  • Vakuumisolationspaneele (VIP) aus pyrogener Kieselsäure und metallisierten Folien als vakuumdichter Umhüllung wurden untersucht. Der Gas- und Feuchteeintrag durch die Folienumhüllung in das Panel wurde in Abhängigkeit von Folientyp, Panelformat und Klimabedingung ermittelt. Weiterhin wurde der Einfluss der Feuchte auf den transienten und stationären Wärme- und Feuchtetransport bestimmt. Anhand der Ergebnisse lässt sich die Degradation der Dämmwirkung der untersuchten VIPs langfristig prognostizieren.
  • Vacuum insulation panels (IP) made of fumed silica as core material and metallized foils as vacuum tight envelope were examined. The permeation of gas and moisture through the foil envelope was determined, depending on foil type, panel format and climatic conditions. In addition, the influence of gas and moisture on the transient and stationary heat and moisture transfer was analyzed. The study makes it possible to estimate the long time degradation of the thermal conductivity of the examined VIPs
