MuteBoard 4 is our highest performing of the MuteBoard series for wall soundproofing, helping to reduce airborne noise.

MuteBoard 4 is an ultra thin, high performing dense material to soundproof a wall against airborne noise within residential, commercial and industrial properties. It is an acoustic four-ply material made of Acoustic Plasterboard, Mass Loaded Vinyl and a 6mm Closed Cell Foam - this lamination of varying soundproofing materials help to break down the sound energy as it passes through them, there is also a provision of a damping layer within the closed cell foam. Suitable for both retro-fits and new builds.


We recommend using the MuteBoard 4 within a system to achieve it's optimum performance.



MuteMat™ 4 is part of iKoustic's MuteRange core - these are products that 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.

How to Soundproof a Wall

When considering Wall Soundproofing, you are looking to increase the mass initially to reduce airborne noise, but to yield the best reduction for high levels of noise you will want to consider using a seperating constructions such as a stud frame.

If you are uncertain of what to look for when soundproofing a wall, you can read our handy guide - A Guide to Soundproofing a Wall by clicking on the icon below.

MuteBoard 4 Information

  • 27mm x 1200mm x 1200mm (1.44m2)
  • For reducing airborne noise through a partition wall
  • Can be applied direct to brick/block wall with optimum performance on a stud frame
  • Tapered edge
  • Plasterboard finish ready fo skim/plaster
  • Compliant with both Part E Building Regulations (England, Wales, Northern Ireland and Republic of Ireland) and Building Standards Technical Handbook 2017 for Scotland for impact transmission.

Timber Construction

  • Use of high density acoustic mineral wool between joist of floor and ceiling to reduce flanking transmission and cavity resonance, stud partitions will also want to treated

Handmade Product

All of our MuteBoard series are handmade at our warehouse and with this there may be some slight overhang - this can easily be trimmed with a stanley knife to make sure the MuteBoard butt up together tightly.

This product contains a high level of mass, if there are any structural concerns you will want to consult a Structural Engineer to discuss your requirements.

This product is part of the following systems:

MuteBoard™ 4 is our best performing singular acoustic panel that can be installed directly to brick and block walls, and can also be fitted with existing or new stud framing of both metal and timber. Each board requires multiple fixings per board and is a great space saving method for sound proofing against low to mid-level noises in the home or for sound proofing an office to where airborne noise is an issue, this includes medium level conversations and or light television use. It can be improved by installing on to a new stud frame fixed away from the existing partition and installing acoustic mineral wool  in the newly created cavity. You can find all systems MuteBoard™ 4 is featured in by clicking on the systems tab next to the FAQs here.

MuteBoard™ 4 cannot be used to sound proof a ceiling, the blue cross-linked foam is not suitable for a ceiling installation where fire regulations are concerned, we have a range of high performing ceiling soundproofing products to suit a range of requirements which you can find here.

MuteBoard™ 4 can be applied in a variety of different ways to help improve the acoustic performance, but it is always recommended to use an acoustic mineral wool between any adjacent cavities to reduce ‘flanking transmission’ which can affect the overall performance. Sound will always find its way to an open cavity if a clear path permits it, going around the MuteBoard™ 4 and appearing in one of these cavities.

MuteBoard™ 4 is a hand laminated product which uses a tack adhesive to bond materials together, it it not suitable for installation with an adhesive as the mass would pull apart the tack, only mechanical fixings are recommended with MuteBoard™ 4.

Mute Board™ 4 cannot be installed on the floor as the acoustic plasterboard may suffer from cracking under pressure and will not help to accommodate any fluctuation in joist height, again leading to possible breaking of materials. We have a whole range of floor sound proofing solutions which you can view here.

Our guidance recommends the use of Nylon HammerFix 80mm when applying to brick and block walls, additional advice from a structural engineer of professional equal would be best sought with if there are any concerns, we do supply these fixings but are not included with the purchase of MuteBoard™ 4.

Reverberation is an issue that affects sound internally and is not related to sound proofing in the sense that it requires something dense to reduce sound moving from room to room - it is about improving the sound in a singular space. A sports hall would be a classic example of reverberation, when somebody speaks they will attempt to shout over the noise to be heard but the clashing of sound as it bounces off the hard and reflective surface leading to speech becoming unintelligible. MuteBoard™ 4 is a dense product that will reflect the sound and will not work against treating this issue, we do offer a range of sound absorption materials to help with this issue in wide range of applications including at home, in the office or in hospitality environments including restaraunts, nightclubs and cafés.

Fixing materials through the MuteBoard™ 4 creates a direct path for the sound to travel back through and could crack the plasterboard in a way that makes it a less effective sound proofing system. With light fixtures and plug fixtures we would recommend where possible to relocate them to another wall with the advice of a registered electrician under Part P of the Building Regulations to ensure the most effective sound proofing. MuteBoard™ 4 has a lining applied over the top ready for skim and plastering, we would recommend the skim plaster layer applied before any decoration as it can be highly absorbent and will help to reduce small air gaps in the system. We recommend the use of Acoustic Socket Box Inserts where any sockets need to be installed.

MuteBoard™ 4 can be installed used for soundproofing wet rooms and bathrooms, but would require the addition of a moisture board to stop direct moisture coming into contact with the acoustic plasterboard and causing possible damage to the material. Seek advice from a Damp or Bathroom fitting specialist before purchasing, we can work with such specialists to ensure the right combination of both sound proofing and damp proof materials are applied. The Cross Linked PE Foam in the MuteBoard™ 4 does not absorb moisture nor is it prone to fungal or other damp related issues that chip foam is exposed to.
