07 Assessment
Advantages
- Maintains visibility during evacuation scenarios
- Prevents spread of fire, smoke and toxic gases
- Provides radiant heat protection up to 40kW/m²
- Available in large sheet sizes (up to 1.3m × 2.5m)
- Can achieve FRL ratings up to -/180/120
- Compatible with aluminium and steel framing systems
- No spontaneous breakage risk (no nickel sulphide inclusions)
- Impact safety ratings available (AS 2208 compliance)
- Clear appearance without amber tinting in modern products

Constraints
- Significantly higher cost than standard glazing (3-5× premium)
- Limited supplier base in Australian market
- Weight implications for structural design (especially laminated)
- Requires certified framing systems for rated assemblies
- Installation requires specialist contractors
- Cannot be cut or modified on site
- Long lead times for non-standard sizes (8-12 weeks)
- Limited thermal insulation in integrity-only products
- Replacement costs high if damaged
- Testing and certification requirements add project complexity
