What is condensation?

The word condensation may remind you of your general science classes back in school! Condensation happens when water vapor comes in contact with a surface whose temperature is lower than its surrounding air. This simple concept causes dew on a hot humid day or rain falling from clouds on a cold day. 

Window Condensation

Window condensation is a commonly occurring phenomenon especially in winter that occurs when external temperatures drop and internal temperatures are warm. The warm water laden air comes in contact with the cold window surface resulting in condensation. This can be caused by faulty window panes or lack of air flow across a window surface that is covered. Whatever be the reason, if this is happening it is sign that your windows need your attention because the surplus moisture will be absorbed by the walls causing mold and mildew. Professional window installation goes a long way in preventing this condition. 

Managing Window Condensation

Window condensation can be attributed to several factors, poorly manufactured windows and inefficient sealing being most common of them. It is of utmost importance that the windows and doors are installed and sealed well. Here are a few ways you can avoid window condensation:

1. Ensure that your home is amply ventilated by switching on ceiling fans and exhaust fans in bathrooms and kitchens especially when you have hot liquids cooking or hot water running. This shall allow warm air movement preventing it from condensing.
    
2. Do not set the thermostat at very low levels as colder the air, the lesser is its ability to retain moisture encouraging it to condense and settle on windows and mirrors in your home. 
    
3. Invest in a hygrometer to measure the humidity levels inside your home that should ideally be between 35%-40%. Also it is wise to install a de-humidifier inside your house to regulate and manage humidity at optimum levels. 
    
4. If you notice condensation on a window, wipe it with a dry soft cloth to prevent excess moisture leaking into adjoining walls. 
    
5. Check seal of windows to ensure that there aren't any gaps. Also check for any cracks on glass panes that may cause condensation. If your windows are very old you can also consider replacing them for better heat retention. 

Flawed manufacturing of windows is often considered a major reason for condensation on your windows. But inability to manage internal humidity is also a cause for the same. So along with checking the condition of your windows, try controlling the moisture inside your home.
