An investigation of usability of expanded perlite in heat insulation technologies

The growth of global human population has increased the world energy demand and made it necessary to evaluate effectively and efficiently usage of energy sources. According to the international energy research projections' data, world's energy reserves will be ended in the next 100 years. The fact that the large portion of energy consumption is used in buildings for heating. Therefore, saving that energy is so important in buildings and the need for thermal insulation materials has increased day by day. The investigation of new technologies and new materials has already been continued for thermal insulation. In this study, using of the perlite, whose 74% of the world reserves are in Turkey, in building sector directly as an insulation material and/or reinforcing material in other building materials has been investigated.
