Timber Ceiling

The UK housing stock ranges across an impressive history of architectural styles. What these do present is a great difference in acoustic insulation with buildings leading up to the 1920s to 1930s, especially residential, made up internally from timber joists. Now we are converting these structures in our inner cities to apartments, shared builds and even offices which need to consider adjacent homes with meeting Part E Building Regulations, the suitability of certain uses with Building Control, and at times, options for Grade Listed buildings. With us still constructing buildings from timber today, especially in suburban environments, where there is still a requirement for internal soundproofing for single residences. We have a vast offering of systems for different uses found in our Timber Joist Ceiling Direct.


To help you understand what performance means, electing the right soundproofing for gathering information for a soundproofing project, and guidance on acoustic design, selecting 'view more' below will expand this for you. These systems will offer options for those looking at three deciding categories: Performance, Cost and Thickness.

Acoustic Design         Installation             Sound Test

Timber Joist Ceilings are resilient, or if you will, 'bouncy', and it is for this reason that impact noise and the creaking of floorboards and joists become unbearable, especially in older properties. They also lack any weight which is important for obstructing airborne noise. With Timber Joists there is also the bending, twisting and bowing of them that present complications with installing a successful acoustic ceiling. Our MuteClip® comes in 3 different options, and you will find them under LP (Low Profile for space-saving options) XP (Extended Profile for varying joists heights to create a level ceiling) and there is our standard MuteClip® for those who are working on projects that have none of the above issues. MuteClip® is an excellent choice for projects looking to restore peace and quiet, and for passing a wide range of soundproofing regulations. MuteBoard™ 2 is also available for those who are working with very tight depths for their ceiling. 


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' 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) =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 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 ceiling in this case, with all its parts. Even the most robust systems mat will almost never provide you with an additional "45 dB reduction" for airborne noise, and will almost certainly include the ceiling and 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. 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

With our Timber Ceiling Direct, we are taking the total material depth from the bottom of the joists. MuteClip® XP and MuteClip® LP will present slightly different variances given joist depths and we have displayed MuteClip® XP at its maximum depth of 100mm. We do not include the skim and plaster finish which is often nominal in the total system thickness. 


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 ceiling and floor (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 thickness alongside the layering of our ceiling 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.
