07 Assessment
Advantages
- Non-combustible - meets all BAL categories
- 75% lighter than precast concrete
- 3x better thermal resistance than double brick
- 60% faster installation than traditional masonry
- Excellent acoustic performance (Rw 42-65 dB)
- Termite and vermin resistant
- 50+ year service life
- NCC deemed-to-satisfy material (AS 5146:2015)
- Can be cut with standard power tools
- No toxic emissions or VOCs
Constraints
- Moisture sensitive - requires vapour-permeable coating
- Limited impact resistance compared to traditional masonry
- Cannot be field modified once installed
- Requires skilled trades familiar with AAC techniques
- Single Australian manufacturer (CSR Hebel)
- Higher initial cost than some alternatives
- Brittle - requires careful handling
- Proprietary fixings required
- Fine silica dust during cutting requires PPE
- Additional insulation needed for NCC thermal compliance in some zones
