Robust Detail FFT-2 acoustic cradle and batten system

Robust Detail FFT-2 Acoustic Cradle and Batten Systems can be used in E-FC-1, E-FC-2, E-FC-7, E-FS-1, separating floors.

The Acoustic Cradle and Batten Systems must achieve a minimum laboratory performance of rd∆Lw=17dB.

Acoustic Cradle and Batten Systems must have a minimum void height of 50mm.

One advantage of the advantages of the Robust Detail FFT-2 Acoustic Cradle and Batten Systems is that services can be installed between battens. However they must not bridge the resilient layer on the battens.

Acoustic Cradle and Batten Systems are ideal for levelling uneven subfloors.

Robust Detail FFT-2 Acoustic Cradle and Batten Systems must be overlaid with an 18mm (min) tongued and grooved board. This is usually chipboard but can be plywood or engineered hardwood flooring.

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 cradle and batten centres. Please contact us for further advice on 01204 548 400.

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 Cradle and Batten Systems 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.

Frequently Asked Questions

Can we use the Acoustic Cradle levelling system to achieve Robust Detail FFT-2 on wooden floors?

The Acoustic Cradle levelling system is designed for concrete base floors, and as such, only achieves compliance with Robust Details FF-2 when installed on concrete floors.

All the necessary testing to ensure product compliance has taken place using this floor type, so alternate use may be possible but remains currently untested.

For projects involving timber floors, consider our JCW 80T Acoustic Batten System, which can be used on timber sub-floors in both new build and renovation projects.

For more technical information, please see the JCW Acoustic Cradle Systems technical datasheet or contact our team in the office who can offer further technical insight by calling 01204 548 400.

Is the Acoustic Cradle levelling system able to achieve Robust Detail FFT-2 with renovation products?

Absolutely. The Acoustic Cradle levelling system is ideal for renovation and retrofitting projects.

Ageing floors can become increasingly uneven, making installing new subfloors tricky. This is a common issue when ex-commercial properties are renovated into flats or apartments.

However, with the Acoustic Cradle levelling system, you can install a wide range of subfloors and improve sound insulation, creating calm, quiet residential units.

If you wish to order an Acoustic Cradle levelling system from a UKAS-accredited installer, simply email or call us today on 01204 548 400.

Do you need all parts of the Acoustic Cradle levelling system to achieve Robust Detail FFT-2 in a project?

All parts of the Acoustic Cradle levelling system are needed to ensure that the subfloor sits level on an uneven concrete base while providing acoustic isolation and reducing the transmission of impact sound.

The entire system consists of:

  • Acoustic foam
  • Interlocking riser
  • Level pod cradle
  • 2mm packing shims

It is not recommended you try to complete your project without all of the relevant parts, or the correct number of acoustic cradle systems for the subfloor being installed. This will only create a weakened floor that does not provide the promised acoustic qualities promised.

As such, we always recommend checking your requirements with one of our friendly experts before you order- it saves any mistakes that can slow down projects after delivery.

You can call us on 01204 548 400 for specific, experience-based advice on your project’s requirements and to place an order.

Does the Acoustic Cradle levelling system to achieve Robust Detail FFT-2 have any other uses?

Although predominantly used internally to level uneven sub-floors and provide acoustic separation between the base floor, because of the structure of the system, it is also ideal for creating a level base to carry external decking applications, including:

  • Balconies
  • Bridge decks
  • Rooftop decking
  • Pool decking

The JCW Level Pod Cradle System is perfect for structural timber deck boards thanks to its weather, rot, and damp-proof properties, which will help your outdoor timber structure last longer.
