How Condensation Can Affect Your Windows

The windows of your house are much more than just a barrier between the outside and your living space. They also help to regulate the temperature inside your home, let light and fresh air in, ensure proper ventilation and help you save energy.

Maintaining your windows is key to keeping them in the best condition and ensuring their longevity. One of the ways to take care of your windows is to watch out for problems like contamination, dirt, broken hardware and condensation. In this post, we explore how condensation affects your windows and what you can do about it.

What Is Condensation?

Condensation is the process of water vapour in the air turning back into a liquid when in contact with a cold surface. Water condenses and deposits on these cool surfaces when there are excess moisture and temperature differences between the air and surfaces. You will notice condensation on your windows when they turn foggy.

Interior Window Condensation

There will always be some amount of moisture in your indoor air if you heat your living space. Interior window condensation can happen when that moisture in the air deposits on colder surfaces like glass.

If the indoor air is humid and warm and the windows have a lower temperature, vapour in the air will reach the dew point when it comes in contact with the glass, turning back into water droplets.

Exterior Window Condensation

Exterior window condensation is similar to interior condensation, but it happens on the outside. It can happen when the outdoor air is warm, has a lot of vapour and comes into contact with the colder surface of your windows. Usually, this type of condensation occurs during the night and goes away once the sun rises.

Condensation outside your windows is less harmful to your windows than interior condensation, but you can reduce it by raising the indoor temperature to keep the glass of your windows warm.

Dual Pane Condensation

If you have double-glazed windows and notice condensation between the panes, you might have to replace your windows completely. Condensation between the two glass layers usually means that the seal is faulty.

Double-glazed windows should be less susceptible to condensation, as the air between the panes acts like thermal insulation. You can prevent condensation by using a dehumidifier, reducing vapour when cooking and drying laundry, and installing more efficient windows.

Can Condensation Damage Windows?

Several issues may arise if water condenses on your windows regularly. Increased humidity might lead to the growth of mould and mildew. Your windows can also get water damaged through prolonged exposure, which leads to peeling paint and faulty insulation, especially in timber windows.

Window Care and More

Regular maintenance of your windows should prevent most issues, including condensation. However, if you find that it’s a recurring problem, you might want to look into the effectiveness of your window and insulation and consider replacing them if they are beyond repair.
