Even minor material missteps can lead to massive project disruption. Most failures don’t come from lack of product knowledge—but from unchallenged assumptions, missed reviews, or failure to account for real-world variables.
The Failure: Inappropriate Interlayer Used in Laminated Railing System
A distributor selected a standard PVB interlayer for laminated glass railings in an open-air commercial building. While the product met initial specs, exposure to prolonged moisture caused delamination, resulting in visible clouding and client complaints.
The railing system had to be dismantled across all five levels.
Root Issues
No consideration of moisture exposure in the selection process.
Interlayer choice was made based on price and availability, not durability profile.
Field usage conditions were not reviewed with the engineering team.
Financial and Brand Impacts
Over $200,000 in replacement and labor costs.
Building operator filed warranty claim and issued public feedback.
Multiple future projects from the same contractor were lost.
Process Corrections
Require environmental exposure checklists for all outdoor glass applications.
Limit substitutions on critical components without written engineering signoff.
Offer premium-grade alternatives with pros/cons clearly presented to clients.
Material selection isn’t just technical—it’s risk management. Distributors who ask deeper questions protect the job, the client, and the bottom line.
