Research on feature of thermal performance of integrated composite system

Abstract

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.
