Why Is There Condensation On The Outside Of Windows?

The arrival of autumn and the impending winter weather means that temperatures have started to plummet, and you may have noticed condensation appearing around your home. Whether that’s a steamed-up bathroom mirror post-shower or droplets on the inside of your bedroom window in the mining, interior condensation is on the rise.

Condensation occurs during the colder months when the air outside is colder than inside and could be a sign that your home has above average humidity levels or a lack of ventilation. It can also occur in between the panes of glass in double glazing.

However, condensation can also appear on the outside of windows. If you want to know how and why condensation occurs, then we have the facts for your here.

Condensation forms when there is excess moisture in the air, as a result of everyday activities like cooking, showering or even just breathing. When the moisture in the air is in contact with an object that is cooler than the surrounding air, such as a window, the water molecules group together to create a thin layer of visible water droplets.

While drip marks caused by condensation on the outside of your windows can be frustrating, it isn’t a bad thing. If your windows are steamed up on the outside, it indicates that your double glazing is highly efficient, and is preventing any heat from escaping. You can wipe it away, but it will disappear over the course of the day.

However, interior condensation is a bit more of an issue, as persistent moisture will allow mould and mildew to form, which can be harmful to health and may cause damage to your property.
