What Causes Window Condensation?

What is Condensation?

Condensation results in the presence of water/moisture on walls and windows: when you run your finger, it moistens. This arises due to contact between the air, which is saturated with water vapor, and the surface it settles on.

Contrary to popular belief, condensation problems are becoming more and more frequent as homes are more insulated, more heated, and less ventilated. Condensation particularly affects the kitchen and bathroom, two rooms heavily loaded with water vapor.

Different types of condensation

 

  • Outside the windows

 

The contact of this cold surface with hot air causes the appearance of this phenomenon.

 

  • Inside the glazing

 

Inside your window, you may frequently notice that condensation is developing. It is caused by your daily activities (shower steam, food, etc.) and does not pose a problem either since it also vanishes.

 

  • Between the two windows

 

Finally, the condensation that develops between your glass surfaces is more problematic since its presence is due to a defect or a leak in your frame. It doesn’t disappear over time and will prevent you from seeing through the window and may even damage the window.

What are the causes?

 

  • Insulation and airtightness

 

Condensation can occur due to air leaks. It is therefore essential that the insulation is well ensured during the installation of the frame, thanks to double glazing or shutters. Another factor to consider is airtightness.

 

  • Ventilation

 

Condensation also occurs when the ambient air is too humid. 

 

  • Heating

 

If your heating is located far from your windows and they are at least 6 ° C lower than the room temperature, you will still see condensation. Indeed, this phenomenon can occur when the hot and humid air comes into contact with a cold wall.

TIPS ON SOLVING CONDENSATION

 

  • Intervene on the glazing

 

If your window has single glazing, you can replace it with insulating glazing. This transformation mainly concerns materials such as wood or metal: more modern, PVC products generally have double glazing from the start.

 

  • Replace window

 

When the frame is not designed to be modifiable and is in poor condition, it is advisable to replace it to avoid heavier adaptations. The window wood or are more insulating than aluminum material or other metals.

 

  • Aeration

 

Always ensure that your room is well ventilated to reduce the risk of condensation.

  • By creating frequent drafts or by cross ventilation
  • By installing ventilators on the frame as well as a mechanical ventilation system
  • By installing a moisture absorber or dehumidifier 
  • By installing radiators under the frames. As the change from a gaseous state to a liquid or solid state occurs when the temperature of the chamber drops, it is advisable to keep the chamber constantly at 20 ° C.

However, if ventilating your rooms is not enough to eliminate condensation, it will be necessary to replace your windows. If this is the case, do not hesitate to contact Baystate Screen and Window, experts in window installation and repair services!
