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.
