Why Do Window Seals Fail?
A broken window seal allows moisture to collect between the panes of glass, making it appear cloudy and foggy. Over time, the seal can break down enough to allow moisture to infiltrate the areas between double-pane windows.
What is a Double-Paned Window?
Double pane windows consist of two layers of glass with a gap between the two. The gap is usually filled up with some insulating gases, which improves energy efficiency and minimizes heat loss from the buildings. However, the seals break after a long time, trapping moisture in between the panes, thus causing a problem in the form of fogging.
