Abstract: The aim of this study is to explore the effect of stud on the characteristics of thermal insulation and decoration composite system. Prior research conducted has primarily focused on the insulation material performance aside from the composite system. The theoretical calculation and field measurement method are adopted in this paper to compare the insulation performance for different building envelope systems. By considering the thermal transfer coefficient as the performance indicator, thermal bridge and air cavities of integrated insulation composite system as impact factors are investigated. Firstly, the high insulation performance of the composite system is determined via comparing other systems. Secondly, the thermal bridge issue of the composite system led by stud is subsequently investigated followed by the air cavity influenced element being studied via field measurement, which is caused by stud condition. Final results indicate that the thermal insulation and decoration composite system can achieve a substantial insulation performance. In this case, the corresponding optimal size of studs and air cavity is achieved. Further, scattered layout of air cavities could apparently improve the entire thermal system’s insulated performance. All these studied conclusions can contribute designers to implement this system more accurately.

Final results can contribute to the future building envelope design in terms of the insulation ability and close the gaps for investigations into the field of composite insulation systems. Additionally; it can also be conducive for architects to employ the optimal construction with regard to details such as stud distribution and air cavity layout for this composite system so as to achieve the optimal insulation and decorated performance.
