This three-part Good Building Guide provides practical guidance for designers, construction managers and operatives, and property developers on understanding the requirements of national building regulations concerning the provision of sound insulation in dwellings.

Part 2 explains how to provide a reasonable level of sound insulation between new dwellings. New dwellings are subject to routine sample pre-completion testing to ensure that they comply with the minimum performance targets in the appropriate national building regulations and any site-specific requirements.

The regulatory requirements and more general information are provided in Part 1 of this publication. Part 3 will give advice on providing the correct level of sound insulation for converted dwellings.
