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

The key to integrated construction of GRC curtain walls and insulation systems lies in solving issues such as insulation fixing, thermal bridge treatment, and construction sequencing. Through system innovation, Qinglong GRC achieves a perfect combination of insulation and decoration.

In a commercial complex project in Shenyang, Qinglong GRC adopted a built-in insulation board system: 100mm thick rock wool boards were fixed with dedicated connectors, with a thermal conductivity of ≤0.040W/(m·K). The system's heat transfer coefficient is ≤0.45W/(m²·K), meeting the 75% energy-saving requirement. After three winters, the interior surfaces of the project showed no condensation, demonstrating significant insulation performance.

Key Points of Insulation Fixing Technology

Stainless steel thermal-break anchor bolts are used with an anchoring depth of ≥50mm; anchor bolt spacing is ≤300mm, arranged in a staggered pattern; insulation boards are tightly joined and laid with staggered joints. Reliable fixing is the foundation of system safety.

Key Techniques for Thermal Bridge Treatment

Connectors use nylon 66 thermal insulation gaskets with a thermal conductivity of ≤0.3W/(m·K); insulation strips are installed at board joints, continuous and complete; penetration points are sealed with foam sealant. Thorough thermal bridge treatment ensures energy-saving performance.

Key Points of Construction Sequence Coordination

Install the insulation layer first, then install the GRC panels; construct in layers with fire stopping at each level; carry out sealing work promptly to prevent rainwater intrusion. Proper sequencing avoids potential quality issues.

System Performance Assurance Measures

Conduct wind pressure resistance testing (≥5kPa), thermal performance testing, and fire resistance testing (≥1h); set up inspection openings for convenient later maintenance; perform regular infrared thermal imaging inspections. System testing ensures performance.

Integrated construction requires systematic design. It is recommended to select an experienced manufacturer and carry out necessary testing. Qinglong GRC provides comprehensive integrated solutions to ensure system performance.
