Floating Floors and Under Screed

Homes, workplaces and factories to name a few, are built with concrete, and today this is very common. Concrete offers swift building times with the ability to pre-cast concrete in factories and the capacity to build upwards to save less square meterage on the ground. What this means is that you will find homes, offices and even leisure centres as in these multi-purpose structures. Part E Building Regulations and Building Control requirements for special cases concern a wide range of acoustic issues. It is here we offer systems for creating floating floors and soundproof under screeds for screed applications.


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


                             Acoustic Testing or Sound Testing

Acoustic Design         Installation             Sound Test


Acoustic Floating Floor Systems help to improve airborne and impact noise significantly in concrete builds. Because of the 'stiffness' of concrete, they need resilience and decoupling to see the best soundproofing possible. We offer an acoustic cradle - MuteCradle™ in alternating sizes which doubles up as a floor levelling option, so you won't even need to screed!


Those seeking Soundproof Under Screed Systems, we supply a USF (Under Screed Flat) for space-conscious projects, which is also suitable for Part E Building Regulations up to USP (Under Screed Pimpled) for maximum sound control, each of these floating the screed and improving impact and vibration control and the reduction of airborne noise down to very low frequencies.


Concrete structures are usually constructed of the following

  • Pre-Cast Concrete
  • Poured Concrete
  • Block and Beam Concrete


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 of your home, we have given subjective readings in our 'System Performance' too, 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.

Airborne Performance Reading | We have included an 'Up to *dB' 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) =56 (-2;-7) dB | = 'Up to 49dB'

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 when you are measuring the amount of impact noise transferred. You are looking for a lower number here.


L’nT,w = 53dB = 'Down to 53dB'


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.


Δ 30dB (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 in Floating Floor and Under Screeds is taking the material depths alone, for there are a wide variety of options that are applied to the top. MuteCradle™ is a floor levelling system, so there may be additional packers required in some areas, a choice of 36 or 46mm softwood battens and floor finishes. MuteMute® USP and MuteMat® USF will require different thickness screeds for specific weights being applied and floor finish requirements. We outline each of these on the systems themselves to give you better guidance for each, including compression details in product data for screed under 'Related PDFs'


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 are able to 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 performances of various depths of concrete slabs, whether its pour, pre-cast or block and beam, and we can combine them with our floor soundproofing systems with different thickness of screeds. 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 noise affects every individual differently cannot be answered 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 - no two are alike! When open cavities great, 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 becomes a weak point. We help to advise on these areas and provide options that range from installing Acoustic Mineral Wool between the studs to using varying wall and ceiling soundproofing systems to get it under control.
