Why is My Double Glazed Unit Misting Up? It's not a big deal if condensation appears on the outside of double glazing. This indicates that your windows work well and help keep heat inside your home. When it appears on the inside of windows it's a sign of an issue. The presence of moisture between your windows indicates that the seals have failed – which means you will pay higher heating bills and reduced insulation. This could be due to various factors. 1. The seals are not working properly Condensation that is able to get into the space between the glass panes is the most common reason for misting appearing on the outside. Usually, the condensation appears as a cloudy coating and decreases the transparency of your window. The misting inside double glazing is much more serious, and suggests that the seals of the insulation unit are failing. This is a sign that the seal has failed and water is leaking between the two panes of glass. This leads to fogging, which reduces the efficiency of your window. Double glazing that fails could also affect the appearance of your home, as well as the safety of your family. There are a myriad of reasons your double glazed units can fail, including natural aging and wear an improper installation or issues with the design of your window frame. It is important that you select a reputable installation company who will warrant their work and not invalidate any warranty from the manufacturer. Water damage is among the most common causes for double-glazed units to fail. It could be due to poor installation, or a lack of drainage or spacer blocks. The moisture is then able to enter the building and, over time, cause the seals to break down and cause the formation of condensation between glass panes. Another common reason for a failure of a double glazed unit is that the desiccant in the unit becomes saturated. The desiccant absorbs moisture and stops it from getting into the gap between glass panes. As it becomes saturated the desiccant is unable to absorb moisture and the amount of moisture between the panes will grow. A swell of moisture forming between the aluminium strip and the seal is usually the first sign. It is important to remember that this is not an easy fix and the best option is to replace the entire unit. Hairdryers are a great device to utilize on a regular basis to eliminate condensation from your windows. This is especially beneficial in areas with high humidity and condensation. Adding a dehumidifier to your home is also a great way to help keep moisture from building up and keep your home dry. 2. misted window repairs can form on double-glazed windows for various reasons. Condensation on the outside of a window is usually an indication of good things, since it means that your windows are working well and allowing warm air inside and cold air out. If condensation appears on the inside of your window, it is an indication that there could be a problem. The condensation that forms inside your windows is a sign that the seals are damaged and moisture may get in between the glass panes. This is typically caused by inadequate ventilation. The heat in your home may be trapped if there's no air flow. This can result in moisture buildup. This is especially common in kitchens and bathrooms where there is lots of humidity and moisture in the air. If you have a misty double glazed window, it's essential to inspect your ventilation and reduce any excess humidity within the room to stop condensation from forming.

Installation error If your double-glazed windows have been installed recently but is already beginning to cloud up, it could be due to poor installation. To ensure that your windows are compliant with UK building standards, it is crucial to choose a FENSA-certified installer. Incorrect installation could cause the seals on the window panes to crack and allow moisture to enter between. This could cause the spacer bars to corrode, resulting in the sealant within the unit failing. This can cause the anti-moisture granules inside the spacer bar to become saturated with moisture and no longer work as effectively as they are supposed to. If you see condensation on the side facing your room, it means that there is a problem with ventilation in that space or property. It could be due to a combination and it's not unusual for double glazing to have some condensation on the outside, if you're using a sealed unit with high-quality Argon fill.

As time passes, due to natural wear and tear, the seals within your double glazing can deteriorate and allow moisture to make its way into the space between the windows. This could be due to a range of weather conditions, for instance when temperatures fluctuate between high and low the gases inside the units expand and contract, and over time, this causes the seal to weaken and allow moisture in.
