Double misting of the glazing is a issue that affects the majority of modern doors and windows. This occurs when a sealed unit breaks down and moisture gets into the gaps between the glass panes.

There are numerous solutions to this issue including drilling and draining the gaps to complete replacements, but it is essential that any work is performed by a skilled trade professional who will comply with Building Regulations Document L, and will provide a warranty of their workmanship.
Double-glazed units consist of two glass panes which are hermetically sealed together with a gap between them, which is usually filled with argon or air gas to enhance the insulation properties. The seal on the glass is designed to last the life of the window, but the window's age, the way they were installed, and any chemical cleaning products employed will affect the lifespan of the seal. The majority of cases where the seal breaks down it will be caused by air ingress. This results in water leaking into the gap and creating condensation between the glass panes.

Repair
Double glazing is a favorite among homeowners for its energy efficiency, noise reduction, and thermal insulation.

Misty glass between the panes of a double-glazed window is a typical problem. This happens when the air is heated faster than the glass and attains its dew point, which causes moisture to form on the spacer bars inside the window. The moisture then escapes from the window, creating a misty or fogging effect. The humidity can also cause the glass to become cloudy which may block the view and make the windows less effective.
This problem is caused by a problem in the seal between the glass panes. This could be due to various factors, such as age and the manner in which windows were installed originally. Sealants aren't made to last forever, and they will wear out over time and allow gas or air (in the case of gas-filled units) to escape, and water vapour to get in.
As winter is approaching it is essential to address any issues with your double glazed windows before the cold weather begins to set in.

Begin by carefully taking the top glass pane of the frame. Place the bottom pane on a workbench and scrub it thoroughly using a glass cleaner that you can purchase or paper kitchen roll.

They can be bought at the local hardware store and simply inserted into the sealed unit to remove moisture and prevent condensation from developing. However, we don't recommend this for the long-term, as moisture can seep into the frame and cause issues such as damp, mildew, or rot.
Windows that are misted can cause a lot of stress for homeowners, as they reduce the amount of light that enters your home, causing huge energy losses. In addition, if the windows are made of timber, they could be susceptible to issues such as damp and rotting if not properly maintained.
