Why is My Double Glazed Unit Misting Up?

When condensation appears on the exterior of double-glazed windows, it is not an issue and in fact, it is a sign that your windows are functioning effectively and retaining heat within your home. If it is visible on the inside of window panes, it is an issue.

If you notice that there is moisture between your windows, it is a sign that the seals are failing. This can lead to higher heating bills and lower insulation. This could be due to several factors.

1. Faulty Seals

Mist that forms on the outside of your windows is typically caused by condensation that has made its way into the gap between the glass panes. Usually, the condensation appears as a cloudy layer and decreases the transparency of your window. The misting in double-glazed windows is much more severe and suggests that the seals of the insulating unit are failing.

This is a sign that the seal is broken and water is leaking between the two glass panes. This leads to fogging, and reduces the energy efficiency of your window. Double glazing that is not functioning properly can affect the overall appearance your home, as well as the safety of your family members.

There are a variety of reasons that could cause your double-glazed units to fail. They could be due to natural wear and tear, a faulty install or design issues with your window frame. It is essential to choose an experienced and reliable installation company that will warrant their work and not void any warranties from the manufacturer.

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

Another common reason for a failed double-glazed unit is that the desiccant in the unit becomes saturated. The desiccant is designed to suck up excess moisture, preventing it from getting into the gap between the glass panes. However, once it is saturated, the desiccant will lose its ability to absorb water and eventually, the moisture between glass will increase, causing the mist that is frequently observed.

Often the first sign of this is when you start to notice that moisture is forming on the aluminum strip inside the gap. It is important to remember that this is not a quick fix, and the best option is to replace the entire unit. Hairdryers are a great tool to use on a regular schedule to get rid of condensation from your windows. This is especially effective in areas of high humidity and condensation. A dehumidifier is a great addition to your home to stop the build-up of moisture and to keep it dry.

2. Poor Ventilation

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

However, if condensation appears on the inside of your window, it is an indication that there could be a problem. The condensation inside your windows means that the seals are broken and water can get inside the glass panes.

This is typically due to poor ventilation. If there is no air circulation the warmth inside your home is trapped and this causes the humidity to rise. This is typical in kitchens and bathrooms where there is a high level of humidity. If you have a double-glazed windows that is misty it is important to check the ventilation and reduce the amount of humidity in the area to prevent condensation from building up.

Double glazing seals that aren't working properly can also increase the cost of energy. It's because the heating system will need to be more efficient to keep your home warm. This could add up. Double glazing that leaks could allow cold air into your home and make it feel colder.

3. Installation error

If your double glazing has been installed recently but has already begun to fog up, it could be the result of poor installation. It is crucial to choose an FENSA certified installer to ensure that your windows are compliant with UK building regulations. A poor installation could cause the seals on the window panes to crack, allowing moisture to get in between. This will eventually cause the internal aluminium spacer bars to corrode, resulting in the sealant inside the unit failing. The anti-moisture grains inside the spacer bar will be saturated by water and cease to function efficiently.

If you notice condensation on the side facing your home, it indicates that there is a ventilation issue in the room or home. It could be a combination and it's normal for double glazing to show some condensation on the outside, especially if you are using a sealed unit with high-quality Argon fill. However, it will go away as the glass warms up and the temperature of the air rises.

The lifespan of a double glazed window should be between 10-35 years, however a variety of factors can cause them to fail earlier than this. A leaky seal allows moisture to get into windows, causing them to fog up or mist. This can be caused by a number of reasons, including:

4. Age

Double-glazed units are an effective and airtight method of protect your home from condensation. The secret lies in the space between the two panes of glass, which is sealed in vacuum conditions using dehydrated gas or inert gas and protected by primary and secondary seals. This reduces heat loss, keeping your home warm and reducing your energy costs.

As time passes, due to normal wear and wear and tear, the seals of your double glazing could weaken allowing moisture to enter the space between the window panes. This could result from different weather conditions. For example when temperatures fluctuate between high and low, the gases in the misted units expand and contract. Over time, this causes the seals to degrade and allow moisture to enter the cavity.

It's worth noting that windows with mists don't only affect the appearance of your home, they also decrease visibility and can lead to an increase in mould or mildew if left unchecked. This can be dangerous to your health and could cause damage to the window's frame.
