Condensation
Condensation in double glazing isn't just a nuisance but also indicates that warm air is being emitted from your home. This is usually the sign of a broken seal or the deterioration of. It is best to replace the entire window if this is the case.

Humidity can easily create droplets of water on cold surfaces, which is why your double glazed windows are more likely to exhibit condensation than older single-pane windows. If your kitchen or bathroom are particularly humid, you may require installing a vent to help reduce the humidity levels.
If your windows are under warranty, you can call their installer to explain the issue and request to resolve it.

Foggy Glass
Foggy windows are a sign that the seal on double-paned windows has failed. Double-pane windows are made up of two glass panes, with space between them and this space is filled with energy-efficient gases like argon or krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. If the seal is not strong enough it is possible that moisture will seep in and create fog. Foggy windows are not only ugly, but they could also make your home less energy-efficient.

This is a relatively new method and is worth a second look to determine whether it's suitable for your home before you commit to it. It will not, however it will restore the energy efficiency that's been lost due to deteriorated seals.
Cracked Panes
A crack in a double-glazed window might appear to be a minor issue but it can cause significant damage. It's important to have the crack repaired as soon as you can to avoid further damage especially if it's on the inside of the glass.

Double-pane windows consist of two glass panes connected with a gap in between that is filled with an inert gas like argon or Krypton. This is done to stop heat from your home from transferring through the glass. The gas slows the heat transfer, meaning that the warm air from your home will be transported through the window at a slower pace than if there was nothing between the panes of glass.
It is crucial that windows are properly installed and with a good seal. double glazing windows repairs must be installed by a qualified glazier, who can fit the panes of glass with a secure seal to ensure that they're properly insulated to the best extent. If the seal on the window is not working, the gas inside the panes may leak out and reduce their insulation properties, which could lead to cracking between two panes.
Another reason that causes broken double-pane windows can be due to poor installation, which can lead to the glass expanding and contracting at different rates. This can cause stress cracks that develop over time and weaken the glass.

Seals that leak
The IGU consists of two or three parallel sheets annealed glass or tempered. The IGU is joined by a combination of aluminum spacers and polyurethane, which forms an airtight seal between the windows that keeps moisture from penetrating your home. As time passes the seal can fail and allow water to leak in.
This is typically caused by the natural expansion or contraction of materials used to make your window. The sealant, either polyurethane or silicone, will expand and shrink with changes in temperature and humidity and humidity, putting the IGU at risk of breaking down. When the seal breaks down the insulative fill gas can escape and leave your windows with a cloudy appearance and draughts that reduce the efficiency of your home.
If a window seal is damaged it can result in condensation or water between the panes, which you are unable to wipe away. In certain cases the water may leave permanent marks on your window's glass.
