Misted Double Glazing: What Nobody Is Discussing
Misted Double Glazing

Double glazing that is misted is an indication of compromised seals that allow moisture get into the gaps between the panes. This can affect the insulation properties of your windows, and can cause many issues.

Condensation occurs when warm air comes in contact with cold surfaces and then cools to its dew point. If this process isn't controlled your windows could become hazy.

Reduce Indoor Humidity

If your double-glazed windows are leaking the reason is that there is excessive humidity or water in the air. This condensation of water can occur on an unheated surface, such as the glass of your windows.

If you'd like to prevent misting, lower the humidity inside by keeping the space ventilated and installing extractor fans in rooms that are known to be hot such as kitchens and bathrooms. This will help prevent condensation on your windows, by keeping the humidity low in these areas.

A generous gap between your double-glazed windows will aid in keeping them free of mist. If the gaps between the window panes are too small the moisture could get in and the seal could be damaged, resulting in misty windows.

In the summer months, it's recommended to keep your windows as wide as you can. This will help keep your home cool and fresh, and will also prevent the warm air from entering through the gap.

Also, keep your blinds and curtains away from windows. If you hang your curtains over the glass, condensation will build up. This can also lead to misting in humid air.

The other major factor in a window's ability to resist condensation is its insulating properties. Double-glazed windows consist of two glass panes that are sealed together and have a spacer bar between them. The spacer bar is constructed of dessicant that is designed to hold and absorb water vapour from the air. As the window cools, the silica will release the water vapour, which prevents it from reaching its dew point and cause mist to form.

Your windows' insulation could be affected by many aspects, such as their age and the quality of their installation. Chemical cleaning products can also harm the seals, allowing moisture inside and warm air out and this can lead to your double glazing getting misty. To reduce the chance of this happening, only make use of FENSA certified window fitters and always follow their directions.

Clean Your Windows Regularly

Double-glazed windows are simple to clean and should be maintained regularly to avoid the build-up of dirt. misted double glazing repairs allow more sunlight into your home, which will reduce the need to crank up the thermostat and also help prevent condensation.

Spray a small amount (less than a teaspoon) of cleaning solution onto the glass, and then spray it with water. Utilize a microfiber cloth to rub away the solution for cleaning and then dry the window using a dry microfiber cloth. Make sure you use a microfiber fabric that is lint free, as paper towels can leave behind lint and fibres on your windows. This can cause them to appear dirty. If you are unable to access your windows using a ladder, you could invest in an extension pole and a squeegee that will allow you to clean your windows without having to step on them.

Misting on the outside of windows is perfectly normal and occurs when the air cools after getting warmer, and then reaches its dew point. It can occur on any surface that is capable of cooling down, such as windows with double-glazed glass. It does not alter the performance of the window and it can simply be removed.


If you notice condensation on your windows, this can be a bigger issue and will require professional assistance. This is typically caused by an unsound seal on the window, which allows cold air to escape and moisture to get in. The seal may be damaged because of the manner in which the windows were installed, a cleaning solution that was used, or by age.

When the seals of your double glazing fail they can affect the efficiency of your home and cause draughts as well as condensation. The good news is that the seals are still repairable and you can get an energy efficient double-glazed home window. Double glazier repair companies such as Mr Misty Ipswich can replace separate gaskets or seals which aren't completely intact to reintroduce an effective weather seal for your window. This can reduce draughts and water infiltration as well as condensation and prevent more serious problems like mildew, rot, and damp.

Repair or replace the glass units

It's not just unsightly but also reduces the efficiency of your home's energy usage. You can stop misting by reducing humidity, enhancing ventilation, or using a humidifier. However, when misting occurs between your windows, it's usually a sign of a more serious problem and cannot be fixed with a few temporary solutions.

Double-glazed windows consist of two panes separated by a small air gap. They are then encased with a top-quality thermal barrier such as argon gas to increase insulation. This creates a window which is extremely hard to break. The air gap is then filled in with a second seal and a primary one, which enhances the thermal efficiency of the window and blocks moisture from entering the window. Over time, the seals could break down because of a variety of factors, such as age, the way the windows were installed and the use of chemical cleaning products.

As the temperature drops outside, the water that is trapped in the air gaps transforms into water vapour and settles as a layer of fog on the window. The issue with this is that it reduces the effectiveness of windows as insulators by letting cold air in and warm air out, the heating costs to increase.

You may have seen companies offering services that claim to fix misty double glazing by drilling holes into glass units and then filling them with anti-fogging chemicals. This will eliminate excess moisture, but it is not an all-time fix. It is not recommended that this be carried out by yourself.

If the seals on your windows are damaged and the glass is foggy it could be necessary to be replaced completely. It's more costly to replace the window unit, than cleaning the frames of your current windows but it will fix the problem and enable you to upgrade to higher-rated double glazing.

It is essential to address any condensation problems, regardless of whether they're on the outside or inside of double-glazed windows. If you do not act promptly this could lead to further damage to the window as well as a reduction in the effectiveness of your home's energy insulation.
