25mm mineral wool and a layer of gypsum based board with a nominal mass of 13.5kg/m² is installed on top of battens prior to the 18mm (min) tongued and grooved board. This is done to add mass to the separating floor and improve airborne performance.
As with any Robust Detail the correct external wall, separating wall internal wall and ceiling detail must be adhered to. The Robust Detail handbook should be consulted to ensure that the separating wall is compatible with the separating floor and vice versa. The Robust Detail checklist should be used to ensure that details are adhered to throughout each sequence of the build.
All acoustic battens used by JCW Acoustic Flooring have been tested in a UKAS accredited laboratory.
When installed correctly robust details should exceed the requirements set out in Part E of the Building Regulations.
With over 15 years of experience in installing all types of Robust Detail flooring solutions, JCW Acoustic Flooring have the knowledge and expertise to ensure that floating floors are installed correctly giving complete peace of mind.
FFT-1 is a floating floor treatment that has been assessed and approved by Robust Details Ltd.
It is typically made up of an 18mm tongue and groove (T&G) floorboard with a resilient layer that must be continuous and pre-bonded to the acoustic batten.
Acoustic flanking strips are used to prevent the impact vibration from leaking via structural walls and reduce airborne and impact sound.
When used on within timber frame buildings, a layer of plasterboard (nominal 13.5kg/m²) is used along with 25mm mineral wool between battens.
When installing floating floors, it’s crucial to refer to the manufacturer’s instructions to ensure optimal acoustic performance and compliance with Part E of the building regulations.
Guidelines state that lightweight internal walls and internal block walls built off the structural floor must be isolated from the floating floor treatment, walls and skirting with a perimeter edge strip.
If the floating floor treatment (Robust Detail FFT-1) is not completely isolated from the structural slab, soil pipes, door frames and walls, then the acoustic performance of the floor will be compromised.

Here at JCW Acoustic Flooring, we supply JCW 80C and 80T battens, which comply with Robust Standard Detail FFT-1.
Our 80C acoustic battens can be used as floating floor treatments for various floor types, including E-FC-1, E-FC-2, E-FC-7 and E-FS-1. Suitable for refurbishment projects, they can be laid onto timber or concrete floors, effectively improving the transfer of impact sound.
JCW 80T acoustic battens are typically used as FFT-1 treatments for E-FT-1, E-FT-2, E-FT-3 and E-FS-2 separating floors. Such floor types require mineral wool between the battens and plasterboard to help improve the airborne sound insulation.
At JCW Acoustic Flooring, we have been supplying and installing Robust Detail Flooring solutions across the country for more than 15 years and are confident we can help you too.
Our specialists will use only the highest quality FFT-1 compliant flooring products and ensure they are installed correctly, in accordance with the manufacturer’s recommendations. This way, you can trust that the requirements outlined in Part E of the building regulations will be met and exceeded.
