The truth is that condensation is typically harmless, but you’ll need to keep an eye out in case problems are looming. Here is what to keep in mind when condensation is a normal occurrence and when you need to take action.
What Causes Window Condensation?
Condensation forms on every window. It doesn’t matter if the window is made of vinyl, wood, or even aluminum—you’ll eventually find condensation on its surface. This is because condensation is primarily related to the glass surface, which is the place where the water vapor collects. Most times, condensation can be cured with an adjustment of indoor temperature. Sometimes, though, it’s not quite that easy.
What’s the Trouble with Window Condensation?
Window condensation might seem like a simple drawing board for kids to draw smiley faces, but it can damage window sills, paneling, and even sheetrock. It can also damage walls, wood frames, and destroy the surrounding insulation.
How Does Moisture Form on the Glass?
There are several instances that cause condensation to form on your windows.
First, consider humidity. All air contains moisture, but the warmer the air, the more water vapor it holds. If warm air meets a cold window, the temperature will drop and it releases the vapor. This is when condensation forms on the window.
Double pane windows will get condensation on the glass at around 25-40% humidity. If your house is properly ventilated, you won’t have to be very concerned about humidity.
The best course of action in this case is to keep your indoor relative humidity at less than 40%.
When is Condensation Not Harmful?
Occasional condensation that appears on the interior or exterior of your glass normally isn’t harmful. The key is to consider how quickly it disappears. If you notice that it goes away on its own, you are probably just experiencing normal condensation.
When is Condensation a Problem?
There are several flags you’ll need to keep your eye on when condensation becomes a problem. These signs include:
· Condensation between the frames: this is a sign of seal failure. The seal will need repaired by the manufacturer, or the entire window may need replaced
· You notice rotting around the window sill or the window frames
· You find damp patches on your walls, which indicates that moisture has collected on the wall for a prolonged period of time
· You may also notice peeling wallpaper or black mold growth
If you are finding some of these red flags and your windows are old, consider new window installation. Universal Windows Direct can help correct window condensation problems in Charlotte, North Carolina. Contact us to learn more.
