The lack of thermal comfort is related to the sensation of cold and heat perceived inside dwellings. The problem’s main cause is self – construction, where non – insulating and low – quality materials are used, which weaken the thermal performance of the residential envelope. For this reason, during the frost season, the low temperatures increase the vulnerability of regions in the center–south zone of the country, such as Apurimac, Cusco, Puno, among others. Consequently, over one million residents are exposed to a high rate of personal injuries, emergencies, and severe illnesses. The problem is delimited in the province of Abancay since rural houses cannot reduce the impact of frosts. Therefore, this investigation proposes the design of an insulating mortar for exterior wall covering, replacing the fine aggregate with wheat straw and cork at 5%, 10%, and 15%. The improvement of the mortar’s thermal and mechanical properties is demonstrated through laboratory tests and housing prototypes. The thermal conductivity of the insulating mortar samples were 0.183W/mK, 0.166W/mK, and 0.132W/mK, which are less than the conventional mortar. Furthermore, the compressive strength at 28 days were 92.5 kg/cm2, 60.8 kg/cm2, and 26.1 kg/cm2, overcoming the minimum resistance of the ASTM-C270 standard. Finally, the indoor temperature of housing prototypes increased by 4.5°C in cold weather. In this way, great thermal reinforcement is granted, using materials from the area, economically accessible and eco-friendly.
