Your windows can look foggy over time. This may occur due to a variety of reasons, and one of the most common culprits is a broken window seal. That is why window professionals often check this component, especially if the region experiences a lot of wind, or there have been high winds in the area recently.
Winds are not usually the immediate cause of window seal failure, but they may have generated the breaking point for a window that has accumulated exposure to various elements over the years. Being exposed to elements, such as heat, rain and snow, over a given period can eventually take a toll on the window, especially on the window seal.
If you have multi-pane windows at home, an overview of how these windows work will help you gain a better understanding of how to determine if condensation on your window is already a cause for concern.
How Do Multi-Pane Windows Work?
Basic knowledge about how multi-pane windows work enables you to have a better grasp of a window’s risk of wind damage and be able to care for your window properly. That said, there are two fundamental things that you need to know: how multi-pane windows are designed or built and the load that these windows can sustain per day.
Typically, multi-pane windows are built with a frame that is designed to hold insulated glass (IG) units. Each of these IG units have two or more layers of glass with moisture-less gas caught between them. The trapped gas is used to conduct heat less effectively than outside air, thus reducing the amount of heating and cooling needed inside your home. Because of this quality, windows are also able to resist fogging and frosting – an added benefit that prevents your window from being unnecessarily exposed to moisture. That said, if your multi-pane window suddenly becomes foggy, this could indicate a problem that should be checked and confirmed immediately. Window replacement may be necessary depending on the severity of damage.
How Can Strong Winds Damage Window Seals?
Windows can normally stand up against a variety of weather conditions and temperatures, and they can even be custom-made for specific climates. Nevertheless, changing temperatures can take a toll on the windows after some time. For instance, temperatures are often lower in the evening, so the window components tend to cool down as well during the nighttime and then heat up during the day.
The trapped gas in multi-pane windows usually expands in warmer temperature and contracts in cooler temperature. This creates a cycle of pressures that go on every day and could eventually affect the window seals by causing faster deterioration. It can also result in small cracks that could potentially act as entry and exit points of the air between the panes.
Manufacturers are well aware of these risks, and they expect fractures to develop and grow in the window seals. That is why some manufacturers also place a desiccant between the glass panes in addition to the seal. The role of the desiccant is to mitigate any moisture that reaches the IG unit.
Take note, however, that the capacity of the desiccant is limited. Over time, the desiccant will become saturated, and moisture will be left to condense inside the IG unit. This scenario is bound to happen in any IG window, regardless of whether or not it has been exposed to one or multiple severe storms.
That said, if your window seals are already dealing with such circumstances, strong winds could possibly make the situation worse and eventually cause a complete failure of the window seals. Make sure to watch out for this, especially if the wind comes with debris.
