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 TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18
Conclusion: VIP2 + commonETICS-technique + VIPprotected + Ventilated VIPs: veryfew: < 1% + Thermalbridges: extraenergyloss 10% recommended TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18
