Good sound insulation by walls and floors is easily achieved
using the inherent mass and damping qualities of concrete. The need
for additional finishes is minimal, thereby reducing capital and
ongoing maintenance costs.
‘Approved Document E – resistance to the passage of sound
(2003)’ sets out the minimum standards necessary to achieve
adequate sound insulation for dwellings and schools and provides
details of achieving this for walls and floors.
provide high performance separating wall and floor constructions
that are expected to be sufficiently reliable not to need the
pre-completion testing normally required by the Building
The majority of details illustrated in both of these sources are
of masonry and concrete.
Additional guidance is provided by actual test results. For
further information please refer to acoustic
test reports. These comprise of acoustic reports from a
selection of real projects with various floor and partition
solutions and different arrangements of finishes and can be used by
designers as another source to indicate the likelihood of similar
details passing pre-completion tests (PCT).
