Research Progress of Composite Thermal Insulation Wall in Hot Summer and Cold Winter Zone of China

Abstract

External wall has great impact on building energy conservation. Developing composite wall is direct way to improve the situation of building consumption. In this study, the importance of building energy conservation was analyzed. Several types of composite thermal insulation wall were listed and their advantages and disadvantages were discussed. Self-insulation composite wall has unique superiority, especially in hot summer and cold winter zone. Meanwhile, the application prospect of composite wall with combinations of insulation coating of high reflectivity and silt sintered porous brick was introduced. Finally, combining regional character, some suggestions were proposed on the further development of China’s composite wall in hot summer and cold winter zone.
