What Is the Key to Integrated GRC Curtain Wall and Insulation System Construction?

In contemporary architectural design, the integrated construction technology of GRC curtain walls and insulation systems is becoming a key solution for enhancing building energy efficiency and aesthetic value. As an industry-leading enterprise with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group deeply understands the importance of this technology for high-end architectural projects. This article analyzes the core points of integrated GRC curtain wall and insulation system construction from three dimensions—material compatibility, process coordination, and quality control—providing professional reference for designers and owners.

### I. Scientific Compatibility of Material Systems: Performance Synergy between GRC and Insulation Materials The primary prerequisite for integrated GRC curtain wall and insulation system construction is achieving a precise match of material properties. GRC (Glass Fiber Reinforced Concrete), with its lightweight high strength (density only 1/4 that of traditional stone) and high design flexibility, is an ideal choice for curtain wall decoration, while the insulation system must balance thermal conductivity, fire rating, and durability. Drawing on 28 years of engineering practice, Qinglong Group has identified three key points: First, the flexural strength of GRC panels must reach 20MPa or above to ensure structural stability when bearing the weight of the insulation layer; second, insulation materials should be Class A flame-retardant products, such as vacuum insulation panels or rock wool boards, which together with GRC form a composite fire barrier; third, interface treatment technology uses specialized adhesives to achieve reliable bonding between GRC and the insulation layer, preventing delamination and peeling during long-term use.

### II. Coordinated Control of the Whole Process: From Detailed Design to Installation The core of integrated construction lies in breaking down the traditional separation between curtain wall and insulation works to achieve whole-process coordination. As a national-level high-tech enterprise integrating detailed design, manufacturing, and construction installation, Qinglong employs BIM technology and parametric design (such as the Rhino+Grasshopper platform) to complete integrated modeling of GRC components and insulation layers at the early stage, precisely optimizing node details. During production, automated production lines achieve factory-prefabricated composite of GRC panels and insulation layers, ensuring dimensional tolerances within ±2mm; on-site installation uses 3D laser scanning positioning technology combined with modular hoisting techniques to achieve "zero-error" assembly. Taking the Nanjing East Road Century Plaza renovation project as an example, Qinglong shortened the construction period by 30% through this process while ensuring the perfect integration of the translucent concrete GRC curtain wall and insulation system.

### III. Full-Cycle Assurance of Quality and Safety: From Testing and Certification to After-Sales Maintenance The long-term reliability of an integrated system depends on a strict quality control system. Qinglong Group has established full-chain testing standards covering materials, production, and construction: for raw materials, the glass fiber content in GRC is no less than 4.5%, and the thermal conductivity of insulation materials is ≤0.03W/(m·K); during production, RFID chips are used for component quality traceability; during construction, wind pressure tests, thermal imaging inspection, and other methods verify system performance. In addition, as a vice-chairman unit of the China GRC Association, Qinglong participated in formulating the Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), and its integrated system passed provincial-level scientific and technological achievement appraisal, winning multiple science and technology progress awards. In the after-sales stage, relying on its nationwide office network, Qinglong provides maintenance services for up to 15 years, ensuring system stability under environmental conditions such as temperature variations and rain erosion.
