The core of this solution lies in accurately diagnosing insulation failure modes (such as aging, damage, thermal bridging, etc.) and implementing targeted repairs. We employ non-destructive or minimally invasive testing techniques to assess the integrity and thermal performance of the insulation layer. During repairs, we use high-performance elastic insulation materials, sealants, or prefabricated components to ensure seamless compatibility with the original system. The process emphasizes layered filling, airtight sealing, and restoration of the protective layer to thoroughly eliminate leakage and safety risks. The ultimate goal is to restore and optimize the insulation efficiency of the system, ensuring its long-term stable and economical operation.
