Before diving into repairs, it helps to comprehend what a double glazing unit (frequently called an Insulated Glass Unit or IGU) really is. An IGU includes 2 (or sometimes 3) panes of glass separated by a spacer bar around the edges. The gap in between the panes is filled with air or an insulating gas like argon, and a desiccant inside the spacer bar soaks up any moisture.

3. Sagging or Misaligned Openings

In time, the weight of the glass can trigger the sash to drop, making the window hard to open, close, or lock appropriately. This is usually an issue with hinges, tracks, or the need for “toe-and-heel” re-glazing.

4. Broken or Cracked Glass

Impact damage, thermal tension, or structural movement can crack the glass. Unlike single-pane glass, a broken double-glazed pane compromises the entire system’s thermal performance and safety.

5. Faulty Hardware

Deals with, locks, and hinges sustain a great deal of wear and tear. A damaged lock compromises home security, while a snapped deal with makes the window entirely unusable.
