Approved Document E to the Building Regulations (England and Wales) gives specific acoustic performance requirements for door assemblies in a number of situations.
In “dwelling-houses, flats and rooms for residential purposes” (Requirement E1), a minimum acoustic performance of 29dB Rw is required.
For schools (Requirement E4), a minimum of 30dB Rw is requirement - 35dB Rw for music rooms. Please refer to Building Bulletin 93 for more details on this.
Acoustic Containment is also covered in Section 5 of the Scottish Technical Handbooks and Technical Booklets G and G1 to the Building Regulations (Northern Ireland).
These Approved Documents are not mandatory, they are only guidance. However, they are considered to be the usual means of proving compliance with the Building Regulations.
