Understanding the Culprit: Why Do Windows Get Foggy?

To understand foggy windows repair work, one must initially understand the physics behind the fog. A lot of modern-day domestic windows are Double-Pane or Triple-Pane units, often described as Insulated Glass Units (IGUs).

An IGU consists of two or more glass panes separated by a spacer. The space in between the panes is generally filled with an insulating gas (like argon or krypton) and sealed securely at the edges to keep wetness and outdoors air out.

Nevertheless, over time, window seals deteriorate due to:

Constant growth and contraction from temperature fluctuations.
Direct, extended direct exposure to UV rays.
Poor preliminary installation or settling of the home's foundation.

Since the moisture is caught between the panes, no quantity of Windex and elbow grease on the within or exterior will make it vanish.

The True Cost of Ignoring Foggy Windows
