Misty Double Glazing - Is It Necessary to Replace Your Windows?
Double condensation on the glass can be ugly but it does not always mean you have to replace your windows. In most cases, a new sealed unit is enough.
Double glazing is filled with Argon gas between the two window panes which helps to control insulation and temperature within your home. If this gas is broken down, it can lead to misting windows and a loss of performance.
Repair
Double glazing is a highly efficient window solution, however when the window seals deteriorate, it allows moisture to get inside and create condensation and mist. If misty window occurs, the windows will not perform as they should and your home will lose heat, resulting in a higher cost for heating. Luckily, there are several solutions to the issue, including repair and replacement.
Double-glazing's efficacy is due to the structure of the two glass panes separated by a highly efficient thermal spacer bar. The spacer bar, together with the air or gas inside, creates an insulating barrier that helps keep warm air inside and keep out colder air. If this arrangement fails, and the window panes become blurred, the glass seal is usually damaged.
The seal may break due to various reasons, but normal wear and tear is the most frequent. As temperatures rise and drop, the seal expands or contracts and puts pressure on it until it is broken. This is a typical issue with older double-glazed windows but the seal may also fail due to problems with installation or the use of cleaning products.
If you notice that your double-glazed windows are leaking then it's time to seek assistance. This issue isn't easy to solve by yourself, so it is essential to engage a professional who can replace or repair the sealed unit and restore its performance. Choose a contractor with a good track record and who provides warranties on their work.
A double-glazed window that is misting is usually a sign that the glass unit or window frame itself is damaged. It may not be cost-effective or practical to replace the entire double-glazed window. However you can take out the damaged unit and replace it, which will remove the moisture build-up.
Although there are a lot of DIY techniques to clear your double-glazed windows of condensation, the best solution is to replace the window units with new ones. This will improve the functionality of windows and stop condensation by introducing proper insulation and sealing.
Replacement
If the misty double-glazing is only visible from the inside of the window, it's most likely caused by condensation. This can be fixed by rewetting the panes. If the mist is visible on both the outside and inside of your window it will most likely be an indication that the seal between the glass units has failed. In this situation, it's imperative to replace the unit.
If your double glazing is under warranty and was installed by an installer of your choice, they should solve the issue at no cost to you, based on the terms of your window warranty. The sealed glass units can be replaced to remove condensation and misting and improve their energy efficiency.
Replacing the sealed glass units inside your home will not only make it less draughty but also warmer and less expensive heating expenses. You may even be eligible to receive a grant or financial aid to pay for replacements.
The condensation outside of your windows is normal. It is a sign that your double glazing system is working effectively and keeping moisture away from your home. If however, you notice mist on the inside of your windows it is most likely a sign that there is an issue with your insulation and an issue with the seals between the glass panes.
The wood will begin to rot when moisture gets trapped between your windows. The exposure to excessive moisture could also lead to health issues such as respiratory infections, allergies and asthma. Repairing your double glazing or replaced as soon as you see the signs of condensation or misting is therefore vital for the long-term performance of your windows as well as the integrity of your property.

DIY
Double glazing that is misty is a frequent issue. This occurs when water vapour from the air gets in contact with a cool surface like the glass of your window. It is particularly noticeable during winter, when the temperature decreases and the humidity rises. It can damage the frame of your window, and can cause mildew and dampness, which can be both ugly and harmful.
Modern double glazing is composed of two panes that are sealed together with a gap in between them. A spacer bar with an absorbent desiccant is also used. The spacer bar is designed to keep cold air from your home and warm air inside, but can wear down as time passes. This could be due damage to the window frame, bad weather or harsh cleaning chemicals.
If the seal fails the window will not be able to hold its heat, and it will begin to leak. This can make you feel uncomfortable in your home and increase your heating costs. This can also impact the price of your home's resales, as buyers may be put off by poor quality windows.
Fortunately, replacing your double glazed windows isn't as expensive as it appears. In fact, it can be as low as PS500 for a new window. A new unit can provide the proper insulation and seal, which can help reduce condensation problems.
You can also use dehumidifying solutions on your windows and door to prevent condensation and misting. These products are available in spray form and can easily be applied to your windows. The spray will penetrate the glass and the spacer bar, taking up any moisture that is not needed. This can be done several times a day and is one of the most cost-effective ways to prevent condensation from forming in your double-glazed windows. Alternately, you could try placing a towel that has been soaked in vinegar between the glass panes to help absorb the moisture.
Warranty
Double glazing that appears to be misty could indicate an unsound seal, allowing moisture to pass through the panes. This could affect the insulation of your home, and may also lead to mildew or mold. This problem can be avoided by having your windows repaired as soon as possible. Depending on the conditions and the age of your windows, you might have to replace the window completely, but a professional can look into this and suggest the most appropriate option for you.
If you've had windows installed within the past few years and are still within warranty, it's worth calling the installers to inform them of the problem. The installers will often be able to rectify the problem without cost to you. It is also important to ensure that you are aware of the conditions and terms of your warranty so that you can be sure that it covers repairs or replacements that are required.
The most common reason for double glazed windows to become cloudy is because the desiccant (usually silica beads) in the spacer bar between the two glass panes is saturated and does not absorb moisture. This can be caused by wear and tear, or simply because of temperature fluctuations, as one side of the window is hotter than the other and condensation develops between the glass.
There are a variety of methods for removing condensation from double-glazed windows, including placing an unsoaked towel in vinegar between the panes of glass for a night. This is only a temporary fix, and windows will re-mist when the humidity increases in the room.
Another solution is to use a dehumidifying product that is specifically designed for double-glazed windows and doors. These products come in the form of a spray and can be applied to both sides of the window. It is crucial to remember that condensation is not just an inconvenience, but it could cause a variety of problems if left untreated, from mould and water damage to reduced energy efficiency and increased heat loss.
