Why Is There Condensation Between Window Panes?

Why Trapped Moisture Points To A Window Problem

When fog or moisture shows up between two panes of glass, the insulated glass seal has usually broken down. It is a separate problem from exterior condensation or a damp sill after rain.

In a double-pane or triple-pane window, the space between the glass layers is supposed to stay dry and sealed. Once that seal fails, outside air and water vapor can get into the gap.

What Breaks The Window Seal Over Time

A window seal usually fails from years of expansion, contraction, and daily wear. Coastal weather can be hard on insulated glass, especially in homes close to the bay.

A few common factors show up again and again:

• Repeated heating and cooling that stresses the seal
• Moisture intrusion around old glazing or deteriorated sash components
• Movement, settling, or installation problems that distort the unit
• Sunlight that breaks down materials over the years
• Impact damage from storms or debris, even if the crack is small enough to miss at first
