Silicone Structural Glazing

A structural glazing façade is designed as an aluminium-adapter-framework glued together with a special insulating glass unit using structural glazing silicones. This aluminium-glass-system is suspended into a conventional curtain wall construction. From the exterior side only glass and – depending on the system – weather sealant are visible.

Main features:

  • Joining technique appropriate for the material involved
  • No microstructural change of parts (e.g. as per welding)
  • Load transferring function
  • No local stress peaks by planar transfer of forces trough planar adhesive area
  • Ageing stability of silicone (adhesion, UV resistance, temp. resistance)
  • Safety at extreme mechanical loads (earth quakes, tropical cyclones, explosions, etc.)

A typical structural glazing junction consists of

  • Structural bonding providing a static effective connection
  • Insulating glass edge seal adapted on wind and dead loads and with density function
  • Weather seal

The structural silicones provide a high sheer and Young’s modulus for compensation or transferring

  • Dynamic loads (wind suction, wind pressure, traffic loads)
  • Static loads (dead and snow loads)
  • Differences in the thermal dilatations of involved materials such as glass and aluminium
