Quality assurance and quality control processes form the backbone of any serious glass distribution operation. But when these systems falter, the resulting errors can threaten structural integrity, public safety, and customer relationships. One overlooked dimension, one unchecked surface flaw, or one skipped inspection can spiral into massive liabilities.
Case Breakdown: Laminated Glass Delamination at a Hospital
A distributor delivered custom laminated glass units to a newly built hospital in British Columbia. Several months after installation, visible delamination appeared at the glass edges. Subsequent lab testing revealed that the PVB interlayer had been exposed to elevated humidity during pre-lamination staging—something that should have been caught during QA review.
Unfortunately, QA signoffs were missing for that batch due to temporary staffing shortages and a failed handoff between shifts.
The Damage
Nearly 100 units required replacement, including crane work for high-floor windows.
The client withheld partial payment and demanded financial restitution.
Internal audit revealed gaps in documentation and traceability for the failed units.
Root Causes
Incomplete QA documentation due to shift turnover issues.
No humidity control validation in pre-processing areas.
Lack of layered QC signoff before packaging.
Recommended Corrective Actions
Introduce multi-point QC verification with digital signoffs.
Implement environmental control logs in all staging zones.
Review and retrain teams on the importance of sequential QA adherence.
QA/QC isn’t just about compliance—it’s a reputation defense system. Glass distributors that treat quality as a documented, repeatable process build resilience into every panel they ship.
