Steamed Up Windows – Is it Normal?
It’s not unusual to find steam on your windows, especially during the colder months. While it might be a bit of an eyesore, it’s not always a cause for concern. However, if the steam is persistent, it could indicate underlying issues, potentially pointing to a more significant problem.
Why do windows steam up?
Steam on your windows, whether inside or out, is caused by condensation. When warm, moist air comes into contact with the cold surface of the glass, the water vapour in the air condenses into liquid droplets. This is most commonly seen in bathrooms or kitchens, where steam from hot water meets the cooler windowpane, resulting in visible condensation.
Preventing windows steaming up on the inside
Windows steaming up on the inside can be prevented by using effective ventilation in your home.
In the kitchen or bathroom, make use of your extractor fans to extract the damp air from the room before it hits the window.
If you are experiencing steam on the inside of windows elsewhere in the home, open a window slightly to let the air out and it will soon disappear.
It’s a good idea to prevent steam from occurring where you can, as, if left unchecked, it can lead to damp issues or damage to paintwork.
Windows steamed up on the outside
Condensation outside the window is perfectly normal and completely harmless.
In fact, it’s actually a sure sign that your windows are doing their job and preventing the air from entering your home while keeping the warm air inside the home.
Condensation inside the window pane
When you get condensation appearing inside the double glazing unit, this is generally bad news and will need attention from a professional expert.
It occurs because air is getting inside the unit and then condensing on one of the panes of glass. Over time, chemicals, such as those used in cleaning fluids, can break down the sealant around the panes, allowing the air to enter. However, if your windows are reasonably new, this issue could be down to improper installation or a fault with the supplied unit.
Windows becoming steamed up is a common occurrence in double glazing. Allowing for better airflow in rooms where steam is created will prevent this from occurring inside the home. However, in the case of windows steaming up inside the double-glazing unit, you will always need to get professional support from a double glazing installer.
