RV Windows: Why Is My Window Foggy?

Most likely your window is foggy because your sealant failed. This is most likely due to a tiny hole, leak, or crack in the rubber sealant. This allows moisture to seep through those cracks.

Seals break for many reasons. As a window ages, the sealant breaks down with normal wear and tear. The sealant can also break due to improper drainage around the window. The bottom of the window traps water. This further erodes the sealant.

Sun plays an important factor in sealant deterioration, too. Each time your windows get direct sunlight, your panes expand and contract due to a process called, “solar pumping.” With all the movement of the RV rumbling down the road along with the sun, wind and rain, the sealant can begin to break down. Double pane windows have insulated airspace between the two glass panels complete with desiccant. The desiccant absorbs moisture. Eventually the desiccant in between the argon panels can’t absorb any more water. Water droplets remain suspended in air. As a result, your windows look foggy, milky or streaky. The milky color is from calcium deposits.
