Replacement
Double glazing misting is a problem that can affect most modern doors and windows. It happens when a sealed unit fails and moisture enters the space between the two glass panes. This could be fogging or condensation, and will not just affect the appearance of your window but also reduce its performance. There are numerous solutions to this issue ranging from drilling and draining the gaps, to complete replacements, but it's crucial that any work is performed by a skilled trade professional who will comply with Building Regulations Document L, and offer a guarantee of their work.
Double-glazed units consist of two glass panes sealed hermetically with a space between them. This gap is usually filled with air or argon to improve insulation. The seal on the glass will last for the life of the window. However the condition of windows, the manner in which they were installed initially, and the chemical cleaning products that are used can influence the lifespan of the unit. Most of the time an un-sealed unit will fail because air enters the gap between the glass panes. This causes water to get into the gap and create condensation.
If a sealed unit fails, it is not possible to clean the window because it could damage the window and cause other problems like the risk of breaking the glass or more long-term issues like mildew and rot.

Repair
Double glazing is a favorite with homeowners due to its energy efficiency, noise reduction, and thermal insulation. Over time, windows can be weakened due to condensation, or a damaged seal. If the misting is extreme and the seal is damaged, replacement could be required. This process is expensive but it can improve the thermal efficiency of the window and lower your energy bills. The window experts at The Window Dr, serving Chichester, Wittering, Selsey, and Bognor Regis, offer professional evaluation and replacement of misted or blown sealed units.
A common problem is misting between glass panes of a double-glazed window. It happens when air gets warmer faster than the glass, causing it to reach its dew point and then form moisture on the bar that is inside the window. This moisture may then leak out of the window, causing a misty or fogging effect. The moisture can also cause the glass to become cloudy which may block the view and reduce the efficiency of windows.
The reason this issue occurs is due to a failure of the seal between the two glass panes of the double glazing. This issue could be caused by a variety of reasons like the age of the windows as well as the way they were initially installed. Sealants are not designed to last forever, and will wear down over time and allow gas or air (in the case of gas-filled units) to leak out, and water vapour to get in.

The reason why windows can be steamed or misty is because of a failure of the seals between the two glass panes in your sealed units. This could result from a range of factors including ageing, wear, the environment or a poor installation.
Temperature fluctuations can also lead to condensation. As the air cools, it becomes less humid. This causes moisture to build up on your window. This is why it's important to ensure that your windows are suited to the local climate and are properly installed and maintained by a FENSA approved window installer.
If your seals aren't functioning properly, it could mean that cold air is leaking out, as well as warm air escapes and this damages your window's energy efficiency. Replace any failed units before the winter season, so that you can improve the aesthetics and reduce the cost of heating.
