How Strong Winds Can Damage Your Window Seals

If you notice your multi-pane windows are getting foggy, this might mean that your window seals have been damaged. This issue might have occurred because you live in a windy area or have recently experienced strong windstorms or high winds. 

Damage Your Window Seals

To find out if wind can damage your window seals, read this article from Renewal by Andersen® of New Jersey, one of the leading window companies known for their quality bow and bay window designs. In this post, we will explain how strong winds can affect the performance of your window.

The Function of Multi-pane Windows

Before anything else, you should first understand how multi-pane windows are built as well as their function. Multi-pane windows consist of a window frame that holds the insulated glass, or IG units. These windows contain gas without moisture, which doesn’t conduct heat as well as the air outside of the window. This means that less heat enters or escapes your home.  

Over time, your multi-pane windows are exposed to changing temperatures. For instance, in the evening, the window components, including the gas between the panes of glass, are lower in temperature. In the morning, your windows will increase in temperature, especially those that have direct sunlight exposure. This constant changing of temperatures causes the gas to expand or contract, a process known as “solar pumping or “thermal pumping.”

Solar pumping will eventually strain the seals between the glass, causing small fractures and leaks. To prevent this, manufacturers add a desiccant between the panes in addition to the seal. The desiccant will mitigate any moisture that finds its way into the IG unit. However, the desiccant is limited and, with time, it becomes saturated. This leads to window seal failure as well as the fog effect you see between your window panes.

The Effect of Heavy Winds

While the temperature may be the biggest problem you’ll face with your window seals, wind damage can also affect their function. If your window is old or drafty, the heavy winds can be the final push to its failure. As such, you should immediately schedule a window replacement if you notice any issues with your window.

Additionally, windblown debris can be particularly damaging. Debris can cause property damage on any part of your house, but you should also check your window seals to make sure debris will not break the seal. Strong winds during a rainstorm can also be a factor since moisture can be sucked in between panes when window seals have already been damaged. 

However, it’s important to note that the effect of heavy winds on the performance of your window can be complicated. Therefore, you might need to have your window examined by a professional. You should also consider other factors, such as window maintenance, material properties and manufacturing issues, when identifying the cause of your window damage.
