4.6.4 Construction Category Requirements
AS 3671 classifies a TNR of > 10 dB up to 25 dB as a Category 2 construction (Table 4.5):
‘Category 2. Standard construction except for lightweight elements such as fibrous

cement or metal cladding or all-glass facades. Windows, doors and other openings
must be closed. TNR of approximately 25 dB(A) is expected.’

AS 3671 classifies a TNR of > 25 dB up to 35 dB as a Category 3 construction (Table 4.5):
‘Category 3. Special construction, chosen in accordance with Clause 3.4. Windows,
doors and other openings must be closed. TNR of approximately 25 and 35 dB(A) is
expected.’

Air conditioning units should be provided for all rooms requiring category 2 or 3 construction
to allow adequate ventilation for occupants while maintaining acoustic performance. For
