Thermal insulation is a demand for all closed spaces when no heat exchange with the external environment is allowed to ensure a better thermal comfort (in living spaces) or for the use of the relevant building as industrial facilities, refrigeration rooms, etc.
The thermo-insulating materials are classified according to: raw materials, structure, hardness. The phonic or sound insulation is aimed at preventing noise penetrating the construction elements. Noise can be produced by the activities carried-out in the external or internal spaces or by the impact on construction materials
