Double pane windows are often the preferred choice of homeowners because they are energy efficient, improve noise reduction and make the home more comfortable overall. That being said, when one pane of these windows is damaged, homeowners often ask if they can simply replace a single pane of glass in a double pane window. Keep reading below to see if that type of window repair would be feasible.
Double pane windows are exactly how they sound: two single panes glazed to the window’s sash, typically with air separating the two panes. The most energy efficient double pane windows have argon gas pumped into the empty space because it acts an insulator. The biggest benefit of double pane windows is their ability to insulate a building against the elements. That, in turn, lowers heating and cooling bills, usually saving homeowners hundreds of dollars every year.
What to do when one pane is damaged in a double pane window
Sometimes, the exterior window pane can become scratched or cracked from outside elements, such as falling tree branches and extreme weather. However, because each pane is glazed to the window sash, it’s not a simple process to just replace a single pane. In fact, the possibility of causing further damage to the window is very high when trying to replace one pane of a double pane window.
The damaged pane itself could shatter, sending window shards onto the unfortunate person trying to make the repair. In addition, any specialized gas in place to improve insulation would escape, making your double pane window much less effective. Finally, the process of loosening the window sash to replace a single pane often results in a weaker seal, again lowering the thermal effectiveness of your window.
