Hear the difference.

Play the video to hear the sound difference before and after installing this system. For best results try to match the volume of the unreduced audio to the volume of the noise you’re able to hear.

The noise in the video has been digitally reduced to give you an idea of the sorts of results you could expect. Unfortunately, this is not a perfect science and your personal results could vary due to myriad reasons. However, we have found our customers prefer to hear a decibel reduction rather than read it!

We stand for quality, and we are proud of it.

MuteBoard® 4 Internal is a wall soundproofing system that seeks to either install MuteBoard to an existing stud frame, or the creation of new ones to split up an area into multiple rooms. Where the available depth of room is at a premium, MuteBoard® 4 Internal will help to retain this while producing a high performing acoustic barrier against common household or workplace noise issues.

This combination of stud framework and MuteBoard® 4 will help to reduce raised airborne noise issues that standard plasterboard or acoustic plasterboard will not be sufficient in reducing. This system also includes Acoustic Mineral Wool to be fit between the studs, at no less than 45kg per m3, and use of Isolation Strips around new timber or metal frames to separate it from adjacent surfaces that could be prone to causing Flanking Transmission.

It is all these materials combined that make it ideal for ‘future-proofing’ against noise issues that could be found in the common household or workplace, or between existing rooms that suffer from intrusive background noise levels.

How to soundproof an existing stud wall

A quick and relatively low-cost option to soundproof an existing stud wall is to install soundproof wall panels. If the stud wall has no existing or very lightweight insulation it should be replaced with high-density mineral wool. Next, you can apply your MuteBoard 4 soundproof wall panels directly to the stud frame. We would recommend using 80mm Hammerfix Screws for this.

Soundproofing wall panels

The MuteBoard 4 soundproof wall panel is made up of four layers of soundproofing material. Two layers of mass-loaded vinyl, a layer of closed cell foam and a layer of acoustic plasterboard. This high mass panel weighs over 25kg per m2, adding mass is a great method for reducing nosie vibrations

Wall Stud Center

The wall stud center is the distance between stud uprights. The typical stud upright is 600mm. If you are working directly on a brick wall we recommend using a 600mm spacing here also.

Wall Channel Center

The wall channel center is the distance between the horizontal MuteClip Channels. The typical channel center is 600mm. If you are working directly on a brick wall we recommend using a 600mm spacing here also.

  • If you have multiple adjacent surfaces or partitions to soundproof input them individually. Not as a total m2 input as this will affect the results.
  • If you have windows, fireplaces or other fixed structures we recommend booking a call with us before purchasing.

A soundproofing system isn’t rocket science but sometimes figuring out which one is right for you can be challenging. Check out our FAQs, get in touch via our live chat, or give us a call to speak to a human.

Noise issues and lack of privacy in the home can induce all different levels of stress, from sleep deprivation to verbal conflicts. We often find that the majority of noise issues that people describe around this topic is nothing more than common sounds that a house would expect, it is just that some homes are poorly insulated against sound that they pass almost freely through what is called flanking paths, and of course directly through partitions – walls, floors and ceilings. A significant amount of UK housing stock built or converted into apartments before the introduction of Part E Building Regulations in 2003 would provide little to no soundproofing and would not require any further works for it is not a retrospective action.

MuteBoard® 4 Internal is a focus primarily on conversion projections as it is uncommon to find new builds using frameworks to separate dwellings, although not unheard of for it is a cheaper method of building. With these current partitions there would usually be a simple framework with thermal insulation and standard plasterboard applied to either side, so when installing this system – a vast improvement is to be expected in the reduction of sound to reinstate privacy and the reduction of neighbour noise. These can also be installed in single dwellings to improve the soundproofing between bedrooms and bathrooms (best installed on the outer of the stud frame and not facing into the bathroom because of moisture, or a moisture board can be installed over the top to protect that acoustic plasterboard layer.

Noise issues in the workplace can be incredibly distracting; this can hinder productivity and concentration – we have written in detail on a focus for office workplace environments here. For conversion partitioning or existing partitions, our MuteBoard® 4 Internal will yield a dramatic improvement over simple building materials often put in place, especially when all cavities are treated adequately, both in the next partition wall and adjacent surfaces – walls, floor and ceiling voids. For when acoustic privacy in quiet environments is required, doctors surgeries, human resource departments in the conducting of interviews or even gym wellness areas – we would make use of MuteBoard® 4 Internal to retain space where possible if there are limitations in this area.

Part E Building Regulations are required for all new conversions and new builds, unless there is a scenario to which any particular circumstance exempts you from requiring to (where you will want to speak your Building Control or Council Officer) such as listed building status – you will need to have your building project pass each target. It may only be that conversion projects would concern using an internal framework to separate dwellings in this scenario, and rarely new builds expect for Houses of Multiple Occupancy. MuteBoard® 4 Internal as a full system being MuteBoard® 4  installed on both sides of the frame would in the majority of cases pass the Part E Building Regulations – but you will want to make sure this is installed in conjunction with adequate soundproofing on its adjacent surfaces to prevent the failure of an acoustic test through flanking transmission

Depending on the age and thickness of the stud frame, this will often determine whether it can support the additional weight of MuteBoard® 4. Timber and metal frameworks less than the 75mm may require replacing or strengthening to support this extra weight – you will also need to consider the importance of the Acoustic Mineral Wool installed here when tallying up the total weight.

Specialist structural engineers (if it is a large project) may be consulted during the large scale surveys to consider the broader aspects of construction when adding significant weight, local joiners with experience will also most likely be able to advise on smaller home projects. If there is any sign of damage such as cracking or bending – then we recommend replacing the frame. New stud frames will also benefit from the use of our Isolation Strip to provide decoupling from the surrounding surfaces, helping to reduce immediate vibration transfer.

Just as above, this all depends on the thickness of the stud frame, but the principle of applying Acoustic Mineral Wool to any cavity is to make sure you do not compress between two surfaces, these two surfaces, for instance, is between the two plasterboards on a stud frame. Forcing in acoustic insulation of 200mm into a 100mm cavity is not beneficial and will create an immediate path for the sound to travel through. Air gaps are helpful when coupled with an insulating material as it allows it to absorb noise found in the cavity. The rule here is to have at least a 10mm air gap on either side, so if the stud frame is 100mm in thickness, use a 75mm Acoustic Mineral Wool.
