Double or triple glazing hermetically sealed glass units whether fitted to a uPVC profile or a timber frame can become defective over time. This is more likely to happen to the early versions of glazing which fall below the efficiency level of today’s modern glass. Modern units perform to a higher specification to meet the needs of the increasingly energy aware consumers.
How can you tell that you have a failed glazing unit? With close inspection of your window, you can spot the following signs that show a faulty hermetically sealed glass unit:
- Condensation inside panes
- Leaking window
- Broken or chipped glass
- Draughts and escaping heat
