Misting Double Glazed Repair
Misted double glazing is a common issue that can affect the performance of your windows and doors. It usually results from a breach in the seal, which allows moisture into that insulation section of the glass unit.

Seals
As time passes the seals that keep the inert gases between the two glass panes may be less effective. If the seals cannot be repaired the window will start to fog up because water vapour is accumulating between the glass panes. If left unchecked, this could cause a decline in the effectiveness of your window. This could result in higher energy bills and moisture getting into your home.

The main cause of double glazing condensation and misting is the inability of the primary seal between the glass panes, this could have happened because of damage that occurred during the installation or delivery process or simply wear and tear. It is important to have double-glazed sealed units inspected frequently. Mr Misty will re-seal the sealed unit to improve its insulating properties and stop issues like water and draught ingress.
This condensation can be caused by the spacer bar getting snared. This can be caused by many reasons, such as:
A good way to check if your spacer bars are slipping is to look for tiny black marks on the frame and cill. This is an indication of a spacer that is loose and is easily fixed using a flat-head screwdriver to push the corner keys to secure the end of the bar. They can be found on the outside of the frame and are easy to take off.
It is a good practice to clean the glass's edges where the beads were attached. This will stop the bead from sticking back to the glass after reassembling the window.

The most common cause of double glazing condensation is due to internal humidity and ventilation issues It is therefore essential to be aware of this and make adjustments accordingly. However, there are also some other factors that can contribute to this issue such as:
Fogging can occur if airborne moisture is not removed quickly. This moisture can also have an impact on the performance of windows which can result in lower efficiency in energy or higher heating and cooling costs.
Another factor that contributes to this problem is poor quality installation. Installers who aren't experienced may not seal the gaps between windows and frames properly and let moisture in the frame and result in condensation. It is essential to choose an FENSA-regulated contractor to ensure that your double-glazed window installation is of top quality and meets UK building regulations.

To provide more thermal insulation double-glazed windows are usually filled with Argon or other inert gases. This gas can help in keeping the window sealed and insulates it well, but if this gas isn't maintained regularly or the gas isn't totally inert, then windows will become less secure and condensation may form between the two panes of glass.
An easy fix is to use a hairdryer on the glass to evaporate any stagnant water droplets stuck in between the panes. Use a low-heat setting and stay away from seals as too much heat could cause them to melt, causing further damage. Defoggers provide a permanent solution for this problem. You can install one easily by drilling a small opening into the window, and then spraying the cleaning solution inside.
Ventilation
There are several methods to fix double glazing that is misty, based on how severe the problem is and how much you're willing to spend. Some companies will drill an opening between the panes and fit vents to allow the windows to breathe which helps with the escape of moisture. Other companies will employ anti-fog coatings or a combination of both of these methods to help with the prevention of condensation. In certain instances, replacing the window unit entirely may be the best option as it will help to solve the problem completely.
The mist that appears on double-glazed windows happens by air getting trapped between the panes of glass. This air is usually filled with argon that has a higher thermal efficiency. This gas creates an insulating barrier that keeps warm air inside and cold air outside. If the seals fail the argon could escape and cause windows to become misty.
The first signs of this are typically noticed in the morning when the moisture from the dew is able to condense against the cold glass. While this is a normal phenomenon and nothing to worry about, it does cause the double glazed window to lose some its insulating properties which can result in higher energy bills.
