Seals that have been damaged
The window seals wear down over time and allow argon gas or krypton to escape from between the panes of double- or triple-paned windows. If you have a broken seal, air from outside is entering and the argon which helps insulate your home is being emitted both of which can be detrimental to energy efficiency.
Window seals are susceptible to damage due to extremes in humidity, temperature and pressure. These changes can cause the glass to expand and shrink. This can put pressure on the seals. This is especially true when you have pets or children that accidentally hit your windows.
If the seal on your window breaks, it's a good idea to have the problem examined by a professional as fast as you can. If you put off the repair for too long, the argon or Krypton gas could escape completely, and this will significantly reduce your window's insulating properties.

Condensation
Condensation is among the most frequent issues associated when it comes to double glazing, particularly in older properties.

It is more likely to occur during the night or during the early morning hours, when temperatures are the lowest.
Fortunately, condensation in double glazed windows is easily fixed and usually does not require replacement of the entire window or door. The'spacer bar,' which is located between the two panes of most double glazing, is filled with desiccant. It is extremely absorbent and draws in any moisture that gets into the air gap.' If the spacer bar is filled with moisture, it could leak into the window frame where condensation forms.

Mist
