Thermal performance of sandwich insulation system according to the type of form-tie
Highly insulated envelope or external insulation systems are being applied in recent energy saving buildings to reduce the heat loss through envelope.Internal insulation systems are applied to most apartments in Korea because they are inexpensive and convenient to construct.However, the internal insulation systems have poor performance due to the heat bridges through structures such as slabs.The external insulation systems have better thermal performance because the heat bridges through the structure are rarely formed.But it has problems regarding the extemal insulator separation due to strong winds, spread of fire due to insulator combustion in case of fire, formation of heat bridges through the connectors between structure and extemal insulation.To supplement the weaknesses of the internal and the external insulation systems, a sandwich insulation system has been suggested.In this study, the thermal performance of sandwich insulation system for apartment buildings was evaluated according to two type of the form-tie material.
