Raised acoustic floating floor system - C30, CK30, 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 Height

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 and desired finished floor height. Deeper battens are generally used in larger projects and where a consistant high void is required.

Example: Multiple Cradle Base Packer Assembly

Example: Interlocking Cradle Base Packer Assembly for Increase Elevation

Example: Deeper Cradle Battens for Increased Elevation

Finished Floor Heights

Note:

CK30 uses 18mm or 22mm plywood. C60 uses 22mm chipboard.
Cradles can be packed to within 5mm of the top of the cradle to achieve maximum floor height adjustment.

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.
