Misted Up Double Glazed Unit Isn't As Tough As You Think
Why is My Double Glazed Unit Misting Up?

It's not a huge deal if condensation appears on the outside of double glazing. This is a sign that your windows work well and help keep heat inside your home. However, if it appears on the inside of your window panes, it is a problem that needs being addressed.

The presence of moisture between your windows means that the seals aren't working properly, leading to more expensive heating bills and less insulation. This can be the result of a variety of causes.

1. Faulty Seals

Mist that forms on the exterior of your windows is often caused by condensation that has made its way into the gap between the glass panes. The condensation is usually seen as a cloudy layer and reduces the transparency of your window. Misting inside your double glazing is much more severe and typically indicates that the seals on the insulating unit have failed.


This indicates that the seal has failed and moisture is leaking between the two panes of glass. This leads to fogging, and reduces the energy efficiency of your window. Double glazing that fails can also affect the appearance of your home, as well as the safety of your family members.

There are a variety of reasons that could cause your double-glazed windows to fail. These include natural wear and tear, defective installation or design issue with your window frame. It is essential to choose an experienced and reliable installation company that will guarantee their work, and not invalidate any warranty from the manufacturer.

One of the main reasons your double glazed units could fail is because they've become water damaged. This can be as a result of poor installation, or maybe a lack of drainage or spacer blocks. The moisture then begins to enter the building and, over time, cause the seals to fail and cause the formation of condensation between the glass panes.

A common cause of failure of a double-glazed unit is that the desiccant in the unit is saturated. The desiccant is designed to absorb excess moisture, preventing it from making its way into the space between the glass panes. But, when it becomes saturated, the desiccant will start to lose its ability to hold water and eventually the moisture between the glass will increase, causing the mist that is commonly observed.

The formation of moisture in the gap between the aluminium strip and the seal is often the first sign. It is important to note that this isn't a quick fix, and the best choice is to replace the entire unit. Hairdryers are a great device to use on a regular basis to get rid of condensation from your windows. This is especially effective in areas that have high humidity and condensation. A dehumidifier is an excellent option to add to your home to keep moisture out and keep it draught-free.

2. Poor Ventilation

Condensation may form on double-glazed windows due to a variety of reasons. If you spot condensation on the outside of your window, this is generally a good sign, as it indicates that your windows are functioning well and keeping cold air out and warm air in.

If condensation appears on the inside of your window, it is a sign that there may be there is a problem. This is because the condensation that forms inside your window indicates that the seals have failed and water may get into the glass panes.

This is usually due to inadequate ventilation. With no flow of air, the warmth in your home is trapped and this can cause condensation of moisture. This is most common in kitchens and bathrooms in which there is lots of moisture and humidity in the air. If you have a double-glazed window that is hazy it is important to examine the ventilation and reduce excess humidity in the area to prevent condensation from forming.

Double glazing seals that aren't functioning properly can increase the cost of energy. This is because your heating system will need to work harder in order to keep your home warm, and this could add up over time. Additionally, leaks in double glazing could allow cold air to enter your home, making it feel colder.

It's important to check your double-glazed windows frequently to ensure that the seals remain in good condition. If you clean your windows frequently using a non-chemical cleaner and don't allow them to get too wet and then there is a good chance that the seals will be in good condition for a long duration.

If you've recently installed double glazing and it is beginning to mist, this could be due to a poor installation.

It could be a mix of both and it's not unusual for double glazing to show some condensation on the outside, particularly if you are using a sealed unit that has high-quality Argon fill. However, this will go away as the glass gets warmer and air temperatures increase.

On the other hand, if you have condensation between the window panes, then there is a fault with the window and it must be replaced. Double-glazed windows that are not functioning properly don't insulate your home in the way they should. This could result in increased energy costs and even damage to the frame of the window.

A double glazed unit is an airtight and effective method of insulating your home whilst preventing condensation. The secret lies in the space between the two panes of glass, which is sealed in conditions of vacuum using inert gas or dehydrated air and is protected by primary and secondary seals. This helps reduce the loss of heat, keeping your home warmer and decreasing the cost of energy.

Over time, as a result of normal wear and tear, the seals on your double glazing can weaken allowing moisture to enter the space between the windows. This can be caused by various weather conditions. For example when temperatures fluctuate between high and low and the gasses in the units expand and contract. As time passes this causes the seals to break, allowing moisture into the cavity.

Window mist can not only affect your home's aesthetics however, they also decrease visibility. If they're not taken care of, they can also lead to the development of mildew and mould. This could be detrimental to your health and may cause damage to the frame of your windows.
