TRC sandwich solution for energy retrofitting

Concerning energy improvement of existing façades, a favourable system involves prefabricated multilayer panels, made internal insulation core and outer textile reinforced concrete layers. It is convincing alternative to external thermal composite systems (ETICS) ventilated it meets all the requirements for façade systems. The main advantage possibility toapply panel using crane, without any scaffolding. paper considers two solutions: former uses expanded polystyrene (EPS) as insulating material; latter substitutes EPS with an innovative green material inorganic diatomite. aims at comparing solutions in terms mechanical properties components behaviour sandwich lab-scale level. Numerical models, previously calibrated, will be instrumental discussion.
