Timber Wall

Soundproofing partitions work on a set of principles based on increased mass, de-coupling of rigid layers and dampening or absorption of vibrations. For a soundproof timber or metal frame internal wall it can be difficult to add the level of mass that a masonry wall or similar would provide, and that may not even be possible structurally. Through extensive testing and research iKoustic have developed robust products and systems for internal soundproof partitions by greatly increasing the levels of de-coupling and vibrational impedance. Sound can therefore be reduced far more efficiently than by simply adding mass alone as is often done by just adding acoustic plasterboards to the frame. Through the use of the MuteClip systems a timber wall can be effectively soundproofed to a high level, providing a great separation between spaces or dwellings. If space is limited the MuteBoard systems can instead be installed to help achieve a good improvement on acoustical performance without adding as much depth on to the wall build up.


Stud walls are also a very easy way to divide up a single dwelling but often provide the least robust level of soundproofing. This can commonly cause issues when inefficiently soundproofed timber walls allow a lot of sound to pass from communal areas of the house to bedrooms for example. Part E Building Regulations are a concerning area where adequate soundproofing for timber walls & internal frames is often missed out of the design. These partitions will often be the most noticeable and sometimes the very thing that needs soundproofing most. Workplaces with special focus on commercial offices often create steel-framed internals studs that offer very little resistance for sound, leading to poor performance and disruption to even the most basic tasks. We offer reliable timber wall soundproofing systems for internal wall frames that lack a solid wall construction.


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 timber wall soundproofing systems will offer options for those looking at three deciding categories: Performance, Cost and Thickness.

Internal Stud Frame Walls, although they don't seem much to the eye, will often perform better than a standalone brick or block structure. The lightweight and resilient structure offers better decoupling options and can be less costly, especially if your building needs additional support for dividing walls on the upper floors. When simple drywall plasterboard is installed on either side with very light-weight insulation, as is most commonly found in homes and workplaces, they will have a poor performance. But, by applying any one of our systems on to a single side, or even both sides for better performance, you will be solving a wide range of issues. Our MuteClip® is our decoupling sound isolation clip that features throughout our systems and gives you the best performance as a system, one that protects against vibration and raised airborne noises. On just one side it will offer to soundproof bi-directionally and will be more than sufficient for Part E Building Regulations, as long as all flanking paths have been treated. 


We also have systems that apply our MuteBoard™ range, ranging from only 19mm in depth to 28mm; perfect for projects that a restricted in space but want to provide an overall improvement in combination with Acoustic Mineral Wool. Balancing the reduction of common household and workplace noises and keeping the space lost in each room to a minimum.


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 with 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 *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'


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 stud frame with both sides included in this case, with all its parts. A single product will almost never provide you with an additional "45 dB reduction" for airborne noise, and will almost certainly include the wall partition as a whole. 


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 try to factor in frame costs here, which are often low in material costs. We provide installation and cover nationwide - so we'd be more than happy to go through the details of this with you by contacting our team!


Understanding Thickness in Systems

We are taking the depth from the stud frame here, and not including the stud frame itself as this can vary. Some are already installed and will be sufficient for installing our most robust MuteClip® option to, some will need replacing with a slightly thicker frame, so these can change depending on the system and what is required.


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 the stud frame 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 showcase our Internal Wall soundproofing systems to showcase potential acoustic performance values. We are able to look at the projected airborne performances of different thickness of stud frames and combine them with our wall 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 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 adjacent to the wall that is being soundproofed is left empty and untreated, this will then become 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 floor and ceiling soundproofing systems to get it under control.
