Double Glazed Window Misted: 10 Things I'd Love To Have Known Earlier
Why is My Double Glazed Window Misted?
Double glazing is an excellent way to increase the efficiency of your property and secure optimal energy efficiency. However, 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 section of your window, which will drastically reduce their performance. This problem is easy to repair.
What is it?
You may see condensation on the exterior of your double-glazed windows at times, especially if it's very cold and windy. This is a typical sign that your double glazed windows are keeping out the cold but also let in heat. It can easily be wiped away, or let it clear by itself.
If your double-glazed window has a tendency to mist on the inside, this is a more serious issue. This could be a sign of a broken seal or failure in your double glazing. The moisture can get inside the two panes of glass in double-glazed units that have failed. This could cause the argon,xenon or the krypton gas used in them to leak out too. Once this happens the high-density gases lose their insulating properties and your window is no longer a sealed unit.
Natural wear and tear is one of the main reasons that cause seals to fail on windows. This is due to the constant expansion and contraction of gases inside your double-glazed windows when temperatures fluctuate. Using abrasive chemical cleaners on your double glazing can cause damage to the seal and lead to it failing in time.
If the seal on the double-glazed windows you have is broken, warm air can escape through the glass panes and cool air can enter creating moisture on the spacer bars inside the glass unit. This is referred to as a "blown" window and can cause costly energy bills during the winter.
Replacing the glass units in the double-glazed windows you have can solve this issue. This is a far more cost-effective solution than replacing the entire window and it can ensure that your home is properly insulated and sealed. It's also a good idea to make sure that the business you choose to replace your double glazed windows is insured as this can protect you in the event of any unforeseen issues regarding the installation.
What is the reason for this?

It is crucial to know the causes of condensation in order to understand how to best deal with it. Condensation occurs when the surface temperature of a glass falls below the dewpoint, the temperature at which the water vapour from the air changes into liquid water. It is therefore common to see it at late at night or in the early morning, when the dewpoint is high and air temperature is higher than the glass's surface.
Condensation in double-glazed windows will become more frequent as the temperature drops and humidity levels rise. It is generally a natural phenomenon and does not necessarily mean that your double glazed windows are in a problem. If the condensation is only visible on the outside of your window and disappears as the sun rises, there is no reason to worry about it.
Double-glazed damaged or broken windows will not insulate your home as well as they ought to and this can result in higher energy costs. If the seals are damaged then moisture may pass through the two panes of glass and eventually cause the misting effect.
There are many causes of misted double glazing, however there are a few that are essential to think about.
The first sign of a problem with your double-glazed windows is when you begin to notice condensation forming on the inside of the window. Damage to glass or water stains caused by moisture trapped between the two panes could be the next step. This could be due to damage during installation, or simply gradual wear and tear. In some instances this will be a sign that the window has reached the end of its lifespan and needs replacing to improve the overall insulation performance of your property.
