Analysis of Key Technologies and Quality Control Points for Integrated Construction of GRC Curtain Wall and Insulation Systems

In contemporary architectural design, integrated construction technology combining GRC curtain walls with thermal insulation systems is becoming a key path to achieving both architectural aesthetics and energy-saving goals. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group has always upheld the mission of "creating beautiful buildings," providing high-end architectural projects with systematic solutions that combine artistic expression with engineering reliability through full-chain technology integration.

Technical Logic and Industry Value of Integrated GRC Curtain Wall Construction

GRC (Glass Fiber Reinforced Concrete), with its lightweight high-strength properties (weighing only 1/4 of traditional stone) and high design freedom (minimum curvature radius of 300mm), demonstrates unique advantages in landmark buildings such as grand theaters and convention centers. Integrated construction technology organically combines curtain wall decoration with thermal insulation functions, solving pain points of traditional construction such as "delamination between decorative and insulation layers" and "thermal bridging effects." The Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC) (JGJ/T423-2018), co-developed with the participation of Qinglong Group, provides an important industry basis for the standardized application of this technology.

Key Construction Techniques: From Material Innovation to Process Upgrading

Material formulation optimization is at the core of the technology. Qinglong's R&D team adjusts the glass fiber content (typically controlled at 4-5%) and the mix ratio of cement-based materials to keep the flexural strength of GRC components stable above 20MPa, while introducing hydrophobic additives to improve weather resistance. At the Nanning production base, automated spray-up molding processes achieve precision control of components; combined with BIM technology and 3D laser scanning, complex shapes such as double-curved surfaces and openwork reliefs are accurately realized.

Thermal insulation system integration reflects systems thinking. A composite structure of "GRC panel + insulation core material + backing board" is adopted, with thermal bridge interruption design blocking heat transfer. In the Century Plaza renovation project on Nanjing East Road, Qinglong innovatively applied translucent concrete integrated with GRC insulation technology, meeting the building's daylighting needs while improving energy-saving indicators by 30%. The project won the Silver Award of the First UHPC Building Engineering Innovation Award (AALBORG WHITE Cup).

Quality Control Essentials: Standardized Management Across the Entire Process

The detailed design stage requires parametric modeling, with emphasis on verifying joint construction and load calculations. In production, an RFID chip traceability system is introduced, with each component numbered to ensure product quality traceability. Installation adopts modular hoisting technology, achieving "zero-error" assembly through a 3D positioning system, with the anchoring system's safety factor increased by more than 20% in accordance with building curtain wall codes.

As a National High-Tech Enterprise and Vice Chairman Unit of the China GRC Association, Qinglong Group has established a full-chain quality control system covering detailed design, manufacturing, construction and installation, and after-sales maintenance. From incoming raw material inspection to a 5-year post-completion maintenance commitment, the Group strictly implements internal control indicators above industry standards, and has provided stable and reliable GRC system solutions for thousands of major projects at home and abroad.

Industry Trends and Qinglong's Practice

With the construction industry's growing demand for green, low-carbon, and modular construction, integrated GRC curtain wall and insulation system technology is developing toward lighter weight, higher strength, and greater intelligence. Relying on its provincial-level R&D center platform, Qinglong Group continues to advance UHPC and GRC composite technology research. In a commercial complex project in Shenzhen, UHPC/GRC combined curtain walls achieved a breakthrough of 15% reduction in building self-weight and 40% improvement in construction efficiency.

From domestic strategic cooperation projects with Poly and China Overseas Property, to overseas projects exported to Malaysia and Saudi Arabia, Qinglong Group has always upheld the values of "honesty, striving, trust, and collaboration," promoting the innovative application of GRC technology in the field of architectural decoration. Going forward, Qinglong will continue to focus on the development of UHPC/GRC/GRG/GRP materials, striving to become a world-class leading manufacturer of architectural decoration materials and contributing Chinese wisdom to global architectural aesthetics and sustainable development.
