Description

Triple glazed IGUs consist of three glass panes separated by hermetically sealed spacers creating two insulating cavities filled with air or argon gas. Available in 36mm, 40mm, 44mm and 52mm overall thicknesses, these units incorporate low-E coatings and warm-edge spacers to achieve exceptional thermal performance. Primarily specified for high-performance residential and commercial projects in cooler climates or where superior acoustic isolation is required.

Primary Sectors
[Residential][Commercial][Healthcare]
Typical Uses
  • Passive House and high-performance residential buildings
  • Commercial facades in cold climates (BCA zones 6-8)
  • Acoustic isolation for buildings near airports/highways
  • Heritage building retrofits requiring thermal upgrade
  • Hospital and laboratory clean rooms
  • Recording studios and broadcast facilities
  • Alpine resort accommodation
  • Energy-efficient office buildings
  • Residential apartments requiring acoustic privacy

Triple glazing technology emerged in Scandinavia during the 1970s energy crisis, with widespread adoption in northern Europe by the 1990s. Introduction to Australia began in the 2000s primarily for passive house projects. Manufacturing capabilities remain limited locally, with most high-performance units imported from Europe. Recent improvements in low-E coatings and warm-edge spacer technology have enhanced performance while reducing thickness requirements. Growing interest driven by increasing energy costs and stricter building codes, though market penetration remains under 5% compared to 80%+ in Scandinavian countries.
