Overview

The partition has been designed as a soundproofing solution for new builds or existing structure conversions. The soundproof partition is designed in line with Part E of Building Regulations. The systems and products chosen provide a good level of attenuation in transmissible sound when used together as part of this acoustic partition. These build up's have been created using knowledge and expertise gained over our 10 years in the business, backed up with acoustic test data in order to ensure compliance with Part E.

 

Components

The base of most of our soundproof partitions is formed using our tried and tested MuteClip and MuteClip Channel products. These products help to de-couple surfaces and acoustically isolate internal surfaces from structural elements. The clip features a dual impedance silicone isolator, designed to reduce sound and vibration transmission over a wider range of frequencies compared to a single density isolation clip. Fixed to the MuteClip Channel are two layers of high density acoustic plasterboard. The mass and sound reduction of these layers can be improved by sandwiching them with a central layer of Tecsound SY70 for a further increase in mass of 7kg/m² and additional vibration dampening effects. Within the cavity we recommend filling using 60kg/㎥ acoustic mineral wool. Mineral wool helps to absorb sound and to reduce the ability for the sound to amplify and travel throughout the cavity. The back of the studwork is covered with another double layer of acoustic plasterboard.

Part E Partitions

These partitions make it easier for the both client and specifier during the specification phase of a project. This selection of partitions/systems have consistently achieved the required performance levels to pass the legal requirements of Part E of building regulations. These partitions/systems have also been curated to ensure that they are cost effective for the client with reassurance to the specifier as we have had consistent results with these systems on site.

 

The Partition can be specified on a wide range of projects that include large scale residential builds, commercial properties such as separating office partitions for increased privacy, and even audio recording and audio editing environments that are limited in space. This system is also suitable for retrofits for those looking to improve existing properties, perfect for soundproofing the home. 

 

Projects where you are specifying the use of the partition. We can provide Acoustic Modelling Data for estimating results, CAD drawings of the MuteClip® and Channel to aid visualisations, and fantastic rates so that you feel you're making the right choice. We also provide Acoustic Testing for existing structures as well as Part E Building Regulation testing and additional acoustic testing options for projects that include: Gyms and Nightclubs or even homes that require or seek increased acoustic performance for improved living quality.

The Partition contains components from our MuteRange core - these are products that have been subjected to stringent testing in both laboratory and real-world environments providing the best possible solution for the purpose with a result you can trust.

Compliance with Part E Building Regulations and Scottish Building Regulations
 

  • When installed under the correct guidance this system is compliant with the required acoustic values for airborne and impact transmission featured in Part E Building Regulations; these are applicable across the UK, excluding Scotland (England, Wales, Northern Ireland) and the Republic of Ireland. We would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on an Acoustic System.
     
  • It is also compliant with the required acoustic values for airborne and impact transmission featured in the Building Standards Technical Handbook 2017 for Scotland, and we would advise conducting a Sound Test to survey any planned conversions in existing properties before concluding on an Acoustic System. Scottish Building Regulations contain higher targets than that of Part E, and our Legal Requirements section has the required acoustic values.
     

  • For additional guidelines and requirements for non-residential buildings; for example, Gyms, Nightclubs and Industrial focused purposes, please do contact us so we can discuss your available options.

What is Part E?

Part  E is mentioned a lot in soundproofing and throughout our partitions. Put simply part E refers to the guidelines and requirements for buildings in relation to the transmission of sound. This could be sound transferring between the floors of apartments / flats, or noise travelling between properties in terraces and semi-detached dwellings. All new builds and converted properties must comply to Part E for both airborne and impact sound in order to pass building regulations. Part E is used to ensure people have some degree of peace and quiet in their home with the majority of the population living in close proximity to other households. While these guidelines help in ensuring some level of sound reduction between properties they define the minimum requirements for compliance, not necessarily a good level of reduction in sound transmission. 
 

What is a Part E partition?

A Part E partition is a partition designed using our industry knowledge and soundproofing expertise to provide a simple and effective solution to passing Part E of building regulations for the UK. Combining elements of our single side systems into a full partition soundproofing solution provides a great level of performance while keeping down costs and depth down to a minimum.

 

What's the difference between airborne and impact sound?

All sound is created through vibrations in a medium, this could be through any material, surfaces, walls or through the air itself. The difference between the two ratings refer to the original source of the sound.

- Airborne sound is sound that travels through the air before transferring through a partition, classic examples of this is speech, music, dogs barking, TV sound etc. 

- Impact sound transmits directly through an impact with a partition, this is most commonly caused by footsteps from people or pets.

While types of sound will fall into one of these two categories all sound is simply a form of vibration therefore it's often the case that both of these values will be affected by a sound source. Sources that cause direct vibration should also be considered and isolated where possible such as a washing machine spinning, speakers etc.

 

How do I soundproof a partition?

Soundproofing a partition is done through considerations on four main areas, that help to reduce the transmission of sound through partitions such as walls and floors:
 
Decoupling - Decoupling involves the separation of layers through a medium or method of fixing, by creating a separation between layers through high impedance materials vibrations have a much harder job transferring through to internal or external layers.
 
Mass - Adding mass to a partition reduces the sound transmission through materials, this relates to mass law, stating that for a total doubling of a partitions mass will reduce sound transmission by approximately 5dB.
 
Layers - Using multiple layers of different densities help reduce sound transmission. As  the sound wave travels through the different densities the power of the wave is impeded. 
 
Absorption - Products such as mineral wool absorb sound waves and transfer the kinetic energy to heat energy, reducing the level of sound transfer. Absorpitive materials can also be used within a space to control echo and reverberation. 
 
Soundproofing partitions can be done  in a variety of ways, the process can often get confusing and may be hard to initially understand. We offer tailored advice and planning for any project from small domestic projects, music studios and large new build projects. The best option if to email or call us with information about the project and we can help explain the process and guide you through the options available for your specific requirements
 
 

How does this system compare to resilient channel soundproofing?

Resilient channels have been used extensively in soundproofing for many years. While they can perform reasonably well, this relies on them being installed correctly and consistently throughout. Many issues can arise if installed incorrectly, when channels are installed upside down, screws tie surfaces together or the internal layers come into contact with other surfaces at junctions. The MuteClip and Channel can be used as a direct replacement for resilient bar installations and offer a higher performance, more straightforward installation and with much less opportunity for an incorrect installation.
