MuteMat™ 2

Our MuteMat™ 2 system is a versatile, high performing solution for soundproofing timber floors. This system seeks to improve both airborne and impact noise issues while offering you something slim and ideal for when floor heights are heavily restricted, or at a premium. MuteMat™ 2 is compressible, while still dense, and is combined in a full system with the use of Acoustic Mineral Wool between the joists, at no less than 45kg per m3, and use of Isolation Strips to provide a floating floor function. It is these properties in this system that make it ideal for reducing the overhearing of conversation at raised levels, bringing levels of footsteps down to background noise levels and even dragging of furniture. 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, and this system is for both homes and workplaces.

 

  • Easy to install, and can be loose laid with use of Woven Carpets.
  • Hard floor finishes can also be installed, please see further down for specific details on how to install successfully.
  • Loss of space approximately 20mm (plus any ply and floor finishes to be installed)
  • Up to 46dB for impact (where a lower number is desired)* (details are available on the 'System Performance' tab above). 
  • Up to 45dB for airborne (where a higher 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). (Details are available on the 'System Performance' tab above).
  • Be sure to check for 'Flanking Transmission' in adjacent surfaces as these can affect acoustic performance.

 

 

Combining essential soundproofing materials.

 

  • MuteMat™ 2 - 6mm PE crosslinked foam (closed cell) that is consistent in structure (provides compression needed in timber builds to reduce impact)
  • MuteMat™ 2 - 7.5kg per m2 Mass Loaded Vinyl (a high mass for reducing airborne)
  • Acoustic Mineral Wool 45kg or 60kg per m3 - (essential for reducing resonance between joists, and to reduce 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 Requirements

  • You can install Woven Carpet straight over the top, but 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™ 2 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. You can contact us on 01937 588 226 to discuss your project.

 

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.

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.

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 before 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 before 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.

Neighbours are not always creating excessive noise, at least on purpose - often properties harbour very little to no soundproofing at all to where each sound appears to be coming through with clarity. There are also properties that have a beautiful exposed floor boarding left from pre Part E Building Regulations where a conversion took place, to where before 2003 there was no regulations in place, and every creak, footstep and conversation is heard - once this would of been a single dwelling, where noise concerns internally were not much of an issue. The reduction of impact noise is noticed almost immediately with in installation of the MuteMat 2 and its associated components to where we would often expect a reduction of 15-20dB, a percentage of 67-75% as a guide. This won’t take in to 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 depend on what is currently installed on the ceiling side of the partition, airborne noise may also find its way down Flanking paths in adjacent walls through dot and dab plasterboard, or stud frame work. But with the vast majority of conversion or general home soundproofing requirements a noticeable reduction is always expected - especially if the cavity was previously untreated. With the full system we would expect to see improvement of between 8-15dB, or 40-67% as a guide, but just as with impact, this does not take into account any flanking down adjacent walls or perhaps pipe work or RSJs.

Expected acoustic issues in offices are very much what you could expect at home, although in some we find large printers, call centre rooms and loud meeting rooms that can often intrude or disrupt work performance, there is also the requirement to retain privacy in certain environments where people can be heard from above with weak ceiling partitions. So the same principles apply as question one and two, we have installed this system across a wide range of commercial offices with resounding success.

Sound insulation in cavities is incredibly important for it helps to reduce the sound from reflecting around in the closed off space - this creates a boom-like resonance and will differ from the size of each cavity. Leaving it untreated lends an even larger gap for Flanking Transmission to follow through, moving in to stud frame walls and boxed off areas throughout the floor. So with this, acoustic results can vary greatly from very little performance to still acceptable - but there is no way in telling these prior. Impact noise is still affected by leaving an open cavity but if the floor cannot be lifted you will see often still see a greater lift in the reduction of impact noise.

In timber constructions it is harder to determine the outcome of acoustic results, especially in conversion projects for when only a floor soundproofing solution is put in place the ceiling can often lets down the overall performance, especially if it is directly attached to the joist work. A suspended mass is often required on the ceiling below such as our MuteClip® ceiling systems. 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. Timber is heavily influenced by many construction elements that can both negatively and positively affect their performance for the passage of sound.

For impact noise and light structural vibration such as creating a soundproofing platform for a washing machine, tumble dryer or dishwasher for example it can work well to provide separation when the remaining floor cannot be soundproofed - this will help reduce immediate structural vibrations. Airborne noise on the other hand will see no improvement with only soundproofing a portion of the flooring.

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™ 2 Pro which introduces our very dense, cement impregnated chipboard - MuteDeck™ for increasing airborne reduction.

All rolled carpets can be pulled directly over MuteMat™ 2 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™ 2 to act as a stable base, and lightweight and delicate floor finishes: parquet, luxury vinyl tile and ceramic tiling for example require a 9mm ply minimum, also bonded to act as a stable base.
