Why is My Double Glazed Window Misted?
Double glazing is an excellent way to improve the efficiency of your property and ensure maximum energy efficiency. If you notice your windows misting it is an indication of a damaged window seal.
This will allow moisture to get into the insulation area of your window, which will drastically reduce the performance of your windows. Luckily, this problem is relatively simple to fix.
What is it?
It's possible to get condensation on your double-glazed windows, especially if it is very cold and stormy. This is a typical indication that your double glazed windows are securing the cold but also letting in warmth. You can clean it off or let it go away by itself.
If your double-glazed window is leaking on the inside it is more of an issue. This is typically a sign that the seal on your double glazing has broken down or 'failed' as it is called in the field. Moisture can enter between the two panes of glass in the case of a double-glazed unit that has failed. The argon, xenon, or krypton gases that are used in these units may also leak out. Once this occurs the high-density gasses lose their insulation properties and your window no longer functions as a sealed unit.
One of the primary reasons for the seal of a window to wear out is normal wear and tear over the years. This is due to the constant expansion and contraction of gases inside your double-glazed windows as temperatures change. Cleaning with chemicals that are abrasive on your double glazing could cause damage to the seal and lead to it failing over time too.
If the seal on your double glazed windows is broken, it means that warm air can escape from between the glass panes and cool air can get in, causing moisture to build up on the spacer bar within the glass unit. This is referred to as a "blown" window and could cause costly energy bills in winter.
Replacing the glass units of your double glazed windows can solve this issue. This is a far more cost-effective solution than replacing the entire window, and can guarantee that your home is properly protected and insulated. It is also important to ensure whether the company that is who is replacing your double-glazed windows is insured. This will safeguard you in the event of any unexpected problems.
Why is this happening?
Condensation inside double glazing isn't just unsightly but can also cause mildew which will deteriorate timber window frames. In extreme cases, black mould can grow on windows or cills. This isn't good for your family.
It is crucial to know the causes of condensation in order in order to determine how to best deal with it. Condensation occurs when the temperature of the glass is below the dew point - the point at which water vapour in the air transforms into liquid water. This is the reason it is most likely to occur during the night or early in the morning, when the dew point is at its highest and the air outside is warmer than the glass surface temperature.
As the weather turns colder and the humidity levels rise, condensation in double-glazed windows is more likely to happen as it is formed much faster. In the majority of cases it is a natural occurrence and does not indicate an issue with your double-glazing. If the condensation appears only on the outside of the window and disappears when the sun sets it is not a reason to worry.
Double-glazed damaged or broken windows won't effectively insulate your home as they should and this can result in more expensive energy bills. If the seals are damaged then moisture could pass through the two glass panes and eventually cause a misting effect.
The causes of the problems that lead to misted double glazing are numerous but there are some main causes that are worth looking for:
The first indication of a problem with your double glazed windows is usually when you start to observe condensation developing on the inside of the window. The next phase will be when you begin to observe water staining or damage to the glass that could be caused by moisture that is trapped between the two panes of glass. This could be due to damage caused during installation or just gradual wear and tear over time. This could be an indication that your window is approaching the end of its lifespan and needs to be replaced to enhance the insulation of your home.
How do I remove it?
Double glazing can increase the efficiency of your home's energy usage and also enhance the appearance of your windows. If your double glazing is cloudy or misty it could ruin the appearance of your windows. Fortunately, the solution to this issue is simple and cost-effective. Double glazing that has mist is the result of condensation or moisture entering the space between your double-glazed windows which must be airtight. This is usually a sign that the window seal has broken and requires repair.
misted window repair on the outside of new double-glazed windows is normal, especially during cold weather. This happens because the glass is chilled by air that has heated up and reached its dew point. When this water vapour reaches the cold surface of your windows it becomes visible, and then disappears once the glass warms up again.
It is only when double-glazed windows are smoky that you have to take action. The condensation suggests that the seal between the two glass panes has been damaged. It could also be a sign of poor installation or the use of chemicals in cleaning products.
To eliminate condensation on your double-glazed windows, there are several methods you can try. You can wipe them clean with a damp cloth to get rid of the condensation. You can spray them with glass cleaner specifically designed to get rid of condensation haze. You can also put in dehumidifiers at home to help absorb moisture and stop it from getting into windows.
There are professional solutions that can be used to fix your double glazed window mist. This involves drilling a small hole in one of the windows and then pumping into a desiccant that is specially designed, which will aid in drying out the window and prevent any further issues. This can be a risky procedure and should only be carried out by an experienced professional. This solution will restore the double-glazed windows to their original condition and will ensure that you don't suffer from condensation or misting issues in the future.
What is the most effective solution?
Condensation is common on the exterior of new double-glazed windows. This is a sign windows are functioning properly and can easily be cleaned away. The condensation is caused due to the temperature difference between the air in the house and the glass surface.
If you notice condensation between double-glazed glass panes, it is not normal. It is imperative to take immediate action. The window seal has broken and moisture has the ability to get into the space between the glass panes. This can cause windows to lose their insulation properties and will impact the efficiency of your home.
The best way to reduce condensation on your double-glazed windows is to increase the ventilation in your home. Opening the window on a daily basis will help to lower humidity levels and allow fresh air to circulate throughout your home. It is recommended to also make use of extractor fans in areas that generate lots of moisture, such as kitchens and bathrooms. Dehumidifiers can also be useful in actively removing excess moisture from the air and preventing it from condensing onto cold surfaces, like window glass.
Cleaning the window glass using anti-fogging products is another effective method to reduce condensation in double-glazed windows. These products are available in most hardware stores. They are designed to prevent the build-up of moisture. It is important to remember that these solutions aren't permanent and need to be reapplied periodically.
If your double-glazed windows are still under warranty, the best method to solve any issue with misting is to contact a professional installer. A FENSA-regulated firm will offer a 10-year warranty and adhere to UK Building Regulations.
