Fire-Rated Plasterboard: Do You Need It for Your Build?

Fire safety is a critical part of any building project — whether residential, commercial, or industrial. Fire-rated plasterboard, also known as fire-resistant or FR board, plays a vital role in slowing the spread of flames and heat, giving occupants more time to evacuate and helping structures meet Australian building standards.

What Is Fire-Rated Plasterboard?

Fire-rated plasterboard is manufactured with a specially formulated core reinforced with glass fibres and other additives. This composition increases its ability to resist fire and retain structural integrity for a longer period compared to standard plasterboard.

When Do You Need Fire-Rated Plasterboard?

• Party walls between townhouses or duplexes
• Walls and ceilings in attached garages
• Multi-residential buildings (apartments, units)
• Commercial projects such as offices and retail stores
• Corridors and fire exit paths

Always check your local building codes or consult your certifier for project-specific requirements. Fire-rated products are often mandatory in class 2–9 buildings under the NCC.

Do Fire-Rated Walls Need Special Installation?
