MuteClip® (Patent Pending) Double is our most popular option for projects that require a wall soundproofing solution that is both high performing and space-conscious, with only a 75mm loss of space. It creates fewer points of contact with the partition wall 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 two layers of dense Acoustic Plasterboard 15mm and Tecsound suspends away from the partition wall, ultimately resulting in an 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 74mm
  • 62dB* for airborne (where a higher number is desired) (details are available on the 'System Performance' tab above).
  • 10dB - 20dB 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 transmission. (Details are available on the 'System Performance' tab above).



This systems performance can be further increased to achieve additional reductions in sound and vibration transmission, please ask a member of staff about these options if you require additional system performance.


MuteClip® Double 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. 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 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/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

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® Channels, running parallel with the joists.
  • Rockwool RW3 30mm behind MuteClip® Channels
  • 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.

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.

As our most commonly selected and popular system for it’s compact size to acoustic performance, something that does not encroach on living space when looking at wall soundproofing options for the home - MuteClip® Double provides the best of both worlds. It will help to reduce common household noise from conversations found in the background and at raised noise levels, light television usage and even reduction of light vibration from light switches and boiler rooms. With an existing single course brick wall, we expect to see a reduction of approximately 8-15dB or 40-67% as a guide; this will not take into consideration Flanking Transmission or sounds coming from an unknown location.

Although there will be a reduction in the middle to high frequencies, the low frequencies may still be problematic once installed; this is because to mitigate these we would need to implement a stud framing as a way of achieving complete separation from the structure. A lot of low-frequency energy is generated with these activities and noise issues, so if these are the main concerns, checking flanking paths and looking to install our MuteClip® Stud Double would be the best option.

With all considerations given to flanking paths and making sure that adjacent surfaces have been adequately soundproofed too, the MuteClip® Double would help to surpass Part E Building Regulations for the airborne insulation requirements in both conversions and new builds, for internal dwellings and separate dwellings. We are able to create acoustic partition designs with new build constructions and add layers together to see estimated acoustic figures, and with conversions - an acoustic test can be carried out to survey the structures current acoustic performance.

Resilient Channels can, unfortunately, be fit incorrectly in many ways, and with each of these comes the failing of an acoustic system, or if there are requirements such as Approved Document E or any other special acoustic requirements, these will lead to failure and the replacement of them. MuteClip® and Channel require one fixing per clip, and the Channel snaps merely onto the row of clips which are spread out, all acoustic materials are then fitted onto the MuteClip® Channel. It also offers superior acoustic performance over resilient bar with special focus on low-frequency mitigation.

MuteClip® and Channel creates a 41mm void between Acoustic Plasterboard and the structural wall, so a 25mm or 30mm Acoustic Mineral Wool is best placed here to allow an air gap to operate. Do not attempt to compress a thicker size in, this will negatively impact the system by short-circuiting the acoustic clip and bar.

Hard surfaces that are butt up together tightly are susceptible to receiving vibration through Flanking Transmission, something that can affect the acoustic performance of any system dramatically. Always leave a gap to the adjacent walls, floor and ceiling to as close as you can get without touching and line with Acoustic Sealant.

Dot and dab is a soundproofing myth, it’s creation to improve acoustics is a little misunderstood, and most homeowners tell us that the sounds can be heard from everywhere - this is because there are small paths that allow the sound to flow freely. They should be removed where possible, or at least cut into to allow the new wall sound proofing system to come close to the actual structural wall.
