Title:
Abstract:	Der Artikel stellt u.a. umfangreiche Berechnungen zur Wärmebrückenproblematik am VIP-Rand dar, die im Rahmen eines Forschungsprojektes “Energetische und wirtschaftliche Optimierung von VIP-Paneelen“ durchgeführt wurden. Zusätzlich wird eine Vielzahl von Messwerten der Wärmeleitfähigkeit von VIP ausgewertet, die aus eigenen Untersuchungen und anderen Forschungsprojekten stammen, um die unterschiedlichen Temperaturlagerungen und Klimawechselprüfungen hinsichtlich des Anstiegs der Wärmeleitfähigkeit der Paneele zu vergleichen. Aus den Ergebnissen werden Hinweise für die Produktion der Paneele abgeleitet und die Rahmenbedingungen für den Einsatz günstigerer Stützkerne aus Mineralfasern untersucht. Investigations into Ageing and Thermal Bridging in Vacuum Insulation Panels (VIP) for Construction Applications. The article describes inter alia extensive calculations for thermal bridging problems at the VIP edge, which were conducted as part of a research project entitled “Optimisation of the energy-related and commercial aspects of VIP panels“. In addition, a number of measurements of the thermal conductivity of VIP are evaluated. These measurements came from our own studies and other research projects, and the purpose of the evaluation is to compare the effects of different storage temperatures and climate-change tests on the increase in the thermal conductivity of the panels. Guidelines for the production of panels are derived from the results, and the conditions for the use of more economical mineral-fibre support cores are investigated.
