Based on the energy saving design standards in hot summer and cold winter zone like Anhui province, a new type of sandwich insulation composite wall panel is researched, Influence on thermal performances of new sandwich insulation composite wall panel,due to in different thermal insulation material, different content of the oblique connection rebar, different thermal insulation layer thickness and different internal and external wall thickness, are analyzed. The results show that, in not take extra insulation measures, this kind of sandwich insulation composite wall panel thermal performance can meet the hot summer and cold winter area energy-saving design standard requirements. Research results and practical engineering contact tightly, It has a comparatively high practical value.
