Misted Double Glazed Units
Double glazed units that have misted up occur when the glass inside begins to mist. It is usually due to the seals around the window unit breaking and causing moisture to draw in.
The most frequent reason for this is wear and tear from aging, but harsh cleaning chemicals can also damage the seals. Seals that are not properly maintained can lead to draughts, cold spots as well as damp and mildew issues down the road.
Age and wear
Double glazing is a great way to ensure that your home stays warm and comfortable throughout the entire year. However, older double-glazing units are prone to losing their effectiveness over time, and this can result in problems like misting windows.

The main reason for a misted window is due to the seal between the glass panes degrading. As temperatures increase and fall the gas in the double-glazed window expands or contract, placing pressure onto the seal. If this happens over a period of time, then your windows will start to experience moisture leaks and then eventually fail.
A damaged seal isn't just an a cosmetic issue It can also be damaging to your furniture and carpets as it allows unwanted condensation to enter your home. This can lead to your carpets and furniture losing their color and can be costly to repair.
Many homeowners are under the impression that replacing their windows is the best way to solve this issue, but this isn't always the situation.

Ventilation issues
Double-glazed windows are made up of two glass panes, separated by a spacer bar that acts as an efficient thermal barrier that is filled with air or gas. If the seal is damaged water can enter between the glass panes and cause misting. Misty double glazing isn't only unattractive, but also reduces the efficiency of your home's energy insulation.
There are a variety of reasons an item sealed may fail, but the general wear and tear is a major reason. Over time the seals may weaken due to temperature changes that causes them to expand and contract. Seals may deteriorate and eventually break down, allowing water into the window.
Poor installation is another reason for a failed sealing. This can cause issues like insufficient spacing blocks, gaps in the frames and a lack drainage. It can be caused by the use of harsh cleaning chemicals as well as the improper fitting of curtains.
Double glazed windows can be affected by humidity. The air's moisture forms a condensate on any cold surface. This is particularly true for a glass window. The moisture will fall down the inside window and form a condensation or fog.
