Part E of the Building Regulations in England and Wales focuses on the resistance to the passage of sound within buildings. It sets out requirements to ensure that buildings are designed and constructed to minimize noise transmission between and within dwellings, as well as between buildings and adjoining properties. Part E of the Building Regulations is designed to ensure that buildings provide a comfortable living environment by limiting the transmission of noise both within and between dwellings. Compliance can be achieved either through sound insulation testing or by using approved construction methods known as Robust Details.
Scope of Part E
Dwelling-houses, Flats, and Rooms for Residential Purposes: Part E applies to new builds, conversions, and extensions, including flats, houses, and rooms intended for residential use (e.g., hotels, hostels).
Common Areas: It also covers common areas of buildings containing flats or rooms for residential purposes.
Schools: There are specific provisions for sound insulation in schools.
Requirements
E1 - Protection Against Sound from Other Parts of the Building and Adjoining Buildings:
This requirement ensures that walls, floors, and stairs that separate different dwellings or rooms within a building have adequate sound insulation to reduce noise transmission.
E2 - Protection Against Sound Within a Dwelling-house, etc.:
Applies to walls and floors within a single dwelling to minimize noise between rooms.
E3 - Reverberation in the Common Internal Parts of Buildings Containing Flats or Rooms:
Addresses the need to control reverberation (echo) in common areas, like corridors and stairwells, to prevent excessive noise.
E4 - Acoustic Conditions in Schools:
Sets standards for internal acoustics in school buildings, ensuring classrooms and other spaces provide an environment conducive to learning, free from excessive noise.
Performance Standards
Sound Insulation Testing: Buildings must undergo sound insulation testing to ensure they meet the standards set out in the regulations.
Design and Construction: The regulations specify construction techniques and materials that can be used to achieve the required levels of sound insulation.
Compliance
Pre-Completion Testing (PCT): In most cases, sound insulation testing must be conducted on a sample of the building to demonstrate compliance before completion.
Robust Details: Alternatively, builders can use pre-approved construction details known as "Robust Details" to avoid the need for PCT, provided these details are used exactly as specified.
Technical Guidance
The regulations provide guidance on achieving the necessary sound insulation through various construction methods, including masonry, timber frame, and steel frame constructions. Detailed specifications are given for floor and wall constructions to meet the required standards.
It is a requirement of Part E that all sound insulation tests are performed by a competant person who is a member of a recognised third party such as the ANC or a UKAS accredited organisation (including SITMA). Contact us today to arrange your test.
