Are You Making The Most Of Your Misted Windows?
How to Prevent Misted Windows

The buildup of moisture in your double-glazed windows is a result of a variety of causes. The air within your living space is more vaporous than outside and can cause moisture to accumulate between glass panes.

This issue can significantly reduce the efficiency of your double glazing. If you don't address this issue, it will result in increased energy bills and damaged windows.

Condensation outside

If you spot condensation on the outside of your window frames, don't be concerned, it's completely normal. The condensation that forms on windows' exteriors is caused when humid, warm air comes into contact cold glass. The air's moisture cannot remain in vapour and, when it comes in contact with a cold object such as window glass, it transforms into water droplets (known as condensation). Exterior window condensation is typically seen in the morning, when temperatures are at a low level and sunlight isn't heating the windows to evaporate the moisture.

The good news is that condensation on the outside of your windows means your double glazing is working effectively and preventing heat from getting out of your home. The bad news is that excessive moisture from exterior window condensation can seep into the home and cause blistering, cracking or peeling paint on the window frames. This can lead to costly repairs and replacements, which is why it's crucial to keep the amount of moisture within your living space in control.

The good aspect is that a damp test conducted by a professional property inspector will pinpoint the source of the problem and recommend solutions that are cost effective.

Condensation inside

Sometimes, moisture can get trapped inside your windows, between the panes of glass. This type of condensation could be a problem, especially when it occurs in high humidity areas of your home (kitchen and laundry, bathroom). It is likely to be caused by a difference in temperatures of the outdoor and indoor air. The warmer air in the indoor cools down the window glass below its dewpoint, allowing water molecules to condense on the cold glass surface. This could cause visible fog or water droplets to appear on the glass.

Fogging is usually a sign of a failed window seal. The insulating materials between the window panes, for instance argon, are designed to prevent warmth from passing through the glass into the room. However as the seal gets weakened over time, moisture is capable of passing through. The result is a visible fog or condensation in the middle of the window, which makes it difficult to see out.

Moisture in between window panes is a problem because it can lead to mildew and mold that are both expensive to repair and harmful to your health. It can also cause rot in wood frames if it is not corrected immediately.

This will hold in moisture and prevent it dissipating rapidly.

If you notice condensation on the inside of your windows even in cold weather and when the air is dry, it could be time for a new double-glazed window with a more robust insulating material. You can also add inert gasses such as argon into your existing windows to reduce the likelihood of them reaching the dew point. This easy, cheap fix can make older, inefficient Windows much more energy efficient.
