Our MuteCradle™ 16/30mm system is our fully fitted acoustic cradle system, a high performing and efficient method to achieve an easy to install floating floor system. Creating a floating floor, in the case of soundproofing, is essential when treating excessive impact noise issues and areas where you expect high foot-traffic. One example of where we find high foot-traffic is in workplace environments, where a quiet and private space exists below a communal area, such as a kitchen. The separation created by the MuteCradle™ system by the use of our MuteMat® OSF 750-10 affixed to the base, a dense rubber resilient layer that boosts acoustic performance for the reduction of impact noise. Where airborne noise is concerned, MuteCradle™, as we know, separates from the concrete subfloor, so this helps isolate low-frequency noise by creating an air gap, one that you insulate with Acoustic Mineral Wool. To further improve performance, you have the option to apply any of our flooring range to the cradle. 

 

 

  • High acoustic performance creating a floating floor system allowing sufficient space to run servicing underneath, see our 'System Performance' tab above.
  • Up to 55dB for airborne (where a higher number is desired)* (details are available on the 'System Performance' tab above).
  • Down to 54dB for impact (where a lower number is desired)* (details are available on the 'System Performance' tab above).
  • or Up to 27dB impact reduction (where a higher number is desired)* (details are available on the 'System Performance' tab above).
  • Ability to combine with our floor range to further increase soundproofing
  • Loss of space will vary depending on the dual-height option and batten thickness
  • Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland) and Building Standards Technical Handbook 2017 for Scotland for impact transmission. (Details are available on the 'System Performance' tab above).
  • Be sure to check for 'Flanking Transmission' in adjacent surfaces as these can affect acoustic performance.

 

Another benefit of using MuteCradle™ is it is versatile on uneven concrete floors. It has a dual-height selection with a range of 'packers' to create a level floor, no need for screed, no wait for curing times or large machinery, it can adapt to significant steps and incremental dips. Some projects, especially those that need to specify to the wiring of services through voids, also benefit from the advantage of this system (or our higher MuteCradle for increased voids).

How to Install

  • Floor heights will require some prior consideration for layout, including any servicing that requires to be run underneath.
  • 36mm battens would require 6.6 MuteCradle™  per m2 (based on installation advice below)
  • 46mm battens would require 5 MuteCradle™  per m2 (based on installation advice below)
  • Packers available at 1.5, 3, 6 and 12mm
  • Do not exceed 20mm of packers in each MuteCradle™ 
     
  • Battens advised as above to be installed at 400mm centres.
  • MuteCradle™  installed 450mm centres.
  • Installing Acoustic Mineral Wool between battens.
  • Perimeter Flanking Band around the perimeter of each room to butt floor layers against
  • MuteDeck™  18mm or tongue and groove ply/chipboard installed on top of battens

 

 

Alternatively, we provide Acoustic Installation across the UK to fit all of our systems - they come with a wealth of experience in the field so you can feel comfortable that the right installation methods are being carried out.

All of our systems contain a high level of mass if there any structural concerns you will want to consult a Structural Engineer to discuss your requirements.

*Our Typical Performance Results and Noise Reduction Guidance are provided to indicate the results that have been achieved in previous tests but are not guaranteed to a specific site as multiple factors can affect this.

We endeavour to display the most up to date testing and to manage expectation as best as possible. Please do contact us to discuss your requirements.

Compliance with Part E Building Regulations and Scottish Building Regulations

 

  • When installed under the correct guidance this system is compliant with the required acoustic values for impact transmission featured in Part E Building Regulations; these are applicable across the UK, excluding Scotland (England, Wales, Northern Ireland) and the Republic of Ireland. We would advise conducting a Sound Test to survey any planned conversions in existing properties prior to concluding on an Acoustic System.
     
  • It is also compliant with the required acoustic values for impact transmission featured in the Building Standards Technical Handbook 2017 for Scotland, we would advise conducting a Sound Test to survey any planned conversions in existing properties prior to concluding on an Acoustic System, Scottish Building Regulations contain higher targets than that of Part E, our Legal Requirements section has the required acoustic values.

MuteCradle™ is compatible with all types of concrete construction: block and beam, precast and cast in-situ concrete which makes it a superb option for creating a new subfloor platform that helps to level uneven flooring, soundproof against both impact and airborne transmission, and for when servicing is required to be run out of sight.

MuteCradle™ offers a great alternative for those not wanting to implement a screed finish - it can deal with variations in height both small and large, for those with steps in to other rooms - and creating a completely level soundproof floor. Our MuteCradle™ Packers are available in a range of sizes and MuteCradle™ 16/30 works alongside our 45/60 offering a higher degree of levelling.

For Part E Building Regulations concerning both new build and conversions in concrete structures, MuteCradle™ helps to pass the states impact insulation values, but for airborne additional mass may be required to assist with the airborne values, for example the addition of our MuteDeck™ 18mm, or MuteMat® 3. For new structures we can help your proposal by assembling all components proposed in our acoustic partition design to look at potential acoustic figures for both impact noise and airborne noise. Estimated figure of Ln,w 54 dB is expected.

For office installations MuteCradle™ performs highly for noise issues revolving around impact noise and structural borne vibration, for example large printers in direct contact with the floor creating a loud hum, and it helps to improve airborne by way of separation. The void created then allows server wiring, appliance power supplies and any other servicing to run without having to create additional boxing. The void created is also fit for the laying of Acoustic Mineral Wool and this helps to improve the airborne reduction.

With all these examples, and especially recording studios, audio suites and cinema rooms the MuteCradle™ is providing separation from the structure which reduces points of contact made and helps to improve low frequency transmission of sound, which is problematic when it reaches the structure for it can travel great distances with high energy when reaching such a solid mass. We have specified the use of MuteCradle™ in audio focused environments even when there are not properties below for the lower sound energy can travel through the structural foundations and negate any wall soundproofing you have in place.

Using the 46mm softwood batten recommended with the MuteCradle™ and the maximum height to be created at 30mm riser and 20mm maximum of MuteCradle Packers - this allows for a total thickness of 75mm of Acoustic Mineral Wool - for a 10mm air gap is required to where 100mm would create compression and points of contact.

There should be no more than a 3mm deviation in any point of the subfloors final level for this could leave the a lesser acoustic performance and create stability issues, make sure to use our MuteCradle™ packers to assure the flooring is level.

Depending on your requirements there are a broad range of soundproofing solutions available - if you are uncertain of what you require we can look to provide acoustic testing to assist in acquiring certain acoustic targets that could be in in Part E Building Regulations or feature in Building Control requirements for special circumstances.
