Abstract：
By using sandwich insulation technology, the structural layer, insulating layer and protective layer of panels were completely prefabricated in the factory, and forming the fabricated of prefabricated sandwich insulation composite panels. This article describing the production process of composite exterior wall panels and proposing the key control parameters of production technology. Through the demonstration projects to evaluate the overall effects of the fabricated construction, the result showed that sandwich insulation composite panels can achieve the goal of same lifespan between thermal insulation layer and structural layer. The prefabrication rate of the composite panel construction increased by 20%, and prefabricated composite panels structure applied in cold regions is completely feasible.
