Acoustic Cradle & Batten (C40 & C60)

The versatile cradle and batten system with unique, patented, recycled rubber crumb cradles comply with Robust Detail FFT2. Widely used where Pre-Completion Testing is required and in refurbishment and new build projects, these systems can be levelled on-site to eliminate variations in the structural floor surface and can accommodate services.

Increasing Floor Heights

When increased finished floor heights are required, to cater for specific design criteria, deep services or very uneven sub-bases, cradle base packers or deep cradle battens are available for rapid, cost-effective height adjustment. The cradle base packers may be used in multiples to achieve the desired finished floor height. Deeper battens are generally used in larger projects and where a consistent high void is required.

Access Runs

Access runs can easily be created by the introduction of removable boards cut to suit. Ensure that the access run boards and adjoining floor boards meet in the centre of a batten and that the access boards are supported by the introduction of cross-battens located with the cradles. Additional battens and cradles may be required to suit the position of the access runs.
