In this work, the thermal potentialities of insulation panels made of cork have been explored by means of a numerical approach based on experimental data. A comparative analysis between the panel in unaltered state, and then covered with an innovative shield coating (COIB 250®) was carried out. In addition, a defect simulating an inner detachment of the panel was fabricated to understand its behaviour during a daily solar thermal load. The site was selected ad hoc to avoid any shadow cast effect on the panel itself and any conduction phenomenon from the surrounding area.

The aim of this experimental investigation is to assess the response to low velocity impacts of green sandwich
structures made of agglomerated cork encapsulated between two thin flax/epoxy face sheets. Three different
cork densities were considered to assess their role on the response to impulsive loading, both in low and high
strain rate conditions by Split Hopkinson Pressure Bar (from 90 to 238 1/s). The performance of these structures
has been compared to that obtained with similar specimens using a traditional synthetic foam core. Despite the
