Why is My Double Glazed Unit Misting Up?

If condensation develops on the exterior of double-glazed windows, it is not a problem and in fact, it is a sign that your windows are operating effectively and retaining heat within your home. If it happens on the inside of your window panes, it is a problem that needs being addressed.

The condensation that is forming between your windows indicates that the seals have failed - leaving you with higher heating costs and lower insulation. This could be the result of a variety of causes.

1. The seals are not working properly

Condensation that has gotten into the space between the glass panes is the most common cause of misting appearing on the outside. The condensation is usually seen as a cloudy layer and reduces the transparency of your window. The misting inside double glazing is much more severe and indicates that the seals of the insulating unit are not working properly.

This means that the seal is broken and moisture has made its way in between the two glass panes, which is causing the fogging and reducing the efficiency of your window. A broken double glass can impact the overall appearance of your home, as well as the safety of your family.

There are many reasons why your double-glazed units could fail, such as wear and tear as well as a poor installation or problems with the design of your window frame. It is important to always use a reputable installer who will assure their work and not affect any manufacturer warranties.

Water damage is one of the most common reasons for double-glazed units to fail. This could be a result of poor installation, or maybe a lack of drainage or spacer blocks. The moisture is then able to seep in and, over time, cause the seals to break down which can lead to the beginning of condensation between the glass panes.

A common reason for a double-glazed unit failing is that the desiccant inside the unit becomes saturated. The desiccant is designed to absorb excess moisture, and prevent it from getting into the space between the glass panes. However, once it is saturated, the desiccant begins to lose its ability to absorb water and eventually, the moisture between glass will increase, causing the mist that is frequently seen.

A swell of moisture forming between the aluminium strip and the seal is often the first indication. It isn't a simple solution and it is recommended to replace the whole unit. Using a hairdryer on a regular basis is a great way to get rid of condensation from your windows. It can be particularly effective in areas where there are high levels of condensation and humidity. The addition of a dehumidifier in your home is an excellent way to prevent moisture build up and keep your home free of drafts.

2. Poor Ventilation

Condensation may form on double-glazed windows due to a variety of reasons. Condensation on the outside windows is generally an indicator of positive quality, as it indicates that your windows are operating well and keeping warm air inside and cold air out.

If condensation is visible on the inside of your window, it is a sign that there may be a problem. The reason for this is that the condensation that forms inside your window is a sign that the seals have failed and water can get in between the glass panes.

The reason is often poor ventilation in the room. If there is no air circulation, the warmth in your home is trapped and this causes moisture to build up. This is especially common in kitchens and bathrooms in which there is lots of humidity and moisture in the air. If you have a misty window double-glazed window, you must examine your ventilation and decrease the humidity levels in the room in order to stop condensation building up.

A failure to seal double glazing can cause an increase in energy bills. This is because heating systems will have to perform more efficiently to keep your home warm. This can add up. In addition, leaking double glazing can let cold air in your home, which can make it feel colder.

To ensure that your windows comply with UK building regulations, it is essential to choose a FENSA-certified installer. Incorrect installation can cause the window seals to fail, which could result in moisture to get between the panes. This will then eventually corrode the spacer bar made of aluminium and lead to the sealant in the unit degrading. This will cause the anti-moisture granules inside the spacer bar to be saturated with moisture and will no longer function as effectively as they should.

The presence of condensation on the side facing the room of your double-glazed units indicates that there is a ventilation problem in that particular space or property that needs addressing. It could be due to a combination and it's perfectly normal for double glazing to have some condensation on the outside, if you're using a sealed unit with top-quality Argon fill.

4. Age

Double glazed units are a reliable and airtight way of protect your home from condensation. The main reason is the gap created between the two panes. The gap is sealed using dehydrated gas or air under vacuum, and protected by secondary and primary seals. This greatly reduces heat loss and keeps the interior of your property warmer whilst reducing energy bills.

Over time due to natural wear and tear, the seals inside your double glazing may degrade leading to moisture making its way into the cavity between the windows. This can be caused by different weather conditions, like when temperatures fluctuate between high and low the gases inside the units expand and contract. Over time, this causes the seal to fail, allowing moisture in.
