Quality doesn’t fail in the field—it fails on the floor, long before the glass ever leaves the dock.
At a glazing job in Detroit, insulated units began showing premature seal failure just months after installation. The field team initially blamed storage conditions. But a deeper investigation revealed that one production shift had skipped the secondary seal inspection step after a recent software update changed the curing timer.
No alarms were triggered. No one noticed—until callbacks started piling up.
This is what QA/QC oversights really look like:
Unverified software patches
Skipped batch samples during peak runs
Misunderstood spec changes that don’t reach the floor
Glass distributors must move beyond visual checks and implement audit-ready QA processes. That includes:
Batch traceability for all IGUs, laminated units, and fritted panels
Temperature and humidity logging at each processing stage
Randomized lot testing and documentation for ASTM compliance
A single oversight in tempering, edge polishing, or sealant application can cost weeks of rework and six figures in contractor penalties. QA/QC is no longer just internal. Your customer feels every lapse.
