Our MuteMat® 3 Plus system is a high performing solution for soundproofing timber floors, and this system provides 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 compressible, while still dense offering both airborne and impact reduction, and is combined in a full system alongside Tecsound, a visco-elastic material that reduces vibration and breaks down sound energy by turning it into heat. There is also Acoustic Mineral Wool to fit between the joists, at no less than 45kg per m3, and use of Isolation Strips to provide a floating floor function. It is all these materials combined that make it ideal for those looking to achieve the best floor soundproofing possible, to reduce clear conversation, bringing levels of footsteps down to background noise levels and even the use of HIFI audio devices. Although these are noise issues commonly associated with what you find at home, especially in dense-living, multiple dwellings, these disturbances are similar to those you hear in the workplace.



  • High performing floor soundproofing system.
  • System thickness from structural board 16mm 
  • 56dB* for airborne (where a higher number is desired) (details are available on the 'System Performance' tab above).
  • 45dB* 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)
  • Tecsound - a visco-elastic barrier to help reduce vibration and improve the reduction of airborne noise.
  • Acoustic Mineral Wool 45kg or 60kg per m3 - (essential for reducing resonance between joists, and to minimise sound '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
  • Isolation Strips self-adhered to top of joists, make sure these areas 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
  • Tecsound SY70 installed throughout with self-adhesive backing, this can be loose laid but use self-adhesive backing around edges to help provide an airtight seal, taping together joins
  • MuteMat® 3 installed over top opposite direction from joins of SY70, taping together joins



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 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*

  • Clear conversation
  • Reducing television and music noise
  • Regular foot traffic

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.

MuteMat® 3 Plus is made of a four ply structure of that harbours dense, compressible and vibration reducing acoustic properties to vastly improve soundproofing against impact noise issues, even for the most heaviest of footing. Its reduction of footsteps, dropping of objects and moving of furniture, where the scraping of a chair can lead to the whole ceiling going - MuteMat® 3 Plus helps across the board. On what level of soundproofing you will achieve will all depend on your ceiling structure - for example on exposed floorboard above and exposed joist below, found in older structures especially Victorian, a drastic improvement would be made, but sound will often still be an issue with no ceiling in place. For common double plasterboard installations we look to see a 10-20dB reduction overall, 50-67% of noise issues reduced as an average.

Both MuteMat® 3 and Tecsound are dense and flexible, helping to drastically reduce airborne noise issues - Tecsound is also available in a range of upgrades up to Tecsound S100, a 10kg per m2 visco-elastic membrane. We would expect to find that noise issues such as conversation, television and low level music without the use of large high-fidelity systems are reduced to background noise levels in common double plasterboard structures with a 10dB reduction for around the middle to higher frequencies, 10dB is a 50% reduction in terms of loudness levels.

Small office environments like those harbouring private businesses of around 10-25 employees would not be drastically above the noise levels expected in home environments in way of conversation, but it is these that can distract from work performance and leave them exposed for there is a lack of privacy. On the other end of the scale we have larger work environments that have 25+ employees with perhaps the use of an open plan call areas to where many teams could be based - if there are smaller offices and meeting rooms above or below, these noise issues could be problematic. MuteMat® 3 Plus is perfectly suitable for both of these scenarios.

If lifting floorboards is not possible, perhaps for Grade Listed status structures or simple unable to for other reasons - the omission of any sound insulation material in cavities can range from drastically affecting acoustic performance to only a little, but there are a lot of factors that can be at play to determine this also. It is not achieving this best acoustic performance possible, especially where airborne noise is concerned. Impact will see the biggest uplift of the two, but again, not to the same degree as when installed as a full soundproofing system.

Timber structures are subject to great changes over time, bending and buckling of joists, damp and settling in bowed positions - all give way to acoustic performances to some level, especially if there is creaking or movement in the joists, this makes it very difficult to determine Part E Building Regulations and its successful passing without knowing the structure currently. 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. 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.

Tecsound is dense, flexible and malleable, making it a diverse soundproofing product for a vast range of applications. As a visco-elastic membrane it sits between a viscous material and an elastic one - both important for the reduction of vibration, and, because it’s density - helps to reduce airborne noise. So Tecsound in this instance helps bring the further damping of vibrations and addition mass for the reduction of airborne.

The only example to where soundproofing a portion of a room is applicable and successful is as a platform for appliances such as washing machines, dishwashers and tumble dryers to assist in decoupling them from the structure to reduce structural borne vibration. 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 Pro 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.
