ROBUST STANDARD DETAILS

Robust details are construction solutions which provide an alternative to pre-completion sound testing as a method of complying with the Building Regulations Part E (resistance to the passage of sound).

A robust detail, for Part E of the Building Regulations, is a separating wall or floor construction which has been assessed and approved by Robust Details Limited. In order to be approved, each robust detail must:

  • Be capable of consistently exceeding the performance standards given in The Building Regulations Approved Document E.
  • Be practical to construct on site.
  • Be reasonably tolerant to workmanship.

If you build using robust details, you won't have to carry out pre-completion sound testing but you do need to obtain permission from Robust Details Ltd and pay the fee for each home. Provided that the robust details are built correctly this will be accepted by all building control bodies as evidence that the homes are exempt from pre-completion testing. On completion of each separating floor or wall the builder is required to complete a compliance certificate and pass it to their building control officer. Without this certificate the building control will not approve the construction.
