Development of Thermal Stress Free SMC for Prefabricated Bathroom -Thermo Floor-

The development of the thermal stress free waterproof pan for prefabricated bathroom, thermo floor was described in this paper. For development, the evaluation methods of cold sensitive index was discussed and defined as an index of discomfort when feet touched with surface of the pan. Ceramic balloon filler was used for reducing the thermal conductivity of the material. As a physiological evaluation, the change of temperature of feet bottom and blood pressure in touching thermo floor were confirmed to be lower than in touching existing pan. So, thermo floor is effective for decreasing the thermal stress
