School Trophy Case Laminated Glass Delamination Inspection Checklist
Intent: research — a school trophy case laminated glass delamination inspection is a structured assessment of the interlayer bond condition in multi-ply laminated glass panels installed in enclosed display cases used to house school recognition collections. Laminated glass — constructed from two or more glass plies bonded by an interlayer of polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), or structural ionomer film — is the only common glass type that holds its fragments in place when broken, a safety characteristic that depends entirely on the integrity of the bond between the interlayer and each glass ply. When that bond fails in a condition called delamination, the laminate no longer behaves as a unified panel: edge bubbles form along the perimeter, haze spreads inward from the glass margins, moisture infiltrates the gap between plies, and the safety performance that distinguishes laminated glass from other glass types degrades silently behind an otherwise intact exterior surface. This guide explains what laminated glass delamination is, how to identify it through visual inspection, how to apply a repair-versus-replace framework to findings at each severity level, and how to use a structured checklist to document condition and assign correct follow-up actions for every laminated glass panel in a school’s trophy case inventory.
