- A spacer bar: A hollow metal or plastic frame that runs around the border of the glass panes.
- Desiccant: Moisture-absorbing crystals loaded inside the spacer bar to keep the cavity dry.
- The gas fill: Often argon or krypton gas caught between the panes to improve thermal insulation.
- Main and secondary seals: Usually made of polyisobutylene and silicone, these seal the system hermetically to avoid air and wetness exchange.
When any of these elements fail, the performance and look of the window are compromised.
Common Double Glazing Problems
Double-glazing issues usually manifest in a couple of distinct ways. Recognizing these issues early can prevent small issues from turning into significant structural failures.

When the temperature varies, this moisture condenses on the within the glass.

|---|---|---|
| Misted/Foggy Glass | Replace the IGU (sealed unit) only | Moderate (No frame replacement needed) |
| Drafty Seals/ Gaskets | Change rubber weather-stripping | Low (DIY friendly) |
| Broken Handles/ Hinges | Replace hardware elements | Low to Moderate |

Step 4: Installation of the New Unit
- Setting blocks are placed at the base of the frame to support the weight of the new glass.

Safe DIY Tasks:
- Adjusting Hinges: Most modern-day uPVC windows have adjustable hinges. If a window is dropping or capturing, tightening the adjustment screws with an Allen key can resolve the issue.
- Changing Handles: Swapping out a damaged handle is generally as easy as unscrewing 2 bolts, getting rid of the old deal with, and screwing in a new among the same design.
- Oiling Moving Parts: Applying a silicone-based spray to hinges, locks, and tracks keeps mechanisms running efficiently.

- Fixing Structural Frame Issues: Incorrectly straightening heavy window frames can cause the glass to shatter due to uneven pressure.
Advantages of Repairing Instead of Replacing
