conclusion vip1
Conclusion: VIP1

+ Easy to handle  structuralglazing

  • High performance for adjustablefixingsystem
  • Avoidventilationbehindpanels (mineralfibers)
  • Reasons for cracks in ceramicplates unknown,

probably to thin (3mm)

  • Surface to sensitive for impacts (Vandalism)
  • Ventilated VIPs: to many
  • Thermal bridges: extraenergyloss 43%

 not yet recommended

to be furtherdeveloped
