If the broken pane is tempered glass (small square pebbles when shattered), the entire sheet can implode at any moment. Cover it with heavy cardboard and tape until repair. Have a broken window now? Call a local glass shop and ask for a “sealed unit replacement.” They’ll walk you through measurements over the phone.
You notice a crack, a hole, or a fogged-up interior between your window panes. Your first thought might be, “Do I need to replace the whole window?”
The good news: You can often repair just the broken pane or the insulated glass unit (IGU) itself. But you need to act quickly—not just for security, but to prevent further damage.
