What is a Robust Detail?
A Robust Detail, for Part E of Building Regulations, is a separating wall or floor construction which has been assessed and approved by RDL.
In order to be approved, each Robust Detail must:
- be capable of consistently exceeding the performance standards given in Approved Document E to the Building Regulations for England and Wales.
- be practical to build on site.
- be reasonably tolerant to workmanship.
Robust Detail designs are pre-tested to higher standards than those required by Approved Document E of the Building Regulations before being approved by RDL. Therefore, if you build using Robust Details, you won't have to carry out pre-completion sound testing.
