A Guide To Building Regulations Part E

Imagine living in a house where you could hear every sound from the outside, rooms above and properties on either side. 

It sounds like a bit of a nightmare, right? 

Well, luckily, there is a set of legal building regulations that are designed to handle the matter of soundproofing to ensure a comfortable environment for everyone.

Overall, building regulations in the UK are designed to ensure the safety, health and welfare of individuals in and around buildings of all types. Part E Building Regulations are specifically designed to address sound insulation and noise control. 

Whether you’re a homeowner, builder or developer, understanding and complying with Part E is crucial to creating properties that provide comfort and meet the necessary legal standards. 

In this article, we’ll take a closer look at Part E Building Regulations, covering the rules in detail and outlining its key requirements. 

Read on for more information…

What Are Building Regulations Part E?

Part E of the Building Regulations focuses on the resistance to the passage of sound within and between buildings. This is crucial when it comes to minimising the impact of noise on an occupant’s quality of life. These regulations apply to both new builds and conversions and set the standards for:

  • Sound insulation between dwellings
  • Acoustic conditions in schools 
  • Noise control in communal spaces 

Part E Building Regulations aims to mitigate noise pollution, ensuring that homes and communal properties provide a peaceful environment.

These regulations are required for:

  • Homes
  • Schools
  • Hotels
  • Apartment blocks
  • Halls of residence and other dwellings

The regulations are made up of several sections which address different environments. 

These are as follows:

E1: Protection Against Sound From Other Buildings 

The first requirement under Part E is E1, the protection against sound from other buildings. This section addresses the transmission of sound between different buildings. This is especially relevant for semi-detached and terraced houses as well as flats and apartments.

Airborne sound insulation measures will be required to prevent noise such as conversations, music or other sounds from passing through the walls and floors. Steps must also be taken to reduce the noise of footsteps, furniture movement or other impacts that may transfer through structures.

This can be achieved by using high-density materials like concrete or specialised acoustic plasterboard to block any airborne noise. The installation of floating floors that contain resilient layers to reduce impact noise is also worth considering. 

E1 ensures that occupants of one building are not disturbed by noise from neighbouring properties, prompting harmony and comfort.

E2: Protection From Sound Within Each Home 

It’s also important to have soundproofing measures that act against noise from within the property itself.

E2 focuses on sound insulation within individual dwellings, this ensures privacy and prevents internal noise from becoming a nuisance. This regulation applies to walls and floors separating rooms within a single home and addresses both airborne and impact sounds, like talking or footsteps. 

This section states that walls must be designed to offer sound resistance, especially between floors and bathroom walls. However, these regulations do not apply to walls that feature internal doors. 

Some practical solutions include the use of sound-absorbing materials such as acoustic insulation rolls between walls and floor joists, installing carpet or rugs to dampen impact noise and considering using double-layer plasterboard to enhance soundproofing further. 

The purpose of E2 is to create a peaceful living space where occupants can enjoy privacy and relaxation. 

E3: Reverberation In Communal Areas          

Communal areas in residential buildings, like hallways, staircases and shared lounges, often amplify noise due to their open and hard-surfaced design. However, by implementing E3 rules, reverberation is limited, making these spaces more pleasant to use and reside in.

Excessive reverberation can make communal areas noisy and stressful to be in. So, this regulation applies to buildings that have shared access such as apartment blocks. 

Soundproofing methods should be applied to all communal areas including stairs, corridors, hallways and entrances to flats and communal buildings. These techniques can include sound-absorbing panels or acoustic ceiling tiles, the use of soft furnishings like carpets, curtains and upholstered furniture that reduce echo and spaces that have been designed with sound-absorbing materials in mind. 

By controlling the reverberation, E3 creates quieter and more comfortable communal environments. 

E4: Acoustic Performance and Conditions In School 

Educational settings can be particularly sensitive to noise so E4 rules ensure that schools maintain a pleasing acoustic environment that is conducive to learning and communication. Every room will need to be designed and built to insulate sound from other areas. 

This includes classrooms, music rooms and auditoriums that need to meet specific acoustic performance standards. This includes requirements for sound insulation, reverberation control and speech intelligibility. 

This can be achieved by using acoustic ceiling tiles and wall panels in classrooms, installing double-glazed windows that block out external noise and creating design layouts that separate noisy areas (like sports halls) and quiet zones (like libraries). 

What Is A Soundproofing Test?

To ensure you’re compliant with Part E Building Regulations, your project will face a soundproofing test. These tests are mandatory, and a professional acoustic tester will use specialised equipment to test for airborne sounds and impact sounds. 

Internal walls, dividing walls, floors and external walls will be tested. 

For wall soundproofing, the result must be lower than 45dB in purpose-built dwellings when it comes to airborne sound. There is also a requirement of 62dB for impact sound. 

In conclusion, Building Regulations Part E play a vital role in creating spaces that are comfortable, private and conducive to well-being. By addressing sound insulation between buildings, within homes and in communal and educational spaces, Part E provides comprehensive noise control standards.

Understanding these requirements, preparing effectively and utilising the latest soundproofing materials and techniques are the key to achieving compliance. Whether you’re construction a new building or converting an existing one, you must always adhere to Part E Building regulations. If not, you may face prosecution and hefty fines. 

With all this considered, Part E ensures your project meets legal standards and provides optimal acoustic performance.
