   Abstract：The article analyses the construction error values of unitized curtain wall horizontal joint by comparing different technical codes. By concerning construction temperature，calculating method of unitized curtain wall horizontal joint and amount of overlap which temperature deformation influences are discussed. In addition，the portion which structure deformation holds in unitized curtain wall horizontal joint and amount of overlap is illustrated through serial cases. Finally，issues that should be noticed when designing unitized curtain wall are given，and the importance of the combination of technical measures and construction scheme in design is put forward.
