Thermal and Acoustic Characterization of Innovative and Unconventional Panels Made of Reused Materials

Europe calls for a transition to the circular economy model based on recycling, reuse, proper design of products, and repair. Recycling requires energy chemical products waste processing; contrary, reusing reduces impact transportation expands life materials that cannot be recycled. This article highlights characteristics selected end-of-life materials; it aims raise awareness among manufacturers consider products’ conscious facilitate their reuse in different sectors. Panels 7 cm thick, realized by assembling cardboard packaging, egg boxes, bulk polyester, felt, have been experimentally tested understand whether they can installed indoors improve thermal acoustic comfort. The panels’ equivalent conductivity ?eq measured through guarded hot plate method is 0.071 W/mK. Acoustic tests performed sound transmission room reverberation room. weighted reduction index Rw 19 dB, absorption coefficient ?w 0.30, noise NRC 0.64. properties compared those commercial materials, results show panels interesting from points view. They could employed building sector disadvantaged contexts where low-income people afford insulating materials. Although other factors, such as fire resistance, need evaluated, these proposed approach feasible.
