Notes
- RDs and PCT can be used in the same building. The number of credits awarded should be based on the lower performance. For example, if the floor is subject to PCT and qualifies for 3 credits and the wall is in the RD scheme and qualifies for 4 credits, only 3 credits would be awarded
- Whether PCT or RDs are used it is important to ensure the wall and floor types chosen are compatible. Please refer to tables 3 (a, b and c), 4 and 5 of the Introduction to the Robust Details Handbook
- (P) = Provisional as per guidance in accompanying document
- Top storey flats may be awarded credits based on airborne sound performance of the floor only, noting that flats beneath other dwellings will be subject to both impact and airborne sound transmission. At present, no RD floors produce a different credit rating based on airborne performance only, but such a circumstance is provided for under these criteria
- credits awarded at design stage will be awarded at post construction stage (provided the development meets the RD requirements) even if the credits awarded for the RD in question have changed in the interim
