Sound transmission between homes, is a major problem in the UK which requires serious consideration from both architects and builders. Noise nuisance can be a serious cause of stress, and if not remedied it can affect our health and wellbeing as well as influencing our enjoyment of buildings.

Sound insulation in dwellings is a three-part publication which provides practical guidance for designers, construction managers, construction operatives, and property developers about the requirements of the building regulations.

Part 1 sets out the regulatory requirements and general information. Part 2 gives advice on the correct level of sound insulation when constructing new dwellings.

Part 3 offers practical advice and guidance about constructions that provide a reasonable level of sound insulation between dwellings formed by a material change of use. Where new dwellings are formed in a building as a result of a material change of use, they are subject to pre-completion testing to ensure they comply with the building regulations and any site-specific requirements.

The contents of Part 3 of the guide are:

  • The noise problem.
  • Beginning the process.
  • Altering existing walls to form separating walls.
  • Altering existing floors to form separating floors.
  • Potential conflicts with other regulations and requirements.
  • References and further reading.
