Application of Thermal Insulation Mortar in Energy-Saving Retrofitting on the External Wall of an Existing Structure

This study focused on the application of thermal insulation mortar in energy-saving retrofitting of the external wall. It introduced the performance of the inorganic thermal insulation mortar and the insulation system structure of the external wall. The technology and requirements with inorganic thermal insulation mortar of the energy-saving retrofitting construction on external wall of existing structure was defined and carried out to pilot applications in the actual project. The results indicate that the inorganic thermal insulation mortar performed very well in both construction and operability in the energy-saving retrofitting construction on the external wall of the existing structure. After retrofitting, there was no inanition and no cracks on the external wall. The energy-saving effect was significant with the promoting rate of 14.1%.
