Fire and Acoustic Design Manual

This manual provides information about James Hardie two way fire and acoustic systems using timber or steel frames in residential or non residential construction, such as:

• Separating walls in multi unit residential or commercial buildings
• External walls close to boundaries

In terms of the New Zealand Building Code (NZBC) requirements, fire rating is referred as FRR (Fire Resistance Rating) and is measured in minutes e.g. a FRR 30/30/30 means a fire rating for 30 minutes. Further explanation regarding this is provided in section 7.6 of this technical specification.
