Heat storage materials on the basis of liquid paraffins and their narrow fractions with the set temperature of phase transition and the increased heat capacity for enclosing the structures of buildings are received. A method of formulating compositions heat-storage materials with melting temperatures below 250C and increased heat capacity from a mixture of narrow fractions of commodity paraffins is proposed. The technique of obtaining heat-storage materials on the basis of commodity paraffin by mixing components, in obtaining HSM with specified thermal characteristics, the research of component composition, physico-chemical and thermophysical properties, in the research of their operational properties. The technical conditions for the obtained heat- storage materials on the basis of commodity paraffins are developed and the possibility of their application in the enclosing structures of buildings is substantiated. The developed heat-storage material with the set operational properties provides energy saving due to increase of heat capacity and intensity of heat exchange of enclosing designs of buildings.
