Comprehending Double Glazing Units
Before diving into repair work, it helps to comprehend what a double glazing system (typically called an Insulated Glass Unit or IGU) in fact is. An IGU consists of 2 (or sometimes 3) panes of glass separated by a spacer bar around the edges. The gap between the panes is filled with air or an insulating gas like argon, and a desiccant inside the spacer bar takes in any wetness.

2. Draughts and Cold Spots
If cold air seeps in around the edges of the glass or through the window frame, the rubber gaskets or seals have broken down or shrunk.
3. Drooping or Misaligned Openings
Gradually, the weight of the glass can cause the sash to drop, making the window difficult to open, close, or lock appropriately. This is typically a concern with hinges, tracks, or the requirement for "toe-and-heel" re-glazing.
4. Broken or Cracked Glass
Effect damage, thermal stress, or structural motion can break the glass. Unlike single-pane glass, a split double-glazed pane jeopardizes the whole unit's thermal efficiency and safety.
5. Faulty Hardware
Manages, locks, and hinges sustain a great deal of wear and tear. A broken lock compromises home security, while a snapped deal with makes the window completely unusable.

| Worn Gaskets/Seals | Repair (Resealing) | Restores weatherproofing at a fraction of a new window's cost. |
| Rotten Wooden Frames | Complete Replacement | If the structural integrity of the frame is gone, repair work are futile. |
| Serious Frame Distortion | Complete Replacement | uPVC or aluminum frames that have distorted will not hold new glass safely. |
