Fire ratings for acoustic linings: Exploring the key requirements and design considerations

It is the responsibility of every professional engaged in design and construction to have a thorough understanding of the fire safety requirements set out by the National Construction Code 2022 (NCC 2022). Acoustic linings are becoming a standard component of interior environments as a means of reducing noise levels and creating a healthy and visually appealing work or living space. However, due to their porous or perforated nature, some acoustic linings are more fire-prone than others, so obtaining an approved fire certificate or Performance Solution is crucial.

Fire Ratings for Acoustic Linings: Exploring the Key Requirements and Design Considerations navigates the key fire rating requirements for internal acoustic linings under the NCC 2022, with a focus on Group Numbers. Architects and designers should be aware of the Group Number requirements of different areas within a building and what acoustic materials will likely be compliant with the NCC 2022. Practitioners should also be aware of the relevant fire testing and certification requirements, as well as issues surrounding burning droplets.

• The aim of fire-safe building design is to provide enough time and structural stability to enable building occupants to evacuate to a safe location.
• Burning droplets from wall or ceiling linings carry a significant risk of setting fire to surfaces or combustible materials that are not initially involved in the fire, but they are not considered when determining the fire rating of materials.
