Moisture condensation occurs on a window when the temperature of the inside surface is colder than the dewpoint of the air next to the window. Thus, this happens when the cold air outside and the warm air inside meet at the window. Aluminium windows are known for their strength and are most common in mild and warm climates. However, non-thermal break aluminium windows offer no increased condensation control and thus are prone to condensation. Fortunately, there are some things you can do to combat this.

Skill level:

Things you need

  • Exhaust fan
  • Dehumidifier
  • Hygrometer

  1. 1

    Increase ventilation in the room or rooms with the non-thermal break aluminium windows. Open windows and doors, run an exhaust fan or move draperies and other treatments away from the windows during the day.

  2. 2

    Remove moisture from the air inside. Run a dehumidifier to make the air near the window surface drier. Dehumidifiers are designed to remove moisture from the air and you can purchase one with a hygrometer so you can gauge the relative humidity in your home at all times.

  3. 3

    Reduce moisture-generating activities. You can prevent condensation on your windows simply through changing some of your habits. For example, take shorter showers, do not operate a humidifier in cold weather, do not water houseplants excessively and vent clothes dryers outdoors.

  4. 4

    Improve the thermal quality of the window. Your non-thermal break aluminium windows are not designed to prevent condensation. On the other hand, thermal windows, insulated windows and storm windows contain multiple panes of glass which help prevent the cold air outside from coming into contact with the warm air inside and creating condensation. When looking to improve the thermal quality of the window, be sure to purchase glass with a high condensation rating (CR). The National Fenestration Rating Council determines CR ratings, which range from 0 to 100. The higher the number, the better these windows are at preventing condensation.
