Misted Double Glazing
Double glazing that has mist is a sign of weakened seals that allow moisture pass through the gap between the panes. This can affect the insulating qualities of your windows, and can cause a number of problems.
Condensation occurs when warm air comes into contact with cold surfaces and cools down to its dew point. When this process is not properly controlled, your windows will become hazy.
Reduce Indoor Humidity
If your double-glazed windows are prone to misting because of water or humidity in air. This condensation of water can occur on a cold surface such as the glass of your window.
If you want to prevent misting, keep the room well ventilated. Make use of extractor fans to reduce humidity in rooms that are hot. Keeping the humidity in these spaces low will keep condensation from forming on your windows.
A generous gap between double-glazed windows can aid in keeping them free of mist. If the gaps are too close, then moisture will be able to get in and the seal will break which can result in windows becoming misty.
It is also a good idea to leave the windows open as much as you can during the day, especially in summer. This will keep your home cool and fresh, and will also prevent warm air from escaping through the gaps.
It is also important to keep your blinds and curtains away from the windows. If cost of replacing misted double glazing units hang your curtains against the glass, condensation can build up. This will also cause misting in humid air.
Another important aspect of a window's ability to resist condensation is its insulation properties. Double-glazed windows are constructed of two separate glass panes that are bonded together and have an interlocking spacer bar. The spacer bar is constructed of dessicant which is designed to absorb and hold water vapour from the air. The silica in the spacer bar will release the water vapour when the window cools and prevents it from reaching the dew point.
The insulation of your windows may be negatively affected by a number of factors, including condition of your windows were initially fitted. Chemical cleaning products can also deteriorate the seals, allowing moisture inside and warm air out and this could result in your double glazing becoming smudgey. Use only FENSA-registered window fitters to minimise the risk. Also, always follow their recommendations.
Clean Your Windows Everyday
Double-glazed windows are simple to clean and should be cleaned frequently to prevent the accumulation of dirt. Clean windows let more light into your home. This reduces the need to raise the thermostat and can help to prevent condensation.
Spray a small amount (less than 1 teaspoon) of cleaning solution on the glass and then spray it with water. Use a microfiber cloth to rub away the cleaning solution and then dry the window with a dry microfiber towel. Use a microfiber cloth that is free of lint, because paper towels can leave behind lint and fibres on your windows. This can cause them to appear dirty. If you're unable to reach your windows with a ladder or a rod extension, a long rod and a squeegee can allow you to clean your windows even while standing on the ground.
The appearance of mist on the outside of windows is perfectly normal and occurs when the air cools down after getting warmer, and then reaches its dew point. This can happen to any surface that can cool down including glass and double glazed windows. It doesn't affect the performance of your window and is easily cleaned off.
If the condensation is on your windows, it could be a more serious problem and requires professional attention. This is usually caused by a faulty seal on the window which allows cold air to escape and moisture to get inside. The seal may be damaged due to the way windows were constructed, a cleaning solution that was used, or by age.

The good news is that the seals are still repairable, and you can have a high-performing double glazed home window.

It's usually caused by a damaged seal, but there are a few options you can take to prevent misting from forming like reducing humidity levels, increasing ventilation or using a humidifier. When misting occurs in between your windows, this is usually a sign of something more serious and is not fixable with temporary solutions.
Double-glazed windows consist of two panes that are separated by a small air gap. They are then sealed with a top-quality thermal barrier like argon gas to improve insulation. This makes the window extremely difficult to break. The air gap is then filled in by a secondary seal and a primary one, which enhances the thermal efficiency of the window and prevents moisture from getting into the window. However, over time these seals can break down due to a number of factors like the window's age, the manner in which they were put in place, and the use of chemicals used to clean the windows.
As the temperature drops outside, the water that is trapped in the air gaps turns into water vapour and forms a layer of fog on the window. The issue with this is that it lowers the effectiveness of windows as insulators by letting cold air in and warm air out and causing your heating bills to increase.
You've probably seen advertisements for companies that claim to fix misted glass double glazing by drilling small holes in the units, and then injecting anti-fogging chemicals into them. This removes moisture, but it's not a permanent fix. It is not recommended that this be carried out by yourself.
If the seals between your window panes are deteriorating and the glass has started to fog up It's likely that they'll need replacing completely. Replacing the window unit is more expensive than just cleaning the frame of your existing windows, but it will fix the problem and allow you to choose more energy-efficient double glazing to make your home even more energy efficient.
