How UHPC Exterior Walls Achieve Integrated Insulation: Energy-Saving Solutions and Technical Analysis

UHPC exterior walls achieve insulation integration through three core pathways: "built-in insulation layer, composite insulation panel, and insulation node optimization," enabling an exterior wall insulation coefficient of ≥0.8W/(㎡·K) that meets national energy-saving standards. Leveraging the collaborative design of insulation and UHPC, Qinglong provides efficient energy-saving solutions for projects such as the Yangshengtang Pharmaceutical Hangzhou Industrial Park and the Shenzhen Yirui Biotechnology Building.

I. Built-in Insulation Layer Integration: Fusion of Structure and Insulation

The built-in method achieves integration of insulation and structure. Process principle: during UHPC panel production, insulation materials (XPS board, rock wool) are embedded inside, and high-pressure vibration ensures tight bonding of the three; Qinglong's built-in insulation layer has a bonding strength of ≥0.8MPa with no risk of detachment. Insulation material selection: XPS board (thermal conductivity ≤0.028W/(m·K)) is suitable for mild climates, while rock wool (Class A1 fire rating) is suitable for projects with high-temperature and fire-protection requirements; Qinglong customizes the selection as needed. Advantages: the insulation layer is protected by UHPC, preventing aging; Qinglong's built-in insulated UHPC panels have a service life consistent with the main structure. Project case: the biopharmaceutical plant at Yangshengtang Pharmaceutical Hangzhou Industrial Park, with built-in XPS board UHPC exterior walls, achieves an insulation coefficient of 0.75W/(㎡·K), meeting the constant-temperature requirements of pharmaceutical plants.

II. Composite Insulation Panel Integration: Modular Assembly

The composite method flexibly adapts to different needs. Process principle: UHPC panel + insulation layer + back panel are composite-formed, prefabricated in the factory, and dry-hung installed on site; Qinglong's composite panels weigh ≤60kg/㎡ for convenient installation. Composite structure: panel (20-30mm UHPC) + insulation layer (50-100mm) + back panel (10mm cement fiberboard); Qinglong's composite panels achieve an insulation coefficient as low as 0.6W/(㎡·K). Sealing optimization: panel joints are filled with insulating sealant to avoid thermal bridging; Qinglong's sealant has a thermal conductivity of ≤0.03W/(m·K), leaving no insulation gaps. Application scenarios: commercial complexes and high-end residences. Qinglong's composite insulated UHPC exterior walls for the Shenzhen Yirui Biotechnology Building shortened the construction period by 30%.

III. Insulation Node Optimization and Qinglong's Technical Advantages

Detail optimization improves the overall insulation performance. Node design: insulation reinforcement layers are set at door/window openings and internal/external corners to prevent heat loss; Qinglong's BIM modeling optimizes nodes, reducing thermal bridging by 60%. Breather membrane installation: a breather membrane is laid on the inner side of composite panels for moisture resistance and breathability; Qinglong's breather membrane has a breathability of ≥1000g/(㎡·24h), protecting the insulation layer. Construction standards: continuity of the insulation layer without damage is ensured during installation; Qinglong's construction team is professionally trained, achieving a 100% insulation layer integrity rate. Technical advantages: participation in developing insulation integration-related standards and ownership of 8 patents related to composite insulated UHPC; Qinglong's insulation integration solution improves energy saving by 30% compared with traditional exterior walls. Project case: the Shenzhen Pingshan High-tech Zone Comprehensive Service Center, with composite insulated UHPC curtain walls achieving an insulation coefficient of 0.7W/(㎡·K), received Two-Star Green Building Evaluation certification.
