Maxiwall AAC Fire Rated for Builders and Trade Professionals
Building with Maxiwall AAC Fire Rated Panels is the smarter, faster and cost-saving way for modern home and low-density housing construction. AAC fire rated panels help trades on site with lighter and more time-saving walling installations with better thermal, acoustic and fire-rating performance.
Fire‑Rated, Energy‑Efficient AAC Cladding Systems
Maxiwall AAC wall panel cladding gives professional trades a very high fire‑rating performance that is ideal for bushfire‑prone and building code‑driven residential projects – super lightweight, but very solid external walling system.
- Non‑combustible AAC fire rated material
- AAC is a mineral‑based, non‑combustible masonry product
- Does not burn, drip or release toxic smoke or flaming droplets
High fire resistance levels (FRL)
Fire-rated MaxiWall AAC wall systems carry certified fire resistance levels of at least -/120/120 for the 50mm panel and -/180/180 for the 75mm panel (assessed by IGNIS Labs to AS 1530.4; CodeMark Certificates CM40353 and CM40354), with documented party wall systems meeting the NCC 60/60/60 requirement – making them suitable for external walls, party walls and fire walls in low-rise residential projects. Because AAC is non-combustible, MaxiWall external systems also suit bushfire-prone sites, including BAL-FZ (Flame Zone) system options.
- Certified FRLs of -/120/120 (50mm panel) and -/180/180 (75mm panel), with party wall systems meeting NCC 60/60/60
- Excellent bushfire performance (BAL compliance)
- Complies with Bushfire Attack Levels including BAL‑FZ (Flame Zone)
Low thermal conductivity slows heat transfer
The cellular structure of Maxiwall AAC, with millions of air pockets, provides low thermal conductivity, so the fire exposed face heats up while the protected side stays cooler for longer, maintaining structural integrity.

Frequently Asked Questions
What fire rating do MaxiWall AAC panels achieve?
Independent testing assessed by IGNIS Labs to AS 1530.4 certifies a fire resistance level of at least -/120/120 for the 50mm MaxiWall panel and at least -/180/180 for the 75mm panel (CodeMark Certificates CM40353 and CM40354). Documented party wall systems meet the NCC 60/60/60 requirement. The rating achieved depends on the full system build-up, so always specify from the relevant system manual.
Are MaxiWall panels suitable for bushfire (BAL) zones?
Yes. AAC is non-combustible, and MaxiWall external systems suit bushfire-prone sites including BAL-FZ (Flame Zone) options. Confirm the specific system build-up for your BAL rating against the installation guide or with our team.
Are fire-rated MaxiWall walls load-bearing?
It depends on the system. The certified 50mm external wall system uses a load-bearing panel (510 kg/m3 nominal dry density) fixed vertically to timber or steel framing, while the documented high-rise internal wall systems are non-load-bearing partitions. Specify from the relevant system manual.
