Garage door windows crack, fog or yellow over time. Replacing just the glass — instead of the whole panel — is usually the economical repair. This guide explains the glass options and the measurements you need before ordering.
Glass Options
Clear, frosted, tinted and insulated double-glazed units are the main choices. For attached garages, insulated glass reduces heat loss; for security, laminated glass holds together when broken.
What to Measure
Measure the visible glass opening precisely, not the frame: width and height of the glazing pocket, plus the glass thickness. The insert type — snap-in, screw-fixed or integrated frame — determines the replacement method.
Panel vs Glass Replacement
If the panel skin or frame is damaged or the glass is bonded into the panel, replacing the whole panel is more reliable. Jusen can supply replacement panels matched to common garage door systems.

What glass thickness is normal?
