How is glass facade performance evaluated during factory fabrication and on-site installation stages?

Performance evaluation begins in the factory: dimensional checks, glass edge inspections, spacer and sealant adhesion tests, and unitized panel pressure checks. Fabricators should produce a QA dossier with material certificates, heat-treatment records and batch numbers for sealants and coatings. Full-scale mockups undergo air and water infiltration tests per ASTM/EN standards and are used as the benchmark for site acceptance. On site, erect a verified mockup and perform witnessed tests—air/water infiltration, anchor torque verification and movement joint functionality—to confirm as-built performance. Maintain traceable inspection logs, photographic records and non-conformance reports. Post-installation leak testing and structural verification at critical spans should precede handover. For metal curtain wall suppliers, coordinating factory tests with site commissioning schedules and providing clear acceptance criteria reduces disputes and verifies durability under local conditions in the Gulf and Central Asia.
