Foggy Window

Why is my office window foggy? Why are my house windows cloudy? To respond to these questions, you have to know that all old windows tend to develop condensation from moisture.

If you see fog in your windows and glass panes or condensation building up between the window glass panes, you might have a problem with your window’s insulation.

Your windows are probably exposed to the UV of the sun, and suffering from broken seals.  A new insulated window seal should prevent fogging, but if it doesn’t, you might need to replace your window frame. As you figure out the reason for your fogging windows, check your window seals, glass and sash.

Tanic expert glazers can help you to resolve your foggy window problems.

Why Windows Become Foggy?

Windows are often the first place where condensation can be seen. Window condensation may be an indicator of something entirely different. Your foggy or icy windows may be an indicator that you need to reduce indoor humidity before it causes hidden, costly problems elsewhere in your home. Condensation forms when warm, humid air contacts a cold surface.

Old windows
If your old windows are drafty, those cracks did more than just let in the wind; they allow excess moisture to escape outdoors. After a couple of decades, you may notice fog in your double pane windows that you can’t seem to wipe off.
Heat Exposure
Condensation forms when warm, humid air contacts a cold surface. Moisture is in the air all around us and warmer air can hold more moisture. Since warm air expands, the air inside a double pane window could stretch your seals. Exposure to direct sunlight could deteriorate your window seals over time.
Humidity and water
The perimeter seals are vulnerable to damage when there is too much water build-up near your windows. The most common cause of indoor air humidity is everyday living. Things like showers, baths, cooking, washing dishes, doing laundry, cleaning, and even breathing all add moisture to the air in your home, as much as 15 litres or more per day in some homes.

Foggy windows indicate that the moisture absorbing desiccant materials are fully saturated. From this point on moisture accumulates and circulates between the glass window panes. Therefore, a foggy window indicates the end to a window’s life.

This process can cause insulation to deteriorate your windows. By replacing the Insulated glass units glass of your window, you can improve insulation and saving energy and money.

Almost all thermal windows today use some type of Low-E glass and Argon Gas to improves U-value, the measure of a window’s thermal performance; similar to the R-value of wall insulation.
