The windows throughout your home are a gateway to the outdoors, a way to draw light in while you appreciate the view of your garden, yard or scenery. The last thing you need to see is a sweaty window covered in a layer of condensation.
Not only are windows coated in condensation unattractive, they also can be a sign of a more substantial air-quality issue in your home. Luckily, there’s multiple things you can do to correct the problem.
What Produces Condensation on Windows
Condensation on the inner layer of windows is formed by the moist warm air throughout your home hitting the colder surface of the windows. It’s notably common in the winter when it’s much colder outside than it is within your home.
Inside Moisture vs. In Between Panes
When discussing condensation, it’s important to recognize the contrast between moisture on the inside of your windows in comparison to moisture in between the windowpanes. One is an air-quality issue and the other is a window issue.
- Moisture within a window is produced from the warm humid air in your home forming against the glass.
- Existing moisture you find between windowpanes is formed when the window seal stops working and moisture gets in between the two panes of glass, in which case the window should be repaired or replaced.
- Condensation in the windows isn’t a window problem and can instead be solved by adjusting the humidity in your home. Different things produce humidity inside a home, like showers, cooking, taking a bath or even breathing.
Why Sweating Windows Can Be an Issue
Although you might consider condensation inside your windows is a cosmetic issue, it can be evidence your home has higher humidity. If this is the case, water might also be condensing on window frames, cold walls or other surfaces. Even a thin film of water can cause wood surfaces to mildew or rot over time, increasing the growth of mildew or mold.
How to Lower Humidity Inside Your Home
Fortunately there are several options for removing moisture from the air inside your home.
If you have a humidifier running in your home – whether it be a small-scale unit or a whole-house humidifier – lower it further so the humidity inside your home comes down.
If you don’t have a humidifier going and your home’s humidity level is excessive, think about purchasing a dehumidifier. While humidifiers put moisture inside your home so the air doesn’t become too dry, a dehumidifier pulls excess moisture out of the air.
Small, portable dehumidifiers can eliminate the water from a single room. However, these units require emptying out water trays and usually service a fairly small area. A whole-house dehumidifier will eliminate moisture from your entire home.
Whole-house dehumidifier systems are regulated by a humidistat, which permits you to set a humidity level precisely like you would choose a temperature via your thermostat. The unit will start immediately when the humidity level overtakes the set level. These systems coordinate with your home’s HVAC system, so you should contact qualified professionals for whole-house dehumidifier installation .
Additional Ways to Lower Condensation on Windows
- Exhaust fans. Putting in exhaust fans around humidity hotspots such as the bathroom, laundry room or above the kitchen range can help by extracting the warm, moist air from these spaces out of your home before it can raise the humidity level across your home.
- Ceiling fans. Turning on ceiling fans can also keep air flowing within the home so humid air doesn’t get caught up in one spot.
- Opening up window treatments. Pulling open the blinds or drapes can decrease condensation by preventing the humid air from being stuck against the windowpane.
By reducing humidity inside your home and circulating air throughout your home, you can take advantage of clear, moisture-free windows even in the winter.
