Wind-driven debris can damage your windows’ glass panes, but there are other ways strong winds can damage your windows. Renewal by Andersen® of Alaska explains how strong winds can contribute to window seal failure and poor window performance below:
Wind Damage and Thermal Expansion
Strong winds, in conjunction with thermal expansion and pumping, can cause window seal failure. Thermal expansion happens when the gas trapped between the glass panes of multi-pane windows—and other window components—expand and contract as temperatures increase and decrease respectively. This results in the cycling of pressures within the windows, also known as solar or thermal pumping. Over time, repeated thermal pumping can weaken the seal on window glass. And if your windows are exposed to gale-force winds, their sealing might even fail.
Important note: Window seal failure can reduce your window’s performance. If the window sealing is damaged, the trapped argon or krypton gas—which is responsible for preventing heat transfer—will be able to escape, lowering your window’s overall energy efficiency. That’s why it’s highly recommended that you replace damaged windows with an energy-efficient window replacement.
The Warning Signs of Window Seal Failure
How can you tell if your windows’ sealing has been damaged? Here are the warning signs to keep an eye out for:
- Foggy glass – Moisture might infiltrate the space between the panes of damaged windows, fogging up the glass.
- Glass distortions – Window leaks can cause sections of the window pane to collapse, creating distortions in the glass.
One more thing: To make sure your window is installed properly, only reputable window installers should handle their installation.
