Our MuteMat® 3 system is an essential, high performing solution for soundproofing timber floors, providing noise control for both home and workplace. This system seeks to improve both airborne and impact noise issues while offering you something slim with an excellent performance against even the most intrusive noises. MuteMat® 3 is a compressible soundproof underlay, and while being dense on the top layer that Mass Loaded Vinyl is present, this offers airborne reduction, and with a closed-cell foam on the base, providing a high impact reduction, these combine with the full system. We recommend the installation of Acoustic Mineral Wool between the joists, at no less than 45kg per m3, and also the placing of Isolation Strips on joists to provide a floating floor. It is all these materials combined that make it ideal for those looking to achieve the reduction of overhearing of a clear conversation and bringing down levels of footsteps to background noise levels, as two examples. 



  • High performing floor soundproofing system.
  • System thickness from structural board 12mm
  • 49dB* for airborne (where a higher number is desired) (Details are available on the 'System Performance' tab above).
  • 46dB* for impact (where a lower number is desired) (Details are available on the 'System Performance' tab above).
  • Compliant with Part E Building Regulations (England, Wales, Northern Ireland and the Republic of Ireland)
  • Be sure to check for 'Flanking Transmission' in adjacent surfaces as these can affect acoustic performance.


Combining essential soundproofing materials.


  • MuteMat® 3 - 6mm PE crosslinked foam (closed cell) that is consistent in structure (provides compression needed in timber builds to reduce impact)
  • MuteMat® 3 - features two layers of Mass Loaded Vinyl (a high mass for reducing airborne sound)
  • Acoustic Mineral Wool 45kg or 60kg per m3 - (essential for reducing resonance between joists, and to minimise noise 'flanking' into other rooms)
  • Isolation Strip P8 - is a deviated, rubbed crumber material to separate from joists (to achieve the best performance against impact and low-frequency noise)

Floor Finish Examples

  • A Carpet finish may go straight over the top, and you will need to use Carpet Gripper Strips around the perimeter of the room to raise your gripper rod
  • Laminate and engineered oak will require a 6mm ply minimum to be bonded to the top to act as a stable base
  • LVT, vinyl, tiled and over fragile and thin flooring types would require a 9mm ply minimum bonded to the top to act as a stable base


How to Install

  • Acoustic Mineral Wool fitted between joists in which it's depth dictates thickness needed, you will want to leave at least a 10mm air gap - DO NOT COMPRESS BETWEEN CEILING AND FLOOR.
  • Isolation Strips self-adhered to top of joists, make sure these are as dust free as possible.
  • Subfloor installed, preferably a tongue and groove flooring as this would provide an airtight seal.
  • Perimeter detail installed, dependent on your floor finish above this may either be Perimeter Flanking Band for hard finishes or Carpet Gripper Strip for woven carpeted finishes.
  • MuteMat® 3 installed as brick bond pattern taping each join.



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.

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 and impact 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 prior to concluding on an Acoustic System.
  • In regards to the Scottish Building Regulations Building Standards Technical Handbook 2017 for Scotland, we would advise conducting a Sound Test to survey any planned conversions in existing properties prior to concluding on an Acoustic System, 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.

Neighbour noise issues are one of the most common disputes that occur, and often it is through not fault of their own. Properties built and converted prior to 2003 would not of had any Build Regulations to adhere to in regards to the passage of sound, so this means that there was an unlikelihood of any or very little soundproofing installed - so when you hear footsteps from above, it is often them going about their daily lives. With the introduction of our MuteMat® 3 system comes a dramatic reduction of impact noise that is clearly noticeable, and we would expect a reduction of 15-20dB, a percentage of 67-75% as a guide. This won’t take into account any Flanking paths such as the adjacent walls, these would require investigating during the search for soundproofing options and often treating, whether at the same time or a later date.

Performance will vary greatly with airborne performance depending on what ceiling partition is currently installed, if any - and also with any Flanking paths down adjacent walls, especially with stud frame partitions and with dot and dab plasterboard. For a large amount of conversion projects there will be a substantial difference in performance with pre-2003 builds and with purely insulated structures. With the full system we would expect to see improvement of between 10-15dB, or 50-67% as a guide.

For small office environments we expect to see common noise issues akin to those found at home, conversation being a major one that can often distract from peoples performance or feel like others are in earshot of occasional private conversations, reducing their right to privacy. Then we have larger environments which may contain open plan rooms with a range of teams all working out of one space with offices above or below. MuteMat® 3 is suitable for both these types of scenarios for both impact and airborne noise reduction.

Wherever there is a cavity we and many other Acousticians will always recommend to treat each with a sound insulating material of acoustic mineral wool to reduce it’s boom-like or whooshing sound, leaving it untreated will allow sound to continue resonating across these areas which affects acoustic performance, and it also allows a clear path for sound to flank in to weaker areas of the structure. Impact noise, although still affected, will still yield a good performance with the MuteMat® 3 in place, but in most cases not to it’s best ability.

With the possible defects that are often found in timber constructions and it’s heavy reliance on acoustics coming with the build quality - it is difficult to determine passing of Part E Building Regulations in conversion projects. If a ceiling partition is already installed you may wish to carry out an acoustic test to survey the build and how it currently performs acoustically - if there is no ceiling partition or a single layer of plasterboard it would be best to install a suspended ceiling system below like the ones from the MuteClip® ceiling soundproofing range to work in conjunction with MuteMat® 3 and it’s airborne and impact noise values. With the planning of a new timber structure we can put together acoustic partition designs with your proposals in mind to look at estimated figures for both impact and airborne noise.

The only example where the installation of MuteMat® 3 as a standalone would be sufficient is to decouple: washing machines, dishwashers and other other appliances that create structural vibration to create a soundproofing platform. Any other situation will not yield any acoustic performance, even if you look to only install in a room the splits in to two below, covering only half will just leave a large void to where sound will flank through

This all depends on structural requirements and protection of any damp getting in to the cavity in moisture heavy rooms like bathrooms or wet rooms. We also have an upgrade as out MuteMut™ 3 Plus which introduces our very dense, cement impregnated chipboard - MuteDeck™ for additional soundproofing against airborne transmission.

All rolled carpets can be pulled directly over MuteMat® 3 without any need for an over boarding, Carpet Gripper Strips will need to be fit around the perimeter of each room to raise the gripper rods to a more suited height. Hard floor finishes such as wood of laminate or engineered would require a 6mm ply minimum bonded to MuteMat® 3 to act as a stable base, and lightweight and delicate floor finishes: parquet, luxury vinyl tile such as Karndean and Amtico, and ceramic tiling for example require a 9mm ply minimum, also bonded to act as a stable base.
