A review of Building Regulations Approved Document E: Sound Insulation & Sound Testing for Part E of the Building Regulations -
Posted in Soundproofing & Sound Testing on Feb 10, 2018
An important part of the national building regulations are the various approved documents within it. These approved documents give guidance to designers, developers and engineers as to how building regulations can be met in common building situations. As such, they give a vital point of reference when building properties that people in the industry can rely on. Interestingly, there is no legal obligation to adopt the solutions presented in the Approved Documents as the national Building Regulations can be met in other ways if preferred.
What is Approved Document E?
This document was last published in 2015 and deals with sound insulation. More specifically, it is concerned with the resistance within a property to the passage of sound. It gives advice on the requirements for sound insulation in both new dwellings and dwellings that have been converted from other types of building.
The scope of the document covers sound reduction between different rooms in residential terms as well as specific rooms in a dwelling. Acoustic conditions for common spaces in schools or flats are also covered too.
What specific areas is guidance given for in Approved Document E?
This document is made up of a total of 9 different sections. The areas they cover include:
Section 0: Performance
Section 1: Pre-completion testing
Section 2: Separating Walls and associated flanking constructions for new buildings
Section 3: Separating floors and associated flanking constructions for new buildings
Section 4: Dwelling-houses and flats formed by material change of use
Section 5: Internal walls and floors for new buildings
Section 6: Rooms for residential purposes
Section 7: Reverberation in the common internal parts of buildings containing flats or rooms for residential purposes
Section 8: Acoustic conditions in schools
There are also 5 annexes to the Approved Document as follows:
Annex A: Sets out the way of working out mass per unit area
Annex B: Advice on procedures around testing the installed sound installation
Annex C: Terminology
Annex D: Relevant references
Annex E: Important design detail
What are the key pieces of information contained?
All the above content covered is naturally essential but some may be more commonly referred to than others. The advice on pre-completion sound testing is most useful as it gives guidance on how to perform sound tests on properties as needed.
The sections on the separation of walls and floors comes in very handy also. These give various examples of the types of walls and floors you can use in new buildings along with any junction requirements. Section 4 is referred to when guidance is needed on work to existing areas within a property such as the walls or corridors. Many designers and engineers also find Section 5 most helpful as it provides advice on layout and junction requirements internally in a new property.
