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

Integrated construction of GRC curtain walls and insulation systems is the key to unifying building energy efficiency and decoration. In projects such as the Shenzhen Pingshan High-tech Zone Comprehensive Service Center and the Yangshengtang Pharmaceutical Hangzhou Industrial Park, Qinglong Group achieved efficient integration of GRC decoration and insulation functions through structural innovation, process optimization, and material matching.

Structural design is the foundation of integrated construction. Qinglong Group adopts a three-in-one structural system of GRC decorative panels, insulation layers, and structural layers. In the Shenzhen project, GRC panels were bonded to the insulation layer with staggered joints through connectors, preventing thermal bridging. The selection of insulation materials takes fire rating and durability into account, typically using rock wool or graphite polystyrene boards with a thermal conductivity of ≤0.040W/(m·K).

Connection system design is a critical link. Qinglong Group developed dedicated connectors that ensure structural safety while blocking heat conduction. The connectors are made of stainless steel and isolated from the main structure through thermal insulation gaskets. In the Wuhan Han Show Theater project, this connection system reduced the overall heat transfer coefficient of the curtain wall to 0.8W/(m²·K), far below the code requirements.

Sealing and waterproofing treatment requires holistic consideration. Qinglong Group installs continuous insulation layers at panel joints to prevent cold bridging. Pipes penetrating the panels are filled around with elastic insulation materials to ensure sealing integrity. During construction, protecting the insulation layer is particularly important to avoid damage that would compromise performance.

Quality control is the guarantee of successful integration. Qinglong Group verified structural performance and construction techniques through sample section testing. In material selection, the deformation compatibility between GRC panels and insulation materials must be matched to avoid cracking caused by temperature differential deformation. This systematic integrated solution achieves the dual goals of architectural aesthetics and energy efficiency.
