What testing and quality control processes are required before installing a curtain wall system?

Robust testing and quality control prior to installing a metal curtain wall system mitigate risk and ensure regulatory compliance. Key pre-installation steps include full-scale mock-ups tested for water penetration, air infiltration, structural wind loading, and thermal movement; these mock-ups validate the integrated performance of glazing, seals, anchors and drainage under simulated conditions reflective of the Middle East or Central Asian climates. Laboratory testing of individual components—glass impact and strength tests, gasket aging, sealant movement capability, and finish adhesion—provides baseline data. Factory Quality Control (FQC) ensures extrusion tolerances, assembly protocols, and glazing procedures meet specifications; factory acceptance tests (FAT) including dimensional checks and seal verification precede shipment. Anchor and bracket pull-out testing on representative substrates at the job site confirms the suitability of connection strategies for local concrete or steel conditions. Third-party inspection by accredited façade engineers or certifying bodies strengthens EEAT credentials and speeds approvals with authorities such as Dubai Civil Defence or regional code bodies. Additionally, maintaining traceability of materials (mill certificates, coating batch reports) and providing detailed installation manuals and training for site teams are essential. A documented QC plan, combined with manufacturer supervision during critical installation stages, ensures the delivered metal curtain wall system performs as tested and designed.
