Ultra-thin vacuum insulated glazing with exceptional thermal performance (U-value 0.4-0.7 W/m²·K) in 8.3mm or 10.3mm profiles, suitable for heritage retrofits and high-performance applications

Overview
Executive summary

Vacuum Insulated Glazing consists of two panes of glass (typically 4mm each for 8.3mm total) separated by a 0.3mm vacuum gap maintained by microscopic support pillars. The vacuum eliminates convective and conductive heat transfer, achieving thermal performance comparable to triple glazing in a profile similar to single glazing. Available in tempered safety glass variants compliant with AS2208 Grade A requirements.

Best when…
  • Exceptional thermal insulation (U-value 0.4-0.7 W/m²·K)
  • Ultra-thin profile (8.3-10.3mm) suitable for existing frames
  • Superior acoustic performance (Rw 36-41 dB)
  • Eliminates condensation risk (down to -70°C)
  • Long service life (25-50 years expected)
  • Lightweight (20 kg/m² for 8.3mm)
  • No gas fill degradation over time
  • Complies with AS1288 and AS2208 standards
  • Available in tempered safety glass (Grade A)
  • Suitable for all Australian climate zones
