Robust Details Limited (RDL) provides a route to compliance for Part E of the Building Regulations (England and Wales). It may be used as an alternative to on-site pre-completion sound testing and is also recognised in the Code for Sustainable Homes.
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 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.

To build or design to Robust Details, you will need to select the walls and / or floors you wish to use from the Robust Details Handbook. Each Robust Detail has its own Checklist. These are designed to help builders ensure that building work is carried out exactly in accordance with the Robust Detail specifications. They can also be used by Building Control Bodies, new home warranty providers and others.

Whilst RDL makes every effort to ensure that Robust Details are compatible with other standards and regulations, we cannot guarantee this. Builders and designers are responsible for ensuring that their designs and building work comply with all relevant standards and Building Regulations
