This document provides information on acoustic insulation regulations in the UK and acoustic products from CMS Danskin Acoustics. It summarizes UK regulations on sound insulation between homes and other buildings. It also provides product information on underscreed flooring systems, underlayments, overlays, panels, and partitioning products for improving sound insulation and absorption. The document is intended to help specifiers choose appropriate acoustic products to meet regulations.

2. Acoustics: the regulations
Approved Document E 2003
(England and Wales)
Aims to improve standards of sound
insulation in buildings, between homes
or rooms for residential purposes.
Approved Document E must be adhered
to when building houses, flats, schools,
hotels, hostels and student
accommodation.
Requirements in dwellings and
flats

between domestic buildings.

*The definition of a traditional building is a building or part of a building of a type constructed
before or around 1919:
a) using construction techniques that were commonly in use before 1919; and
b) with permeable components, in such a way that promotes the dissipation of moisture from
the building fabric.
Education and BB93 Regulations including 2012 Acoustic Performance
Standards for the Priority Schools Building Programme and Technical
Guidance Document TGD-021-5
The level of acoustic performance required is dependent on the room type but the
common requirement is effective reverberation control, e.g. school corridors require
Class C absorber or above. Class A offers the highest level of absorption and
greatest reduction of reverberation times.
