Certificate No: EW687A

Designed to ensure compliance with Approved Document E – Noise, the appropriate solution for an individual floor will

always be designed by InstaCoustic.

The C40 and C60 cradle systems are designed for use on new build, material change of use and refurbishment projects and

both level and uneven timber and concrete floors.

Robust Detail FFT2 also covers the use of this system.

The Cradle and Batten floor system is usually installed in conjunction with an acoustic ceiling such as the AC/90/1

(EINS/309/005, EINS/309/008 for concrete floors) or AC90/2FP (EINS 309/006 for timber floors) metal ceiling system

incorporating acoustic hangers. Alternative details are also available if a fire resistance in excess of 30 minutes is required.

The Cradle and Batten can also be used as a dual flooring system with the system 208. This may remove the need for a

specific acoustic ceiling but such applications should be consulted with the InstaCoustic Technical Team.

Resilient flanking strip must be applied around perimeter of floor to seal and isolate from structure. Mineral wool insulation can

be installed between the battens for improved acoustic performance. Pipes in services must not come into contact with the

timber battens or chipboard floor, this would cause a direct transmission path. Ceiling to be fitted before the dry-lining on the

walls to improve performance. If dot & dab is used, the centres of the dabs must be in accordance with the regulations. Light

weight wall constructions can cause flanking sound transmission which may bypass the floor solution.

Floor receiving the cradle and batten system must be hard, dry, free of all debris and reasonably smooth.

If a screed has been applied it must be fully cured before beginning the installation of the cradle and batten system.

Building to be dry and weatherproof before installation.

All flooring materials to be stored in safe dry conditions.

Instacoustic adhesive and sealant should not be subjected to temperatures of less than 5°c.

All beam and block or concrete plank floors should be fully grouted.

If the cradle and batten system is to be subjected to abnormal loading, it may require the use of hard and/or additional cradles.

In such cases refer to the InstaCoustic Technical Department for advice.

Services running at the perimeter of the room must be a minimum of 150mm from the perimeter, and should not be grouped

any wider than the available space between the battens.

Always seek advice from the InstaCoustic Technical Team regarding suitable solutions.
