MuteClip® (Patent Pending) Internal Double Plus is our robust and effective option for projects that require a wall soundproofing solution that performs at a high standard and is space-conscious with only an 80mm loss of space when fitting to an already existing stud frame or in addition to the new framework without a brick or block construction. This system 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 dense layer of SoundPlank 19mm, a layer of Tecsound and a layer of dense Acoustic Plasterboard 15mm then suspend away from the framework. 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 a substantial reduction of impact noise and other forms of vibration.

 

 

  • Easy to install, no incorrect fixing or shortages unlike standard Resilient Channel
  • Up to 55dB for Airborne (where a higher number is desired)* (details are available on the 'System Performance' tab above). 
  • 10-15dB estimated improvement for airborne noise (where 10dB is a 50% reduction as perceived sound loudness)
  • Compliant with Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland). (Details are available on the 'System Performance' tab above).

 

MuteClip® Internal Double Plus 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. You can also install this system as a retrofit for those looking to improve existing properties, perfect for soundproofing the home. 

 

At iKoustic 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 resultsCAD 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 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 path), this will be an important 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
  • Loss of space approximate 80mm


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 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
  • 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

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.

Space can often be a significant concern in the home, and when this is combined with the want for optimal soundproofing - it comes with the worry that it cannot be achieved. MuteClip® Internal Double Plus is applied directly to existing frameworks that separate two rooms to provide a high level of soundproofing, or installed to new stud framing that is to break up an existing single room, both will find that treating only the single side of stud framing with this system will yield a high acoustic performance. You will want to have any existing stud framing surveyed before applying the substantial mass that this system has. Airborne reduction between the rooms of any existing walls you are applying this to will yield an estimated 10-20dB reduction of sound as an average across all frequencies, this is a guide figure as each property and individual rooms within properties will all differ in performance and their given Flanking paths will also vary.

Both internal dwelling requirements between rooms and separate dwellings are subjected to Pre Completion Testing, with the installation of MuteClip® Internal Double Plus this has been tested to surpass regulations on a timber framework, but you will still need to consider Flanking paths through adjacent voids, and generally weak soundproofing put in place on all nearby surfaces to where sound can travel through. We recommend following all components featured in the system to assure the best acoustic performance is obtained to achieve Approved Document E.

Resilient Bar systems can be fixed incorrectly in several ways, and we have gone through those in our blog here, but in summary, what you will find is that they are easy to fix incorrectly and this can then make their installation almost redundant in terms of sound proofing. The MuteClip™ system is designed to have no incorrect fixings and, as well as this, an improved overall acoustic figure for reducing airborne noise.

The thickness of sound insulation is all dependent on the frame you are using, what you always want to keep in mind is there should be an air gap of at least 10mm on either side and never to double up or compress a thicker size into a cavity.

We would recommend a 75mm thickness as a minimum due to the additional weight of this acoustic system.

If all rigid surfaces in this system, both Acoustic Plasterboard and SoundPlank are in contact with adjacent surfaces, this could reduce the performance by allows Flanking Transmission through vibration to conduct into the plasterboard layers, short-circuiting the MuteClip® and Channel. Make sure this gap is left and fill with Acoustic Sealant.

At least one side of the framework must be removed so that Acoustic Mineral Wool can be installed appropriately, without this the soundproofing performance will be reduced by giving way to sound travelling into the cavity and resonating
