Misted Double Glazing
Double glazing that is misted is an indication of compromised seals which allow moisture to pass through the gap between the panes. This can affect your windows' insulating properties and create a range of issues.
Condensation occurs when warm air comes in contact with cold surfaces and cools to its dew point. If this process isn't controlled effectively your windows will begin to become cloudy.
Reduce Indoor Humidity
If your double glazed windows are leaking the reason is that there is excess water or humidity in the air. The water will condense onto an unheated surface, such as the glass of your window.
If you're looking to stop misting, ensure that the area is cool and well ventilated. Make use of extractor fans to reduce the humidity in rooms that are steamy. This will help prevent condensation on your windows due to keeping the humidity low in these areas.
A large gap between your double-glazed windows will ensure that they are free of mist. If the gaps are too close, moisture can be able to get inside and the seal could break and cause windows to become misty.
In the summer months, it's recommended to keep the windows as open as possible. This will keep your home cool and fresh, and also stop warm air from getting through the gap.
Also make sure that you keep your curtains and blinds away from windows. If you hang your curtains on the glass, condensation will build up. This can also lead to misting in humid air.
Another major aspect in windows' ability to resist condensation is its insulation capabilities. Double-glazed windows are composed of two glass panes sealed together with the spacer bar between the glass. The spacer bar contains dessicant, which is designed to absorb and hold water vapour in the air. The silica in the spacer bar will release the water vapour when the window cools, preventing it from reaching the dew point.
The insulation properties of your windows can be negatively affected by a range of factors, including the age and how well your windows were initially fitted. The use of chemical cleaning products can also damage the seals, allowing moisture in and warm air out, and this could result in your double glazing becoming smudgey. To reduce the chance of this happening, only make use of FENSA certified window fitters and follow their instructions.
Clean Your Windows Everyday
Double-glazed windows are simple to clean and should be maintained regularly to avoid the build-up of dirt. Clean windows will allow more light into your home, which will reduce the need to increase the thermostat and also help keep condensation from forming.
Clean your windows by spraying the glass with water and a small amount of cleaning solution. Rub the cleaning solution off using a microfiber towel, and dry the window with a microfiber towel. Use a microfiber cloth that is free of lint, as paper towels can leave behind lint and fibres on your windows. This can cause them to appear dirty. If you're not able to reach your windows using ladders or a rod extension, a long rod and a squeegee can allow you to clean your windows even while sitting on the ground.
Misting on the outside of a window is perfectly normal and occurs when the air cools down after warming up, reaching its dew point. It happens to any surface that is able to cool down including windows made of glass and double-glazed windows. It doesn't affect the performance of the window, and it can simply be removed.
However, if condensation is forming inside your windows, it can be more difficult and require attention from an expert. It is usually due to an unsound seal on the window, which allows cold air to escape and moisture to get in. The seal could be damaged due to the way the windows were originally fitted, a chemical cleaning solution applied to them, or even aging.
When the seals of your double glazing fail, the efficiency of the window is diminished and could result in condensation, draughts and mildew. The good news is that the seals are repairable and you'll still be able to have the most efficient double-glazed window for your home. Double glazier repair services like Mr Misty Ipswich are able to replace any seals or gaskets that are damaged in order to restore an efficient weather seal. This can help reduce the effects of draughts, water intrusion and condensation, as well as preventing more serious problems such as mildew, rot, and damp.
Repair or replace the Glass Units
If water seeps into the air gap between your double-glazed windows, it can cause fog and condensation which looks ugly and lowers the energy efficiency of your home. It is possible to prevent misting by reducing humidity, enhancing ventilation, or using a humidifier. However, when misting occurs between your windows, it's often a sign of a more serious problem and cannot be solved with temporary solutions.
Double-glazed windows consist of two panes separated by a small air gap. They are then sealed with a high-quality thermal barrier like the argon gas for better insulation. This makes the window difficult to break. The air gap is then filled in with a second seal, as well as a primary one. This enhances the thermal efficiency of the window, and also prevents moisture from entering the window. As time passes, these seals could break down due to a variety of reasons, including age, the method in which windows were constructed, and chemical cleaning products.
The water that is in the air gap turns to water vapour when it is colder outside, and it gets deposited on the outside of the window in a cloudy layer of condensation. This decreases your windows' effectiveness as insulators by allowing cold air to enter and warm air to escape, increasing your heating costs.
You might have seen ads for companies that claim to fix misted double glazing by drilling small holes in the units, and then injecting anti-fogging chemicals into the units. This will remove the excess moisture but it's not a permanent solution and is not recommended that you try it yourself.
If your window seals are damaged and the glass is hazy, they may need to be replaced completely. It's more expensive to replace the window unit than to clean the frames of your current windows, but it will solve the problem and allow you to upgrade to higher-rated double-glazed windows.
