Misted Double Glazing
Double glazing that is misted is an indication of compromised seals that allow moisture pass through the gap between the panes. This could reduce your windows' insulating properties and lead to a myriad of problems.
Condensation occurs when warm air is in contact with cold surfaces and cools to its dewpoint. When this process is not controlled effectively, your windows will become blurred.
Reduce Indoor Humidity
If your double-glazed windows mist, there's too much water or humidity in air. This water will condense when it comes into contact with a cold surface, such as the glass in your window.
If you want to avoid misting, reduce indoor humidity by keeping the room well ventilated and using extractor fans in areas that tend to be steamy, such as bathrooms and kitchens. In keeping the humidity of these spaces low will prevent condensation from forming on your windows.
A wide gap between your double-glazed windows will help keep them free of mist. If the gaps are too close, moisture can get in and the seal could break which can result in windows becoming misty.
It is also recommended to keep the windows open as much as possible during the day, particularly in summer. This will keep your home cool and fresh, and will also stop warm air from escaping through the gaps.
Also ensure that your curtains and blinds away from windows. If you hang your curtains against the glass, condensation will build up. This can also lead to misting in humid air.
The other major factor in windows' ability to resist condensation is its insulating properties. Double-glazed windows consist of two glass panes, which are sealed together and have an opening bar between them. The spacer bar is made of dessicant which is designed to hold and absorb water vapour from the air. When the window cools the silica releases the water vapour, which prevents it from reaching its dew point and creating mist to form.
The insulation of your windows can be affected by many factors, including their age and the quality of their installation. Chemical cleaning products can also harm seals. This can allow moisture to get in and warm air escape, which could cause your double glazing to become misty. Use only FENSA-registered window fitters to minimize the risk. Also, always follow their instructions.
Clean Your Windows Regularly
Double-glazed windows are simple to clean and should be cleaned frequently to prevent dirt buildup. Clean windows allow more light into your home. This reduces the need to increase the thermostat and can help prevent condensation.
Clean your windows by spraying them with water and a small amount of cleaning solution. Rub the solution to remove the cleaner with a microfiber cloth and dry the window with a microfiber towel. It is important to use a non-linty microfiber cloth as paper towels will leave behind lint and fibres on the windows which can make them appear dirty. If you're not able to reach your windows using ladders or a rod extension, a long rod and a squeegee let you to clean your windows even while sitting on the ground.
The appearance of mist on the outside of windows is normal and occurs when the air cools down after warming up, reaching its dew point. It happens to any surface that can cool down including glass and double glazed windows. It does not impact the performance of the window, and it can simply be wiped away.
If you notice condensation on your windows, this can be a more serious problem and requires professional attention. The reason for this is the window seal being defective, which allows moisture to get in and cold air to escape. The seal can be damaged by how the windows were initially fitted or by a chemical cleaning product used on them or even age.
When the seals of your double glazing break, it can compromise the efficiency of your home and lead to draughts and condensation. The good thing is that the seals are repairable and you will still have a the most efficient double-glazed window for your home. Double glazier repair companies like Mr Misty Ipswich can replace separate seals or gaskets that aren't completely intact to restore a reliable weather seal for your window. This can reduce water ingress, draughts and condensation, as well as preventing more serious issues like mildew, rot and damp.
Repair or replace the glass units
If water seeps into the air space between your double-glazed windows, it causes condensation and fog which can be ugly and decreases the energy efficiency of your home. It's typically due to a broken seal, but there are some options you can take to stop misting from occurring such as reducing the humidity levels, increasing ventilation, or by using a dehumidifier. However, when misting occurs between your windows, it's typically an indication of a bigger issue and can't be solved with temporary solutions.
Double-glazed windows are made up of two panes, 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 filled in with a secondary and primary seal, which improves the thermal performance of the window, and also prevents moisture from entering the window. Over time, these seals can break because of a variety of factors, including the age of the windows, the manner in which windows were constructed, and chemical cleaning products.
When it gets colder outside, the water in the air gaps turns into water vapour and settles as a layer of fog on the window. The issue with this is that it lowers the effectiveness of your windows as an insulator and allows cold air in and warm air out, making your heating bills increase.
You may have seen companies offering services that claim to fix misted double glazing by drilling holes in the glass units and then filling them with anti-fogging chemical. This will eliminate excess moisture, but it's not an all-time fix. It is not recommended that this be done by yourself.
If the seals on your windows are damaged, and the glass is hazy it could be necessary to be replaced completely. The replacement of the window unit is more expensive than just cleaning the frame of your current windows, but it will solve the issue and allow you to choose high-quality double glazing to make your home even more energy efficient.
