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

The key to integrated construction of GRC curtain walls and thermal insulation systems lies in four core elements: interface compatibility, construction coordination, secure fixing of the insulation layer, and reliable waterproof sealing. Through integrated design and standardized construction, Qinglong achieves seamless integration of the two, with a 100% insulation compliance rate across multiple projects, energy efficiency improved by 15-20%, and no hidden risks of detachment or leakage.

I. Interface Compatibility: Ensuring Structural and Performance Coordination

Interface compatibility is the foundation of integrated construction, preventing the two from affecting each other. Material compatibility: GRC panels and insulation materials (such as rock wool and extruded boards) must be chemically compatible, with no corrosion or aging reactions; Qinglong selects non-combustible rock wool insulation boards whose compatibility with GRC has been verified by authoritative testing. Mechanical matching: the insulation layer must have a compressive strength ≥0.4MPa and a tensile strength ≥0.15MPa to avoid deformation during construction or use; Qinglong's insulation material strength indicators far exceed the standards, with a 95% match to GRC mechanical performance. Thickness adaptation: the insulation layer thickness is determined by energy-saving requirements (20-50mm) and must be compatible with the installation space for GRC hangers; Qinglong's integrated design reserves hanger installation slots without occupying insulation layer space.

II. Construction Coordination: Ensuring Efficiency and Quality

Coordinated construction sequencing and workflows avoid rework and conflicts. Construction sequence: the sequence of "fixing the insulation layer first, then installing GRC panels" is adopted; after the insulation layer is fixed, moisture-proofing treatment is applied before the GRC panels are installed; Qinglong's construction sequence has been optimized through BIM simulation with no process conflicts. Synchronized detailed design: GRC panel breakdown and insulation layer layout are designed synchronously, ensuring that insulation layer joints are staggered from GRC joints to avoid thermal bridging; in Qinglong's detailed design, the layout deviation between the two is ≤50mm. Unified quality control: insulation layer laying and GRC installation are coordinated by the same team to avoid unclear division of responsibility; Qinglong implements "one-stop" construction management with a quality issue response time of ≤24 hours.

III. Insulation Layer Fixing and Waterproof Sealing: Ensuring Long-Term Stability

Secure fixing and waterproof sealing are the core guarantees of integrated construction. Insulation layer fixing: a dual method of mechanical fixing (plastic anchors) plus adhesive fixing is adopted, with anchor spacing ≤500mm and at least 4 anchors per square meter; Qinglong's anchors have a tensile load-bearing capacity ≥0.3kN, ensuring firm fixing without loosening. Waterproof sealing: insulation layer joints are sealed with sealant, and gaps between GRC panels and the insulation layer are filled with waterproof insulating mortar; Qinglong's sealant has excellent compatibility with the insulation layer, and the waterproof mortar has a compressive strength ≥30MPa. Node treatment: the insulation layer at nodes such as door and window openings and corners must be extended to provide coverage and avoid localized heat leakage; Qinglong extends the insulation layer at nodes by ≥100mm, with sealant applied continuously without breakpoints.
