What you might be seeing

  • A visible crack in the outer or inner pane
  • A starburst from an impact point
  • A crack running from an edge (often thermal stress)

Common causes we find

Impact

Hail, falling branches or dropped tools.

Spontaneous breakage

Toughened glass can occasionally break without warning, which is why laminated inner panes are recommended overhead.
