Thermal performance evaluation on vacuum insulation panels in composite building envelope under large temperature variations

Thermal and sound insulation performance assessment of vacuum insulated composite insulation panels for building façades

“…extruded polystyrene foam, XPS) is that it can improve the thermal resistance of the building element without increasing the thickness owing to its low thermal conductivity of 0.004 Wm -1 K -1 (centre of panel) and 0.007 Wm -1 K -1 (including edge effects and ageing) (Wakili, Bundi & Binder, 2004). Use of vacuum insulation in buildings as a component in thermal composite insulation systems along with other insulation materials for achieving higher thermal resistance has been researched in number of studies (Hayez & Kragh, 2013;Mandilaras, Atsonios, Zannis, Founti, 2014;Voellinger, Bassi, Heitel, 2014;Kan and Hu 2017). Biswas et al, (2018) researched the use of vacuum insulation in composite insulation boards and found that vacuum insulation improved the thermal resistance by approximately two times compared to currently used insulation in buildings.…”
