MuteClip® (Patent Pending) Internal Double is our slim and effective option for projects that require a wall soundproofing solution that performs at a high standard and is space-conscious with only  a 75mm loss of space when fitting to an already existing stud frame or in addition to the new framework without a brick or block construction. It creates lesser points of contact with the stud frame using our MuteClip®, which is composed of a dual-density rubber in a galvanised metal case - acting as a shock absorber. The MuteClip® Channel affixes to the MuteClip®, and the new soundproof wall which is composed of a single layer of dense Acoustic Plasterboard 15mm suspends away from the framework, ultimately resulting in a vastly improved reduction of airborne noise, especially in the more problematic lower to middle-lower frequencies, as well as reducing immediate vibrations.

 

 

  • Easy to install, no incorrect fixing or shortages unlike standard Resilient Channel
  • Loss of space 75mm when fitting to an existing stud frame.
  • Up to 52dB for airborne (where a higher number is desired)* (details are available on the 'System Performance' tab above).
  • 10-12dB estimated improvement for airborne noise* (where 10dB is a 50% reduction as perceived sound loudness)
  • 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 airborne and impact transmission. (Details are available on the 'System Performance' tab above).

 

MuteClip® Internal Double can be specified on a wide range of projects that include large scale residential builds, commercial properties such as separating office partitions for increased privacy, and even audio recording and audio editing environments that are limited in space. This system is also suitable for retrofits for those looking to improve existing properties, perfect for soundproofing the home. 

Projects where you are specifying the use of an acoustic system our team can help you from start to finish and with the use of our MuteClip® Internal Double. We can provide Acoustic Modelling Data for estimating results, CAD drawings of the MuteClip® and Channel to aid visualisations, and fantastic rates so that you feel you're making the right choice. We also provide Acoustic Testing for existing structures as well as Part E Building Regulation testing and additional acoustic testing options for projects that include: Gyms and Nightclubs or even homes that require or seek increased acoustic performance for improved living quality.

 

MuteClip® Internal Double contains components from our MuteRange core - these are products that have been subjected to stringent testing in both laboratory and real-world environments providing the best possible solution for the purpose with a result you can trust.

MuteClip® System vs Resilient Channels

We have provided a detailed blog on the use of our MuteClip® System against the 'Additional Costs of Resilient Channel.' 

"To make you aware of the potential issues and additional costs Resilient Channel can leave within the project, we have provided some brief points to review before proceeding with this method."

Making sure you are prepared

  • Conduct prior sound testing or home testing to draw attention to any potential flanking paths (where sound takes an alternative route), and this will be an essential part of making sure you have the best soundproofing in place and managing what is possible to achieve, our team can help guide you on this.
  • You will need to make sure you are fixing directly into the brick/blockwork and not fixing over existing plasterboard (this may require levelling before installation)
  • To lay Acoustic Mineral Wool between flooring and ceiling joists to help reduce flanking transmission
  • Loss of space approximate 75mm


How to Install

Installation is based on a 600mm spacing, and we recommend staggering the MuteClip® at 1200mm in a diamond configuration with a MuteClip® at each end. MuteClip® Channels would also installed with a 600mm spacing with one located 100mm from top and bottom

  • If the framework is not already installed, this would require fixture with Isolation Strips to maintain maximum separation.
  • MuteClip®  fixed to the framework
  • 100mm overlap on MuteClip® Channel with four self-tapping screws into the shoulders of the MuteClip® Channels, running parallel with the joists.
  • Rockwool RW3 between the framework.
  • The first layer of Acoustic Plasterboard fixed on to MuteClip®  Channel with self-tapping screws (leaving a 2-5mm gap from any adjacent surfaces and using acoustic sealant)
  • A layer of Tecsound SY70 adhered with self-adhesive backing to Acoustic Plasterboard
  • The second layer of Acoustic Plasterboard fixed on to MuteClip® Channel with self-tapping screws (leaving a 2-5mm gap from any adjacent surfaces and using acoustic sealant)
     

 

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 are 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

Noise Reduction Guidance*

  • Raised Television, light music levels

  • Minor impact noise issues and vibration
     

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 airborne 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 before concluding on an Acoustic System.
     
  • Regarding Scottish Building Regulations we would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on this Acoustic System as they contain higher targets than that of Part E, our Legal Requirements section has the required acoustic values.
     

  • For additional guidelines and requirements for non-residential buildings; for example, Gyms, Nightclubs and Industrial focused purposes, please do contact us so we can discuss your available options.

To where space is a concern, MuteClip® Internal Double can be applied to just one side of a framed partition and will offer a high level of noise reduction, so whether you are improving an existing framework between two rooms or looking to create two rooms from an existing single room, MuteClip® Internal Double would be ideal. With any existing stud framing, you will want to have this surveyed before applying a substantial mass to it, it may be that its age or thickness is too weak to support these additional weights. Airborne reduction between rooms with an existing typical internal stud of two layers of standard plasterboard would yield a 10-15dB, a 50-67% improvement as an average across all frequencies - this is given as guidance and does not take into account any potential Flanking Transmission that can affect the overall performance.

When referring to Part E Building Regulations for interior rooms in a single dwelling, Part E Building Regulations would highly likely be adhered to in this scenario, as long as all Flanking Paths have been considered and adequately soundproofed. The same goes for the use of stud framework to separate two dwellings with the installation of MuteClip® Internal Double making sure all required components are installed correctly and Flanking Transmission paths dealt with sufficiently. This system has been tested as a framework in settings that showcase its performance going beyond the acoustic requirements set out in the Approved Document Part E.

In the installation phase of fixing Resilient Bar a number of incorrect fixings can lead to the failure of acoustic performance, we have seen them fitted the wrong way up to where the bar sags and bends leaving the Acoustic Plasterboard touching the floor, to them being overloaded and again, resulting in the Acoustic Plasterboard touching the floor. They have been over tightened and crushed the channel, and the fixings have breached the channel, and a direct path from wall to plasterboard is created, reducing the flexibility in the wall. The Mute Clip™ acoustic clip and channel system cannot be incorrectly fixed, and the design lends itself to being foolproof, no matter what experience you have in DIY. It also offers an acoustic improvement over the performance of Resilient Bars.

Depending on the thickness of stud frame work, this will determine your Acoustic Mineral Wool thickness. MuteClip® and Channel offers a 41mm isolation gap between the stud frame and 1st layer of Acoustic Plasterboard. So in frameworks of 50mm, a 75mm thickness would be sufficient, and a 100mm for the 75mm thickness of the framework. Remember not to double up on Acoustic Mineral Wool and compress it into a gap smaller that it’s total thickness, an air gap of at least 10mm is required to prevent creating a path for sound to travel.

We recommend a 50mm stud framing minimum, but a 75mm would offer better support overall - existing frameworks should be investigated before installing the MuteClip® Internal Double for any issues with support such as age or any existing cracking or bending.

With any rigid surfaces in direct contact of tight butting such as the Acoustic Plasterboard to adjacent surfaces, this will lend itself vulnerable to Flanking Transmission and vibration transferring back into the system itself, negating the acoustic clips set up to provide suspension.

Yes, existing plasterboard will require removing at least on one side to fit Acoustic Mineral Wool throughout, without the installation of sound insulation the cavity will continue to resonate and the acoustic performance will be lessened.
