Abstract：In view of the advantages and shortages for the existing thermal insulation materials in the market,a new type composite thermal insulation material which can achieve synergies in different thermal insulation materials is designed. The com-posite material of double-board thermal insulation material is assembled using rigid polyurethane foam board laminated with vacu-um insulation panel by binding mortar,and the combination of two kind thermal insulation materials is designed according to the derivation formula. Thermal conductivity coefficient of the composite thermal insulation material was tested in the laboratory. The test results can meet the requirements of engineering regarding the heat transfer coefficient and the thickness of the insulation lay-er. In this paper,the reason for the difference between the measured thermal conductivity coefficient and the design value are also discussed. The main reason is the reduction of thermal insulation effect caused by thermal bridge, which leads to the difference of the numerical value between the two.
