MuteClip® (Patent Pending) Double Plus is our most popular option for projects that require a wall soundproofing solution that is both high performing and space-conscious, with only an 80mm loss of space. It creates fewer points of contact with the partition wall using the 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 layer of SoundPlank 19mm, Tecsound, and a dense layer Acoustic Plasterboard 15mm suspend away from the partition wall. What this ultimately results in is 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
  • System thickness from the existing wall 78mm
  • 64dB* for airborne (where a higher number is desired) (details are available on the 'System Performance' tab above).
  • 10dB - 18dB estimated improvement* over brick wall constructions (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 transmission. (Details are available on the 'System Performance' tab above).


MuteClip® Double Plus is available for specification 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 as a retrofit 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® Double Plus. 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® Double Plus 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); 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/block work 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

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

  • MuteClip® fixed to the brick/block
  • 100mm overlap on MuteClip® Channel with four self-tapping screws into the shoulders of the  MuteClip® Channel, running parallel with the joists.
  • Rockwool RW3 30mm behind MuteClip® Channels
  • The first layer of SoundPlank 19mm 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
  • A sheet of Acoustic Plasterboard 15mm 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.

*Our guide price includes all acoustic materials and ancillaries required

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*

  • Television, light music levels
  • Clear Conversation
  • 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.
  • It is also compliant with the required acoustic values for airborne transmission featured in the Building Standards Technical Handbook 2017 for Scotland, and we would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on an Acoustic System. Scottish Building Regulations contain higher targets than that of Part E, and 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 there are space issues there can also often be a limit on what can be achieved in this amount of space. But, our MuteClip® and Channel with a dense and effective 3-ply system of Acoustic Plasterboard and Tecsound, accompanied with a treatable void to improve performance come in at only 80mm. There is a significant reduction of a good portion of everyday household noises that include: day-to-day conversation, raised television levels and small impact noises such as light switches and light vibration. We look to see an improvement over a single course brick wall of around 10-15dB or a 50-67% reduction as a guide, properties do differ from one another and there would also need to be a great deal of consideration on Flanking Transmission and the paths the sound will take as an alternative to direct trajectory through a wall.

They will be reduced, yes - although without complete separation the low frequencies felt from heavy impact noise and sounds generated from high fidelity systems, soundbars or in the odd occasion, full cinema room installations - these scenarios will require a stud frame to be fitted first to gain separation, and adjacent surfaces will need further consideration to look at how to prevent Flanking Transmission.

With the correct attention to given to any weak areas, flanking paths from cavities above, below and in adjacent walls and any other possible paths sound may travel - MuteClip® Double Plus will in most cases surpass the Part E Building Regulations in both new builds and conversions, of both internal of a singular dwelling and between separate dwellings. Care must be taken to assure all acoustic materials have been installed correctly.

Making the change over to the use of our MuteClip® from Resilient Bars will cut down on incorrect fittings on site, and costly remedial measures that Resilient Bars can often lead to. If a channel has been overtightened during the installation of Acoustic Plasterboard, it’s suspension is lost, and it could well be bent into the wall - meaning the wall will need to be taken down again, channel removed, and start over. With the MuteClip®, there is not incorrect fittings, as well as this - there are acoustic performance benefits in the lower frequencies that the MuteClip® and Channel offer over Resilient Channels.

The void is suitable for fitting a 30mm or 25mm Acoustic Mineral Wool between the Acoustic Plasterboard and the current structural wall. Treating this void is vital to absorb noise issues in the cavity, a void that contains a sound insulating, soft material is beneficial to the overall acoustic performance.

Rigid surfaces in contact with one another will lead to the short-circuiting of an acoustic system through a way of Flanking Transmission. If the Acoustic Plasterboard is butted up tightly to all adjacent wall, floor and ceiling - any vibration found in these areas will move to the plasterboard layers and disrupting the suspension of the wall. Leave a gap as close to each surface without touching and fill with acoustic sealant.

We always advise removing dot and dab plasterboard for it creates a cavity for sound to continue travelling down and amplifying, fixing over dot and dab could create a double leaf effect, a negative attribute in acoustics. It is also advised to remove any adjacent dot and dab on nearby walls, as bringing the newly created sound proof system up to this will still have voids running down each side for the sound to travel freely.
