07 Assessment
Advantages
- Lowest thermal conductivity of translucent materials (0.016 W/m·K)
- Maintains light transmission (3-50%) with superior insulation
- Non-combustible silica core (dimensional stability to 650°C)
- Excellent acoustic damping properties
- Hydrophobic treatment prevents moisture damage
- UV blocking capability (<1% transmission)
- Museum-quality light diffusion
- 25+ year service life expectancy
- Lightweight compared to triple glazing
- No thermal bridging in properly designed systems
Constraints
- Premium cost (3-10x traditional glazing)
- Limited Australian suppliers and long lead times (12-16 weeks)
- No NATA-accredited test reports for Australian standards
- Requires Performance Solution for NCC compliance
- Fragile during handling and installation
- Limited BAL ratings without specific testing
- Potential for aerogel settling over time
- Repair difficulty if damaged
- Limited recycling infrastructure
- High embodied energy from manufacturing
