If the condensation is only in a small area of your window frame, you can usually get rid of it by wiping it off quickly and often. If you see condensation over a larger portion of the frame, it could mean that the seal has been damaged and windows are not as efficient in thermal efficiency.
It can be caused by many causes however the most common is excessive humidity or poor ventilation in your home. Double-glazed windows tend to show more condensation than older single pane windows since humidity is able to form droplets of water on cold surfaces. If your bathroom or kitchen are especially humid, you may require installing an air vent to reduce the humidity levels.

Foggy Glass
Foggy windows can be a sign of a failed seal in double-pane windows. Double-pane windows have two glass panes with a space between them. This space is filled with energy efficient gases such as argon or Krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. If the seal is damaged, moisture could get in and create fog. Foggy windows can make your home less efficient and look unattractive.

You should contact the company that sold you the double glazing if you discover it difficult to open. Most companies offer warranties on their products that last for an agreed period of time. Some even offer lifetime guarantees.

Cracked Panes

A crack in a double-glazed window might seem like a minor issue, but it can actually cause significant damage. It's crucial to have the crack fixed as quickly as you can to avoid further damage, particularly if it's on inside of the glass.
Double-pane windows are made up of two glass panes assembled together with a gap in between that is filled with an inert gas like argon or Krypton. This is to ensure that heat from your home doesn't get transferred through the glass. The gas slows the heat transfer, which means that the warm air from your home may move through the window at a slower pace than if there were nothing between the panes of glass.
It is essential that windows are properly installed and with a good seal. The windows must be installed by a licensed glazier who can install the glass panes with a secure seal to ensure they are insulated as effectively as possible. If the seal on the window is not working and gas is trapped inside the panes might leak out and diminish their insulation properties, which could lead to cracks between the panes.
Another reason that causes broken double-pane windows is due to poor installation, which may lead to the glass expanding and contracting at different rates. This could cause stress cracks to appear over time, weakening the glass. If this happens, you should seek out a glazier who can replace the broken glass with one more appropriate for your home.

Leaking Seals
The IGU consists of three or more sheets of glass that are annealed or glass that has been tempered. The IGU is held in place by a combination of aluminum spacers, polyurethane. This creates an airtight seal that prevents moisture from getting into your home. In time, however the seal could break down which allows the draughts and water to penetrate into your living spaces.
This is typically caused by the natural expansion or contraction of materials used to create your window. The sealant, either silicone or polyurethane, can expand and contract slightly in response to variations in humidity and temperature, putting the IGU at risk of breaking down. If the seal is damaged the insulating fill gas could leak leaving your windows with the appearance of fog and draughts which can reduce the efficiency of your home.
When a window seal fails, it can also result in condensation or water between the panes, which you are unable to wipe away. In some cases the water may leave permanent marks on your window glass.
