Fogged and Cracked Window Repair

Insulated Glass Units (IGUs), sometimes referred to under the brand name “Thermopane” and popularly known as double-pane windows, are two panes of glass separated by a spacer, with gas or moisture removed air taking up the space in between. These double-pane windows can provide substantial energy savings due to reduced heat loss, and are much better noise insulators than their single-pane cousins.

As with any product, double-pane windows glass can break down over time, which can lead to a fogged window. A fogged window typically looks like there is moisture or condensation on the glass, but upon inspection, the moisture is on the inside surface of the window panes, and therefore not able to be wiped away. This is usually indicative of a broken seal. If you need a broken, fogged window repair, give us a call and we can fix your window in no time!
