Why is My Double Glazed Unit Misting Up? It's not a big deal if condensation appears on the exterior of double glazing. This is a sign that your windows work properly and keep heat in your home. If it is visible on the inside of window panes there is an issue. Moisture trapped between your windows is a sign that the seals have failed, which means you will pay higher heating costs and lower insulation. This can be caused by several 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 cause of misting on the outside. The condensation is usually seen as a cloudy layer and reduces the transparency of your window.

The moisture can then seep into the seals, which causes them to fail over time. This can lead to condensation between the glass panes. Another common reason for a failed double-glazed unit is that the desiccant inside the unit is saturated. The desiccant is designed in order to absorb excess moisture, preventing it from making its way into the space between the glass panes. However, as it becomes over saturated the desiccant will start to lose its capacity to absorb water and eventually, the moisture between the glass will increase, causing the mist that is commonly observed. Moisture forming in the gap between the strip of aluminium and the seal is typically the first indication. This is not a simple solution and it is recommended to replace the entire unit. Hairdryers are a great device to use on a regular schedule to get rid of condensation from your windows. This is especially beneficial in areas of high humidity and condensation. A dehumidifier for your home is also an excellent way to stop the buildup of moisture and to keep your home draught free. 2.

If you spot condensation on the outside of your window, this is generally a good sign as it suggests that your windows are working well and are keeping cold air out and warm air in. If the condensation is inside the window, this could indicate an issue. The reason for this is that the condensation inside your window is a sign that the seals aren't working and moisture can get in between the glass panes. This is typically caused by poor ventilation. If there is no air circulation, the warmth in your home is sucked up and this can cause the humidity to rise. This is especially common in bathrooms and kitchens where there's an abundance of moisture and humidity in the air. If you have a misty double glazed window, you must inspect your ventilation and reduce any excess humidity in the room to stop condensation building up.
