Home What Makes Glass Window Foggy? How to Fix Them?

It is common to find thermal windows in Ottawa homes and offices. It is the energy efficiency of thermal double-pane and triple-pane windows that has made them so popular compared to single-pane windows. However, most homeowners complain about foggy glass windows. Foggy windows not only reduce visibility but also indicate that your glass windows are faulty.

 

Do you ever wonder why window glass becomes foggy?

 

Different reasons lead to foggy windows. To fix this issue, you should understand where exactly the fogging occurs. Depending on its place of occurrence, professionals can take appropriate action to ensure that you have clear windows all year round.

 

Fogging on the Exterior Glass

When fogging occurs on the exterior pane of a window, it means that the temperature indoors is much lower than the outside. For instance, you might notice water droplets on the outer side of the window when you keep your air conditioner on during hot summer days.

 

Fogging on the Interior Glass

When fogging occurs on the interior window glass, the reason behind is exactly the opposite. It typically occurs when it is cold outside and the temperature of your home is higher due to any reason, such as social gathering or room heater.

 

In both cases, fogging is temporary and disappears after some time.

 

Fogging Between the Panes

The main problem arises when fog appears in between the panes of a thermal window. In most cases, fogging stays there for a long time. Sometimes, the fog keeps coming and going. When this happens, it simply implies that you have faulty double or triple-pane windows.

 

The reason why your windows fog up in the space between two or three panes is that the seals that outline the edges of your windows have failed now. When these seals fail, the moisture easily enters and accumulates between the panes.

 

Why do window seals fail?

The three factors that cause wear and tear to sealants are water, heat, and age.

 

When puddles start to form near the bottom of a window, the perimeter sealant is exposed to water and thus, fails sooner.

 

When a window directly faces the sunlight for most time of the day, the sealant is more likely to fail sooner than it would if it stays in the shade. It is because the major difference between temperatures leads to bigger contractions and expansions.

 

If your windows have not been replaced or repaired for a long time, it’s time that you call a professional to inspect your windows.

 

Besides, as time passes, silica desiccant present in the space bar becomes saturated. Its main function is to absorb moisture. Once it becomes saturated, the fogging starts occurring.

 

How to fix the foggy glass window issue?

 

If you want to get rid of foggy, blur windows permanently, you must call a professional for foggy glass window repair. When windows start getting foggy, it means they have lost their inert gases or silica desiccant has been saturated, and their life expectancy is going to end sooner.

 

Various factors, such as wind, atmospheric pressure, temperature fluctuations, working loads, water, sunlight, and moisture can make the condition even worse.

 

Sometimes, not paying attention to foggy windows and getting them fixed can cause windows to break down. The defogging procedure can help you restore the visibility of your window and keep the fog buildup process away for several years.
