Why is There Ice on My Windows?
Although waking up to a blanket of snow outside can be beautiful, it's a different story when you're getting ice and frost on the inside of your windows. Luckily, modern dual and triple pane windows make ice on your windows less common than long ago, but it's a reality that some Fort Wayne homeowners still face today. If you're discovering frost on your windows this winter, there are several steps you can take to improve the situation. Here's why window frost forms in the first place:
Is there a Leak Inside of Your Window?
When ice appears on the inside of your windows, a lot of homeowners immediately think that water is leaking inside somehow. Window leaks can sometimes be the culprit, but humidity in the air is often one of the causes for frost. Another issue involves dew pointâ€”which is the temperature when window condensation occurs.
When warm air mixes with cold air, the result is condensation.
Why are Your Windows Freezing?
Now that you understand a few of the natural factors that cause your windows to freeze in the winter (humidity, dew point, and condensation), it's time to understand how other factors play into the issue.
First, your window's thermal performance plays a big role in terms of insulation. It's important to remember that no window provides equal insulation as a solid wall, but some windows are more effective than others against condensation. It's inevitable that you'll find temperature variation between the air in your home and the surface of the glass.
As the outdoor temperature continues to drop, the surface temperature of the window glass drops right along with it.
Second, indoor humidity will also play a role in freezing your windows. Since warm air holds more moisture than cold air, lowering the temperature on your thermostat can have a direct impact on ice forming on the glass.
Air leakage is another culprit for wintertime window frost. When your window leaks air, this often points to installation issues or even seal failure. If cold air is leaking through from the window frames, it can ultimately freeze the condensation that's forming on the inside of your windows.
How to Prevent Ice on Your Windows
One way to prevent ice from forming on your windows is to control the humidity levels in your home. The ideal indoor humidity for 20 to 40 degrees Fahrenheit (outdoors) is no more than 40%. If it's between 10 to 20 degrees, 35% humidity is best. If the outside temperature is between 10 and 0 degrees, 30% is ideal.
It's also smart to checking your window seals and caulking every year. Be sure that drafts aren't making their way indoors and look for signs of moisture damage.
