Thermal insulation performance of a multi-layered waterproofing membrane system with sandwich type of polyethylene foam and aluminum film was evaluated by using small specimen in the indoor environmental test chamber, and was compared with the effect of insulation sheet layers, the heat load on concrete substrate or the correlation with outdoor test results. The test specimens were 6 types; only concrete, single urethane system and some multi-layered systems with thermal insulation sheet. The indoor test was carried out with temperature cycles of 20°C to 80°C and 20°C to -20°C. The temperature of specimens were calculated by using the simplified calculation equation about the effect of season and specimen size, and the thermal insulation behavior between measurement value and the predicted value of had a good correlation. Also, the waterproofing system with multi-layered insulation sheets had a high insulation performance than that of existing systems, and can contribute to the reduction of heat load on concrete substrate and the saving energy.
