07 Assessment
Advantages
- Provides privacy whilst allowing natural light transmission
- Permanent finish that won't wear or peel
- Can be toughened or laminated for safety compliance
- Acid-etched version resists fingerprints better than sandblasted
- Available in various opacity levels and patterns
- Suitable for all Australian climate zones
- Non-combustible material (BAL-FZ compliant when required thickness)
- 100% recyclable at end of life
Constraints
- Cannot be cut or modified after tempering
- Sandblasted finish shows fingerprints and requires more maintenance
- Higher cost than clear glass
- Reduced light transmission compared to clear glass
- Acid etching process involves hazardous chemicals
- Limited availability of acid etching facilities in Australia
- Fragile in annealed form - requires careful handling
