The Scheme
STAGE A8 test sets +robustness assessment
STAGE B22* test sets +
robustness assessment
STAGE CPublication in
Handbook
*A reduced number of stage B test sets would be required for new flanking conditions to existing robust details, and might also be acceptable in the case of some new components of existing robust details

Robust Details:
Till now England and Wales
have been 2nd in the WORLD
in terms of field tested sound
Insulation performance
But there is something new on the horizon
Code for Sustainable Homes
robustdetails
Part E Robust Details
A&AC & The Code
Future Candidate RD Proposals
Considerations by proposers towards The Code:
1. What target level of points is the wall or floor aiming for ?
2. Does it compliment other Code sections ?
3. Robust system approach – multi functional – multi regulatory – multi compliant ?
4. Marketing ?

Part E Robust Details
Ctr – Airborne sound insulation
Taming the tiger
+3, +5, +8dB
• Ultimate airborne performance will be dictated by low frequency performance
• To achieve repeatedly +8 dB the CRD proposers and their acoustic designers will have to focus heavily on 100Hz to 160Hz frequencies
