Why is My Double Glazed Window Misted?
Double glazing is a fantastic method to boost the efficiency of your home and ensure optimal energy efficiency. If you notice that your windows are misting, it is a sign of a broken window seal.
This allows moisture to get into the insulation area of your window. This will drastically reduce their performance. Fortunately, this issue is relatively simple to fix.
What is it?
There may be condensation on the exterior of your double glazed windows from time to time particularly when it's cold and windy. This is a normal indicator that your windows are working well, keeping cold out and the heat in. It can be easily cleaned away, or you can leave it to go away on its own.
If your double-glazed window has a tendency to mist on the inside this is more of an issue. This usually means that the seal on your double glazing has broken down, or 'failed' as it is referred to in the field. Moisture may get in between the two glass panes in the case of a double-glazed unit that has failed. This could cause the argon,xenon or the krypton gas used in these windows to leak out too. After this happens the high-density gases lose their insulation properties and your window will no longer function as a sealed unit.
One of the main reasons for a window's seal to wear out is normal wear and tear over years. This is due to the constant expansion and contraction of the gases inside your double-glazed windows as temperatures change. Double glazing seals can be damaged using abrasive chemicals on them.
If the seal on your double-glazed windows is broken this means warm air can escape from between the glass panes and cool air could enter, causing the condensation of moisture to occur on the spacer bar in the glass unit. This is commonly described as a "blown window' and could cause costly energy bills throughout the winter.
This problem can be solved by replacing the glass units in your double-glazed windows. This is a more cost-effective alternative than replacing the entire window. It also guarantees that your home is properly sealed and insulated. It is also important to ensure that the company replacing your double-glazed windows is insured. This will protect you in the event of any unexpected issues.

Understanding the causes of condensation is essential to understand how best to deal with it. Condensation occurs when the surface temperature of a glass is below the dewpoint - the temperature at which the water vapour from the air turns into liquid water. This is the reason it is most likely to occur in the evening or early in the morning, when the dew point is at its highest and the air outside is warmer than the glass's surface temperature.
Condensation within double-glazed windows is likely to become more frequent as the weather becomes colder and humidity levels rise. It is a normal phenomenon, and doesn't mean that your double glazing is in a problem. If the condensation only appears on the outside of the window and disappears when sun comes up there is no reason to worry.
Double-glazed windows that have been damaged or faulty aren't as insulating as they should, which could lead to higher bills. If the seals have been damaged, water can get between the two panes and cause an evaporation.
There are many reasons for misted double glazing, however there are some that are essential to think about.

Damage to glass or water stains caused by the trapped moisture between the two panes could be the next step. This could be due to damage caused during installation or just gradual wear and tear that occurs over time. This could indicate that your window is coming to the end of its lifespan and needs to be replaced in order to increase the insulation of your home.
