Development of a New Type of Precast Concrete Inorganic Insulation Sandwich Wall Panel and Study on Its Thermal Performance

A new type of precast concrete inorganic insulation sandwich panel consisted of internal and external reinforcement concrete layers,insulating layers and FRP connectors is introduced.The panel has the advantages of energy saving,fire resistance and durability,and can realize the same life-span between the insulation and main structure.The thermal performance test of the kind of composite panel is carried out.The results show that heat transfer coefficient of the wall is 0.738W/(m2.k),which can meet the requirements of JGJ 134—2001 《Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Zone》.
