Abstract: The “Smart PI.QU.E.R.” project, supported by Lombardy Region (Italy), is aimed at developing a sandwich panel for the energy retrofitting of existing residential building. The panel is characterized by external textile reinforced concrete layers and by an eco-friendly inner insulation layer based on inorganic diatomite. The main feature of the panel is that it could be applied on an existing façade through four punctual connectors by means of a crane, without any scaffolder. Basing on the experience gained in the European project “EASEE”, the partners try to overcome some criticisms previously encountered in the EASEE panel, related to the use of expanded polystyrene as insulation material, to the cost of the anchoring system and to aesthetical issues related to the cracking of TRC layers. The main innovations of this panel concern: the development of a new insulation material, based on diatomite (natural source); the optimization of its shape; the optimization of textile reinforced concrete layers; the development of a new anchoring system. This paper is focused on the research developed at material level referring to both external layers and insulating core.
