MuteBoard 3 l

Specialist Soundproof Plasterboard for Part E Building Regulations Compliance

If you have a noise-filled home or workplace that you are looking to bring peace to, with a solution that you can apply in various ways, whether it is a room tight for space, or something that is acoustically more effective than standard plasterboard techniques, then our MuteBoard™ 3 is perfect.

MuteBoard™ 3 is slim and practical, and this means that you can use it from anything for the reduction of ambient noise levels when applied directly to brick, block or stud frames, or even raised noise issues that can range from intrusive conversation to televisions when installing on an isolated stud frame.

MuteBoard™ 3 is slim and practical, and this means that you can use it from anything for the reduction of ambient noise levels when applied directly to brick, block or stud frames, or even raised noise issues that can range from intrusive conversation to televisions when installing on an isolated stud frame. To achieve the best possible solution for soundproofing, you will need to incorporate them into what is called ‘Systems’, and it is here you will find MuteBoard™ 3 in a range of options. These offer ways of increasing acoustic performance by fitting them to decoupled stud frames, internal stud frames to split multiple rooms, or when you need to be conservative with space by directly installing them to your brick/block wall.


  • 1200mm x 1200mm x 25mm.
  • A hand-made product that may require trimming off excess.
  • For improving issues with airborne noise for walls only.
  • Application to both concrete and timber structures.
  • Easy to apply a plaster skim layer directly
  • 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 impact transmission.*

Whether you find noises that are a nuisance or are disrupting your home environment, or you are looking to specify our range to put together a solution for a workplace environment that is effective and easy to install, MuteBoard™ 3 will help to overcome these.

As a three-ply soundproof material, MuteBoard™ 3 comprises of a layer of six millimetres closed cell foam that provides a separating layer from the surface, a Mass Loaded Vinyl layer at four millimetres in thickness to provide damping, this means that due to its flexible mass it will help to break down vibration energy positively from rigid materials. Finally, we bond these to soundproof plasterboard that is ready for skim and plastering. You will find acoustic plasterboard throughout the soundproofing world, and we incorporate this into many of our acoustic systems and products, and it is its increased mass over standard plasterboard that makes it more efficient.

MuteBoard ™ 3 is part of the MuteRange core – these products are 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.

MuteBoard™ 3 is our readymade, hand-laminated acoustic panel that can be easily installed direct to brick and block walls and can also be fitted to improve standard stud walls both of timber and metal frameworks. Each board requires multiple fixings per board and is an excellent space-saving method for soundproofing against low-level noise at home or to soundproof an office, and it is best used for when airborne noises are an issue which includes the reduction of low to middle volumes of conversations or reduction of television usage. You can improve MuteBoard™ 3 by installing on to an additional separate stud frame fixed away from the existing partition and use of acoustic mineral wool to treat the air space.
MuteBoard™ 3 should not be used to sound proof a ceiling, and the blue cross-linked foam is not suitable for a ceiling installation where fire regulations are concerned, we have a range of ceiling soundproofing options available as alternatives. With Fire Regulations, you will want to discuss the use of our acoustic materials with Building Control so that they can be signed off appropriately.
Soundproofing upgrades are available for MuteBoard™ 3 to help improve the overall acoustic performance, but it is always recommended to use acoustic mineral wool between any adjacent cavities to reduce ‘flanking transmission’. Sound will always find its way to an open cavity if a clear path permits it, going around the MuteBoard™ 3 and appearing in a new location.
MuteBoard™ 3 is only loosely bonded to keep each component together, ready for fixing – it cannot adhere to the wall with adhesive, for this reason, the mass would compromise the safety of installation. Only mechanically fix MuteBoard™.
MuteBoard™ 3 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. We have a whole range of floor soundproofing options which you can view here.
Our guidance recommends the use of Nylon HammerFix 80mm when applying to brick and block walls, and we advise additional advice from a structural engineer for any concerns, we do supply these fixings but are not included with the purchase of Mute Board™ 3.
Reverberation is an acoustic issue that is concerned with the internal of a room and is not related to sound proofing in the sense that it requires something dense to reduce sound moving from room-to-room, but focuses on improving the sound within the room. A sports hall would be an example of reverberation, when the tutor would attempt to shout over the class but the clashing of sound builds up as it bounces off the hard and reflective surface making it unintelligible. MuteBoard™ 3 is a dense product and will not work in this case, and we offer a range of sound absorption products to help with this issue.
Fixing materials through the MuteBoard™ 3 creates a direct path for the sound to travel back through and could potentially crack the plasterboard in a way that makes it less effective. For 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 best possible soundproofing result. MuteBoard™ 3 has a lining applied over the top ready for skim and plastering, and 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.
MuteBoard™ 3 can be installed used for soundproofing bathrooms and wet rooms 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, and 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™ 3 does not absorb moisture, nor is it prone to fungal or other damp related issues that affect chip foam. We do not supply damp proof materials.

Installation Guide

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™ butts up tightly together.

You will want to make sure that the surface you are applying to is flat to avoid any joints unsuccessfully matching up. A rendering of walls will help to not only create a level wall but to patch up significant gaps in the mortar and create a stronger surface to apply MuteBoard™ 3.

When affixing MuteBoard™ 3, you will want to use heavy duty fixings with 9 per board and remember to leave a 2-5mm gap from the adjacent surfaces.

Fix MuteBoard™ 3 with tapered edge vertically.

Fill all gaps, including the abutting of all joints and around the perimeter. The aim to make sure the surface is as airtight as possible as you are trying to reduce airflow that airborne noise transfers through, even the smallest of gaps.
