Acoustic performance

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.

Robust Details 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 Regulations.

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).
