Online Handbook

This handbook contains the separating wall and separating floor constructions that have achieved the status of robust details for Part E of the Building Regulations (England and Wales), “Resistance to the passage of sound”.

Each robust detail includes materials and construction details for the separating wall/floor and its key interfaces with other elements and should be read in conjunction with Appendix A.

The final page of each robust detail is a checklist,which should be photocopied and used by the site manager/supervisor to confirm that the separating wall/floor has been built correctly. The building control body may ask to see the checklist.

It is important that separating walls/floors and their associated junctions and flanking conditions are constructed entirely in accordance with the relevant robust detail; otherwise the building control body may require pre-completion testing to be carried out.

The tables on pages 4,5 and 6 show which robust detail separating floors and walls can be used in flats/apartments.
