How To Stop Window Condensation

Window condensation is annoying and potentially damaging. Here’s how to stop it.

What is condensation?

Condensation occurs when water vapour in the air comes into contact with a cool surface that reduces the energy in the particles to the point where they can no longer exist in steam form. Usually, you find condensation on cold surfaces, like windows, that are much cooler than the rest of the internal environment.

Most effective ways to stop window condensation

There are loads of things that you can do to reduce window condensation. Here are some of your options.

  • Use ceiling fans in the winter to circulate the air and provide fewer opportunities for vapour to condense

  • Open your windows to reduce moist air that could be trapped in your house, especially after showering or cooking with lots of boiling water

  • Increase the interior temperature to raise the temperature of the window panes around your home and prevent them from attracting moisture

  • Plants release moisture into the atmosphere, so remove them from your window sills

  • Buy a dehumidifier. These typically cost between £150 and £300

Best Glazing Options

One of the best ways to deal with condensation is to choose double or triple glazing. The reason for this has to do with the thermal properties of the window panes.

Double glazing creates a thermal barrier between the inside pane and the outside pane. The inside glass remains warm, like the interior of your home, and the outer pane is cold, just like the outdoor air. This combination prevents the formation of condensation.
