One of the most important but least talked about matter about windows is condensation. This refers to the drops of water on the surface of the glass. The liquid comes from the warm air, which carries generally invisible water vapor. When the moist air meets a colder surface, the excess moisture condenses and causes the sweating.
For the first part of this series, Renewal by Andersen® of Kansas wants to share further light on condensation. Find out whether or not it’s a cause for concern when you notice it on your windows in Wichita:
Is Exterior Condensation Bad?
In double-pane units, exterior condensation happens when the sweating occurs on outside surface of the interior glass. This is just a form of dew, which is a natural phenomenon. This is the very same condensation you see on your vehicle’s windshield on mornings.
Although it may seem like a red flag, exterior condensation may even indicate that your windows in Derby are energy-efficient. It can be a sign that the outer pane of your window is properly insulated from the indoor heat, making its surface temperature cool.
How about Interior Condensation?
On the other hand, the sweating or fogging you see on the outside surface of the interior glass is due to excessive humidity. Interior window condensation is more of a symptom rather than the main issue. If too much sweating happens on your interior window glass, chances are that it’s also happening in other areas of your home. This indicates moisture damage, which you need to address immediately.
When is Condensation a Window Issue?
The only type of window condensation you should worry about is the one that happens in between the glass panes. The empty space in the middle of the two sheets of glass has an insulating gas that acts a cold air barrier. It acts as an invisible wall that blocks and minimizes the transfer of heat, allowing you to better control your indoor temperature with less energy.
To continue doing its job, the spacer system holds the glass panes securely to create a gas-tight seal and prevent moisture infiltration. Condensation inside the glass indicates seal failure. The moment the water vapor penetrates the space between the glass panes, your window’s insulating value lessens.
You can properly deal with condensation if you know when to act. Renewal by Andersen of Kansas can help you assess your old windows and recommend energy-efficient options as replacement. You can learn how our windows in Topeka prevent condensation in the next part of this series.
