How to Prevent Condensation Between Double Pane Windows in Texas

Why Double Pane Windows Fog Up From The Inside

If the moisture is trapped inside the glass unit, the window has likely lost the airtight seal that kept the insulating gas and dry air where they belonged.

UV exposure is another quiet problem, since direct sun can age sealants and shorten the life of older units, especially on west- and south-facing elevations.

Once moisture gets between the panes, it usually cannot be wiped away from the inside or outside, because the problem is sealed inside the insulated unit.

Moisture trapped between the panes points to a broken seal and, in most cases, a failing insulated glass unit.
