  1. TESTS OF VIPS IN SIMULATION, LABORATORY, AND PRACTICE Georg-Wilhelm Mainka Prof. em. Dr.-Ing. University of Rostock, Germany Heiko Winkler Dipl.-Ing. IAIB Wismar, Germany 9th International Vacuum Insulation Symposium The Royal Institution of GreatBritain London 2009-09-18 Revised Version 2009-09-30

  2. The KindergartenKita „Plappersnut“ in Wismar before Retrofitting: 2004 prefabConcrete Panels withceramic Skin after Retrofitting: 2009 East Gable Facade  VIP 1 North Facade West Gable f Facade  VIP 2 Inside Hall 2005: Award of the Journal „Bauphysik“ TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  3. Construction of VIP1 and VIP2 VIP1: Glass-Ceramic-Sandwich VIP2: ETICS withVIP-kernel TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  4. VIP1: Sandwich with 4 VIPs inside Sandwich Element with unsealedjoints Southern Half 2005 northern Half 2005 Sandwich Element Coatedonto the Anchor plate The Gap between oldfacade and Sandwich was filledwith Mineral Wool to avoidConvection Anchor plate TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  5. VIP1: Facade Plan , nearly ready Facade, and Thermography Southern Half 2005 TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  6. VIP1: Influence of Thermal Bridges (WB) Estern facadeca. 140 m² (2 gable wallssouth-north) Sandwich glass/ceramicwithVIP-kernel (ADCO company) WB 1 = WB 2 Φ‘= U*A + Σψ*l d = λ/(Φ‘*A) WB 3 -43% TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  9. VIP1: Long Term Behaviour Ventilation Southern Half northern Half 2005 underConstruction without Mineral Fibers 2009 TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  10. VIP1: Long Term Behaviour Cracks southern Half 2009 adhesive Figures added 2007 to hidecracks new cracksoccured CRACK With salty Rims at lower Element Border Detail CRACK CRACK CRACK IMPACT HOLE CRACK CRACK TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  11. VIP2: ETICS with VIP-Kernel northern Half 2005 underConstruction Coating Elements Fixing Joint between Elements Joints at Surface TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  12. VIP2: Facade Plan , readyFacade, andThermography southern Half 2005 ready Detail ventilated Element TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  13. VIP2: U-Value Long Time Monitoring: Temperatures [°C] and Heat Flux [W/m²] Measured U (k)-Value: U = 0.19 W/m²K TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  14. VIP2: Influence of Thermal Bridges Western facadeca. 140 m² (2 gable walls) ETICS withVIP-kernel (Stocompany) Φ‘= U*A + Σψ*l d = λ/(Φ‘*A) -10% TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  15. VIP2: Long Term Behaviour Ventilation 2005 Northern Half Southern Half 2009 TEST OF VIPS IN SIMULATION; LABORATORY, AND PRACTICE IVIS - THE ROYAL INSTITUTE OF GREAT BRITAIN - LONDON 2009-09-18

  16. 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

  17. 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
