My Double Pane Window Is Foggy

But before we look at how to make your foggy windows sparkle again we need to look at how they are constructed in order to understand the nature of the problem of fogginess.

My double pane window is foggy. As many homes have double pane windows some will eventually get foggy. Then glue small plastic tubes in the holes to prevent further moisture from getting into the window. Check to make sure that the hazy film is not on the outside by cleaning the glass first. There are things that one can do about it ranging from cheap and temporary to expensive and permanent.

While the foggy windows may evaporate and clear up from day to day if left untreated calcium in condensation can etch the glass and leave a permanent hazy appearance on your windows. The haze can be severe like in the photo above or less obvious unless there is glare on the surface as in the photos below. As the sun hits the window the trapped moisture condensation get released. In these situations it s as simple as replacing the insulated glass unit.

Such windows are also commonly called thermal windows. It s also important to note that foggy windows are more than an inconvenience. Due to the design of a double pain window it is prone to fogging up inside. The downside to double windows is that they can be prone to collecting condensation that results in parts of the window fogging up and decreasing visibility.

If you have window panes that are clouded over it s likely that they are double pane insulated and have lost the inert gas sealed between the two panes of glass. This is an unfortunate flaw of many double pane windows. Whether it is just a simple sealed glass sandwich of two glass panes or a more sophisticated igu with coatings and inert gas filling the space between panes these windows can easily double. Foggy windows are a result of moisture buildup between double paned windows.

The bane of double pane windows is the dreaded f word. When double pane windows fog up they look really dirty and reduce visibility through the windows. Foggy double pane windows are a nuisance for several reasons not least because the fog makes it hard to see out of them. The wood gets too wet and starts to rot and eventually the glass seal breaks down.

The moisture is sucked out and a defogger device is attached to the window. The procedure typically involves drilling a hole into the frame and pumping a cleaning solution inside. When condensation between double pane windows forms the seal on the glass is broken. If multiple pane windows appear misty or foggy it means that the seal protecting the window assembly has failed.
