Identifying 3 Types of Window Condensation


We’ve all seen it. That annoying steam that gradually builds up on our window panes. And that so-called vapor pressure that persistently tries to escape the existing humidity to enjoy the dry air. Well, for most of us, we know it as window condensation.

Window condensation is a home phenomenon that happens in the midst of extremely hot and cold situations. It is characterized by the transformation of heat into its liquid state, more visually explained as the moisture we see on our window panes. But did you know that there are 3 types of window condensation?

Internal Window Condensation

During the year’s coldest season, window condensation takes place on the interior window panes. They are visually seen as little droplets of moisture pasted on the window glasses. How is this phenomenon explained?


Due to the controlled humidity operated inside our homes to adjust to the artificial heating used during winter, moisture tries to escape from the humid air to join the drier winter air outside. Partially, it is caused by modern insulation and construction that disallows internal moisture to seep through a home’s exterior. A little home insulation repair through the help of window installation and replacement contractors will fix the problem.

External Window Condensation

On the other hand, the opposite happens in the presence of extreme heat – in summer, most especially. Instead of finding the moisture on the inner window panes, window condensation poses without hesitation on the outer planes. The same logic applies from the first type of window condensation.


But what makes it less threatening from the first one is that it doesn’t trigger any more risk to your home’s interior, such as the ceiling, the bathroom, the kitchen and others. Moreover, this phase doesn’t last long. When the temperature starts to turn low, the window moisture won’t be as visible.

In-between Window Condensation

However, there’s one kind of window condensation that doesn’t follow the conventional season-based appearances of vapor pressure on the window panes. On rare occasions, the moisture appears in between the panes of an insulated window. This window condensation indicates a significant problem with the airtight seal. Window replacement is the ideal solution for this.


Regardless of the season, as long as temperature differences occur between the interior and exterior, window condensation is bound to happen. But it shouldn’t be approached as an incurable problem. Because the truth is, there are proven ways to counter it. It’s only a matter of dealing the problem professionally, which involves calling the right people – the experts of window installation and replacement, so to speak – to help you get through it.
