Fire-rated plasterboard (AU): what it is and how to choose
Searching for fire-rated plasterboard usually means one thing: you’re building or renovating something that needs to meet a fire resistance level (FRL) and you want to get it right the first time.
This article explains what fire-rated plasterboard is, where it’s commonly used in Australia, and how to choose products and systems responsibly (without guessing).
What is fire-rated plasterboard?
Fire-rated plasterboard is a board designed to contribute to a wall or ceiling system’s fire resistance performance when installed as part of a tested system. It typically contains additives and a reinforced core to help it maintain integrity during fire exposure.
Common places fire-rated plasterboard is used
- Garages (especially where adjoining the home)
- Multi-residential walls/ceilings between units
- Commercial tenancy partitions
- Plant rooms, service risers and stairwells
Fire rating is a system, not just a sheet
The FRL depends on the entire build-up: board type and thickness, framing, fasteners, insulation, joint treatment, penetrations and sealing. If you’re working from plans, follow the specified system and don’t substitute products without checking equivalence.
