If you have foggy windows it doesn’t necessarily mean that you have to rip them out and replace them. Our foggy window repair service procedure can give your windows a new lease of life and extend their lifespan by up to twenty years.

Foggy windows are caused by a phenomenon known as solar pumping. Your windows are not fully hermetically sealed if they were they would explode when the sun heats them up!

During the day, sunlight heats the space in between the two (or three) panes of glass in your window which causes pressure to build up in the void. Tiny amounts of air are forced out through the semi-permanent seal.

In the evening the window begins to cool and this causes low pressure within the window which results in the opposite effect. Air is drawn back in from outside. This air naturally contains tiny amounts of moisture which is absorbed by the silica desiccant in the window cavity. Over a period of years, this cycle of solar pumping will mean that eventually, the silica desiccant will have absorbed all the moisture it can since it has become fully saturated.

Now there is nowhere else for the moisture to go, so it starts building up on the glass inside the void creating the foggy effect.

Windows are actually designed with a certain lifespan in mind since you don’t want exploding windows. Eventually, ALL thermal windows will fail. How long the process takes is dependent upon the quality of the silica desiccant used within the spacer bar.

Once fogging occurs the damage will only get worse. More and more moisture builds up reducing the insulating property of the window and will eventually damage the glass. At this point, you will usually need to replace the glass or the complete window.
