MuteBoard™ 3 system is a slim wall soundproofing solution, one that is practical for even the most space-conscious projects. As a direct fit system, MuteBoard™ 3 reduces airborne noise through its high mass, as the more substantial the materials the most effective they are at 'blocking' airborne noise. What this means for your soundproofing efforts is with any muffled conversation or any other low-level background interference are going to be reduced. As a firm favourite in our range with those who are working on those space-conscious projects, this system is used for soundproofing homes and workplaces.



  • Easy to install, a little background in DIY or joinery would be beneficial.
  • System thickness from the existing wall 25mm
  • 45dB* for airborne (where a higher number is desired).
  • Compliant with Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland) (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.


Combining essential soundproofing materials.


  • MuteBoard™ 3 - 6mm PE crosslinked foam (closed cell) (provides a slender form of separation from timber to decouple)
  • MuteBoard™ 3 - a layer of 7.5kg per m2 Mass Loaded Vinyl (a high mass for reducing airborne sound)
  • MuteBoard™ 3 - Acoustic Plasterboard (dense Plasterboard option for reduction of airborne sound).

How to Install

  • Make sure the wall is as level as possible using a render on uneven walls, and make sure it is as dust free as possible.
  • 9 Hammer Frame fixings into each Muteboard™ 3 leaving a 2-5mm gap from adjacent walls, floor and ceiling
  • Fix MuteBoard™ 3 with tapered edge vertically
  • Fill all gaps with 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*

  • Raised conversation
  • Raised TV
  • Other household use

Compliance with Part E Building Regulations and Scottish Building Regulations


  • We would advise conducting a Sound Test to survey any planned conversions in existing properties prior to concluding on an Acoustic System when adhering to 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 when adhering to Building Standards Technical Handbook 2017 for Scotland, the Scottish Building Regulations 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

Housing in the UK ranges over a significant time period, some offer great levels of acoustic protection against airborne through using heavyweight materials available at the time like a dense stone cottage, up to the residential blocks using cheap building materials that offer very little protection against noise for the tenants. Neighbour conflicts that concern noise complaints are of the highest and it is a common issue we come across every day. These noises often don't have to be in excess of what you would be familiar with in your own home, for instance, a typical conversation, watching television or in the kitchen preparing dinner - if the house is poorly insulated against sound these noises can be intrusive and somewhat stressful. MuteBoard™ 3 as a directly fixed option helps to provide reduction to background noise levels that revolve around muffled conversation and occasional rise in television, it is important to remember this is designed to be a slim line acoustic option that takes up only 25mm and for noise issues that are heard clearly, a more robust option would be best sought.

The availability of slim acoustic solutions are just as important as those that provide robust options for the total space available will determine what can be installed, unless you undergo structural alterations. Our MuteBoard™ 3 can be used across a range of projects that include separating rooms in doctors surgeries to improve acoustic privacy or in the division of internal workshop spaces that are limited in space. Wherever there is a brick or block wall that requires an improvement without the drastic loss of space, MuteBoard™ 3 is a great option.

Part E Building Regulations are required for all new conversions and new builds, unless there is a scenario to where any particular circumstance exempt you from requiring to (where you will want to speak your Building Control or Council Officer) such as listed building status - you will need to have your building project pass each target. It may only be that conversion projects would concern using an internal framework to separate dwellings in this scenario. We would often advise that on some level a form of separation is provided somewhere in the partition design to reduce the impact of low frequency transfer, depending on the current acoustic results or estimated density of the proposed wall partition (for new builds) it is difficult to come to a conclusion, if these cannot be obtained perhaps combining with our MuteClip® System direct with use of MuteBoard™ 3 as the final finish would be the best approach.

The age and condition of the wall is an important consideration in making sure it is both stable and not containing lots of gaps or cracks in the mortar or brickwork. If the wall is uneven throughout this will make it very difficult to install MuteBoard™ 3 directly to as it is not a flexible product, breaking MuteBoard™ 3 down do accommodate these will open up further airgaps and trapping of sound behind them. A wall will often require patching up and rendering to create a smoother and easier finish for installation. If you are uncertain then speak to a structural engineer to be sure of it's support of MuteBoard™ 3.

You will always want to remove dot and dab plasterboard before installation as it creates a cavity behind it that allows sound to be amplified. This cavity varies depending on the depth of the mortar and the condition of the wall behind it, something you will need to be prepared for. If dot and dab plasterboard is present on adjacent walls you will want to consider removing this as installing MuteBoard™ 3 up to this will not be gaining for coverage of the wall, this will not gain best acoustic performance. The two cavities left on either side will continue to be a clear path to flank sound - If you cannot remove this then you will at least want to cut in the depth of MuteBoard™ 3 and run up to the wall (remembering to leave a 2-5mm gap from MuteBoard to the structural wall and filling with acoustic sealant)
