Abstract
In this research we tried to improve the thermal insulation efficiency of polystyrene foam by adding some natural materials. The gebrile soil was selected for several reasons, including abundance and ease of processing before the addition - There are many previous researches for soil treatment -. We have found at ratio 20%(The proportion of the soil in the compound) the coefficient of conduction is low and then rises after this percentage As for the absorption of water it increases by increasing the soil, but at this ratio the absorption is within the permissible limit according to the specifications required for the insulation materials and also compressive strength increase with the increasing of the soil ratio because of increasing of mechanical links between the polycarbonate and polystyrene particles and composite-material’s density increasing in general.
