AKRON, Ohio _ Marie Poling thought she was looking at an expense of thousands of dollars to replace all the windows on her Northfield Center Township, Ohio, house.

The insulated glass in the home's bay window had gotten foggy, and she figured her only option was new windows.

Then she found out about a process that removes the moisture from inside thermal pane windows. So for a few hundred dollars, she has a clear view once again.

"It was cheaper, much easier, and very fast," Poling said. "It was awesome."

Poling's bay window had experienced a failure of the seals in its insulated glass units, a common malady of thermal-pane windows.

Those types of windows are made by sealing air inside two layers of glass. Over time, expansion and contraction cause the seal to weaken and eventually fail, allowing water vapor inside. When that vapor condenses on cold glass, it creates a foggy appearance.
