Fogging can occur when airborne moisture is not removed quickly. This can also affect the performance of the window, leading to lower energy efficiency and increased heating or cooling costs.

Another major contributor to this issue is poor quality installation. Installers who aren't skilled may not close the gaps between the frames and window panes properly and let moisture in the frame and result in condensation. If you're having windows with double glazing installed it is recommended to employ a FENSA regulated fitter to ensure that the installation is of the highest quality and complies with UK building regulations.

When a double-glazed window is made and installed, it is usually filled with an inert gas like Argon for additional thermal insulation. This gas helps to keep the window sealed, and also helps to insulate the window well. However, if the inert gas isn't replaced frequently, or if the gas is not fully inert, windows may lose their tightness and condensation could develop between the glass panes.

A simple solution is to apply a hairdryer to the glass to eliminate any stagnant water droplets stuck between the panes. Make sure to use a low-heat setting, and stay away from seals since too much heat may cause them to melt, causing further damage.

In certain situations, replacing the window unit completely could be the best choice since it will help eliminate the problem once and for all.

Mist in double-glazed windows is caused by air that is trapped between the glass panes which is typically filled with argon gas to provide an extra thermal efficiency. This gas creates an insulating barrier that keeps warm air within and cold air outside. When the seals fail the argon escapes and cause windows to mist.

The first symptoms of this are usually observed in the morning, when the moisture of the dew begins to condense against the cold glass. Although this is a normal event and nothing to be concerned about, it does cause the double-glazed window to lose some of its insulation properties, which could result in higher energy bills.

The gasket, or seal which is responsible for holding the two glass panes in place, can also be broken due to a hairline crack or fracture. This could cause the glass that is insulated to depressurize and allow moisture to build up between the panes.
