Based on the fracture pattern analysis, the failure is consistent with [Thermal Stress / Impact from Interior Object] , resulting in a fracture originating from the inner pane surface.
This report details the investigation regarding a window identified as "cracked from the inside." The objective is to determine the root cause of the fracture, distinguish between thermal stress and impact damage, and rule out potential structural defects or foul play. window cracked from inside
| Type of Crack | Likely Origin | Inside or Outside? | Impact Point? | | :--- | :--- | :--- | :--- | | | Near frame edge | Inside (if warm inside) | No | | Impact (ball/elbow) | Center of glass | Inside | Yes (crater) | | Frame Pressure | Edge to edge | Inside (pressure from frame) | No | | Nickel Sulfide | Random center point | Inside (tempered glass) | No (butterfly shape) | Based on the fracture pattern analysis, the failure
