Condensation in Windows
Foggy windows are more than just ugly to look through. The window condensation reduces the window’s ability to insulate you from outside temperatures, defeating the purpose of having thermal pane windows!
Furthermore, moisture begins to rot and corrode your glass if not fixed. As fog turns into condensation it leaves white vertical drip lines, etched panes and eventually large patches of white haze.
Eventually every thermal pane window will lose the ability to absorb condensation and fog up. Foggy windows, or windows with condensation and moisture, are primarily due to the inability of the silica desiccant materials in the thermal window cavity (as shown above) to absorb moisture that naturally builds over time. Windows are manufactured with a specific moisture absorption life span based on the quality of the desiccant materials used in their construction. Window manufacturers know that all windows will eventualy fail.
Our window treatment can solve most of these problems and is backed by our 20 Year Warranty.
Know the Four Stages of Window Failure
Stage 1 - Foggy Window or Window Condensation
When the window reaches a threshold saturation point, moisture becomes visible as fog or condensation resulting from the falling dew point between the glass window panes. In the early stages of visible failure, a mist or fog may appear and disappear through the natural cycle of evaporation.
Stage 2 - River Bedding
As the moisture saturation point is further exceeded, permanent window damage can begin. When moisture becomes permanent, it will run down the surface of the glass using the same path as the first drop. Over 6 - 12 months this cycling activity will physically etch the surface of the window glass leaving a “river bedding” effect. Note: Water droplets collect moisture on the ride down the glass surface meaning that riverbed damage is typically more aggressive at the bottom of the window.
Stage 3 - Silica Haze
Silica haze is a destructive chemical growth that can appear within a window even if it has never shown any visible signs of moisture. A closer look at the window will show unusual, snow-flake-like patterns with cross hatch patterns running at a 45 degree angles or a white chalky haze that begins to grow over the surface of the glass.
Stage 4 - Riverbed & Silica Haze
In addition to the dry type silica haze, windows that have been consistently moist or wet will also develop silica haze and an additional damaging effect called "river bedding". The damage caused by silica haze and river bedding is irreversible if the glass surface has been physically damaged.
