07 Assessment
Advantages
- Instant privacy control (<0.1 second switching)
- 99% UV blocking protection
- Acoustic insulation improvement (20% noise reduction)
- Projection screen capability when opaque
- No moving parts or maintenance of blinds/curtains
- Compliant with AS/NZS 2208 safety glazing
- Energy savings through reduced HVAC loads
- Hygienic surface (no dust collection)
- Dimmable options available (0-100% transparency)
- Multiple control options (switch, remote, app, automation)
Constraints
- High initial cost (AUD $1,100-1,500/m² installed)
- Requires constant power for transparency (5W/m²)
- Not completely opaque (translucent when off)
- Vulnerable to moisture ingress at edges
- Limited fire resistance rating
- Potential yellowing after 10-15 years
- Electrical installation required
- Cannot achieve complete blackout
- Size limitations (max 2m x 6m single panel)
- Higher embodied carbon than standard glass
