Approved Document E of the Building Regulations (England, Wales & N Ireland)

Acoustic performance of multi-storey and attached dwellings has never been higher on the agenda. With revisions to Part E for England & Wales, achieving compliance with the regulations is an even more complex challenge than before, particularly when dealing with low frequencies.

Performance Standards

What is Part E?

The revisions to Part E of the Building Regulations 2003 address the noise levels suffered by occupants within multi-storey and attached dwellings, which result from inadequate sound insulation.

Why was Part E revised?

The problem of noise levels has increased in recent years through a combination of heightened expectations on the part of occupiers, more sound producing equipment and above all the poor success rate in achieving the sound insulation standards already in place.

What does Part E address?

Part E of the Building Regulations was revised to address those issues by:

  • Extending the types of constructions covered by the regulations.
  • Setting new acoustic performance levels for new-build and conversion / renovation projects.
  • Dealing with reverberation in the common internal parts of buildings containing flats or rooms for residential purposes.
  • Introducing pre-completion acoustic testing for separating walls and floors.
  • Setting standards for acoustic conditions in schools (also see BB93).

All Monarfloor® products and systems surpass the performance requirements of Approved Document E of the Building Regulations.
