What Causes Condensation On The Outside of Windows?

Winter condensation can be a lot different from summer condensation. While you can observe winter condensation on the inner surface of your windows, summer condensation is an outside phenomenon. 

Generally, condensation happens when a cold surface collides with warm air. Likewise, humidity can also cause condensation on the outside of windows. This condition is common in the winter and autumn seasons, especially in the evenings and mornings.

Running the dishwasher, drying clothes, or cooking can also contribute to household condensation and leave you with wet streaks on the inner surface of your windows.

However, summer condensation is different. Unlike winter condensation, which appears on the inside, summer condensation occurs outside the windows. 

Causes for condensation on outside of windows include:

  • You could have just replaced old doors and windows
  • Installing and Siding a New Roof
  • Minimal air filtration 
  • High outdoor humidity
  • Morning after a cold night

How to get rid of condensation on outside of windows?

You can control or get rid of condensation using several measures. However, reducing interior window condensation may require a different approach than exterior window condensation. 

Since you have to follow different interior and exterior window condensation approaches, we will provide some measures to control condensation for both situations.

Ways to reduce interior window condensation:

  • By using a dehumidifier. You can install a whole-home dehumidifier to reduce air moisture
  • By utilizing a kitchen exhaust fan or a kitchen chimney
  • By covering pans and pots while cooking
  • By keeping your bathroom fan on while taking showers
  • You can increase air circulation by maintaining a schedule to open interior doors and windows.

Ways to reduce outside window condensation:

  • By removing or opening window coverings at night. Window coverings can trap moisture, which can cause condensation on windows. By removing or opening window coverings at night, condensation will not be able to form on the windows.
  • Ensure that you keep your windows and doors clear of obstacles to promote air circulation.
  • By raising your air conditioners temperature. When the air conditioner’s temperature is lowered, the water vapor in the air will condense on the cold surface. Increasing the temperature will cause water to evaporate more quickly, leaving less water vapor in the air for condensation.
  • By upgrading or replacing your windows. With the cost of heating a house skyrocketing, it’s important to examine your windows and see if it might be time for an upgrade. Properly installed and insulated windows can not only save you up to 30% on your energy bills, but also contribute to a better indoor air quality by minimizing the amount of pollutants that come in from the outside.

Why condensation on outside of windows is bad?

Condensation can lead to many different issues in a home. One of the most common is increased humidity levels. This can lead to mould, mildew, dust mites, bugs that look like lint, and other allergens in the air. If you have an older home with walls that are too thick or thermal bridges (weak spots that allow for heat transfer), it may also be easier for condensation to form and cause water damage.

Everyone knows the problems caused by mould and mildew. These fungal species can cause discolouration of your walls and cause health issues. Additionally, the appearance of black dots around your windows may not be an appealing first impression for your guests.

A rise in humidity level inside your home is also the reason for condensation. When the sun’s heat evaporates condensation, you house will soak up some of that moisture which will increase the overall humidity. It is a common sight during the cold winter months, where condensation on windows can often be seen.

Some other problems related to condensation include:

  • Condensation takes time to clear and you will need natural forces like sunlight or human labor to eliminate it.
  • Condensation can cause adverse effects on your health due to mildew and mold growth.
  • It can raise your home’s humidity levels
  • Condensation can visually diminish your window’s aesthetics with a cloud of tiny black dots
  • It can damage your walls and windows to a point where you have to replace the entire unit
  • It can lead to costly repairs and renovations

Which Windows Are Best To Prevent Condensation – Single Glazed or Double Glazed?

During the winter season, there is lots of condensation on windows in the morning. Condensation on windows is common for homes using a single glazed glass as it fails to provide adequate insulation.

Double glazed glass is more efficient and comes with a vacuum layer that promotes better insulation. Additionally, you can laminate this glass to protect your house from harmful UV rays. 

Benefits of Double Glazed Windows:

  • It increases energy efficiency
  • It maintains interior temperature
  • It puts minimal stress on air conditioners or heat pumps to sustain the room temperature
  • It reduces heat loss
