insulated glass unit replacement 6

We had to replace an insulated glass unit after noticing a persistent fog between the panes. The old seal had failed, letting moisture in and ruining the window's clarity. Our contractor measured the existing frame, ordered a new double-pane unit with low-E coating, and swapped it in about an hour. The difference is immediate — no more condensation, better insulation, and the room feels warmer already.
