Fire Rated Walls and Acoustic Rated Walls by James Hardie

Our fire-rated walls and acoustic-rated walls have been developed to assist you in selecting a suitable Hardie™ fibre cement product and choosing a system that will meet your performance requirements. We also have details of the systems available to assist in the material selection.

Hardie™ fibre cement products are classified as non-combustible materials. They also achieve better sound-insulated walls and are slimmer than other traditional walling materials. These thinner walls have advantages in multi-residential, units, motels and other similar projects where maximum floor area utilisation is paramount.

Our two-way fire-rated and acoustic-rated systems can be used on timber or steel frames in residential or non-residential construction, such as:

  • Separating walls in multi-unit residential buildings (intertenancy); or
  • External walls close to boundaries

In terms of the New Zealand Building Code (NZBC) requirements, fire rating is referred to as FRR (Fire Resistance Rating) and is measured in minutes e.g. a FRR 30/30/30 means a fire rating for 30 minutes.
