MuteBoard® 3 Plus | Masonry Wall Soundproofing

Combining Tecsound and our MuteBoard® 3, this system is another option for direct fitting to brick and block walls. This upgrade is for addressing everyday noise issues in homes and workplaces.

  • Airborne: DnT,w + Ctr = 48dB
  • 29mm

MuteBoard® 3 Plus 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 Plus 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 that with any muffled conversation or any other low-level background interference, these are going to be reduced. MuteBoard® 3 is a dense, multi-layered board comprising of three material types, each bonded together to create an acoustic barrier, and these are combined with Tecsound, a visco-elastic material, this reduces vibration and breaks down sound energy by turning it into heat. 



  • Easy to install, a little background in DIY or joinery would be beneficial.
  • System thickness from the existing wall 29mm
  • 46dB* for airborne (where a higher number is desired) (details are available on the 'System Performance' tab above).
  • Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland)* (details are available on the 'System Performance' tab above).
  • Do not fix this system over Dot and Dab plasterboard.
  • 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 brick or block 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 noise).
  • Tecsound - a visco-elastic barrier to help reduce vibration and improve the reduction of airborne noise.

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.
  • Apply Tecsound SY70 with adhesive backing to the wall (do not peel off front meshing).
  • 9 Hammer Frame fixings into each MuteBoard® 3 over the top of the SY70, leaving a 2-5mm gap from adjacent walls, floor and ceiling.
  • Fix the 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*

  • Muffled conversation
  • Muffled TV and standard radio noise

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

The housing stock in the UK ranges from homes that were built from dense materials where their natural resistance to airborne noise was high to the 1970s and 1980s where densely populated structures were constructed with cheap building materials. Some of these were also not in the time frame of Part E Building Regulations, 2003 and beyond, where soundproofing was required, these offer poor acoustic performance against even the most conservative of neighbours. Neighbour noise is a significant trigger for conflicts and can cause great tension and stress in living conditions, especially if sleep is interrupted, or your sensitivity to sound is high, these can be brought on by even the most familiar of noises expected in the home - made worse by excesses like listening to music at unsociable hours, practising music instruments or the slamming of doors. MuteBoard® 3 Plus is a slim solution to reducing these fundamental noise issues, with the addition of Tecsound this helps to provide a damping layer to the structure while being dense to reduce airborne noise issues, great for patching up walls that may be lightweight like breeze block. We would use this combination of materials in rooms that offer very little space to accommodate any separation or decoupling, and where noise is detected at a muffled level, and you desire to reduce to a more comfortable level.

MuteBoard® 3 Plus offers the world of soundproofing a useful slimline option that applies to any internal application and this is no different for commercial and industrial soundproofing projects that cannot provide the premium of space of our stud systems or MuteClip®. A few examples of where this system can be fitted is between rooms that are separated by weak block work between internal office spaces to improve acoustic privacy, with those requiring higher levels this system can be applied on both sides of the wall, medical facilities is an excellent example for the introduction of such system, for partitions also found in manufacturing areas that need noise from background levels of operating machinery reduced.

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. With wall constructions that are either planning to be of a lightweight block or currently failing airborne results by a significant amount of 5+ dB, it is usually best to use a separating system like our MuteClip® at least on one side of the wall, especially if the noise issue is in the lower frequencies. We would advise discussing these matters with a testing engineer to look at suitability as in some cases we have seen a good uplift from the MuteBoard® 3 Plus

The age and condition of the wall essential for it to will need to be both stable and free from gaps or cracks in the mortar or brickwork, Tecsound is a self-adhesive application, so if the wall is crumbling the sheeting may pull off this layer and fall off the wall. When the wall level deviates by a significant amount throughout this will make it very difficult to install MuteBoard® 3 directly 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 its support of MuteBoard® 3 Plus.

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, this is something you will need to prepare for. If dot and dab plasterboard are present on adjacent walls you will want to consider removing this as installing MuteBoard® 3 and Tecsound up to this will no provide full coverage and thus leaving gaps for sound to travel. The two cavities left on the adjacent walls 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)
