07 Assessment
Advantages
- Maximum natural daylighting and visual transparency
- Excellent compressive strength (>1000 MPa) and stiffness (70 GPa)
- Non-combustible material classification under NCC
- Wide range of performance coatings (low-E, solar control, self-cleaning)
- IGU configurations achieve good thermal performance (U-value 1.1-2.8 W/m2K)
- Laminated glass provides acoustic performance up to STC 45+
- Durable and low-maintenance surface (50-100+ year lifespan)
- Design flexibility with clear, tinted, patterned, printed, and smart glass options
Constraints
- High embodied carbon from energy-intensive manufacturing (~1500 degC melting)
- Poor thermal performance as single glazing requiring IGU systems for compliance
- Brittle failure mode - toughened glass fragments, laminated retains but cracks
- High installed cost for structural glazing systems ($300-750+/m2)
- Solar heat gain requires careful management (coatings, shading, orientation)
- Heavy for large panels - 2.5 kg/m2 per mm thickness
- Fire-rated glazing significantly more expensive than standard
- Aluminium framing contributes substantial additional embodied carbon
08 Applications
A1 Commercial curtain wall facades Primary building envelope system for office towers, retail centres, and institutional buildings providing transparency, daylighting, and weather protection
A2 Structural glazing systems Point-fixed, spider fitting, and structural silicone glazing for frameless or minimally-framed glass facades with maximum transparency
A3 High-performance windows Double and triple-glazed IGU systems for residential and commercial windows meeting NCC energy efficiency requirements
A4 Glass balustrades and barriers Toughened and laminated safety glass panels for balconies, stairs, pool fences, and barrier applications per AS 1288
A5 Fire-rated glazing Specialist fire-rated glass assemblies (Pyranova, Pyran) providing FRL -/120/120 for commercial building fire separation requirements under NCC 2022
