Thermal Characterization of Recycled Materials for Building Insulation

The building sector is known to have a significant environmental impact, considering that it the largest contributor global greenhouse gas emissions of around 36% and also responsible for about 40% energy consumption. Of this, 50% takes place during operational phase, while 10–20% consumed in materials manufacturing, transport construction, maintenance, demolition. Increasing necessity reducing impact buildings has led enhancing not only thermal performances materials, but sustainability their production chains waste prevention. As consequence, novel thermo-insulating or products been developed by using both locally produced natural waste/recycled are able provide good having lower impact. In this context, aim work detailed analysis characterization recycled insulation. To end, behavior different representing industrial residual wastes collected Sardinian zero-km available raw was investigated, namely: (1) plasters with materials; (2) fibers; (3) insulation fibers. Results indicate investigated were improve comfort new existing buildings. particular, mortars fibers showed, respectively, values conductivity (at 20 °C) than 0.475 0.272 W/(m?K), always 0.162 W/(m?K) compounds (0.107 W/(m?K)). Further developments underway analyze mechanical properties these materials.
