Timber Floor

The UK building stock is a diverse range of architectural styles, one that has an expansive history. But, acoustically speaking, these differ with great intensity, and buildings, especially homes, leading up to the 1920s to 1930s were internally constructed primarily from timber joists. We are seeing the rapid conversion of these homes in our inner cities to apartments, shared builds and even offices. Floor soundproofing systems need to be prepared to tackle tasks like Part E Building Regulations, specialist acoustic design targets set by local Building Control and even options for Grade Listed buildings. We are still constructing timber builds today, especially in suburban environments, which still require a level of soundproofing internally. We offer a range of systems that span these scenarios and everything in between.



Depending on the level of soundproofing you want to achieve and whether there are any regulations such as Part E Building Regulations that you need to pass, combining them with our Timber Ceiling Direct is recommended.


To help you understand what the performance means and our additional focus on areas when gathering information for a soundproofing project, viewing more below will expand this for you. These systems will offer options for those looking at three deciding categories: Performance, Cost and Thickness.

All of our systems here are designed for timber joist floor structures, they differ from concrete in that they lack in 'stiffness' and 'mass', both naturally found in concrete buildings. What this means is that a springier, or more resilient/compressible system needs to be in place to reduce impact noise. If you tighten the structure and vastly increase its stiffness by using very dense materials such as MuteDeck™ 18mm and adding what is called 'bracing' to the joists, denser rubber alternatives can be used like our MuteMat® OSF 750-10 Pro. For airborne noise, timber floor partitions lack the weight or 'mass' that is needed to obstruct the sound energy transmitting through the partition. MuteMat® 2 and MuteMat® 3 systems are used to approach both airborne and impact noises due to their compressible and flexible nature, while still adding the 'mass' needed for 'blocking' airborne noise.


In soundproofing, timber joist floors are one of two main building types floor and ceiling partitions. If you are looking for systems that will help with timber floor finishes such as engineered wood, laminate or luxury woods, you will find all of our systems are compatible with wood floor finishes, so you can continue browsing these systems!


Understanding Performance in System Summary

Our system summaries are based on guided figures of the highest demonstrable number for this has what has been achieved. If you are an architect, acoustic consultant or specifier you will find all of our test data relevant to that system under 'System Performance' and complete test data under 'Related PDFs' for comparing different scenarios. 

If you are a homeowner looking to improve the soundproofing or your home, we have given subjective readings in our 'System Performance' to give you further guidance, and we are always looking at how to best represent the effectiveness of our systems so that you feel comfortable in your decision. Talking to our wonderful team and their wealth of experience will help you to clear up any uncertainties you have. We are Creating Quieter Spaces Together.

Airborne Performance Reading | We have included an 'up to' rating supported by taking our test data and applying the correction, we have outlined these in details in our 'Guide to Understanding Acoustic Test Results'. But, if you are comparing systems, with a (-*number) you need to subtract this from the first number as like our example below.


DnT,w (C;Ctr) =61 (-1;-7) dB | = 'Up to 54dB'


Impact Performance Readings | In our impact performance, we have two results depending on how we have tested them, and have tried to keep this as clear as possible. 'Down to *dB' is shown when you are measuring the amount of impact noise transferred. You are looking for a lower number here.


Ln,w =48dB = 'Down to 48dB'


The other is the reduction figure that takes before and after, this is more relevant with concrete floors. We put (reduction) next to 'Up to *dB' this to indicate this. You are looking for a higher number here.


Δ30dB (reduction) = 'Up to 30dB (reduction)'


Additional guidance for understanding system and performance. 

  • Systems are important to understand as a whole because they give the clearest picture. 'Soundproofing Products' are assembled and tested in a system, and this includes the partition, the floor in this case, with all its parts. A single floor mat will almost never provide you with an additional "45 dB reduction" for airborne noise, and will almost certainly include the floor as a whole. 
  • If the number signifying impact results go beyond 40dB, especially for a simple soundproof mat product, you could assume this is an L'nT,w or Ln,w rating, where you look for a lower number. Below this number they could be talking about the reduction, a Δ symbol is usually shown here, a higher number is desired here.


Understanding Costs in Systems

Since the costs can vary, we have based this on a £-£££££ rating. We are basing this on the material costs alone, and with floor finishes and additional fitting not included in this. We do provide installation and cover nationwide - we'd be more than happy to go through the details of this with you by contacting our team!


Understanding Thickness in Systems

Thickness is taking the material depths and noted alongside necessary elements of the structure. For example, MuteMat® 3 will expect an 18mm decking (or above if required) and we have noted this in the text. MuteMat® 3 Pro includes our MuteDeck™ 18mm, a dense and airborne resistant decking so will match up thickness wise. Floor finishes are not included, but generally, with hard floor finishes and our MuteMat® 2 and MuteMat® 3, a 6-9mm ply support decking will need bonding on top to keep the floor stable. Compressible materials such as these will all need some support, and rubber alternatives in timber structures will offer little to no benefit in timber without stiffening the floor.


Acoustic Design and Flanking Noise

We provide Acoustic Design at varying levels, and you can read more about how we provide this to all of our customers, whether you are a newcomer soundproofing their home, or an architect or specifier. A basic level of Acoustic Design is included in all of our projects, this is because every property will offer its uniqueness in passing sound, there is no definitive answer to any project. We know that makes it difficult, but we will help you get to the point of using the best system for soundproofing your timber floor while making sure focus is given to the smaller details. We will investigate with you!


If you are working on new build structures as an architect, acoustic consultant or a specifier, we provide 'Partition Designs' that combine flooring and ceiling (when necessary) systems to showcase potential acoustic performance values. We are able to look at the projected airborne and impact down to the use of a specific joist alongside the layering of our floor soundproofing systems. We are also able to do this with existing builds when we have the previous structure design with the relevant information.


Acoustic Design requires a blend of the creative, scientific and practical approaches to solving the huge majority of issues found in soundproofing. An understanding of everything from neighbour noise to workplace disturbances with how it affects every individual differently cannot be responded by simply adhering to regulations, they must be acknowledged together, whether that is with you, an individual or the workplace as a whole.


Flanking transmission or flanking noise is where sound takes an alternative path, which varies from room to room, and structure to structure. When open cavities great or small or adjacent to the area you are covering, for example, a stud frame below and adjacent to the room of a floor and ceiling partition that is left empty or untreated, that become the next area of weakness. We can help advise on this and the answer can range from installing Acoustic Mineral Wool between the studs to using varying wall and ceiling soundproofing systems to get it under control.
